Description

Technical Field

[0001] The present application relates to the technical field of thermal leakage testing, for example, to a device for detecting thermal leakage of a door seal. Background Art

[0002] As a traditional household appliance, refrigerators have a growing number of households, and their electricity consumption accounts for about 10% of the total electricity consumption of the country. Energy saving and environmental protection are the future development direction of refrigerators. The power consumption of refrigerators is mainly used to produce cold air to offset the heat leakage load during its stable operation. The size of the heat leakage load is directly related to the insulation performance of the refrigerator.

[0003] The heat leakage of a refrigerator mainly includes heat leakage from the cabinet, heat leakage from the door and heat leakage from the door seal. The heat leakage from the door seal accounts for about 15% of the total heat leakage of the refrigerator. However, there is currently no effective measurement method to detect the heat leakage from the door seal. This part of the heat can only be represented by empirical values ​​or correction coefficients.

[0075] In some optional embodiments, one of the multiple side panels 130 is provided with a wiring harness hole 1301 , which penetrates the side panel 130 , and the wiring harness of the heating device 200 , the wiring harness of the temperature sensor and the wiring harness of the heat flux density sensor can pass through the wiring harness hole 1301 .

[0076] Optionally, the fixing plate is provided with a wiring harness hole 1301, for example, the first fixing plate 131 is provided with a wiring harness hole 1301, and the wiring harness hole 1301 passes through the first fixing plate 131, or, the second fixing plate 132 is provided with a wiring harness hole 1301, and the wiring harness hole 1301 passes through the second fixing plate 132, or, the third fixing plate 133 is provided with a wiring harness hole 1301, and the wiring harness hole 1301 passes through the third fixing plate 133.

[0077] Furthermore, the device for detecting thermal leakage of door seals further comprises a seal, which is arranged between the inner wall of the harness hole 1301 and the outer wall of the harness, wherein the harness comprises the harness of the heating device 200 and / or the harness of the temperature sensor and / or the harness of the heat flux density sensor. In this way, the seal can reduce the heat loss at the harness hole 1301 and improve the accuracy of the device for detecting thermal leakage of door seals.
