All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the prior art, household appliances such as televisions, computers, exhaust fans and the like are driven by electric energy, and common household appliances are wrapped by shells for the purposes of integral attractiveness and safety in the using process. Meanwhile, heat energy generated in the working process of the equipment is filled in an inner cavity wrapped by the shell, so that the traditional electric appliance is provided with heat dissipation holes on the shell.

For example, the backlight surface of a television device is often provided with heat dissipation holes; however, when the heat dissipation holes are arranged, the heat dissipation space on the shell is fixed, and when the television equipment is upgraded and updated, even if the appearance is unchanged, the heat dissipation speed of the upgraded internal hardware is different, and the heat dissipation holes on the original shell cannot be matched with enough heat dissipation efficiency, so that the shell has to be produced again; in addition, when the television equipment is used in a high-temperature environment in summer or a low-temperature environment in winter, the heat dissipation efficiency of the shell is invariable, and the shell cannot be adaptively adjusted according to the environment, so that the heat in the inner cavity of the television equipment is easily discharged out in time, the failure of the television equipment is possibly caused, and the service life of the television equipment is shortened.

The same is true on other electrical equipment, and the shell on the traditional equipment can not flexibly adjust the heat dissipation efficiency, so that the defect that the shell can not meet the heat dissipation requirements under different use conditions can be generated.

Referring to fig. 1, in an embodiment of the present application, a heat dissipation rear housing is disclosed, wherein the heat dissipation rear housing includes a back frame 10 and a heat dissipation structure 20, and a hollow groove 11 is formed on the back frame 10; the heat dissipation structure 20 is disposed in the hollow groove 11, and detachably connected to the back frame 10.
