[0014] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described below by specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0015] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.
[0016] See Figure 1-Figure 2 As shown, this specific embodiment adopts the following technical scheme: it includes a car refrigerator 1, a car refrigerator door body 2, an exhaust gas circulation pipe 3, a solenoid valve 4, a car exhaust pipe 5, and a car engine 6; the car engine 6 is connected to the car exhaust pipe 5, wherein one side of the car exhaust pipe 5 is connected to the U-shaped exhaust gas circulation pipe 3, the middle of the air intake section of the exhaust gas circulation pipe 3 is connected to the solenoid valve 4, and the middle section of the exhaust gas circulation pipe 3 is connected to the inside of the car refrigerator 1, so that the fitting surface and inner wall of the car refrigerator door body 2 and the car refrigerator 1 are preheated and defrosted.
[0017] The exhaust gas circulation pipe 3 and the automobile exhaust pipe 5 are seamlessly connected by welding; the diameter of the exhaust gas circulation pipe 3 is one third of the automobile exhaust pipe 5. Since the exhaust temperature of the automobile exhaust pipe 5 is too high, the temperature is adjusted by changing the intake volume by changing the diameter.
[0018] In addition, the exhaust gas circulation pipe 3 is connected to the middle and rear section of the automobile exhaust pipe 5; the exhaust gas circulation pipe 3 is a double-layer structure, and the middle of the sleeve is filled with insulation material to protect the safety during heat transfer, and the exhaust gas circulation pipe 3 connected to the vehicle refrigerator 1 remains exposed.
[0019] The working principle of this specific implementation method is as follows: an exhaust gas circulation pipe 3 is led out from the automobile exhaust pipe 5 to the door frame of the vehicle refrigerator 1; and a solenoid valve 4 is installed at the air inlet end of the exhaust gas circulation pipe 3 to control the defrosting temperature of the door frame. The temperature is controlled by the conduction time. Since the temperature of the exhaust gas from the automobile exhaust pipe 5 is relatively high, the temperature can only be controlled by intermittent ventilation; when the solenoid valve 4 is turned on, the high-temperature waste heat exhaust gas of the automobile engine will pass through the exhaust gas circulation pipe 3 around the door frame and then return to the automobile exhaust pipe 5; the high-temperature waste heat exhaust gas will melt the frost on the door body, and the frost on the door body will also cool the high-temperature waste heat exhaust gas, thereby achieving energy saving and environmental protection.
[0020] This specific implementation method eliminates the traditional heating wire defrosting structure, fully utilizes the heat of exhaust gas, saves the electric energy used for defrosting other electrical equipment, and achieves energy-saving effect; at the same time, it cools the exhaust gas of the car and protects the environment.
[0021] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
[0022] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
