Description

Technical Field

[0001] The utility model relates to the technical field of dustproof structures, in particular to a dustproof structure for an air-conditioning evaporator. Background Art

[0002] The evaporator is a medium that absorbs heat to vaporize and absorb external heat. As a device for heat exchange between refrigerant and low-temperature heat source in the refrigeration system, the evaporator is also one of the main heat exchange equipment in the refrigeration device. In the evaporator, the refrigerant liquid vaporizes at low pressure and low temperature to absorb the heat of the cooled medium, becoming a refrigerant dry saturated gas or superheated base vapor at low temperature and low pressure, thereby generating and outputting cooling capacity in the refrigeration system.

[0003] In the prior art, a Chinese patent with the announcement number CN217178945U proposes an air-conditioning evaporator packaging dust-proof structure, which cooperates with the functions of a rotating rod, a fixed rod and a clamping block to position the mounting frame, and after the dust-proof net has been used for a period of time, it is convenient to remove the mounting frame and the dust-proof net from the evaporator body, thereby achieving the effect of easy disassembly and assembly, which is relatively practical and suitable for wide promotion and use. However, in actual application, the above-mentioned air-conditioning evaporator dust-proof structure only has a dust-proof net installed on one side of the air-conditioning evaporator after wrapping the air-conditioning evaporator, which greatly reduces the air circulation in the inner cavity of the dust-proof structure, affects the heat dissipation of the air-conditioning evaporator, and is prone to problems affecting the use effect of the air-conditioning evaporator. Therefore, we disclose an air-conditioning evaporator dust-proof structure. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a dust-proof structure for an air-conditioning evaporator, so as to solve the problem that the dust-proof structure affects the use effect of the air-conditioning evaporator.

One end of the fixed plate is fixedly connected to the evaporator body, and the outer wall of the evaporator body is movably sleeved with a dust-proof mesh plate, and the dust-proof mesh plate is slidably connected between the four limit rods.

[0006] Preferably, the side of the limit rod is L-shaped, the limit rod is adapted to the dustproof mesh plate, the side of the dustproof mesh plate is mouth-shaped, preferably, the other end of the dustproof mesh plate is fixedly connected to a connecting plate, and the middle of the connecting plate is fixedly connected to a T-shaped handle.

[0010] Preferably, the top end of the rotating groove is fixedly connected to a limit spring, the bottom end of the limit spring is fixedly connected to an extrusion plate, and the extrusion plate is fitted with the limit block.

[0011] The dustproof screen plate is fixed to one end of the fixing plate to ensure the normal operation of the evaporator body, and the evaporator body is easy to load and unload, making the dustproof structure easy to use. The evaporator body is dust-proofed by the dustproof screen plate, and the position of the dustproof screen plate is limited by the limit rod, so that the dustproof screen plate is not easy to shake and damage the evaporator body when the evaporator body is dust-proof.
