Cooling device

Abstract

The invention provides a cooling device, in particular to a temperature-controllable multipurpose cooling device used for testing and applied to cooling oil / cooling liquid and cooling water. The cooling device comprises a primary side loop, a second side loop and an intermediate loop. The primary side loop is connected with an external circulating device, circulating water with higher temperature is guided into the external circulating device, and circulating water with lower temperature is introduced. The secondary side loop is provided with a tested device and is used for cooling the tested device. The intermediate loop is connected with the primary side loop and the secondary side loop, the intermediate loop exchanges heat with the secondary side loop and absorbs heat of the secondary side loop, and meanwhile, the intermediate loop exchanges heat with the primary side loop and releases heat to the primary side loop. The circulating liquid in the secondary side loop adopts a mode of combining circulating water and circulating oil. According to the invention, through the cooperation of cooling water and cooling oil, the application temperature range is wide, and a simulation test is carried out on the tested device by simulating severe conditions.

Description

Technical field[0001]The present invention relates to a cooling device, in particular a multi-purpose cooling device shared by a controlled temperature, test, cooling oil / coolant, cooling water.Background technique[0002]In order to maximize the harsh conditions of the site, some products such as water-cooling converters, motors, etc. need to be tested at a certain cooling temperature. The general method of the currently employed cooling device is water-cooled, and the human manual adjustment heat exchange The external circulating water flow of the unit changes the heat of the external circulating water, by adjusting, the heat taken away by the external circulating water is approximately equal to the amount of heat of the subject, thereby ensuring the temperature of the sample to cool the water temperature.[0003]Since the current water-cooled device needs to be manually controlled, the water temperature fluctuation is large, the accuracy is not high, and the accuracy of the test re...

Problems solved by technology

[0003] As the current water-cooling device needs to be manually controlled and adjusted, the water temperature fluctuates greatly and the accuracy is not high, which seriously affects the accuracy of the test results, and the operator needs to work at the test site for a long time, with harsh environment and heavy workload

In addition, if the current water-cooling system uses a large flow valve, it cannot be applied to the test requirements of products with a small calorific value due to precision reasons; and if a valve with a small flow rate is used, it is not suitable for product tests with a large calorific value. demand, resulting in low versatility
