Abstract

The utility model relates to a heat crack prevention type heat exchanger, which comprises a core body, an upper sealing head and a lower sealing head, wherein a sealing strip is arranged on the core body and is respectively welded with the upper sealing head and the lower sealing head. The heat exchanger provided by the utility model adopts the sealing strip structure, the fin burning damage in the welding process is avoided, the reliability is improved, and the heat exchange performance influence factors are reduced, the leakage occurrence of products in the use process is prevented, and the safety of the products is improved.

Description

A kind of anti-hot tearing type heat exchanger
Technical field
The utility model belongs to the air compressor chillers technical field, particularly a kind of anti-hot tearing type heat exchanger.
Background technology
At present, after product core body 3 solderings in the heat exchanger were good, directly low head was gone up in welding; Baffle plate 2 is positioned at upper cover one side, baffle plate 2 when welding with upper cover hot-working once, baffle plate 2 during with the low head welding secondary hot-working meeting cause distortion; So simultaneously near core body 3 one side secondary welding, and baffle plate 2 can contact with core body 3 fins when welding with core body 3, causes fin scaling loss (as shown in Figure 1) easily; In addition, in welding process, because of baffle plate is the 0.6-0.8 millimeter usually; Cause heat fatigue easily, leakage problem may appear in the growth along with the working time in the heat exchanger use.
The utility model content
Problems such as the fin scaling loss that causes at heat exchanger head place welding baffle plate up and down to present existing heat exchanger, leakage, the purpose of the utility model is to provide a kind of anti-hot tearing type heat exchanger.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of anti-hot tearing type heat exchanger, comprise core body, upper cover and low head, and it is characterized in that: said core body is provided with strip of paper used for sealing, and said strip of paper used for sealing welds with said upper and lower end socket respectively.
Preferably, said core body and said strip of paper used for sealing are structure as a whole.
Preferably, said strip of paper used for sealing thickness is 9 millimeters.
The beneficial effect of the utility model: adopted the strip of paper used for sealing structure to replace baffle arrangement in the heat exchanger in the utility model, avoided fin scaling loss in welding process, improved reliability, reduced the factor that influences heat exchange property.Prevent that revealing from use appearring in product, improved security of products.
Description of drawings
Fig. 1 is the structural representation of heat exchanger in the prior art;
Fig. 2 is the structural representation of anti-hot tearing type heat exchanger in the utility model;
Among the figure: 1 upper cover, 2 baffle plates, 3 core bodys, 4 strip of paper used for sealings, 5 low heads.
The specific embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
As shown in Figure 2, a kind of anti-hot tearing type heat exchanger comprises core body 3, upper cover 1 and low head 5, and upper cover 1 and low head 5 lay respectively at the two ends up and down of core body 3, and said core body 3 is provided with strip of paper used for sealing 4, and said strip of paper used for sealing 4 welds with said upper and lower end socket respectively.
Core body described in the utility model 3 is structure as a whole with said strip of paper used for sealing 4, causes core body 3 damages when avoiding welding, scaling loss fin and influence the product heat dispersion.
4 thickness of strip of paper used for sealing described in the utility model are 9 millimeters, because thickness is bigger, can ignore by deflection with end socket 1 welding the time for strip of paper used for sealing 4, and the heat fatigue of initiation can restore to the original state.
Embodiment 1: a kind of anti-hot tearing type heat exchanger, comprise core body 3, strip of paper used for sealing 4, upper cover 1 and low head 5, and on core body 3, be provided with several strip of paper used for sealings 4; Strip of paper used for sealing 4 and core body 3 integral braze-welded moulding just can not influence the heat dispersion of product, and strip of paper used for sealing 4 welds respectively with upper cover 1, low head 5; Strip of paper used for sealing 4 thickness are 9 millimeters, because thickness is bigger, can ignore by deflection when welding with upper and lower end socket for strip of paper used for sealing 4 like this; The heat fatigue that causes can restore to the original state, and does not so just have scaling loss fin problem.
In sum; Replaced all baffle plate 2 structures in the original structure with strip of paper used for sealing 4 in the utility model, because the thickness of strip of paper used for sealing is bigger, can ignore by deflection when welding with upper and lower strip of paper used for sealing for strip of paper used for sealing 4; Improve reliability, reduced the factor that influences heat exchange property.Prevent that revealing from use appearring in product, improved security of products.
What should explain at last is: the above is merely the embodiment of explanation the utility model; Be not limited to the utility model; For a person skilled in the art; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.

Claims (3)
