Description

Technical Field

[0001] This utility model relates to the field of microwave oven heat dissipation structure, and in particular to a reinforced heat dissipation structure for a vehicle-mounted microwave oven microwave source. Background Technology

[0002] The vehicle-mounted microwave oven has two adjacent chambers: a cooking chamber and a microwave source mounting chamber. The microwave source is mounted in the microwave source mounting chamber via a bottom bracket, and a cooling fan is installed on one side of the microwave source.

[0003] In the aforementioned prior art, since the cooling fan is only installed on one side of the microwave source, there is often a problem of poor heat dissipation. Furthermore, the microwave source is only connected to the microwave source mounting cavity through the bottom bracket, which leads to instability during vehicle movement. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a reinforced heat dissipation structure for the microwave source of a vehicle-mounted microwave oven. This solves the problem of poor heat dissipation caused by installing a cooling fan only on one side of the microwave source in traditional technologies, as well as the problem of instability of the microwave source caused by connecting the microwave source and the microwave source mounting cavity only through the bottom bracket.

[0005] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0006] A reinforced heat dissipation structure for a microwave source of a vehicle-mounted microwave oven includes a housing with a cavity formed on one side. The microwave source is disposed within the cavity, and the top and bottom surfaces of the microwave source are fixed to the inner wall of the cavity by a top bracket and a bottom bracket, respectively. A set of cooling fans is installed on the outer walls of the microwave source near the front and back sides of the housing.

[0007] Preferably, the top bracket is frame-shaped with a stepped arrangement between the two connecting ends. The top bracket can provide stable support for the microwave source from the top, ensuring that the microwave source will not shift due to bumps during vehicle operation.

[0008] Preferably, the top support includes an upper U-shaped frame and a lower U-shaped frame with opposite openings. The corresponding ends of the two U-shaped frames are connected as one unit by a connecting plate. The upper U-shaped frame is connected to the housing 1, and the lower U-shaped frame is connected to the top surface of the microwave source.

[0009] Preferably, the bottom support includes a support shell fixed to the bottom surface of the inner wall of the cavity, a U-shaped strip fixed to the top surface of the support shell, side plates at both ends of the U-shaped strip being fixed to the longitudinal outer wall of the microwave source, and the bottom plate of the U-shaped strip being fixed to the bottom surface of the microwave source.

[0010] Preferably, each side of the support shell has a protruding reinforcing strip, which can improve the load-bearing capacity of each side of the support shell and increase the strength of the support shell.

[0011] Preferably, each set of cooling fans is distributed at equal intervals from top to bottom, and the two sets of cooling fans are symmetrically arranged on both sides of the microwave source, which has good stability and heat dissipation effect.

[0012] Preferably, the support shell is located in the middle position directly below the microwave source, ensuring stable installation, and the top surface of the support shell is fixed to the bottom surface of the microwave source.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] This invention installs a set of cooling fans on the outer walls of the microwave source near the front and back of the housing. Compared with the traditional method of setting a cooling fan on only one side, it forms a more comprehensive and efficient heat dissipation airflow, which greatly enhances the heat dissipation capacity, effectively reduces the operating temperature of the microwave source, ensures its stable operation, and extends its service life.

[0015] The top and bottom surfaces of the microwave source are fixed to the inner wall of the cavity by top and bottom brackets, respectively. This multiple fixing method greatly improves the stability of the microwave source during vehicle movement, ensuring the stability of the microwave source fixation even with an increased number of cooling fans, and reducing the risk of component loosening or damage due to vibration.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 3This embodiment provides a reinforced heat dissipation structure for a microwave source of a vehicle-mounted microwave oven, including a housing 1. A cavity 2 is formed on one side of the housing 1. The microwave source 6 is disposed in the cavity 2. A set of cooling fans 3 are respectively installed on the outer walls of the front and back sides of the microwave source 6. Each set of cooling fans 3 is distributed at equal intervals from top to bottom. By rotating the cooling fans 3, the heat on the surface of the microwave source 6 is removed, thereby realizing the heat dissipation of the microwave source 6.

[0022] The cooling fans 3, which are evenly spaced on both sides, can form a uniform cooling airflow on both sides of the microwave source 6, covering the microwave source 6 in all directions, effectively removing the heat generated during operation, greatly improving the heat dissipation efficiency, avoiding performance degradation or damage to the microwave source 6 due to overheating, and ensuring the stable operation of the microwave source 6.

[0023] A top support 4 is fixed to the top surface of the microwave source 6. The side of the top support 4 away from the microwave source 6 is fixed to the inner wall of the cavity 2. The top support 4 is frame-shaped with a stepped arrangement between the two connecting ends. The top support 4 includes an upper U-shaped frame 401 and a lower U-shaped frame 402 with opposite openings. The corresponding ends of the two U-shaped frames are connected as one unit by a connecting plate 403. The upper U-shaped frame 401 is connected to the housing 1, and the lower U-shaped frame 402 is connected to the top surface of the microwave source. Thus, the top support 4 can provide stable support for the microwave source 6 from the top, ensuring that the microwave source 6 will not shift due to bumps during vehicle operation, thereby ensuring the connection stability of the microwave source 6 with other components and maintaining its normal working state.

[0024] The bottom surface of the microwave source 6 is connected to the inner wall of the cavity 2 via a bottom support 5. The bottom support 5 includes a support shell 502 fixed to the bottom surface of the inner wall of the cavity 2. The support shell 502 is located in the middle position directly below the microwave source 6. A U-shaped strip 501 is fixed to the top surface of the support shell 502. The side plates at both ends of the U-shaped strip 501 are fixed to the longitudinal outer wall of the microwave source 6. The bottom plate of the U-shaped strip 501 is fixed to the bottom surface of the microwave source 6. A protruding reinforcing strip 5021 is formed on each side of the support shell 502. The protruding reinforcing strip 5021 can improve the load-bearing capacity of each side of the support shell 502, improve the strength of the support shell 502, and make it have a better support effect.

[0025] The bottom bracket 5 provides a stable support base for the microwave source 6 from the bottom and is located between the cooling fans 3, so as not to affect the flow of cooling air. At the same time, together with the top bracket 4, it can use its own structure to stabilize the microwave source 6 and improve the stability of the microwave source 6.

[0026] 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.
