Problems solved by technology

[0003] At present, most of the heat in the three-compartment thermal shock test chamber is to neutralize the cold air in the refrigeration device and the hot air in the heating device to cool down. Every time a thermal shock test is performed, the air needs to be refrigerated and conditioned again. Therefore, how to reuse the cold air of the refrigeration box and the hot air of the heating box has become a technical problem that needs to be solved in the field of testing machines

Embodiment 1

[0034] Embodiment 1: When the product needs to be subjected to thermal shock test, the test product is placed in the test box 2, the controller (not shown in the figure) closes the first control valve 101, and the controller (not shown in the figure) The sixth control valve 106 of the three second energy storage tanks 9 is closed, the ninth control valve 109 is closed, the fifth control valve 105 is opened, and the second cylinder 66 controls the closing of the second closing door 65 so that the heating box 4 and the test The tank 2 is isolated, and the heating push pump 12 heats the second exchange line 11 and circulates the exchange liquid in the second exchange line 11 on the second exchange loop, and transfers the heat when passing through the second heat exchanger 10 Conduction in the heating box 4, the temperature of the heating box 4 increases, when the temperature sensor (not shown in the figure) in the heating box 4 detects that the temperature of the heating box 4 rea...

Embodiment 2

[0035] Embodiment 2: When it is necessary to recover the heat energy after the thermal shock test of the product, the controller (not shown in the figure) controls to open the first control valve 101, the third control valve 103, the fifth control valve 105, and the sixth control valve. Valve 106, close the second control valve 102, the fourth control valve 104, the seventh control valve 107, and the ninth control valve 109, start the second exhaust fan 64, start the heating push pump 12 and the cooling push pump 8 to increase the liquid Flow rate function, the heat in the heating tank 4 will pass through the second exchange pipeline 11, the branch exchange pipeline 13, and the first exchange pipeline 7 through the exchange liquid to conduct heat in the first energy storage tank 5 and the second energy storage tank 9, when the controller (not shown in the figure) detects that the temperature in all the energy storage tanks no longer rises, the heating push pump 12 and the refri...

Embodiment 3

[0036] Embodiment 3: When it is necessary to recover the heat energy after the thermal shock test of the product, there is another heat energy recovery method, the controller (not shown in the figure) controls to open the first control valve 101, the fifth control valve 105, and close The second control valve 102, the third control valve 103, the fourth control valve 104, the sixth control valve 106, the seventh control valve 107, and the ninth control valve 109 start the second exhaust fan 64 and open one of the second storage tanks. The sixth control valve 106 of the energy tank 9 activates the function of increasing the liquid flow rate of the heating push pump 12 and the cooling push pump 8, and the heat in the heating tank 4 will pass through the second exchange pipeline 11 and the branch exchange pipeline through the exchange liquid. 13. The first exchange pipeline 7 conducts heat to the second energy storage tank 9 that opens the sixth control valve 106. When the control...

Abstract

The invention relates to a thermal shock tester, and belongs to the technical field of impact test. The tester comprises a casing, a controller, a test box, a cooling box, a heating box, a first energy storage assembly and a second energy storage assembly. The test box is communicated with the heating box and the cooling box, the first energy storage assembly exchanges heat with the cooling box, the second energy storage assembly exchanges heat with the heating box, and the first and second energy storage assemblies are communicated. The first energy storage assembly is arranged to exchange cold air in the cooling box with heat in the first energy storage assembly, so that the temperature of an energy storage material in the first energy storage assembly is reduced, equivalently, the coldair is stored; and the second energy storage assembly is arranged to exchange heat of the heating box with heat in the second heat storage assembly, the temperature of an energy storage material of the second energy storage assembly is increased, and equivalently, hot air is stored.
