Why can air-cooled car cooler and warmer make the temperature inside the box more uniform and stable?
The main reasons why air-cooled car cooler and warmer can make the temperature inside the box more uniform and stable include its working principle, design features and internal structure. These aspects are detailed below:
1. Uniformity of working principle: The air-cooled car cooler and warmer adopts the working principle of thermoelectric effect and fan circulation. When DC electricity is passed through a thermoelectric module, one side of the module absorbs heat while the other side expels hot air. Through the built-in fan, the air in the box is forced to circulate, so that the heat in the box can be evenly distributed, thereby achieving temperature uniformity.
2. Design of heat sink: Air-cooled car cooler and warmers are usually equipped with heat sinks. These heat sinks are located on the hot side of the thermoelectric module to increase the heat dissipation surface area. Through the design of the heat sink, the heat generated in the box can be dissipated more quickly, preventing local temperatures from being too high, thereby maintaining the uniformity of the temperature in the box.
3. The role of fan circulation: The built-in fan is not only used to discharge the heat in the box, but also promotes the circulation of air in the box. This circulation allows the air in the box to be fully mixed, thereby making the temperature more uniform. 
4. Advantages of design structure: Air-cooled car cooler and warmer usually have a compact design structure, and the space inside the box is fully utilized. This design structure makes the circulation effect of the fan more obvious, and can evenly flow the air through the thermoelectric module and heat sink, avoiding the problem of uneven temperature.
5. Temperature control system: Some advanced air-cooled car cooler and warmers are also equipped with a temperature control system, which can monitor the temperature inside the box in real time and adjust the working status of the thermoelectric module to maintain the temperature inside the box within the set range. 


How durable is an air-cooled car cooler and warmer?
The durability of an air-cooled car cooler and warmer depends on many factors, including its manufacturing quality, material selection, usage environment, and user maintenance. The durability of air-cooled car cooler and warmers will be discussed in detail below:
1. Manufacturing quality and material selection: The manufacturing quality and selected materials of an air-cooled car cooler and warmers are one of the important factors that affect its durability. High-quality manufacturing processes and high-quality materials ensure that the product is not prone to damage or failure during long-term use.
2. Durability of internal parts: The internal parts of the air-cooled car cooler and warmer include thermoelectric modules, fans, heat sinks, etc. The durability of these parts directly affects the service life of the entire product. High-quality parts can withstand long hours of work and are less prone to failure.
3. Influence of the use environment: The use environment also has a great impact on the durability of the air-cooled car cooler and warmer. For example, if it is often used in harsh environments, such as areas with high temperature, high humidity, and dust, or is subject to frequent vibrations, collisions, etc., the service life of the air conditioner may be shortened.
4. Importance of maintenance: Regular maintenance is essential to extend the service life of the air-cooled car cooler and warmer. This includes cleaning the heat sink, keeping vents clear, and regularly checking internal parts for abnormal wear or damage.
5. Frequency and method of use: The frequency and method of use of the air-cooled car cooler and warmer will also affect its durability. Frequent use and long-term continuous operation may accelerate the wear of parts, but proper use can reduce this wear and extend the service life of the product.
