Detailed Description

In order to facilitate understanding of the present invention, the following description is further provided with reference to the accompanying drawings.

As shown in fig. 1 and 2, outer machine compressor of air conditioner side cavity heat radiation structure improve acoustic celotex board 400, set up a plurality of air intakes 410 and a plurality of air outlets 420 respectively at the both ends of acoustic celotex board 400, utilize air intake 410 and air outlet 420 to form a plurality of air current guide passageways in quick-witted case 100, let the air current that gets into in quick-witted case 100 be guided to the automatically controlled subassembly 200 that is located acoustic celotex board 400 the place ahead and near compressor 300 carry out the heat exchange to the realization dispels the heat to automatically controlled subassembly 200 and compressor 300.

In the utility model, the sound insulation board 400 is obliquely arranged between the compressor cavity and the fan cavity, the air inlet of the case in fig. 1 is taken as a reference surface, one end of the sound insulation board 400 close to the air inlet of the case is a backward end, and the end of the sound insulation board 400 far away from the air inlet of the case is a forward end; the end of the baffle 400 near the front end is bent into a vertical end, a plurality of air outlets 420 are arranged in parallel at the end of the end, and a plurality of air inlets 410 are arranged in parallel at the end of the baffle 400 near the rear end. The limit portion and the quick-witted case 100 wall connection of acoustic celotex board 400, cavity including the formation surrounds automatically controlled subassembly 200 and compressor 300, and acoustic celotex board 400 is separated automatically controlled subassembly 200 and compressor 300 and other parts in quick-witted case 100, lets the air current that is guided by acoustic celotex board 400 can be alone to the cooling of dispelling the heat of automatically controlled subassembly 200 and compressor 300 in this cavity, compares prior art, the utility model discloses can provide better radiating effect for these heating element of automatically controlled subassembly 200 and compressor 300.

The obliquely arranged sound insulation board 400 can guide airflow better and has a waterproof effect; the air flow enters the case 100 from the air inlet of the case 100 at the rear part of the case and then meets the obstruction of the sound-proof board 400, the air flow has the characteristics of flowing along the air duct and filling the space by spreading, the sound-proof board 400 arranged obliquely divides the air flow, as shown in fig. 3, a portion of the air flow flows forward along the baffle 400, and the portion of the air flow dissipates heat from the other side components in the cabinet 100, and another portion of the air flow flows backward along the baffle 400, and the portion of the air flow flows to the air inlet 410 at the rear end of the baffle 400, enters the cavity in front of the baffle 400 from the air inlet 410, heat exchange is carried out with the electric control assembly 200 and the compressor 300 in the cavity, heat around the heating element in the cavity is taken away, as shown in fig. 4, the airflow is exhausted from the cavity through the air outlet 420, and finally exhausted from the air outlet of the chassis in front of the chassis 100, so as to effectively reduce the temperature of the electronic control assembly 200 and the compressor 300.
