Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted refrigerators, in particular to a vehicle-mounted refrigerator with enhanced temperature conduction capability. Background Art

[0002] Car refrigerators are divided into two categories, one with only cooling capability and the other with heating capability, so that the food in the box can be kept at a constant temperature and kept warm. However, the inner tank of the current car refrigerator includes side walls and a bottom plate. The side walls are generally made of metal, while the bottom plate is made of engineering plastics. This results in the inner tank's ability to conduct temperature being relatively insufficient. The heating element and evaporator can only be set on the outside of the side walls and then conduct the temperature to the box through the side walls. This structure takes a long time to heat up or cool down the box to the required temperature, which results in more heat or cold dissipated, resulting in greater energy consumption. Utility Model Content

[0003] In order to solve the above problems, the purpose of this solution is to provide a car refrigerator with stronger temperature conduction capability.

[0004] The technical solution adopted by the utility model to solve the problem is: a vehicle refrigerator with enhanced temperature conduction capability, comprising:

[0005] An inner liner, the inner liner comprising an annular side plate and a bottom plate located at the bottom of the side plate, the side plate and the bottom plate are both made of heat-conducting metal;

[0006] The box shell is provided with an inner liner installed in the box shell, and a heat insulating layer is filled between the box shell and the inner liner.

[0007] As a further improvement of the above technical solution, it also includes a heating body, which is arranged on the outside of the inner tank and is in contact with the outer surfaces of the side panels and the bottom panel.

[0008] As a further improvement of the above technical solution, the horizontal cross-section of the side panel is square.

[0009] As a further improvement of the above technical solution, the heating body is attached to three of the four outer surfaces of the side plate.

[0010] As a further improvement of the above technical solution, the side plate is formed by connecting a plate body end to end to form a ring.

[0011] As a further improvement of the above technical solution, a cavity is formed on the top of the bottom plate, the bottom of the side plate is inserted into the cavity, and the outer surface of the side plate is fitted and fixed to the inner side surface of the cavity.

[0012] As a further improvement of the above technical solution, an evaporator is arranged on the outside of the inner tank, and the evaporator is bonded to the outer surfaces of the side panels and the bottom panel.

[0013] The beneficial effect of the utility model is that by setting the side panels and the bottom panel of the inner tank to be heat-conducting metal, the temperature of the heating body and the evaporator installed on the outside of the inner tank can be conducted not only along the side panels but also along the bottom panel when heating or cooling the inner tank, so that the temperature conduction ability is stronger, and the time for controlling the inner tank to the required temperature is shortened, thereby reducing energy consumption.

[0020] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0021] Reference Figure 1 to Figure 2 , a vehicle refrigerator with enhanced temperature conduction capability, comprising:

[0022] The inner liner 10 includes an annular side plate 11 and a bottom plate 12 located at the bottom of the side plate 11, and the side plate 11 and the bottom plate 12 are both made of heat-conducting metal;

[0023] The box shell 20, the inner liner 10 is installed in the box shell 20, and a heat insulation layer is filled between the box shell 20 and the inner liner 10.

[0024] By setting the side panels 11 and the bottom panel 12 of the inner tank 10 to be heat-conducting metals, when the heating body 30 and the evaporator installed on the outside of the inner tank 10 heat or cool the inner tank 10, the temperature is not only conducted along the side panels 11, but also along the bottom panel 12, so that the temperature conduction ability is stronger, and the time to control the inner tank 10 to the required temperature is shortened, thereby reducing energy consumption.

[0025] In the present embodiment, the evaporator or the heating body 30 can be only attached to the outer surface of the side plate 11. Since the bottom plate 12 is also made of heat-conductive metal, the temperature of the evaporator or the heating body 30 will quickly spread to the bottom plate 12 and be conducted to the inner tank 10 through the bottom plate 12. In order to make the temperature conduction ability stronger and reduce the distance of temperature conduction, it is preferred that the heating body 30 is attached to the outer surfaces of the side plate 11 and the bottom plate 12, and the evaporator is attached to the outer surfaces of the side plate 11 and the bottom plate 12.

[0026] In the traditional method, since the base plate 12 is made of engineering plastic, when the evaporator or the heating element is arranged at the bottom of the base plate 12, the thermal conductivity is poor, especially when the heating element is used for heating, which will cause heat to accumulate at the bottom of the base plate 12.

[0027] In this solution, the horizontal cross-section of the side panel 11 is preferably square.

[0028] In this solution, the heating body 30 is preferably attached to three of the four outer surfaces of the side plate 11 .

[0029] In this solution, the side plate 11 is preferably formed by connecting one plate end to end to form a ring, thereby saving costs. The ring-shaped side plate 11 can also be formed by welding several plates.

[0030] In this solution, in order to facilitate processing, it is preferred that a cavity is formed on the top of the bottom plate 12, the bottom of the side plate 11 is inserted into the cavity, and the outer surface of the side plate 11 is fixedly attached to the inner side of the cavity.

[0031] In other embodiments, the side plate 11 and the bottom plate 12 may also be integrally formed by stamping.

[0032] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
