[0014] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0015] Example

[0016] like Figure 1-2 As shown, a heat dissipation device for a refrigerator disclosed in the utility model includes a refrigerator body, an exhaust structure 1 and a blowing structure 2, the exhaust structure 1 includes an exhaust fan 101, a support frame 102 is installed at the bottom of the exhaust fan 101, and the bottom of the support frame 102 is fixed to the ground, the blowing structure 2 includes a hair dryer 201, a support base 202 is fixedly installed at the bottom of the hair dryer 201, and the support base 202 is fixed to the ground, an air supply tube 203 is installed on the rear side of the hair dryer 201, the air outlet end of the hair dryer 201 is wide in front and narrow in the back, the air inlet of the exhaust fan 101 is arranged at the heat dissipation end of the refrigerator body, and the hair dryer 201 is arranged obliquely below the exhaust fan 101.

[0017] The air outlet end of the exhaust fan 101 is fixedly connected with an air supply pipe 103 and a cold water tank 3 . The air supply pipe 103 is arranged to penetrate the cold water tank 3 . One end of the air supply pipe 103 away from the exhaust fan 101 penetrates into the air supply cylinder 203 .

[0018] The air outlet end of the hair dryer 201 , the air inlet end of the air supply cylinder 203 and the air inlet end of the exhaust fan 101 are all installed with a filter 4 .

[0019] A water inlet pipe 301 and a water outlet pipe 302 are installed on the side of the cold water tank 3 away from the exhaust fan 101. The height of the water outlet pipe 302 is higher than that of the water inlet pipe 301. The water outlet pipe 302 and the water inlet pipe 301 are both connected to the water storage place. Water flows into the cold water tank 3 from the water inlet pipe 301. The water in the cold water tank 3 overflows from the water outlet pipe 302 when it is full.

[0020] The specific implementation method of this example is as follows: the refrigerator body is cooled by the hair dryer 201, and the hot air at the heat dissipation end of the refrigerator body is extracted by the exhaust fan 101. The extracted hot air passes through the air supply pipe 103, and is cooled under the action of the cold water tank 3, and then is transmitted to the air supply tube 203. After the hair dryer 201 cools down, it acts on the refrigerator body again. Moreover, the temperature of the hot air after cooling is lower than the outside temperature, and the cooling effect is more significant. Water is passed into the cold water tank 3 through the water inlet pipe 301. When the water in the cold water tank 3 is full, it overflows to the water outlet pipe 302 and is then transmitted to the water storage place, thereby realizing cold water circulation and avoiding the temperature increase and the decrease of the cooling effect after long-term use.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
