Description

Technical Field

[0001] This utility model relates to the technical field of air coolers, and in particular to a paint spraying device for air cooler housings. Background Technology

[0002] An air cooler is a heat exchanger that uses low-temperature water to cool high-temperature air. Traditional air coolers use external finned heat exchangers, where air flows along the finned side (shell side) and low-temperature water flows along the inner side of the heat exchange tubes (tube side). The low-temperature water inside the tubes exchanges heat with the high-temperature air outside the tubes through the tube walls and fins.

[0003] Existing air cooler housing paint spraying devices, such as the high and low voltage distribution cabinet housing paint spraying device disclosed in utility model patent application number 202421803358.3, mainly include a support platform, a connecting frame fixedly connected to the top of the support platform, a spraying plate fixedly connected inside the connecting frame, and a long box fixedly connected to the top of the support platform. The long box is equipped with a moving mechanism, and a limit mechanism is provided on the front of the moving mechanism. In use, the distribution cabinet housing to be sprayed is first placed inside the support platform, and then the handwheel is turned to drive the threaded rod to rotate. Since the threaded rod and the top of the support platform are threadedly connected, the rotational motion of the threaded rod is converted into the linear motion of the pressure plate. The pressure plate serves to press and limit the distribution cabinet housing.

[0004] However, air cooler housings often contain complex curved surfaces such as heat dissipation fins and pipe interfaces. Existing spraying equipment has blind spots and poor spraying effect. Moreover, most existing spraying equipment is open spraying, which can easily lead to paint mist diffusion, polluting the environment and wasting paint. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an air cooler shell paint spraying device that not only enhances the sealing effect of the device and prevents the diffusion of paint mist, but also allows the paint to flow back, saving paint, and can spray the shell from multiple angles to ensure uniform spraying on all surfaces of the shell.

[0006] This utility model discloses a paint spraying device for an air cooler housing, comprising a moving mechanism; it also includes a supporting mechanism, a sealing mechanism, a spraying mechanism, a conveying mechanism, and a storage mechanism. The supporting mechanism is mounted on the moving mechanism to support the housing, the sealing mechanism is mounted on the moving mechanism to prevent paint mist diffusion, the spraying mechanism is mounted on the sealing mechanism to spray the housing, the conveying mechanism is mounted on the spraying mechanism to convey the paint, and the storage mechanism is mounted on the conveying mechanism to store the paint.
