Abstract

The utility model discloses a heat radiator of an automobile, which comprises water chambers, a core of the heat radiator and side plates, wherein the water chambers are arranged at both sides of the longitudinal direction of the core of the heat radiator, the side plates are arranged at both sides of the transverse direction of the core of the heat radiator, the water chambers, the core of the heat radiator and the side plates are formed by soldering, fixing and assembling, and inwards concave pressing grooves are arranged on the end faces of the outer sides of the side plates. Because the side plates and the core of the heat radiator have different structures, different materials and different expansion coefficients, the degrees of expansion and contraction occurring in the side plates and the core of the heat radiator can be asynchronous when the side plates and the core of the heat radiator are subject to the influence of the temperature, so that the positions of the four corners of the core of the heat radiator generate larger stress, and the service life of the heat radiator of the automobile is greatly shortened. Therefore, the stressed pressing grooves for preventing the deformation of the side plates are arranged on the end faces of the outer sides of the side plates in the utility model, which effectively avoids the deformation of the side plates and the core of the heat radiator during soldering, reduces the rejection rate of products during soldering and also prolongs the service life of the heat radiator of the automobile.

Description

Automobile radiators

Technical field

The utility model relates to a kind of automobile radiators, especially a kind of automobile radiators that assembles by soldering.

Background technology

At present, the automobile radiators of known corrugated tube type structure generally fits together radiator core and side plate earlier, carry out soldering again, because be subjected to Temperature Influence, expansion and contraction to a certain extent can take place in radiator core and side plate, but because the difference of the side plate and the different and coefficient of expansion of radiator core different and material structurally, can be asynchronous on expansion that side plate and radiator core take place at temperature influence and the shrinkage degree, side plate both sides and centre position longitudinally particularly, make the corner location of radiator core produce big stress, shortened the service life of automobile radiators greatly.

Summary of the invention

At the deficiencies in the prior art, it is a kind of simple in structure that the utility model provides, the automobile radiators of longer service life.

For achieving the above object, the utility model provides a kind of automobile radiators, comprise hydroecium, radiator core and side plate, hydroecium is located at radiator core both sides longitudinally, side plate is located at the horizontal both sides of radiator core, hydroecium, radiator core and side plate fixedly assemble by soldering, and side plate outside end face is provided with the indent that concaves.

The beneficial effects of the utility model are: because the difference of the side plate and the different and coefficient of expansion of radiator core different and material structurally, expansion that side plate and radiator core are taken place when temperature influence and shrinkage degree can be asynchronous, thereby the corner location that makes radiator core produces big stress, shortened the service life of automobile radiators greatly, so the utility model is provided with the stress indent of anti-side plate distortion on the end face of the side plate outside, effectively avoided the distortion when soldering of side plate and radiator core, reduce the scrappage of product when soldering, and prolonged the service life of automobile radiators.

The utility model can further be set on the end face of the side plate outside vertically, and both sides and centre position are respectively equipped with the indent that concaves.

The specific embodiment

A kind of automobile radiators as shown in Figure 1, 2, comprise hydroecium 1, radiator core 2 and side plate 3, hydroecium 1 is located at radiator core 2 both sides 21 longitudinally, side plate 3 is located at the horizontal both sides 22 of radiator core 2, hydroecium 1, radiator core 2 and side plate 3 fixedly assemble by soldering, and vertically both sides 311 and centre position 312 are respectively equipped with the indent 313 that concaves on side plate 3 outside end faces 31.

Because the difference of the side plate 3 and the different and coefficient of expansion of radiator core 2 different and material structurally, expansion that side plate 3 and radiator core 2 are taken place when temperature influence and shrinkage degree can be asynchronous, thereby the corner location that makes radiator core 2 produces big stress, shortened the service life of automobile radiators greatly, so the utility model is provided with the stress indent 313 of anti-side plate 3 distortion on side plate 3 outside end faces 31, side plate 3 and the distortion of radiator core 2 when soldering have effectively been avoided, reduce the scrappage of product when soldering, and prolonged the service life of automobile radiators.
