There are roughly 3 types of car refrigerators. The performance of the 3 types of refrigerators is quite different.
The first category is a relatively early product, so it may not be suitable for refrigerators, because it does not have the cooling function, only the insulation function, when used, the items to be refrigerated must be frozen in the refrigerator and put into the incubator with ice packs. Then put it in an ice pack so that you can keep it frozen for a short time.
The advantage of this type of refrigerator is that it does not consume electricity. It is necessary to know that the electricity on the car is exchanged for oil and the price is relatively low. The disadvantage is that it cannot be insulated for a long time and the space is small.
The second type is the semiconductor car refrigerator. Its principle is to rely on electronic chip cooling, the use of special semiconductor materials constitute the PN junction, the formation of thermocouple pairs, resulting in the Peltier effect, that is, a new type of refrigeration through DC cooling. The refrigeration temperature range is 5 to 65 degrees. The refrigerator in the car can not only cool, but also heat and keep warm. It has the advantage that the conventional refrigerator is incomparable. The main advantages are: environmental protection, no pollution, small size, low cost, no vibration and noise during work. long life. The disadvantage is that the cooling efficiency is not high and the capacity is small.
The third category is the compressor on-board refrigerator. The compressor is the traditional technology of the traditional refrigerator. The cooling temperature is low, -18 degrees and 10 degrees. The high cooling efficiency and large volume are the main directions for the development of future car refrigerators. The disadvantages are heavy weight, relatively high power consumption, and high prices. Compressors Automobile refrigerator compressors are mainly produced in Germany and Japan. The domestic high-end compressors and compressors for automobiles and cars are mainly made in Germany and have good quality.
From the above three categories, each category has different advantages and disadvantages. Users should purchase according to their own actual needs to avoid waste.
There are three types, one is electronic and the other is compressor. Both are driven by the 12V power supply of car cigarette lighter. The refrigerator storage box is located in the rear seat center armrest.
There is another car refrigerator, in fact it is just a low-temperature storage box, located in the glove box before the co-pilot. It does not have a separate compressor. Its air conditioning comes from the air conditioning system. This so-called car refrigerator is generally used on medium-low or low-grade cars. The capacity of the car refrigerator is very small, generally only a few bottles of mineral water can be placed. The position of the car refrigerator is generally in the center console, the front passenger storage box, the rear center armrest or the trunk. This is the case in most car refrigerators on the market. Unlike ordinary domestic refrigerators, it does not use the principle of mechanical compression of compressors. Instead, it adopts the principle of electronic (semiconductor) refrigeration, although noise and pollution are not generated, and the power supply is Special on-board power supply, but the cooling effect and compressor cooling cannot be compared. Car owners generally need to put food in the household refrigerator to cool down before putting food and drinks into the car refrigerator.

The Ming Sword is renowned for its excellent craftsmanship and superior cutting ability. It is often praised for its balance and versatility, making it suitable for both slashing and thrusting techniques. The blade is typically made of high-quality carbon steel, which provides durability and sharpness.
The hilt of the Ming Sword is usually made of hardwood, wrapped in leather or silk for a comfortable grip. It features a circular or rectangular guard, known as a tsuba, to protect the hand during combat. The pommel, often adorned with decorative elements, adds balance to the sword.
In addition to its practical use in combat, the Ming Sword is also considered a work of art. Its elegant design and intricate engravings make it a prized possession
