Automotive radiator high in firmness and low in leakage rate

Abstract

The invention relates to an automotive radiator high in firmness and low in leakage rate. The automotive radiator comprises a water chamber (1), a main sheet (3), a radiating tube (4) and side plates (6). The main sheet (3) is connected with the water chamber (1), the radiating tube (4) and the side plates (6). The side plates (6) are provided with corresponding threaded mounting holes (61). Compared with the prior art, the side plates are provided with the corresponding threaded mounting holes, a fan can be installed directly, an original support structure is omitted, there is no need to manually rivet a support onto the side plates, and therefore the loosening hidden danger in riveting is eliminated, and the reject rate of radiator products is greatly lowered; only a set of mold is required for one-time forming, and thus mold cost and manual riveting cost are reduced; and one face of a radiating tube sealing gasket makes contact with the main sheet and is provided with convex ribs, the contact sealing effect is good and the leakage rate is low.

Description

technical field [0001] The invention relates to an automobile radiator, in particular to an automobile radiator with high firmness and low leakage rate. Background technique [0002] The car radiator is an important key component of the car cooling system. It is composed of a water chamber, a gasket, a main piece, a heat dissipation pipe, a heat sink, a side plate, and a bracket 8. The main piece is connected with the heat dissipation pipe and the water chamber respectively, such as image 3 , Figure 4 As shown, the side plate has a bracket 8, and there are threaded holes for installing a cooling fan on the bracket 8. The bracket 8 and the side plate are connected by rivets 9, which need to be riveted manually. [0003] During the production and use of radiators, there are problems as follows: [0004] 1. The side panels and brackets are produced by two sets of molds, which are costly; [0005] 2. The side panels and brackets are riveted, which requires manual rivets, res...

AI Technical Summary

Problems solved by technology

[0004] 1. The side panels and brackets are produced by two sets of molds, which are costly;

[0005] 2. The side panels and brackets are riveted, which requires manual rivets, resulting in low productivity and high labor costs;

[0006] 3. After riveting the side plate and the bracket, it is easy to deform and the quality is unstable, so it is necessary to increase the calibration process and increase the cost;
