The second insulating pad 172 is further provided with a first through hole 173 and a second through hole 174, wherein the position of the first through hole 173 corresponds to the position of the air inlet 102, and the position of the second through hole 174 corresponds to the position of the air outlet 103. The provision of the first through-holes 173 and the second through-holes 174 provides a passage for air to enter the accommodating space 101.

In one embodiment, the first and second through holes 173 and 174 of the second insulating pad 172 are aligned with the first and second through holes of the pod 16, so that the air flow path is aligned to facilitate the air entering and exiting the pod 16. It will be appreciated that the first through hole 173 may also partially coincide with the first vent 161, and the second through hole 174 may also partially coincide with the second vent 162.

Referring to fig. 4, in an embodiment, the insulating pad 17 is further provided with a heat dissipation hole 175, and the heat conduction pad 15 is attached to the inner wall of the housing 10 through the heat dissipation hole 175, so that the heat sink 13 transfers heat to the housing 10.

On the one hand, the electric control box 100 passes through the air inlet 102, the air outlet 103 and the fan 14, so that air flows through the accommodating space 101 of the housing 10, and the air carries heat in the housing 10 to the outside of the housing 10. On the other hand, the heat of the electric control assembly 11 is absorbed by the radiator 13 and transferred to the outside of the shell 10 by heat conduction, so that the heat dissipation effect of the electric control box 100 is further improved, and the residual heat in the electric control box 100 is reduced.

Referring to fig. 1 and 5, another embodiment of the present application provides a portable air conditioner 200, which includes a cabinet 20, a heat exchange assembly (not shown), and an electronic control box 100 according to any of the above embodiments. The heat exchange assembly and the electric control box 100 are arranged in the shell 20, and the heat exchange assembly is electrically connected with the electric control box 100.

The electric control box 100 in the movable air conditioner 200 sucks air into the shell 10 through the fan 14 and transfers heat of the electric control assembly 11 to the outside of the electric control box 100 through the radiator 13, so that heat in the shell 10 can be taken away, heat accumulation in the electric control box 100 is reduced, heat in the shell 20 is transferred to the outside of the shell 20 through the heat exchange assembly, and the heat dissipation effect of components in the movable air conditioner 200 is improved.

In one embodiment, the heat exchange assembly includes a compressor, an evaporator, a condenser, a cold air blower, and a hot air blower connected to each other by wires. The cold air blower corresponds to the evaporator, and the hot air blower corresponds to the condenser. The casing 20 is provided with an electric outlet for accessing an external power supply. The electric control box 100 is electrically connected with the power socket, the compressor, the cold air blower and the hot air blower, and the electric control box 100 performs power conversion on the input current and outputs the converted input current to the compressor, the cold air blower and the hot air blower so as to realize the operation of the movable air conditioner 200.

In summary, the electric control box 100 in the movable air conditioner 200 sucks air into the casing 10 through the fan 14, and the air flows in the casing 10, so as to take away heat inside the electric control box 100, and transfer heat of the electric control assembly 11 to the outside of the electric control box 100 through the radiator 13, so that heat accumulation inside the electric control box 100 is reduced, the heat exchange assembly transfers heat inside the casing 20 to the outside of the casing 20, and the heat dissipation effect of components inside the movable air conditioner 200 is improved.

In addition, other variations within the spirit of the present application will occur to those skilled in the art, and of course, such variations as may be made in light of the spirit of the present application are intended to be included within the scope of the present disclosure.
