[0049] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts belong to the scope of protection of the present invention.

[0050] To overcome the defects of the existing heat dissipation technology of the whole machine air conditioner, the present invention proposes a new air conditioner box heat dissipation structure. Figure 1 It is an overall schematic diagram of the air conditioner heat dissipation structure provided by the present invention, as Figure 1 shown, including:

[0051] A box assembly and a housing assembly, the box assembly is located inside the housing assembly and is perpendicular to the bottom of the housing assembly;

[0052] An outdoor air duct and an indoor air duct are arranged in parallel inside the housing assembly close to the top;

[0053] The box assembly is located between the outdoor air duct and the indoor air duct, sucks in external air through the negative pressure formed by the outdoor air duct, and discharges the external air to the indoor air duct.

[0054] First, the air conditioner cabinet heat dissipation structure proposed by the present invention is mainly for the whole machine air conditioner. Therefore, from the outside, it includes Figure 1 The outer shell assembly 17 shown in Figure, which constitutes the external component of the heat dissipation structure. As Figure 2 Shown in the schematic diagram of the internal overall structure, the core component inside is the cabinet assembly 5. At the inner top of the outer shell assembly 17, an outdoor air duct 4 and an indoor air duct 6 are respectively arranged in parallel. The cabinet assembly 5 is located between the outdoor air duct 4 and the indoor air duct 6.

[0055] Place the cabinet assembly 5 between the indoor air duct 4 and the outdoor air duct 6, and in the middle of the side close to the edge. As Figure 2 Shown as the middle on the left side in the figure. Utilize the negative pressure generated by the outdoor air duct 4 to make the air on the outside form wind, enter the cabinet assembly 5 through the air inlet, and then be discharged from the exhaust hole on the back of the cabinet assembly 5, thereby forming a circulating wind to achieve the purpose of rapid heat dissipation.

[0056] The present invention sets an air inlet and an air outlet in the overall cabinet of the air conditioner, and utilizes the circulating air flow of the whole machine to make the outside air circulate with the hot air inside the cabinet, achieving the effect of rapid heat dissipation, and also enabling the air conditioner cabinet to have the functions of waterproof and ventilation.

[0057] On the basis of the above embodiment, the cabinet assembly includes a cabinet box cover assembly and a cabinet body assembly, and the cabinet box cover assembly is assembled with the cabinet body assembly through fasteners.

[0058] Among them, the cabinet box cover assembly includes a cabinet box cover fireproof sheet metal and a cabinet box cover;

[0059] The cabinet box cover fireproof sheet metal is located outside the cabinet box cover. The side of the cabinet box cover fireproof sheet metal is provided with a cabinet box cover fireproof sheet metal air inlet, and the cabinet box cover fireproof sheet metal air inlet is vertically arranged with the front section of the cabinet box cover. The front section of the cabinet box cover is perpendicular to the bottom of the outer shell assembly;

[0060] The side of the cabinet box cover is provided with a cabinet box cover air inlet, and the cabinet box cover air inlet is arranged in parallel with the cabinet box cover fireproof sheet metal air inlet.

[0061] Among them, the cabinet body assembly includes a cabinet fireproof sheet metal and a cabinet body;

[0062] The cabinet fireproof sheet metal is located outside the cabinet body. The section of the cabinet fireproof sheet metal is provided with a cabinet fireproof sheet metal air outlet, and the cabinet fireproof sheet metal air outlet is vertically arranged with the cabinet box cover fireproof sheet metal air inlet;

[0063] The front section of the cabinet body is provided with a cabinet air outlet, and the cabinet air outlet is arranged in parallel with the cabinet fireproof sheet metal air outlet. The front section of the cabinet body is perpendicular to the bottom of the outer shell assembly.

[0064] Furthermore, the box body assembly 5 can be split into a box body cover assembly and a box body main body assembly, and the two parts are fixed by fasteners.

[0065] It can be understood that setting a sheet metal assembly on the whole box body assembly 5 can play a good protective role for the box body. For example, Figure 3 as shown, a box body cover fireproof sheet metal 7 is arranged outside a part of the box body cover assembly, and a box body fireproof sheet metal 9 is arranged outside a part of the box body main body assembly. An air inlet 8 of the box body cover fireproof sheet metal is arranged on the side of the box body cover fireproof sheet metal 7. Correspondingly, an air outlet 10 of the box body fireproof sheet metal is arranged on the back of the box body fireproof sheet metal 9.

[0066] Another example is Figure 4 as shown, inside the sheet metal assembly, a box body cover 11 and an air inlet 12 on its side, as well as a box body main body 16 and an air outlet on its back are correspondingly arranged.

