Abstract
The invention discloses a hot cracking prevention heat exchanger, which comprises a heat exchanger core, a cover plate and an end enclosure, wherein the cover plate of the heat exchanger is provided with notches, and each notch is positioned on the left right and the right side of the cover plate respectively. The heat exchanger has the advantages that: the cover plate on two sides of the core of the heat exchanger is provided with the notches, so product failure caused by oil and gas leakage due to tearing at the weak part of the heat exchanger in thermal expansion is avoided, the possibility that the heat exchanger is torn due to thermal expansion is lightened, the service life is prolonged, and the reliability is improved.
Description
Technical field
The present invention relates to a kind of heat exchanger, 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.
Summary of the invention
In order to address the above problem, the invention provides a kind of anti-hot tearing type heat exchanger, because of causing the heat exchanger weakness, thermal expansion tears avoiding, and cause oil gas to leak and cause the phenomenon of product failure to take place.
Technical scheme of the present invention 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 notch, and described notch is positioned at the left and right sides of cover plate, and respectively has one.
Beneficial effect of the present invention is: by the core body two side cover plate place otch 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 heat exchanger expanded by heating of the present invention;
Fig. 2 is the structural representation of existing heat exchanger expanded by heating.
The specific embodiment
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.
As shown in Figure 1, a kind of anti-hot tearing type heat exchanger comprises heat exchanger core body, cover plate and end socket, and the cover plate of described heat exchanger is provided with notch, and described notch is positioned at the left and right sides of cover plate, and respectively has one.
As shown in Figure 2, expand after existing heat exchanger is heated, form drum type at the two ends end socket.
It should be noted that at last: the above only is the preferred embodiments of the present invention, be not limited to the present invention, although the present invention 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.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (2)
