Abstract

The utility model discloses a kind of new type heat exchangers with bypass pipe structure, including bypass pipe, by-passing valve, stress slot；The bypass pipe is set to core centre position；The bypass pipe both ends are connected with the oil guide pipe of heat exchanger body both sides respectively；The by-passing valve is mounted on bypass pipe；Two outsides of the core are equipped with side plate；Stress slot is cut on the side plate.By bypass pipe setting in heat exchanger core body centre position, stress slot can be cut in core both sides, be released effectively thermal stress.Meanwhile the fin adjacent with its both sides is inner fin, can be faster transmitted on adjacent channel by the deep fat of bypass pipe, also core oil temperature can be made to be more evenly distributed, the temperature difference between core is caused to reduce, and to reduce thermal stress, shortens " defrosting " time.

Description

A kind of new type heat exchanger with bypass pipe structure

Technical field：

The utility model is related to design of heat exchanger construction applications, more particularly to a kind of novel heat exchange with bypass pipe structure Device.

Background technology：

After heat-exchange system does not work for a long time under low temperature environment (such as -30 DEG C), heat exchanger " is freezed ", and inside is caused The oil viscosity of storage is very big, and heat exchanger inner passage is made to be in " blocking " state.After system restarts, deep fat, which enters, to be changed Hot device core, because inner passage is in " blocking " state, fluid can not be successfully flow to heat exchanger exit by inner passage, leads Heat exchanger internal pressure is caused to increase, the subsequent parts of heat exchanger core body pass through without fluid, especially when for lubricating, can cause System oil starvation and damage system.Therefore, it is necessary to which by-passing valve and relief tube are arranged on heat exchanger core body, when cold-starting inside When the oil viscosity in channel is higher to be flowed, deep fat carries out bypass and pressure release by bypass pipe, avoids " plug cock " and core pressure Power raising causes core to rupture.

Original heat exchanger with bypass pipe structure, bypass pipe are generally located on the end socket terminal location of heat exchanger side.By It is in heat exchanger side in the position of its arrangement, causes bypass pipe side that can not cut stress slot.Oil inlet, oil inlet end socket, bypass Pipe etc. temperature is higher, and other spot temperatures of core are relatively low, thus generate the larger temperature difference, so as to cause heat exchanger generate compared with Big thermal stress.Since bypass pipe side can not cut stress slot, causes thermal stress to be unable to get and be released effectively.Therefore, it is easy to lead It causes heat exchanger core body to destroy and fail (oil leak), reduces the service life of heat exchanger.Further, since the other bypass pipe set, and it is other The siphunculus generally outer fin adjacent with core, causes the fluid that heat exchanger inner passage freezes to need the long period could " solution Freeze ", make the higher pressure of bearing of heat exchanger core body long period, increase system pressure, reduces drive system efficiency, it also can be The heat exchanger service life is influenced to a certain extent.

The information for being disclosed in the background technology part is merely intended to increase the understanding to the general background of the utility model, and It is not construed as recognizing or implying in any form that information composition has been existing well known to persons skilled in the art Technology.

Utility model content：

It is above-mentioned existing to overcome the purpose of this utility model is to provide a kind of new type heat exchanger with bypass pipe structure There is the defects of technology.

To achieve the above object, the utility model provides a kind of new type heat exchanger with bypass pipe structure, including sets Core inside heat exchanger body and the oil guide pipe set on heat exchanger body both sides further include：Bypass pipe, by-passing valve, Stress slot；The bypass pipe is set to core centre position；The bypass pipe both ends oil guide pipe with heat exchanger body both sides respectively It is connected；The by-passing valve is mounted on bypass pipe；Two outsides of the core are equipped with side plate；It is cut with and answers on the side plate Power slot.

Preferably, in technical solution, the oil guide pipe is equipped with oil inlet and oil outlet.

Preferably, in technical solution, the length of the bypass pipe and the equal length of core.

Compared with prior art, the utility model has the advantages that：

Bypass pipe is arranged in heat exchanger core body centre position heat exchanger provided by the utility model, can be in core both sides Stress slot is cut, thermal stress is released effectively.Meanwhile the fin adjacent with its both sides is inner fin, passes through the deep fat energy of bypass pipe It is transmitted to faster on adjacent channel, also core oil temperature can be made to be more evenly distributed, cause the temperature difference between core to reduce, to drop Low thermal stress shortens " defrosting " time.

Description of the drawings：

Fig. 1 is a kind of structural schematic diagram of the new type heat exchanger with bypass pipe structure of the utility model；

Reference numeral is：1- cores, 2- bypass pipes, 3- by-passing valves, 4- side plates, 5- stress slot, 6- oil guide pipes, 7- oil inlets Mouth, 8- oil outlets.

Specific implementation mode：

Specific embodiment of the present utility model is described in detail below, it is to be understood that the protection of the utility model Range is not restricted by specific implementation.

Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " comprising " or its change It changes such as "comprising" or " including " etc. and will be understood to comprise stated element or component, and do not exclude other members Part or other component parts.

As shown in Figure 1, a kind of new type heat exchanger with bypass pipe structure, includes the core inside heat exchanger body 1 and the oil guide pipe 6 set on heat exchanger body both sides, further include：Bypass pipe 2, by-passing valve 3, stress slot 5；The bypass pipe 2 Set on 1 centre position of core；2 both ends of the bypass pipe are connected with the oil guide pipe of heat exchanger body both sides 6 respectively；The bypass Valve 3 is mounted on bypass pipe 2；Two outsides of the core 1 are equipped with side plate 4；Stress slot 5 is cut on the side plate 4.It is described Oil guide pipe 6 is equipped with oil inlet 7 and oil outlet 8；The equal length of the length and core 1 of the bypass pipe 2.

Deep fat enters bypass pipe 2 from oil inlet 4, through oil guide pipe 6, and by-passing valve 3 controls fluid and is discharged from oil outlet 8.Due to The fin of 2 adjacent both sides of bypass pipe is inner fin, and the deep fat of bypass pipe 2 can be rapidly transferred on adjacent channel, make core 1 Oil temperature distribution it is more uniform, improve core 1 service life；Cutting stress slot 5, works as deep fat on the side plate 4 in 1 outside of core Into fashionable, the temperature of oil inlet 4 and bypass pipe 2 etc. is higher, and the temperature of core 1 is relatively low at this time, thus generates larger The temperature difference, larger thermal stress is generated so as to cause heat exchanger, stress slot 5 can be released effectively thermal stress.

The description of the aforementioned specific exemplary embodiment to the utility model is in order to illustrate and illustration purpose.These Description is not wishing to for the utility model to be limited to disclosed precise forms, and it will be apparent that according to the above instruction, can carry out Many change and variations.The purpose of selecting and describing the exemplary embodiment is that explaining the specific principle of the utility model And its practical application, so that those skilled in the art can realize and utilize a variety of different examples of the utility model Property embodiment and various chooses and changes.The scope of the utility model is intended to by claims and its waits similar shapes Formula is limited.
