Abstract

The invention provides a thermal load calibration device for heat leakage performance experiment, comprising: a heating system, the heating system includes a heating element, and the heating element is heated to provide heat energy to the inside of the device after being energized; a temperature control system, the temperature control system is electrically connected with the heating system, The heating system controls the heating system to shut down when the temperature reaches the set value, and stops the heating process; the heat dissipation system, the heat dissipation system includes an upper heat dissipation device, a middle heat dissipation device and a lower heat dissipation device connected to each other, the heating element is arranged inside the upper heat dissipation device, and the middle heat dissipation device The upper surface of the device is bonded and connected with the lower surface of the upper heat sink, and the lower heat sink is fixed on the bottom of the middle heat sink. The device can set the target temperature arbitrarily, and provide a heat source with adjustable power and temperature; the heat dissipation is rapid, and the heating space is more uniform; the device is simple in structure, small and convenient, easy to operate, high in test accuracy, flexible in application, and suitable for specific internal spaces. Experimental detection of heat leakage performance.

Description

technical field [0001] The invention specifically relates to a heat load calibration device for a heat leakage performance experiment, which is used to simulate heating amount in heat insulation or heat leakage experiments of refrigerators and environmental comfort. Background technique [0002] The energy efficiency level (energy saving level) of a refrigerator depends on the efficiency of the refrigeration system and the insulation / insulation performance of the cabinet and door seals. Usually, heat leakage performance experiments, that is, insulation performance experiments of refrigerators, are required in the design and development of refrigerators. [0003] In people's daily life and work, the temperature and air conditioning of indoor rooms have an important impact on the comfort of the human body. When designing air-conditioning products, comfort-related tests must be carried out to test the comfort used, usually in the laboratory to simulate buildings. The actual he...
