Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0017] Please see Figures 1 to 5 A water source multi-split air conditioner housing structure includes a top cover 1, a front panel 2, a frame 3, a bottom panel 4, side panels 5, a rear panel 6, and a base 7. The frame 3 stands on the base 7 and is fixedly connected to the base 7. The base 7 is rectangular. The frame 3 includes columns 31, a rear crossbeam 32, side crossbeams 33, and an electrical control box 34. There are four columns 31, which are fixed to the four corners of the base 7. The side crossbeams 33 are fixed to the top of the columns 31 located on the two short sides of the base 7. The rear crossbeam 32 is fixed to the top of the columns 31 located on one long side of the base 7. The side panels 5 are tightly attached to the columns 31 and the side crossbeams 33 and fixed. The rear panel 6 is tightly attached to the columns 31 and the rear crossbeams 32 and fixed. The electrical control box 34 is fixed to the top of the columns 31 located on the other long side of the base 7. The front panel 2 is tightly attached to the columns 31 and the electrical control box 34 and fixed. The top cover 1 is fixed to the top of the frame 3. A bottom opening in the front panel 2 connects to a lower panel 4. The lower panel 4 has an opening 40 through which refrigerant pipes and unit wiring extend. For after-sales service, only the front panel 4 needs to be removed for internal component repair. In this embodiment, the housing structure is based on the frame 3, whose top cover 1, side panels 5, front panel 2, and rear panel 6 can all be independently disassembled for easy maintenance. The connections can be made using various detachable methods such as screws, clips, and riveting.

[0018] In a preferred embodiment of this invention, the base 7 includes a front foot 71, side feet 72, a rear foot 73, a water tray 74, a central support 75, and side supports 76. The water tray 74 is rectangular, with the front foot 71 and rear foot 73 fixed to its two long sides respectively. There are two central supports 75 and two side supports 76, with the two central supports 75 arranged parallel to each other in the middle of the water tray 74. A side support 76 is connected to each of the left and right sides, and the side supports 76 are connected to the front foot 71 and rear foot 73 respectively. There are also two side feet 72, located on the two short sides of the water tray 74 respectively, and connected to the front foot 71, rear foot 73, and side supports 76. Similarly, the connection method between the various components of the base 7 is one of screws, clips, or riveting. The various components of the base can be disassembled and can be powder-coated along with the panel, ensuring color consistency of the unit. Currently, machines on the market generally use welding for the base, which reduces costs but prevents powder coating along with the panel, thus failing to achieve a uniform color.

[0019] Furthermore, the front foot 71 and the rear foot 73 have through holes 77 for inserting the drain pipe of the water receiving tray 74.

[0020] In a preferred embodiment of this invention, the front panel 2 has two notches 20 for connecting water pipes.

[0021] In a preferred embodiment of this invention, the electrical control box 4 includes a refrigerant cooling module and a fan-cooled cooling module. The refrigerant cooling module includes a heat sink 8 and a refrigerant pipe 9, which is fixed to the back of the refrigerant box 4 and contacts the inverter board 41 inside the electrical control box 4. The fan-cooled cooling module is located on one side of the refrigerant cooling module. In this embodiment, a cooling fan 10 is used, which is fixed to the electrical control box 4 above the reactor 11. An air inlet 42 is provided at the bottom of the electrical control box 4, and a high-efficiency heat sink 12 is provided above the air inlet 42. An air outlet 43 is provided behind the reactor 11 in the electrical control box 4. Figure 4 The arrows indicate the air intake and exhaust directions of the air conditioner. Normal temperature air enters through the air intake 42. After passing through the high-efficiency radiator 12, the normal temperature air becomes low temperature air. When the low temperature air passes through the main heat source, it neutralizes the heat dissipated by the heat source. After passing through the air outlet 43, it is blown out from above the reactor 11 by the cooling fan 10. At the same time, the inverter board 41 is in direct contact with the heat sink 8, which can also remove the main heat on the inverter board 41.

[0022] Since the electrical control box 4 of this application has both air-cooled heat dissipation module and refrigerant heat dissipation module, it does not need to dissipate heat from the outside. Therefore, none of the panels of the shell are provided with heat dissipation holes. The fully sealed structure without heat dissipation holes can significantly reduce the noise of the unit and prevent the noise of the internal compressor, electrical control, pipeline, etc. from being transmitted to the outside of the unit.

[0023] This embodiment also provides a water-source multi-split air conditioner using the above-described housing. The compressor 13 in the air conditioner is fixed on the side bracket 76, the gas-liquid separator 14 is fixed on the middle bracket, and the sleeve module 15 is fixed on another side bracket 76.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
