Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
As shown in figure 1, the embodiment of the present invention includes the heat exchanger main body with the heat exchanging chamber for accommodating the material that need to exchange heat
1, the inlet 2 and liquid outlet 3 connected with heat exchanging chamber is provided with heat exchanger main body 1, it is characterised in that：In heat exchanger main body 1
Be provided with it is multiple be used for disturb liquid carry out linear flow turbulent flow barrier point 4 by heat exchanging chamber be divided into it is multiple be connected be used for
Increase the surface area of heat exchanger main body 1, while the inclusion 5 of main place is provided for turbulent flow, shape between two neighboring turbulent flow barrier point 4
Into the runner 6 for connecting inclusion 5.Connected between any two inclusion 5 by least one runner 6, the runner 6 becomes
The main thoroughfare of liquid drain.The sectional area of inclusion 5 is more than the sectional area of runner 6.Each positive other side of inclusion 5 is respectively provided with upwards
There is at least one turbulent flow barrier point 4, be just both that inclusion 5 is in vertical direction when heat exchanger main body 1 is in running order to direction
Two relative directions and two relative directions in a parallel direction, this four direction is the Main way of liquid flowing,
Set turbulent flow barrier point 4 effectively to hinder the flowing of liquid on this four direction, reach the purpose of turbulent flow.Such as Fig. 5 institutes
Show, the heat exchanger scheme of prior art is laminar flow scheme, carried out along a linear direction when being both liquid communication,
This kind of mode heat transfer efficiency is poor, and fluid point liquid is uneven, and there is dead band in water route.This form pressure-bearing is than relatively low, while this side
Formula needs to carry out by heat pipe 7, and there is a diabatic process between heat pipe 7 and the heat exchange housing 8 of outside, and this can serious shadow
Ring the efficiency of actual heat exchange.
In the heat exchanger main body 1 of the embodiment of the present invention at least have one by least three mutually equidistantly arrange it is adjacent
Turbulent flow barrier point 4, which encloses, is provided with an inclusion 5 in the turbulent structure to be formed, turbulent structure, be both at least to have one group by three
Turbulent flow obstructs the turbulent structure for the ORTHOGONAL TRIANGULAR shape that point 4 is surrounded at equal intervals mutually, while the formation of turbulent structure can extend
Five surrounded to the square or rectangular structure surrounded by four turbulent flow barrier points 4, by five turbulent flow barrier points 4
Correspondence is only provided with an inclusion 5 in angle star structure etc., but each turbulent structure.Further optimization is then turbulent flow barrier point 4
It is distributed in the way of the array that misplaces in heat exchanger main body 1.Both as shown in figure 1, same row and with a line turbulent flow barrier point 4
It is intervally arranged.The setting causes turbulent flow barrier point 4 to form ORTHOGONAL TRIANGULAR shape staggered row in heat exchanger main body 1
Row, as shown in figure 3, continuing when liquid enters from A directions after inclusion 5 toward when linear direction flowing, liquid can be by turbulent flow resistance
Dot interlace 4 stops, causes liquid to carry out turbulent condition heat transfer centered on turbulent flow barrier point 4 as identified in Fig. 2, now
Liquid makes irregular movement, mutual blending, the tortuous chaotic form in track and form heat transfer in inclusion 5, due to turbulent flow biography
Pass heat speed is long-range and layer flow mode, this make it that the actual heat-transfer effect of the present invention is substantially improved, and due to the present invention
Middle turbulent flow barrier point 4 is that ORTHOGONAL TRIANGULAR shape is staggered, array, so turbulent flow is to exist in heat exchanger main body 1 everywhere
, so the significantly lifting that the overall heat exchange effect of the heat exchanger main body 1 of the present invention is obtained.Relatively of the invention is turbulent without guiding
The heat exchange of formula, heat exchange efficiency much deficiencies of the guidance mode for the linear flow that prior art is used.
Heat exchanger main body 1 includes two structure plates, and two structure plates are obstructed in heat exchanging chamber correspondence position at least through turbulent flow
The progress of point 4 is affixed, and disconnected from each other heave in part without turbulent flow barrier point 4 to form inclusion 5 and runner 6.
As shown in figure 4, when the tiling area of heat exchanger main body 1 is excessive, liquid is entered after heat exchanging chamber and flowed to
In mix the cycle efficieny for causing heat-exchanger rig overall it is too low when, the present invention is provided with heat exchanger main body 1 for hindering
Liquid is kept off along the barrier rib 9 for continuing flowing when front direction, heat exchanging chamber is at least divided into the backflow of two unidirectional UNICOMs by barrier rib 9
Portion, so allows for liquid with better flow tendency, so as to lift the circulation of the excessive heat exchanger main body 1 of tiling area
Efficiency.
The embodiment of the method for the present invention comprises the following steps：
Step one, blanking, cuts the big steel version of two pieces of grades as structure board raw material, and do the cleaning on basis simultaneously；
Step 2, shaping carries out flatness shaping to hook version；
Step 3, cavity forming is staggered relatively by two structure plates, and the edge of two structure plates is entered under vacuum conditions
Two structure plates are merged into heat exchanger main body 1, and form heat exchanging chamber by row laser welding；
Step 4, inlet tube, outlet welding, installs inlet tube and outlet, and reinforcement of weld additional on heat exchanging chamber；
Step 5, turbulent flow barrier point 4 is molded, and heat exchanging chamber is carried out two block structures at laser spot welding, spot welding under vacuum conditions
Plate weld connection is to form turbulent flow barrier point 4, and the connection that so turbulent barrier point 4 both can be used for reinforcing two structure plates is strong
Degree, has disperseed pressure of the internal pressure to each tie point of heat exchanging chamber, while serving the effect of turbulent flow again；
Step 6, pressurising rise bag, heat exchanging chamber carry out punching press and make on heat exchange cavity except turbulent flow barrier point 4 in addition to demi-inflation shape
Become to form inclusion 5 and runner 6；
Step 7, secondary reshaping, heat exchanging device main body 1 carries out smooth shaping again；
Step 8, surface treatment, the surface of heat exchanging device main body 1 cleaned, the conventional treatment such as anti-oxidation.
Wherein in 4 forming steps of turbulent flow barrier point, heat exchanging chamber carries out entering in the way of the array that misplaces under vacuum conditions
Row laser spot welding.
When the tiling area of heat exchanger main body 1 is excessive, also it is molded in step 3 or step 5 including barrier rib 9,
Heat exchanging chamber carries out carrying out the linear welding of laser in the way of the array that misplaces under vacuum conditions being formed for barrier liquid edge
When front direction continues the barrier rib 9 of flowing, the specific length and shape of barrier rib 9 are formulated according to actual product specification demands.
This specific embodiment is only explanation of the invention, and it is not limitation of the present invention, people in the art
Member can make the modification without creative contribution to the present embodiment as needed after this specification is read, but as long as at this
All protected in the right of invention by Patent Law.
