Abstract

The utility model relates to heat radiator of internal-combustion engine main leaf, the specifically unstressed main leaf structure of heat radiator of internal-combustion engine, the corner of this main leaf all has otch, and the otch of described main leaf corner is identical, this otch is opened in the corner of main leaf before flange, and ecto-entad is offered; Otch on described main leaf after flange is opening up; Described otch is strip, and the root near main leaf is " V " font.Otch has all been offered in the corner that the utility model is concentrated at main leaf stress, stress relief after main leaf flange, unstressed concentrated, thus efficiently solve the existence of existing main leaf due to stress, main leaf distortion after soldering, planeness is poor, and then causes hydroecium to press-fit difficulty, presses tooth pressing not go up and seal ring mal-compression causes the problems such as leakage; Main leaf structure of the present utility model is simple, and manufacturing efficiency is high.

Description

Main leaf structure that heat radiator of internal-combustion engine is unstressed

Technical field

The utility model relates to heat radiator of internal-combustion engine main leaf, specifically the unstressed main leaf structure of a kind of heat radiator of internal-combustion engine.

Background technique

Radiator is important parts in internal-combustion engine cooling system, if cool bad, leak life-span by directly affecting internal-combustion engine, the fault of the cylinder that even occurs rising; And the pith that main leaf is connected with core body as radiator water chamber, its project organization and accuracy of manufacturing directly have influence on assembly precision and the sealing of radiator.Therefore, the design of main leaf has considerable meaning.

At present, the main leaf structure of plastic-aluminum heat radiator of internal-combustion engine is as shown in Figure 1A, Figure 1B and Fig. 2, and main leaf 1 is inner after overturning process forms closed half chamber 2, and stress concentrates on the corner of main leaf 1 after flange, and namely the corner of main leaf 1 is stress concentrated position 3; Stress cannot discharge, cause main leaf 1 bending deflection, planeness is poor, even if carry out alignment to main leaf 1 after core body assembling, but due to the existence of main leaf 1 four jiaos of stress, after soldering, the planeness of main leaf 1 is undesirable, and then shines into hydroecium and press-fit difficulty, and the situation of shining into leakage with seal ring mal-compression not go up in the pressing of pressure tooth.

Model utility content

In order to solve because of existing main leaf structure cause main leaf to bend, the problem of planeness difference, the purpose of this utility model is to provide a kind of heat radiator of internal-combustion engine unstressed main leaf structure.

The purpose of this utility model is achieved through the following technical solutions:

Main leaf of the present utility model has the otch discharging stress after described main leaf flange.

Wherein: the corner of described main leaf all has otch; The otch (4) of described main leaf corner is identical, and this otch is opened in the corner of main leaf before flange, and ecto-entad is offered; Otch on described main leaf after flange is opening up; Described otch is strip, and the root near main leaf is " V " font.

Advantage of the present utility model and good effect are:

1. otch has all been offered in the corner that the utility model is concentrated at main leaf stress, stress relief after main leaf flange, unstressed concentrated, thus efficiently solve the existence of existing main leaf due to stress, main leaf distortion after soldering, planeness is poor, and then causes hydroecium to press-fit difficulty, presses tooth pressing not go up and seal ring mal-compression causes the problems such as leakage.

2. main leaf structure of the present utility model is simple, and manufacturing efficiency is high.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Fig. 3 A, Fig. 3 B, Fig. 4 and Fig. 5, main leaf structure of the present utility model, main leaf 1 has the otch 4 discharging stress after main leaf 1 flange; Because after main leaf 1 flange, stress concentrates on corner, so the utility model all has otch 4 in the corner of main leaf 1.

The otch 4 that main leaf is 1 four jiaos is formed in main leaf 1 trimming operation.As shown in Fig. 6 A, Fig. 6 B, in the trimming operation of producing main leaf 1, the tooth of otch that main leaf is 1 four jiaos 4 and main leaf 1 together blanking is formed, and carries out flange and punching and then form main leaf structure of the present utility model at lower sequence main leaf 1.As shown in Figure 7, the otch 4 that main leaf is 1 four jiaos is identical, and otch 4 is strip, and the root near main leaf 1 is " V " font; The otch 4 of the present embodiment is wide is 3mm.

Main leaf 1 of the present utility model discharges stress primarily of the otch 4 offered in corner, and the otch 4 of corner is formed in main leaf 1 trimming operation, next overturning process formed as shown in Figure 4, Figure 5 without chip architecture of just advocating.Like this due to the effect of otch 4, after main leaf 1 flange, stress is discharged, and stress is not concentrated, and then ensure that main leaf is straight, there will not be the phenomenon that main leaf plane of bending degree is overproof, avoid and follow-uply press-fit difficulty, the problem of radiator leak because main leaf is in bending photograph the into of stress.
