Problems solved by technology
[0002] At present, the cooling method of many products such as converters and motors is water-cooled. When testing such products, in order to simulate their harsh operating environment to the greatest extent, the tested products need to be tested at a certain constant cooling water temperature. At present The water cooling system used in the laboratory has a simple structure and no cooling water temperature control function, which cannot meet the test requirements of products with water temperature requirements, which greatly restricts the verification of the performance of the tested products

Embodiment Construction
[0041] The present invention will be further described below in conjunction with accompanying drawing.
[0042] figure 1 A block diagram of the coolant supply device 1 in the first embodiment is shown. The coolant supply device 1 includes a first circuit 10, a second circuit 20, a heat exchanger 30 and a control unit (not shown). The first loop 10 is connected to the product under test. The first loop 10 removes the heat from the product under test. The first loop 10 and the second loop 20 exchange heat through the heat exchanger 30, and the second loop 20 takes out the heat in the first loop 10. The control unit makes the temperature of the cooling liquid output from the first circuit 10 reach a preset value by controlling the flow rate of the cooling liquid in the second circuit 20 .
[0043] The first circuit 10 includes a first pipeline 101 , a water tank 105 , a first temperature sensor 103 , a second temperature sensor 102 and a pump 104 . The first line 101 is prov...

The invention relates to a coolant supply apparatus and a method for controlling the temperature of a coolant. The coolant supply apparatus includes: a first loop, a second loop, a heat exchanger and a control unit. The fluid in a first pipeline and a second pipeline exchange heat in the heat exchanger. The control unit, based on the temperature values measured by a first temperature sensor and a second temperature sensor in the first loop, regulates the opening level of a first valve and a second valve in the second loop, such that the temperature of the coolant at an outlet of the first loop is equal to a preset value. The method herein is intended for the control unit. The coolant supply apparatus can conduct automatic regulating to realize automatic control of the temperature of the output coolant.
