Heat Dissipation Method of Thermal Shock Test Chamber Refrigeration Unit
Generally speaking, thermal shock test chamber is divided into two refrigeration methods: air-cooled and water-cooled. The accuracy of the test results not only depends on the excellent process quality of the equipment itself, but also is closely related to the cooling efficiency of the refrigeration unit. So what factors affect the heat dissipation efficiency?
In short, the air-cooled type has the greatest impact on its heat dissipation efficiency or environmental factors. For water-cooled refrigeration units, the key factor is the water tower configured as a fixed equipment, the following is the method of improving the heat dissipation efficiency of different cooling methods.
Firstly, air-cooled thermal shock test chamber：
Reason: Because the heat dissipation of the air-cooled refrigeration unit mainly relies on the electronic fan to dissipate a large amount of heat through the fin. If the environment is very dusty, the equipment is affected by the wind, a lot of dust will adhere to the fan and fins. Although less dust does not have any effect on the air-cooled refrigeration unit, when the dust on the fins continues to increase, it will directly affect the heat dissipation effect of the air-cooled refrigeration unit, resulting in poor heat dissipation effect and the corresponding cooling capacity.
1, The user should provide a relatively clean use environment for the air-cooled refrigeration unit (smooth ventilation is the best), and try to stay away from the harm of all kinds of dust. This will extend the frequency of inefficient operation of air-cooled refrigeration units because there is more dust in the environment, and give the unit equipment a safe and stable operation environment.
2, Keep the equipment clean and tidy, and clean the fins regularly. Can be washed with wind and tap water, if the environment is harsh, the dust impurities on the fins are more oil, then rinse with tap water first, and then spray on cleaning dust, after 10 minutes or so, and then repeatedly rinse with tap water. After using the air-cooled refrigeration unit for a period of time, it is necessary to carry out a comprehensive cleaning for the environment and the machinery and equipment.
Secondly, water-cooled thermal shock test chamber：
Reason: Since most of the water tower is installed outside, it needs to withstand strong light radiation, higher temperature, and fast water evaporation, which is easy to cause insufficient water flow in the cooling water circulation, and finally cause poor cooling effect and even high pressure alarm.
1, Timely water supply.
2, Check whether the water supply valve is abnormal.
3, Check the running status of the water tower, if abnormal, it needs to be adjusted to normal state in time.
4, Clean the pipeline filter.
5, Keep the water source clean.
The main policy to improve the heat dissipation efficiency of the air-cooled thermal shock test chamber is to place the chiller outdoors, avoid direct sunlight as far as possible, and make a protective shed for the equipment if conditions exist. If it must be placed indoors, it is better to put it next to the window to maintain good ventilation, or install an air pipe to draw hot air to the outside.
