Description

Technical Field

[0001] The utility model relates to the field of air conditioner outdoor unit equipment, in particular to an installation structure of a plate heat exchanger for an air conditioner outdoor unit. Background Technique

[0002] Air conditioners are widely used household appliances. For some existing air conditioners, in order to improve the system capacity, a plate heat exchanger (hereinafter referred to as a plate exchanger) is arranged in the outdoor unit, thereby improving the corresponding performance. Among them, the existing plate heat exchangers are generally installed on the partition plate in the outdoor unit.

[0003] There are generally two common installation methods for plate heat exchangers: The first method is that two fixing bolts protrude from the plate heat exchanger and are fixed on the middle partition plate by nuts. This solution requires welding bolts on the plate heat exchanger, which increases the processing complexity of the plate heat exchanger and is not conducive to the transportation and storage of the plate heat exchanger. The second method is to use an installation support structure to fix the plate heat exchanger on the middle partition plate. The installation support structure of this solution generally uses multiple parts to fix the plate heat exchanger in the up and down, left and right, and front and back directions. For example, structures such as a bottom support plate and a lateral limiting plate are used to achieve fixation, but such an installation method is relatively complex. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an installation structure of a plate heat exchanger for an air conditioner outdoor unit that can conveniently and reliably install the plate heat exchanger on the middle partition plate.

[0005] The technical solution adopted by the utility model to solve its technical problems is: an installation structure of a plate heat exchanger for an air conditioner outdoor unit, including the middle partition plate of the outdoor unit and the plate heat exchanger. The plate heat exchanger is fixedly arranged on the middle partition plate through an installation support structure. The installation support structure includes a bottom support plate arranged on the surface of the middle partition plate and two lateral limiting plates. The bottom surface of the plate heat exchanger is arranged on the bottom support plate, and the plate heat exchanger is arranged between the two lateral limiting plates. The installation support structure includes a slot cover and an installation card plate arranged on the surface of the middle partition plate. The plate heat exchanger is arranged between the installation card plate and the middle partition plate. The left flanging of the installation card plate is clamped and fixed in the slot cover, and the right flanging of the installation card plate is fixedly arranged on the middle partition plate through a positioning screw.

[0006] Further, the slot cover includes a slot flanging, the slot flanging is bent towards the middle partition plate direction, and the left flanging includes an installation card plate limiting notch, and the slot flanging is clamped and arranged in the installation card plate limiting notch.

[0007] Further, the installation card plate is a U-shaped bending structure, the left flanging extends to the left, the right flanging extends to the right, and the left flanging and the right flanging are arranged on the same horizontal plane.

[0008] Furthermore, the right flanging is provided with screw holes for positioning screws to pass through.

[0009] Furthermore, the cross-sectional shapes of the bottom support plate and the lateral limiting plate are L-shaped.

[0010] Furthermore, the bottom support plate includes reinforcing ribs.

[0011] Furthermore, the lateral limiting plate includes reinforcing ribs.

[0012] Furthermore, the middle partition plate and the bottom support plate as well as the two lateral limiting plates are of an integral structure.

[0013] The beneficial effects of the present utility model are as follows: During actual installation, first, the plate heat exchanger is placed on the bottom support plate and between the two lateral limiting plates. At this point, the plate heat exchanger obtains a preliminary limit through the bottom support plate and the two lateral limiting plates, but the plate heat exchanger still needs further limitation at this time. Subsequently, the left flanging of the installation card plate is inserted into the card slot cover, and then the right flanging of the installation card plate is fixedly arranged on the middle partition plate through positioning screws, and the plate heat exchanger is arranged between the installation card plate and the middle partition plate, thereby firmly fixing the plate heat exchanger on the middle partition plate. This structure not only ensures the stable fixation of the plate heat exchanger but also makes the fixation process more convenient, greatly improving the operation convenience.

[0014] The present utility model is particularly applicable to the installation of the plate heat exchanger in the air conditioner outdoor unit. Description of the Drawings
