Sorry, I don't understand your question. Do you intend to get a list of technical cooling devices? Or to get a list of which techniques are used for cooling?

Types of cooling devices and techniques are broadly categorized into

active cooling (using mechanical or electrical power) and passive cooling (using natural processes).

Active cooling

Active cooling devices use an external power source to move heat away from a system.

1. Vapor-compression refrigeration

This is the most common cooling technology, used in air conditioners and refrigerators.

• How it works: A refrigerant fluid is sent through a closed cycle of compression, condensation, expansion, and evaporation. As it evaporates, it absorbs heat, which is then released elsewhere when the fluid is condensed back into a liquid.
• Examples: Central air conditioners, window units, and refrigerators.

2. Evaporative cooling

This method cools air by pulling it through moist pads, reducing its temperature and increasing its humidity.

• How it works: The process mimics the body's natural cooling mechanism. When water evaporates, it draws heat energy from the air around it.
• Examples: "Swamp coolers" or portable air coolers, which are most effective in hot, dry climates.

3. Thermoelectric cooling

Based on the Peltier effect, this solid-state technology provides cooling without a compressor.

• How it works: An electric current is passed through a junction of two dissimilar semiconductors, causing heat to be absorbed on one side and released on the other.
• Examples: Small refrigerators, CPU coolers, and temperature control for sensitive electronic components.

4. Absorption refrigeration

Similar to vapor-compression, this technology uses a heat source instead of a mechanical compressor to drive the cooling cycle.

• How it works: A thermal "compressor" uses heat to drive the evaporation and condensation of a refrigerant, which is dissolved into and out of an absorbent material.
• Examples: Gas-powered or waste-heat-powered refrigerators and large-scale industrial systems.

5. Forced convection

A simple and cost-effective active cooling technique.

• How it works: Fans or blowers are used to force air across heat-generating components to carry heat away via convection.
• Examples: Standard air-cooled CPU and GPU fans in a computer.

6. Liquid cooling

This method uses a fluid instead of air to transfer heat, offering superior performance for high thermal loads.

• How it works: Coolant is circulated through a closed-loop system, which consists of a water block on the heat source, a pump, and a radiator. The liquid absorbs heat and carries it away to the radiator to be dissipated.
• Examples: High-performance computers, gaming consoles, and industrial equipment.

Passive cooling

Passive cooling devices rely on natural thermodynamic processes to manage temperature without using an external energy source.

1. Heat sinks and thermal pads

These are commonly used in electronics to move heat away from a component.

• How they work: Heat sinks are typically made of a conductive material with fins to increase surface area. They absorb heat from a component and naturally dissipate it into the surrounding air through convection. Thermal pads fill microscopic gaps between a heat source and a heat sink, enhancing thermal conduction.
• Examples: Used in nearly all electronics, from CPUs to power regulators.

2. Radiant cooling

This technology cools surfaces, which then absorb heat from warmer objects in the environment through thermal radiation.

• How it works: Cool water is pumped through panels in ceilings, walls, or floors. These surfaces then act as "heat sinks," absorbing radiant heat from people and objects in the room. This creates a comfortable environment without the drafts of forced-air systems.
• Examples: Modern architectural designs for energy-efficient homes and buildings.

3. Thermal mass

This technique uses a material's ability to absorb and store a large amount of heat to regulate temperature.

• How it works: Buildings and components constructed with high-thermal-mass materials like concrete or stone absorb heat during the day and release it slowly at night, stabilizing indoor temperatures.
• Examples: Modern buildings designed for passive climate control.

4. Natural ventilation and shading

These strategies use natural airflow and sun control to manage indoor temperatures.

• How it works: Building design can use natural airflow (convection) through windows and vents to cool a space. Shading elements like awnings or window films prevent solar radiation from entering and heating a building.
• Examples: Designing homes with windows and vents positioned to maximize cross-breezes.
