Description
Technical field
The utility model relates to the technical fields of heat exchanger, and in particular to a kind of high temperature impact resistance heat exchanger.
Background technique
Heat exchanger is the equipment that the partial heat of hot fluid is passed to cold fluid, also known as heat exchanger.Heat exchanger is in core
It is widely used in industry, chemical industry, petroleum, power, food and other many industrial productions.
Two or more composition metal is used for the manufacture of heat exchanger, the excellent of two kinds of metals can be given full play to
Point avoids respective disadvantage.For example, making heat exchanger with chromium-zirconium-copper and the composite plate of stainless steel, chromium-zirconium-copper has good conduction
Property, thermal conductivity, hardness is high, wear-resisting antiknock, and crack resistance and softening temperature are high.Stainless steel itself has corrosion resistance and good, can
The features such as weldability, stainless steel is still able to maintain its excellent physical mechanical property at high temperature.The two is combined, Ke Yichong
Distribute the good heat conductive electric conductivity for waving copper and the good intensity of stainless steel and solderability.
Currently, existing high temperature resistant heat exchanger structure is huge, the linking of changeover portion is unreasonable, and part heat pipe is caused to be in not
Work and abnormal operating state.It is easy to crack after bearing high temperature and pressure, thermal (temperature difference) stress is excessive to be also easy to produce deformation, affects
The normal use of heat exchanger, service life is short, and input cost is high.For this case, we are using explosive clad plate production one
The high temperature impact resistance heat exchanger in kind U shape channel.This U-shaped channel can overcome disadvantage mentioned above from structure, make the heat exchange
Device bears the impact of high temperature and pressure, and difficult deformation, cost is relatively low, long service life.
In the document published, patent, in data, not yet finds and changed by the high temperature impact resistance heat of this method production
Hot device.
Summary of the invention
The utility model proposes a kind of high temperature impact resistance heat exchangers.Heat exchanger, composite material benefit are made using composite material
It is made of explosion composite method, substrate uses stainless steel, and compound plate uses chromium-zirconium-copper.Never by chromium-zirconium-copper-stainless steel explosive clad plate
Become rusty steel face fluting, and depth is opened to chromium-zirconium-copper, makes the interface of slot arrival or leap stainless steel and chromium-zirconium-copper then will be with groove width
It spends that comparable curved stainless steel pipe (plate) is outstanding to be placed in slot, forms prefabricated heat transfer path, certain distance is stayed on channel, then uses heap
The method of weldering flat, sealing by channel weldering, to form the channel of heat exchanger.
In order to realize the above-mentioned purpose of the utility model, the utility model provides the following technical solution:
A kind of high temperature impact resistance heat exchanger, including substrate, cladding plate, fluid inlet, fluid outlet, heat transfer path, substrate and
Cladding plate is composite plate, and heat transfer path is conducting heat in the side of substrate or cladding plate, fluid inlet in heat transfer path side, fluid outlet
The channel other side.
The composite plate is explosive clad plate, and substrate is not limited to stainless steel, and cladding plate is not limited to chromium-zirconium-copper.
Compared with prior art, the characteristics of the utility model is had is:
(1) unique arcuate channels are used, have dispersed the high temperature high fever impact force in heat exchanging holes, so that heat exchanger channels is strong
Degree and leakproofness are guaranteed.
(2) the utility model makes composite plate using Explosion composite, and the material and size of metal plate are unrestricted.It is physical
Preferable compound, bond strength height can be achieved in the metal plate and large-area metal plate that can be differed greatly.
(3) utilize side metal solderability, from can the face of weld open longitudinal slot, the size of heat exchanger is unrestricted, processing side
Just, simple and easy.
(4) built-up welding is conventional method, and Technical comparing is mature, and weld strength can guarantee that save the cost is simple and easy.

Specific embodiment
The present invention will be further described in detail with reference to the embodiments and the accompanying drawings, but the implementation of the utility model
Mode is without being limited thereto.
Embodiment 1:
The utility model discloses a kind of high temperature impact resistance heat exchangers, comprising: substrate 1, cladding plate 2, fluid inlet 9, fluid
Export 10, heat transfer path 12.As shown in figure 3, substrate 1 and cladding plate 2 form explosive clad plate by Explosion composite.Heat transfer path
12 in the side of substrate (or cladding plate).It slots on substrate (or cladding plate), so that groove depth is arrived at or cross over composite plate interface, formed
Open groove-type channel.The shape of slot can be the shapes such as rectangular, hole shape.It will be with the comparable arch stainless steel tube (plate) of groove width
