Spraying protection device for evaporator

Abstract

The invention discloses a spraying protection device for an evaporator. The spraying protection device for the evaporator comprises a frame and a plurality of shielding assemblies, wherein the frame is formed by encircling of side plates, and the inner portion of the frame is used for holding the end portion of the evaporator; and the shielding assemblies comprise baffles and connecting plates, the connecting plates are connected with the side plates in a sliding mode, the baffles are located inside the frame and rotatably connected with the connecting plates, and the baffles can be connectedwith the inside and outside side surfaces of the end portion of the evaporator in the plane direction perpendicular to the end portion of the evaporator correspondingly in a butting mode. The sprayingprotection device can be adjusted according to the shape of the evaporator and is closely attached to the inside and outside side surfaces of the evaporator, effective protection can be achieved, andit is guaranteed that no spraying paint is sprayed to reach a fin of the evaporator during the spraying process; the structure is simple, adjustment is achieved by sliding or rotating of the shielding assemblies, the operation is simple; and the spraying protection device can be recycled, environmental protection and saving are achieved, and the cost is reduced.

Description

technical field [0001] The invention relates to a protection device, in particular to a spray protection device for an evaporator. Background technique [0002] When the air-conditioning evaporator is sprayed and other processes are carried out, the spraying process is not well controlled during the painting process, and it is easy to cause the spray paint to be sprayed on the evaporator fins. On the one hand, the heat exchange effect of the evaporator is poor, and on the other hand, the evaporator is damaged. It is not beautiful, the user experience is reduced, and long-term painting production will cause a decrease in production efficiency. [0003] The existing spray protection measures are wrapped with rubber felt. The felt is a soft structure, which does not fit closely with the evaporator and cannot be effectively protected. Moreover, with the increase in the number of uses, it is easy to cause problems such as rubber felt breakage; or use aluminum foil The way of adh...

[0002] When the air-conditioning evaporator is sprayed and other processes are carried out, the spraying process is not well controlled during the painting process, and it is easy to cause the spray paint to be sprayed on the evaporator fins. On the one hand, the heat exchange effect of the evaporator is poor, and on the other hand, the evaporator is damaged. It is not beautiful, the user experience is reduced, and the long-term painting production will cause the production efficiency to drop

[0003] The existing spray protection measures are wrapped with rubber felt. The felt is a soft structure, which does not fit closely with the evaporator and cannot be effectively protected. Moreover, with the increase in the number of uses, it is easy to cause problems such as rubber felt breakage; or use aluminum foil The way of tape, but it will cause a lot of waste of tape, which is not conducive to environmental protection
