Abstract

A hot-crack proof heat exchanger comprises a heat exchanger core, a cover plate and a seal head, wherein the cover plate of the heat exchanger is provided with more than two through grooves which are arranged on the cover plate in parallel. The hot-crack proof heat exchanger has advantages as follows: as the through grooves are arranged on the cover plate on two sides of the heat exchanger core, product failure caused by oil gas leakage in the condition that the thin part of heat exchanger is torn due to thermal expansion is avoided, the possibility of tearing heat exchanger due to thermal expansion is reduced, service life and reliability are improved.

Description

A kind of anti-hot tearing type heat exchanger
Technical field
The utility model relates to a kind of heat exchanger, and specifically a kind of anti-hot tearing type heat exchanger belongs to the air compressor chillers field.
Background technology
Large-scale screw-rod air compressor air compressor can produce very high temperature in the course of the work, usually to reach 80-200 ℃, of long duration also can reach higher temperature, therefore, for the security consideration of equipment, usually need transmit heat by heat exchanger, yet the end socket at two ends can form drum type during present heat exchanger expanded by heating, and deformation extent is inhomogeneous, end socket centre position deflection maximum, heat exchanger can produce the phenomenon that the heat exchanger weakness is torn through long-time use.
The utility model content
In order to address the above problem, the utility model provides a kind of anti-hot tearing type heat exchanger, tears because of thermal expansion causes the heat exchanger weakness avoiding, and causes oil gas to leak and causes the phenomenon of product failure to take place.
The technical solution of the utility model is: a kind of anti-hot tearing type heat exchanger, comprise heat exchanger core body, cover plate and end socket, and the cover plate of described heat exchanger is provided with groove, and described groove has more than two, and is arranged in parallel on the cover board.
The beneficial effects of the utility model are: open groove by the core body two side cover plate places at heat exchanger, the phenomenon of having avoided causing the heat exchanger weakness to tear, cause oil gas to leak to cause product failure because of thermal expansion takes place, alleviate the possibility of tearing heat exchanger because of thermal expansion, improved service life and reliability.
Description of drawings
Fig. 1 is the structural representation of the utility model heat exchanger expanded by heating;
Fig. 2 is the structural representation of existing heat exchanger expanded by heating.
The specific embodiment
Below preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, a kind of anti-hot tearing type heat exchanger comprises heat exchanger core body 1, cover plate 2 and end socket 3, and the cover plate 2 of described heat exchanger is provided with groove 4, and described groove 4 has more than two, and is arranged in parallel within on the cover plate 2.
As shown in Figure 2, expand after existing heat exchanger is heated, form drum types at two ends end socket 3.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.

Claims (2)
