The high and low temperature coolant tester is a widely used equipment for the performance testing of materials, components and products, which can accurately test samples in different temperature environments. However, many people do not understand how the device is cooled and the difference between them. In this paper, the two main cooling methods of high and low temperature coolant tester - air cooling and water cooling are introduced in detail, and the main differences between them are analyzed.

First, air cooling cooling method

1. Working principle: Air-cooled cooling method mainly inhales the external air through the built-in fan of the device, takes away the heat of the device through the radiator, and then exhauts the hot air.

2, advantages: The structure of the air-cooled cooling method is relatively simple, easy to maintain, and the cost is low. At the same time, since no additional water source is required, it is more flexible in use.

3, disadvantages: the heat dissipation efficiency of air-cooled cooling method is relatively low, for large or high-power equipment, may not be able to meet its heat dissipation needs. In addition, the air-cooled cooling method is also susceptible to the impact of the ambient temperature, when the ambient temperature is high, the heat dissipation effect will be further reduced.

Two, water cooling cooling method

1, the working principle: The water cooling cooling method mainly introduces the coolant into the equipment through the circulating water system, absorbs the heat generated by the equipment, and then discharge the hot coolant to the external radiator for heat dissipation.

2, advantages: The water-cooled cooling method has high heat dissipation efficiency, which can meet the heat dissipation needs of large or high-power equipment. At the same time, because the specific heat capacity of water is larger, its heat dissipation effect is more stable and not easily affected by the ambient temperature.

3. Disadvantages: The structure of water-cooled cooling method is relatively complex, requiring additional water sources and radiators, so it is relatively high in cost and maintenance. In addition, if improper use or coolant leakage, it may also cause damage to the equipment.

Third, the difference between air cooling and water cooling

1, heat dissipation efficiency: the heat dissipation efficiency of water-cooled cooling method is significantly higher than that of air-cooled cooling method, which can meet the heat dissipation requirements of higher power equipment.

2, cost and maintenance: the cost and maintenance of air-cooled cooling method is relatively low, while water-cooled cooling method requires higher cost and maintenance investment.

3, the use of flexibility: air cooling cooling mode does not require additional water and radiator, the use of more flexible; The water-cooled cooling method needs to consider the setting of the water source and the radiator.

4, environmental impact: the air-cooled cooling method is susceptible to the impact of the ambient temperature, while the water-cooled cooling method is relatively stable and not susceptible to the interference of the ambient temperature.
