Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

As shown in fig. 1, a heat dissipation structure for an air conditioner includes a substrate 1. The substrate 1 is in a rectangular flat plate shape, can be made of an aluminum plate, and has a thickness of 30-50 mm. The base plate 1 is provided with a tubular cavity 2 having a three-fold shape inside. The inlet and the outlet of the cavity 2 are arranged on the same side wall of the base plate 1 and are communicated with an air conditioner refrigerant circulation loop through a connecting pipe so as to introduce a refrigerant into the cavity to exchange heat with the base plate. Related electronic components can be mounted on the substrate 1, and efficient heat dissipation is achieved.

The cross section of the inner wall of the cavity 2 is in a sawtooth shape, so that the heat exchange area can be effectively increased. Preferably, the angle of the saw teeth is 40-60 degrees, so that the contact area of the refrigerant and the heat dissipation substrate can be optimized to the maximum.

As shown in fig. 2, the inlet and the outlet are both waist-shaped holes, and a W-shaped protrusion is arranged on a section of each waist-shaped hole, so that the contact area of the flowing refrigerant can be increased, and the pressure drop of the system caused by the flowing refrigerant entering the cavity in the flowing process can be reduced. Preferably, the included angle Y of the protrusions is 60-90 degrees. The width Z1 of the inlet or outlet is determined by the size of the heat exchange line connected to the base plate, and is generally 9.52/12.7/16 cm.

The connecting pipe comprises a front section 3 pipe and a rear section 4 pipe. The front end pipe 3 is connected with the inlet or the outlet, and the rear end pipe 4 is connected with an air conditioner refrigerant circulation loop. The front section pipe 3 is made of an aluminum pipe, and the heat conducting performance of the front section pipe can be further improved. The rear-section pipe 4 is made of a copper pipe and can be conveniently welded with other copper pipes in the whole machine. The front section pipe 3 and the rear section pipe 4 can be connected through brazing, so that the front section pipe and the rear section pipe are firmly connected.

The utility model discloses an inside curved tubulose cavity structure that sets up of base plate itself to establish the surface of cavity into the cockscomb structure, make the flow of system refrigerant can directly maximize in the base plate, effectively increased heat transfer area, improved heat exchange efficiency.
