The electronic control box assembly 10 includes a heat dissipation assembly 11 and an electronic control board 12.

The heat dissipation assembly 11 includes a refrigerant pipe 111, a first heat dissipation plate 112, and a second heat dissipation plate 113. The first heat dissipation plate 112 and the second heat dissipation plate 113 are buckled to define a mounting cavity, and the refrigerant tube 111 is fixed in the mounting cavity. The first heat dissipating plate 112 accommodates the first portion 111a of the refrigerant pipe 111, and the second heat dissipating plate 113 accommodates the second portion 111b of the refrigerant pipe 111, and the volume of the first portion 111a is larger than the volume of the second portion 111b.

Preferably, the first heat sink 112 and the second heat sink 113 are made of metal, and more preferably, the first heat sink 112 and the second heat sink 113 are made of aluminum plate having good heat conductivity. The first heat dissipation plate 112 and the second heat dissipation plate 113 are also fixedly connected by screws, for example.

Specifically, the two ends of the bracket 13 are respectively used for being attached to the first outer wall 1121 and the first surface 122, and the bracket 13 is attached to at least the outer peripheral wall of the heating element 1211, so that the first cooling plate 112 cools the heating element 1211 through the bracket 13.
