Description

Technical Field

[0001] This utility model relates to the field of vehicle refrigerator technology, and in particular to an external compressor type vehicle refrigerator with an optimized refrigeration system. Background Technology

[0002] In the trucking sector, the market has placed more stringent demands on the core performance and space utilization efficiency of vehicle-mounted refrigerators. However, the current traditional condenser layout design of vehicle-mounted refrigerators has significant drawbacks and is no longer suitable for these requirements. Specific problems are as follows: Firstly, the space utilization efficiency is low, which restricts transportation efficiency. Most traditional vehicle refrigerators integrate the condenser into the refrigerator body. Although this design simplifies the initial assembly process, it seriously occupies the limited storage space inside the refrigerator. Since the condenser needs to occupy a certain installation space and heat dissipation gap, it directly leads to the compression of the effective volume of the refrigerator, which cannot be maximized. Secondly, existing products generally require additional cooling fans for forced auxiliary cooling. The addition of cooling fans and supporting power supply circuits directly increases the production and manufacturing costs of vehicle refrigerators. On the other hand, the operation of the fans requires continuous consumption of the truck's onboard power supply, which will increase the vehicle's operating energy costs in the long run. Utility Model Content

[0003] The purpose of this invention is to provide an external compressor type vehicle refrigerator with an optimized refrigeration system to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution, which includes a refrigerator body, a refrigerator door that is movably mounted on one side of the front of the refrigerator body via several hinges, a mounting chamber that is opened on the upper back of the refrigerator body, a refrigeration module that is mounted in the mounting chamber, a condenser of the refrigeration module that is mounted on the back of the refrigerator body, and several mounting plates that are mounted on the back of the condenser that are fixed to the back of the refrigerator body by screws.

[0005] As a preferred embodiment of this invention, the placement chamber is provided with a protective cover, and the protective cover has several heat dissipation slots.

[0006] As a preferred embodiment of this utility model, a pair of U-shaped frames are provided on the outer wall of the refrigerator body, and each U-shaped frame is provided with a top plate on its top, and both sides of the top plate are fixed to the bottom of the truck frame by bolts.

[0007] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: The condenser of this invention is fixed to the back of the refrigerator body with several mounting plates, which are fully exposed to the external air circulation environment, greatly increasing the heat dissipation contact area. At the same time, the compressor of the refrigeration module, together with the strip heat dissipation groove on the protective cover of the installation chamber, forms a dual heat dissipation structure of active ventilation and large-area heat dissipation, which can quickly dissipate the heat generated by the refrigeration module when it is working, avoid heat accumulation that leads to a decrease in refrigeration efficiency, and keep the internal temperature of the refrigerator stable within the set range.

[0008] This invention utilizes a highly efficient natural heat dissipation structure, eliminating the need for an additional cooling fan. This directly reduces the procurement and assembly costs of the fan and its associated circuitry, lowering the overall production cost and enhancing market competitiveness. Furthermore, it reduces the probability of repairs due to fan failure, extending the overall lifespan of the refrigerator. Attached Figure Description

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0012] like Figures 1-6 As shown, the present invention proposes an external compressor type vehicle refrigerator with an optimized refrigeration system, which includes a refrigerator body 1. Three hinges 5 are arranged at intervals along the height direction on one edge of the front side of the refrigerator body 1, and the other side is fixed to the corresponding edge of the refrigerator door 2. Above the back of the refrigerator body 1, there is a mounting chamber 3. The depth of the mounting chamber 3 matches the thickness of the refrigeration module 4 to ensure that the refrigeration module 4 can be fully installed in it. The refrigeration module 4 is fixed to the bottom surface of the mounting chamber 3 with screws. The condenser 40 extends and is fixed to the back of the refrigerator body 1. To protect the refrigeration module 4 and the condenser 40, a protective cover 30 is installed at the opening of the mounting chamber 3. Several strip-shaped heat dissipation grooves 31 are evenly opened on the side wall and top of the protective cover 30. This can prevent external debris from entering the mounting chamber 3 without affecting the normal heat dissipation of the refrigeration module 4. At the same time, four metal mounting plates 6 are provided on the back of the condenser 40. The mounting plates 6 are welded and fixed to the condenser 40. After passing through the preset holes of the mounting plates 6, they are screwed into the threaded holes on the back of the refrigerator body 1 by cross screws 60, which further enhances the connection stability between the condenser 40 and the refrigerator body 1 and prevents the condenser 40 from falling off due to vehicle bumps. On the outer wall of the refrigerator body 1, a pair of U-shaped frames 7 are fixed. Each U-shaped frame 7 has a horizontally set top plate 70. During assembly, the two top plates 70 are respectively attached to the preset installation positions at the bottom of the truck frame. Then, using bolts of appropriate specifications, the bolts are passed through the preset bolt holes on both sides of the top plate 70 and the corresponding mounting holes at the bottom of the truck frame. After tightening the bolts, the refrigerator body 1 is rigidly fixed to the truck frame, effectively preventing the refrigerator body 1 from shifting during vehicle operation.

[0013] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
