What is a heat sink?
If the fluid medium is water, the heat sink is usually called a cold plate. In thermodynamics, a heat sink is a heat storage device that can absorb any heat without significantly changing the temperature.
Can You chain vape with an Atty/heatsink?
So I have a head sink from a laser that's just about a perfect fit for an atty which I use for aesthetic purposes. I laid the mods atty/heatsink on a chunk of ice and started vaping and the vapor production was off the charts. You could chain vape all you wanted. 3 drops of juice was burned dry in under a minute chain vaping massive plumes of fog.
What is the difference between a heat sink and a heat exchanger?
These are inexpensive, medium performing and are limited in air-flow management. A heat sink is a passive heat exchanger, and it is designed to have large surface area in contact with the surrounding (cooling) medium like air.
What is a hybrid heat sink?
- Hybrid heat sinks combine some aspects of passive and active heat sinks. These configurations are less common, and they often rely on control systems to cool the system based on temperature requirements. When the system operates at cooler levels, the forced air source is inactive, only cooling the system passively.
What does heat sink mean?
heat sink. A protective device that absorbs and dissipates the excess heat generated by a system. An environment capable of absorbing heat from substances within it (and with which it is in thermal contact) without an appreciable change in its own temperature and without a change in its own phase.
Is vaping hot air?
Vapes are literally designed to get hot. Your battery is there to supply energy to a coil, which turns a portion of that energy into heat and, as a result, send a stream of vapour up the mouthpiece for you to inhale.
Can your lungs heal from vaping?
Breathing in the harmful chemicals from vaping products can cause irreversible (cannot be cured) lung damage, lung disease and, in some cases, death. Some chemicals in vaping products can also cause cardiovascular disease and biological changes that are associated with cancer development.
What are 5 negative effects of vaping?
The most commonly-reported adverse effects were throat/mouth irritation, headache, cough, and nausea, which tended to dissipate with continued use....Coughing, dry throat, headachescoughing.dry mouth and throat.shortness of breath.mouth and throat irritation.headaches.
What is a Heat Sink?
A heat sink is a component that increases the heat flow away from a hot device. It accomplishes this task by increasing the device's working surface area and the amount of low-temperature fluid that moves across its enlarged surface area. Based on each device's configuration, we find a multitude of heat sink aesthetics, design, and ultimate capabilities. You can see a straight fin heat sink in the image at the top of this article and a flared fin heat sink in the image below. Each heat sink is valuable in applications that may have varying:
How does a heat sink work?
A heat sink works by moving heat away from a critical component. Nearly all heat sinks accomplish this task in four basic steps: 1. The source generates heat. This source may be any system that creates heat and requires the removal of said heat to function correctly, such as: - Mechanical. - Electrical.
How does a fan affect a heat sink?
The fan forces air across the heat sink, which allows more unheated air to move across the heat sink surface, thus increasing the total thermal gradient across the heat sink system and allowing more heat to exit the overall system. - Hybrid heat sinks combine some aspects of passive and active heat sinks. These configurations are less common, and ...
How does heat travel through a heat sink?
Heat will naturally travel through the heat sink via natural conduction moving across the thermal gradient from a high temperature to a low-temperature environment. This ultimately means that the heat sink's thermal profile will not be consistent. As such, heat sinks will often be hotter towards the source and cooler towards the sink's extremities.
What happens if the ambient temperature is not cooler than the heat sink?
Therefore, if the ambient temperature is not cooler than the heat sink, no convection and subsequent heat removal will occur . This step is also where the total surface area of the heat sink becomes most advantageous. A large surface area provides an increased area for thermal diffusion and convection to occur.
How does heat move away from a heat sink?
Heat moves away from the heat sink. This process relies on the heat sink's temperature gradient and its working fluid―most commonly air or a non-electrically-conductive liquid. The working fluid passes across the surface of the warm heat sink and utilizes thermal diffusion and convection to remove heat away from the surface and into ...
What material is used to make a heat sink?
The heat sink material's thermal conductivity directly impacts this process. That's why high thermal conductivity materials such as copper and aluminum are most common in the construction of heat sinks. 3.
What is a Heat Sink?
Heat sink is an electronic component or a device of an electronic circuit which disperses heat from other components (mainly from the power transistors) of a circuit into the surrounding medium and cools them for improving their performance, reliability and also avoids the premature failure of the components. For the cooling purpose,it incorporates a fan or cooling device.
What is a stamped heat sink?
Stamped Heat Sinks. These are made of metals that are stamped to form a particular shape. This stamp creates the heat sinks whenever metal is moved through the stamping machine. These are cheaper compared to extruded heat sinks. These are used for low-power applications and hence these are low in performance.
What is the thermal conductivity of aluminum heat sinks?
heat transferring capacity of the heat sink will also increase. Aluminum Heat Sink. The thermal conductivity of the aluminum is 235 W/mK; it is the cheapest and lightweight metal. Aluminum heat sinks are also called as extruded heat sinks as they can be made using extrusion.
What is the most common metal used in a heat sink?
Aluminum Heat Sink. Heat sinks are generally made of metals; and, aluminum is the most common metal used in heat sink.We are aware of the fact that the thermal conductivity of each metal is different.The thermal conductivity of metal is proportional to the heat transfer in heat sink. Thus, if the thermal conductivity of the metal increases, ...
What are passive heat sinks made of?
These do not possess any mechanical components and are made of aluminum finned radiators. These dissipate thermal energy or heat by using the convection process. These are most reliable than the active heat sinks; and, for efficient operation of passive heat sinks, it is recommended to maintain continuous air flow across their fins.
How to find the volume of a heat sink?
The volume of the Heat sink can be determined by dividing the volumetric thermal resistance by the required thermal resistance. The range of volumetric thermal resistance is as follows in the table shown below.
What is a folded fin heat sink?
These folded-fin heat sinks have large surface area,and possess folded heat sink material, and hence, they have very-high performance and very-high heat-flux density. In these sinks,air is directed to flow directly into heat sinks through some kind of duct.

I browsed the existing threads and there are posts out there about heatsinks and trying to cool the atty for the sake of cooling it but there aren't any that I could find about cooling them for better smoke production.

Lots of cold vapor? Is that what you're shooting for? Sounds like you need a triple coil 1.5ohm carto run on a 3.7V battery. That'll give you even more cold vapor than a dual coil on a 3.7V battery.
Malduk Super Member Verified Member ECF Veteran
There are rebuildables with longer and with shorter vapor path; those with longer path typically deliver colder vape, and less flavor. Basically, cooling equals condensation and flavor loss. At least in my experience.

I should get a variable volt or at least an SVR or EVO so I can do the 4-5V vaping @ 3.5 ohm.
sailorman Vaping Master ECF Veteran
The biggest advantage to using higher voltage/ohms is with a variable voltage. With a higher voltage/ohm, each .1V increment changes the Watts by a smaller increment than it would if you used a lower voltage/resistance.
motelgrim Senior Member ECF Veteran
Good information sailorman, thanks. I'm pretty much sold on variable/selectable voltage. And I'm fairly certain the 3VO/eVO will be my next mod although the Lavatube has a certain appeal to it...thats another thread though.
