Description

Technical Field

[0001] This utility model relates to the technical field of heat exchanger plastic support frames, and specifically to a heat exchanger plastic support frame that is easy to install. Background Technology

[0002] Plastic support frames for heat exchangers provide stability and safety, ensuring stable operation of the heat exchanger under various working conditions. A search revealed existing technology (publication number: CN202323496436.8) for a plate-fin heat exchanger with a protective structure. The document states that "this plate-fin heat exchanger with a protective structure, through the setting of a baffle structure, utilizes a back plate, top plate, and front plate to protect the fins. Simultaneously, the top plate and back plate are movably connected by connectors, and the front of the locking block has a slot for engaging with the locking rod, facilitating later maintenance of the fins or the interior of the heat exchanger." However, in this existing technology, the back plate, top plate, and front plate on the support frame, when supporting and protecting the side of the heat exchanger, can easily affect the airflow rate on the fin surface. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a heat exchanger plastic support frame that is easy to install is provided to solve the problem that the back plate, top plate, and front plate on the support frame can easily affect the airflow rate on the fin surface when supporting and protecting the side of the heat exchanger.

[0004] To achieve the above objectives, a heat exchanger plastic support frame that is easy to install is provided, comprising: a plastic support base and a plate heat exchanger, wherein the plate heat exchanger is snapped onto the upper end of the plastic support base via a side support plate.

[0005] An L-shaped limiting guard plate is inserted through the upper surface of the side support plate. The upper surface of the L-shaped limiting guard plate is fixed to the side support plate by fixing bolts. The L-shaped limiting guard plates are symmetrically distributed at the corners of the front shell of the plate heat exchanger. A vibration isolation base plate is movably connected to the inner side of the plastic bracket base through a connecting slider. A roller is installed on the lower end face of the connecting slider. The plate heat exchanger is placed on the upper surface of the vibration isolation base plate.

[0006] Furthermore, two sets of side support plates are symmetrically welded to the upper surface of the plastic bracket base; and the two sets of side support plates are distributed at the rear shell of the plate heat exchanger.

[0007] Furthermore, a top plate is fixed to the upper surface of the L-shaped limiting guard plate; and the top plate is attached to the upper surface of the side support plate, and a fixing hole is opened at the side end of the L-shaped limiting guard plate.

[0008] Furthermore, the front side of the plastic bracket base is inserted into the surface of the L-shaped limiting guard plate via an elastic insert plate, and the inner side of the side support plate is in contact with the plate heat exchanger via a sponge pad.

[0009] Furthermore, the plastic bracket base has a groove on its surface; and a connecting slider slides in the groove, and two sets of connecting sliders are provided on the lower surface of the vibration isolation base plate.

[0010] Furthermore, the front protruding end of the vibration isolation base plate is screwed to the plastic bracket base via a positioning stud, and a buffer rib is attached to the rear shell surface of the plate heat exchanger.

[0011] Furthermore, the rear side of the buffer rib is connected to the inner groove wall of the side support plate via a support spring; and the buffer rib is in the form of a vertical rectangular strip.

[0012] The beneficial effects of this utility model are as follows: the easy-to-install plastic support frame for heat exchangers utilizes an L-shaped limiting guard plate that is inserted downwards and fixed to the surface of the plate heat exchanger shell, allowing the plate heat exchanger to be snapped into place inside the plastic support frame. By moving the L-shaped limiting guard plate up and down, the plate heat exchanger on the support frame can be quickly installed or removed, shortening the inspection and maintenance time of the plate heat exchanger. At the same time, it avoids the support frame occupying the heat dissipation space of the heat exchanger fins. The plate heat exchanger on the plastic support frame is pulled out by the vibration isolation base plate that slides in the groove of the plastic support base, making it convenient and quick to remove the heat exchanger from the support frame and ensuring that the plate heat exchanger is moved smoothly into and out of the support frame surface.

The L-shaped limiting guard plates 2 are symmetrically distributed at the corners of the front shell of the plate heat exchanger 3. The inner side of the plastic bracket base 1 is movably connected to the vibration isolation base plate 4 by the connecting slider 41. A roller 43 is installed on the lower end of the connecting slider 41. The plate heat exchanger 3 is placed on the upper surface of the vibration isolation base plate 4.

[0020] When installing the plate heat exchanger 3, first fix the plastic bracket base 1 in a suitable location, then place the plate heat exchanger 3 on the surface of the previously moved vibration isolation base plate 4, push the vibration isolation base plate 4 into the groove of the plastic bracket base 1, and fix it with positioning studs 42. Move the plate heat exchanger 3 on the vibration isolation base plate 4 into the inner side of the plastic bracket base 1 and the side support plate 11, then move the L-shaped limiting guard plate 2 down so that the lower front side of the L-shaped limiting guard plate 2 is inserted into the elastic insert plate 14 of the plastic bracket base 1. After fixing the L-shaped limiting guard plate 2 to the side support plate 11 with fixing bolts 22, the installation of the plate heat exchanger 3 can be completed.

[0021] In this embodiment, two sets of side support plates 11 are symmetrically welded on the upper surface of the plastic bracket base 1; and the two sets of side support plates 11 are distributed at the rear shell of the plate heat exchanger 3.

[0022] As a preferred embodiment, the plastic support base 1, side support plate 11, and L-shaped limiting guard plate 2 are all made of PC material with high strength, high wear resistance, and high temperature resistance. This facilitates stable installation of the support plate heat exchanger 3.

[0024] As a preferred implementation, the L-shaped limiting guard plate 2 penetrates the surface of the side support plate 11 and limits and snaps onto the plate heat exchanger 3 on the plastic bracket base 1, so that the plate heat exchanger 3 can be quickly installed on the surface of the plastic bracket base 1, shortening the inspection and maintenance time of the plate heat exchanger 3, while avoiding the support frame from occupying the heat dissipation space of the heat exchanger fins.

[0025] In this embodiment, a groove 13 is provided on the surface of the plastic support base 1; and a connecting slider 41 slides in the groove 13. Two sets of connecting sliders 41 are provided on the lower surface of the vibration isolation base plate 4.
