What is the refrigeration principle of the multifunctional car and home dual-purpose thermoelectric cooler?The
multifunctional car and home dual-purpose thermoelectric cooler is a refrigeration equipment based on the principle of thermoelectric effect. It utilizes the special properties of thermoelectric modules (TEC) to achieve cooling effects through current and heat conduction. The following is a detailed introduction to the cooling principle of this refrigerator:
First of all, the core component of the multifunctional car and home dual-purpose thermoelectric cooler is the thermoelectric module (TEC). A thermoelectric module is a semiconductor device that utilizes the thermoelectric effect. It is composed of two different types of semiconductor materials, usually bismuth selenide (Bi2Te3) and bismuth selenide (Bi2Te3) sheet components. When an electric current passes through a thermoelectric module, a temperature difference is generated between the two semiconductor materials, causing the thermoelectric effect.
Secondly, according to the principle of thermoelectric effect, when current passes through the thermoelectric module, it will cause a temperature difference in the materials on both sides. One side gets colder and the other gets hotter. This is because inside the material, the energy carried by the current is absorbed in one direction (cold side) and released in the other direction (hot side). This temperature difference effect is called the "Penger effect".
Then, the multifunctional car and home dual-purpose thermoelectric cooler utilizes the characteristics of the Penel effect to achieve cooling. Typically, there is a heat sink and a cooler inside the refrigerator, with the thermoelectric module embedded between them. When electric current passes through the thermoelectric module, one side of the thermoelectric module absorbs heat and makes it very cold. This side is called the cold side. The other side releases heat, making it very hot. This side is called the hot side.
Then, the cold side removes the heat through conduction and convection, thereby lowering the temperature inside the refrigerator. At the same time, the heat on the hot side will be absorbed by the heat sink and dissipated to the external environment through the heat sink to maintain the operating temperature of the thermoelectric module.
How portable is the multifunctional car and home dual-purpose thermoelectric cooler?Multifunctional car and home dual-purpose thermoelectric coolers are usually designed very well in terms of portability to meet users’ carrying needs in different scenarios. The following is a detailed introduction to the portability of this cooler:
Size and weight: Multifunctional car and home dual-purpose thermoelectric coolers are usually designed to be compact and lightweight for users to carry. They are usually sized well enough to fit easily in the trunk of a vehicle, camper or outdoor gear bag. At the same time, the weight is relatively light, making it easy for users to carry and move.
Handle or handle design: In order to increase the convenience of carrying, refrigerators are usually designed with handles or handles that users can easily lift and carry. This design makes it more convenient for users to move the refrigerator without the need for additional tools or auxiliary equipment.
Wheel design: Some models of refrigerators are also equipped with wheels, so that users can pull it like a drag box without having to carry it hard. This design is especially suitable for long-term movement or use on uneven terrain, improving the convenience and comfort of transportation.
Compact appearance design: Refrigerators usually adopt a simple and streamlined appearance design to minimize volume and space occupation. This makes it easier for users to place the cooler in a vehicle, campsite, or indoor space without taking up too much space.
Power supply flexibility: In order to increase the flexibility of portability, multifunctional car and home dual-purpose thermoelectric coolers usually support multiple power supply methods, including vehicle power supply, household power supply, solar cells and backup batteries.