[0067] The air inlet 8 of the box body cover fireproof sheet metal and the air inlet 12 of the box body cover are closely attached together. In addition, the air outlet 14 of the box body and the air outlet 10 of the box body fireproof sheet metal are also closely attached together, thus forming a smooth air duct to enable the smooth circulation of external wind energy.

[0068] After being combined, the box body and the box body fireproof sheet metal are pre-assembled together to form the box body main body assembly, as Figure 5 shown; the box body cover and the box body cover fireproof sheet metal are assembled together to form the box body cover assembly, as Figure 6 shown.

[0069] By setting a sheet metal assembly outside the box body assembly in the present invention, a good protective effect can be achieved, enabling the box body main body installed inside to have a better heat dissipation function. At the same time, air inlets and air outlets are arranged at corresponding positions, which is conducive to the circulation of hot air and achieves an ideal heat dissipation effect.

[0070] Based on the above embodiments, the box body main body further includes a radiator and a reinforcing plate. The radiator is fixed to the box body main body through the reinforcing plate, and the reinforcing plate is attached to the box body main body.

[0071] Among them, the radiator is close to the air outlet of the box body.

[0072] Optionally, in the present invention, a radiator 13 is further arranged at the top position of the box body main body inside the box body assembly 5, as Figure 6 shown. The radiator 13 is fixed to the box body main body 16 by a reinforcing plate 15, as Figure 7As shown, the strong board 15 functions as a circuit board and is fixed to the box body 16. Then, the radiator 13 is fixed to the strong board 15, near the top of the box body 16 and close to the air outlet 14 of the box body.

[0073] The radiator 15 cooperates with the air inlet and the air outlet, which can achieve a better heat dissipation effect and can maximize the diffusion of the heat inside the box body to the outside through hot air.

[0074] On the basis of the above embodiments, the box cover is fixed to the box body with screws, and the fireproof sheet metal of the box cover is fixed to the fireproof sheet metal of the box body with the screws.

[0075] It can be understood that, as Figure 8 shown, the box cover 11 and the box body 16 are fixed with screws, and as Figure 9 shown, the fireproof sheet metal 7 of the box cover and the fireproof sheet metal 9 of the box body are also fixed with screws.

[0076] In the present invention, the box cover and the box body are respectively fixed with screws, and the fireproof sheet metal of the box cover and the fireproof sheet metal of the box body are respectively fixed, making the box body assembly structure more firm and facilitating the setting of corresponding air inlets and air outlets.

[0077] On the basis of the above embodiments, the housing assembly includes a housing and a chassis;

[0078] The housing is fastened on the chassis and forms a closed housing assembly with the chassis;

[0079] The outdoor air duct, the indoor air duct and the box body assembly are all located inside the housing;

[0080] The outdoor air duct and the indoor air duct are both parallel to the chassis;

[0081] The box body assembly is parallel to the outdoor air duct and the indoor air duct respectively, perpendicular to the chassis, and located at any side position in the middle of the chassis.

[0082] Among them, the housing is provided with a housing air inlet;

[0083] The housing air inlet is located on the side of the housing. The side of the housing is perpendicular to the box body assembly and the chassis respectively, and is located on the side of the air inlet of the box cover.

[0084] Specifically, for the housing assembly 17, it specifically includes a housing 1 and a chassis 3, as Figure 1 and Figure 2 shown.

[0085] Among them, the side of the housing 1 is provided with a housing air inlet 2, which is opposite to the air inlet on the box body assembly 5.

[0086] It is understandable that the external hot air enters through the negative pressure formed by the outdoor air duct 4 and enters through the air inlet 2 of the housing, as Figure 10 shown by the arrow direction. Then, after the air comes in from the outside, it passes through the fireproof sheet metal of the box cover of the box body and the box cover of the box body and enters the box body cavity, as Figure 11 shown by the arrow direction. Finally, it is discharged from the air outlet on the back of the box body assembly 5 to form a circulating gas, as Figure 12 shown by the arrow direction.

[0087] The present invention uses the method of circulating gas + radiator for heat dissipation. The box body is placed between the indoor air duct and the outdoor air duct, in the middle on the left side. By using the negative pressure of the outdoor air duct, the outside air can enter through the air inlet of the housing, and then enter the box body cavity through the air inlet of the box cover of the box body, and is discharged from the exhaust hole on the back of the box body, thus forming a circulating wind, making it have the characteristics of waterproof, ventilation and effective heat dissipation.

[0088] Based on the above embodiments, the present invention also provides an air conditioner, which includes the above-mentioned air conditioner box body heat dissipation structure and is installed as the outer shell of the whole air conditioner.

[0089] During installation, first place the chassis 3, then install the box body assembly 5, the outdoor air duct 4 and the indoor air duct 6, and at the same time install other components in the air conditioner box body. After completion, fasten the housing 1 tightly on the chassis 3 to complete the installation of the whole machine.

[0090] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
