Description

Automobile air conditioner electric control unit with waterproof function

Technical Field

The utility model relates to an electric control unit structure, in particular to an automobile air conditioner electric control unit with waterproof function,

so as to meet the assembly requirement of the whole vehicle and ensure the service life of the product.

Background

The design mode of an electric control unit of an automobile air conditioner in the existing market is as follows: the assembly position and the assembly relation of the product in the whole warm air system can be confirmed, an evaporator in the warm air system generates condensed water in a working project, the condensed water passes through a gap between an electric control unit heat dissipation device and a shell and is very easy to contact a circuit board, and the circuit board and elements on the circuit board are corroded and rusted or even short-circuited, so that the circuit board is directly burnt out, and the service life of the product is influenced; the adoption is with the MOS pipe clamp between nylon locating piece and fin, and when the MOS temperature exceeded the uniform temperature, the nylon locating piece took place deformation, leads to the MOS pipe can't be with the fin flush mounting, and direct influence MOS pipe heat dissipation, MOS pipe work is in high temperature state often, very easily causes the MOS pipe to damage, leads to the control unit function to become invalid.

Disclosure of Invention

In order to solve waterproof problem of vehicle air conditioner electrical unit and MOS pipe heat dissipation problem among the prior art, the utility model provides a vehicle air conditioner electrical unit with waterproof function.

Therefore, the technical scheme of the utility model is that: the utility model provides an automatically controlled unit of vehicle air conditioner with waterproof function, includes shell, circuit board, MOS pipe, fin, its characterized in that: the MOS tube is directly fixed on the inner side radiating surface of the radiating fin by using a first screw, connecting columns are fixed on two sides of the inner side radiating surface of the radiating fin, the circuit board is fixed on the connecting columns by using second screws, and pins of the MOS tube are connected on the circuit board in a soldering manner;

the inner cavity opening of the shell is provided with a positioning step, the bottom of the positioning step is provided with a plurality of convex isolation ribs, a waterproof gasket is placed in the positioning step, and the positioning part of the radiating fin is placed in the positioning step, pressed on the waterproof gasket and fixed on the shell through a connecting screw.

The technical scheme is further limited as follows: the number of the isolation ribs is 2, the isolation ribs are in the shape of semicircular arc-shaped protrusions, the radius of each semicircular arc-shaped protrusion is 2-3 mm, and the distance between the two isolation ribs is 8-9 mm; the arrangement is simple in structure and easy to implement.

The utility model has the advantages that: because the opening of the inner cavity of the shell is provided with the isolation rib of the positioning step, the evaporator condensate water can be isolated, the evaporator condensate water can not enter the product, and the waterproof function is realized; the MOS tube is directly fixed on the radiating surface of the radiating fin, so that the MOS tube is fully contacted with the radiating fin, and the MOS tube is ensured to have a good radiating effect.
