Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, and in particular to an electric defrosting structure for a water tray in a cold storage refrigeration system. Background Technology

[0002] In cold storage refrigeration applications, when the operating temperature of the cold storage is below 0℃, especially when the operating temperature of the low-temperature cold storage is below -18℃, water vapor in the air inside the cold storage will freeze and frost on the surface of the cold evaporator fins and in the drip tray. The lower the temperature, the more important the frost formation. Frost formation will cause a serious decrease in the heat exchange efficiency of the evaporator, a decrease in the evaporation temperature, a decrease in the cooling capacity, an increase in the power consumption of the compressor, and a decrease in the energy efficiency ratio. Therefore, it is necessary to defrost the drip tray inside the evaporator of the cold storage.

[0003] A search revealed that patent specification CN211625841U discloses an electric defrosting structure for a water tray, comprising a water tray body and a defrosting tube fixed to the water tray body. The outer bottom surface of the water tray body has a downward-opening groove for the defrosting tube to fit snugly into. Because the water tray body is made of metal, it has a high thermal conductivity, resulting in rapid heat conduction and shortening defrosting and de-icing time. Furthermore, embedding the defrosting tube into the groove of the water tray body increases the contact area between the tube and the body, thus enhancing the heat conduction area and further improving the defrosting effect. This reduces the usage time of the defrosting tube, achieving energy savings. Moreover, it consumes relatively low power, avoids damaging the paint layer on the surface of the water tray body, and extends its service life.

[0004] The existing electric defrosting structure for the drip tray of a cold storage refrigeration system has been found to have shortcomings during use. It only has one heating element, and when this element malfunctions, it cannot defrost the drip tray in a timely manner, thus affecting the normal operation of the cold storage evaporator. Furthermore, the defrosting effect is not ideal. Therefore, it is necessary to optimize and improve the existing electric defrosting structure for the drip tray of a cold storage refrigeration system. Summary of the Invention

[0005] The purpose of this utility model is to overcome the above-mentioned problems existing in the traditional technology and to provide an electric defrosting structure for the water receiving tray of a cold storage refrigeration system.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: An electric defrosting structure for a water receiving tray in a cold storage refrigeration system includes a water receiving tray, a first electric defrosting component, a second electric defrosting component, a first support plate, a second support plate, support rings, and a drain pipe. The water receiving tray is a rectangular tray with an open top. The first and second electric defrosting components are symmetrically installed on the two side plates of the water receiving tray. The first and second support plates are installed around the periphery of the first and second electric defrosting components. Several support rings are installed between the lower side of the first and second support plates and the inner side of the bottom plate of the water receiving tray.

A second heat-conducting tube is sleeved on the outside of the second serpentine electric heating tube. The first heat pipe and the second heat pipe are symmetrically and alternately distributed.

[0008] Furthermore, in the above-mentioned electric defrosting structure for the water tray of the cold storage refrigeration system, there is a clearance area between the first support plate and the second support plate that matches the shape of the first heat-conducting pipe and the second heat-conducting pipe, and the connection between the first support plate and the second support plate and the first heat-conducting pipe and the second heat-conducting pipe is filled with low-temperature resistant sealant.

[0010] Furthermore, in the above-mentioned electric defrosting structure for the water tray of the cold storage refrigeration system, the drain pipe is an elbow pipe, the water inlet of the drain pipe is located above the first support plate / second support plate, and the water outlet of the drain pipe is vertically downward.
