Abstract

The invention is applicable for the field of a speed-regulating resistor, and provides a chip module portion of the speed-regulating resistor of an automobile air conditioner and the speed-regulating resistor. The chip module portion comprises a bracket, two resistor chips and a radiating block; the section of the bracket along the direction which is parallel with the front and back sides is inversely U-shaped; the two resistor chips are located at the interior of the bracket and are parallel with the left and right sides of the bracket; the upper ends of the two resistor chips are connected transversely; and the radiating block is located between the two resistor chips and is in contact with the inner side faces of the two resistor chips. The resistor chips adopts a siamesed design mod, and matches with the U-shaped bracket and the radiating device to divide heat of a product into two portions; the windward side of each resistor chip comprises a front side, a backside and two contact surfaces in contact with the radiating device, so that the heat radiation efficiency of the product is extremely high; and the chip module portion satisfies the characteristics of small volume, high heat radiation efficiency and the like, can satisfy installation of different customers and heat radiation of products with different powers, and realizes modular design.

Description

technical field [0001] The invention belongs to the field of speed-regulating resistors, in particular to a speed-regulating resistor for an automobile air conditioner. Background technique [0002] Existing automotive air-conditioning speed-regulating resistors are designed in different shapes according to different product requirements, with complex structures and various process methods. [0003] For example, in the technical solution disclosed under the name "Automotive Air Conditioning Speed ​​Regulating Resistor" (Application No.: 201320514105.X), the resistor sheet is sandwiched between two insulating sheets, and the cover plate and the aluminum radiator combine the assembled insulating sheet and The combination of resistor sheets is clamped and installed on the base, and the resistor sheets are connected with pins installed on the base. [0004] Resistors with different resistance values ​​require different numbers of resistors and heat dissipation. Therefore, it is...
