Description
Technical field
A kind of small micro-channel heat exchanger and heat-exchange method are the utility model is related to, belongs to the energy-conservation loss of weight synergy of heat exchanger
Technical field.
Background technology
At present, the application of heat exchanger is more and more extensive, but the volume of many occasion heat exchangers is larger, and weight is larger, consumption
Material is more, is not easy to install.Using more for shell-and-tube heat exchanger, but the heat exchange efficiency of shell-and-tube heat exchanger is relatively low, into
This is high.
Existing tubular heat exchanger, collector are cylinder, and section is round, and tube bank is laterally inserted directly into, because insertion outer rim is
Circular arc, cause every pipe and the resistance that the intersection of collector is different space curves, welding difficulty, and the import of pipe special
Property it is different, it is difficult to accomplish that shunting is uniform, every tube length is inconsistent in addition, and the overall efficiency of heat exchanging device has a great influence.
Existing improvement tubular heat exchanger, it is semicircular cylinder to cut pipe, and section is D types, restrains the line part in laterally inserted D types section
Point, solve the equal problem of tube length substantially, due to on-circular cross-section, intensity, the rigidity in section are very poor, only increase and cut pipe
Wall thickness, this is particularly disadvantageous to reducing heat exchanger weight, and due to the deformation of stress concentration and its issuable coupling part, pipe
The straight line portion that beam need to cross D types section has certain depth to be welded and fixed, and this has a negative impact to shunting.
The unrestraint ability in addition, existing tubular heat exchanger without balance shock mechanism, is pulsed to caused by dynamic change, and
Pulsation can cause to shunt uneven deterioration heat-transfer effect.
Utility model content
The purpose of this utility model is to provide a kind of small micro-channel heat exchanger compact-sized, heat exchange efficiency is high, energy consumption is low.
A kind of small micro-channel heat exchanger, including heat-exchanging tube bundle, one collector of each UNICOM of upper/lower terminal of heat-exchanging tube bundle, collection
It is circle to manage as horizontal tubular, its longitudinal section;One of collector is provided with header inlet, and another collector is provided with collector and gone out
Mouthful;It is characterized in that:Horizontal baffle is set in collector, and collector is divided into two chambers up and down by the horizontal baffle, wherein close to heat exchange
Tube bank for balance shock chamber, away from heat-exchanging tube bundle to flow chamber;Horizontal baffle is provided with tube bank mounting hole, and heat-exchanging tube bundle is worn
Cross after collector wall and balance shock chamber and be connected with horizontal baffle at tube bank mounting hole, and by restraining mounting hole with flowing
Chamber UNICOM;Horizontal baffle is additionally provided with the balance pipe for making balance shock chamber and Jun Liu chambers UNICOM.
The heat-exchange method of described small micro-channel heat exchanger, it is characterised in that:The heat transfer process passage of intraductal working medium is as follows:
Intraductal working medium enters collector by header inlet, and heat-exchanging tube bundle is flowed into after shunting, after carrying out heat exchange with working medium outside pipe, flows into collection
Pipe, by manifold outlet ports outflow heat exchanger;Balance pipe is for offsetting, arteries and veins caused by buffer fluid flow instabilities or outside exciting
It is dynamic;The heat transfer process passage of the outer working medium of pipe is as follows:Outer horizontal plunder of working medium of pipe washes away heat-exchanging tube bundle, foundation be actually needed as cold side or
Hot side absorbs or released the heat of intraductal working medium, completes diabatic process.
Dividing plate can use the modes such as tube expansion or welding to mechanically connect with tube bank, tube bank and collector, and balance pipe is set on dividing plate
Pulsed for offsetting, caused by buffer fluid flow instabilities or outside exciting.Fluid working substance enters upper header by header inlet
Inside flow chamber, flow to passage aisle tube bank, with tube bank outer fluid heat exchange, into lower collector pipe in flow chamber, flowed out by manifold outlet ports.
For the utility model by using the design of two collectors and its inside, every heat exchanger tube and collector and its dividing plate are dual
Connection, enhance the bonding strength of tube bank, it is important that the every small microchannel of tube bank is isometric and conformity, stream chamber cause
Shunting is uniform, and overall heat exchange effect is significant, and restrains isometric design and make it that the pressure drop of heat transfer process is consistent, further
The uniform process of shunting is enhanced, integrates pipe shell as tubular so that voltage endurance capability increases substantially, and the wall thickness of collector can greatly drop
Low, this volume miniaturization, lightweight to small micro-channel heat exchanger, the cost for reducing heat exchanger plays an important roll.
Described heat-exchanging tube bundle is multipaths.
Described heat-exchanging tube bundle is metal or non-metallic material.
Described heat-exchanging tube bundle is that multilayer fork is arranged or the diameter of in-line arrangement forms less than 3mm passage aisles pipe.

Embodiment
Such as Fig. 1, as shown in Figure 2 and Figure 3, the heat transfer process passage of intraductal working medium 6 is as follows:Intraductal working medium 6 is by header inlet 1
Into upper header, heat-exchanging tube bundle 4 is flowed into after shunting, after carrying out heat exchange with working medium outside pipe 7, lower collector pipe is flowed into, by manifold outlet ports 5
Outflow heat exchanger;The heat transfer process passage of the outer working medium 7 of pipe is as follows:Outer horizontal plunder of working medium 7 of pipe washes away heat-exchanging tube bundle 3, is needed according to actual
Will as it is cold while or it is hot while absorb or release the heats of 7 intraductal working mediums 6, complete diabatic process.
The architectural feature and efficiency that the heat transfer process of intraductal working medium 6 needs are ensured by the design of collector:Collector is by section
Metal or non-metal shell, the built-in horizontal baffle 10 of pipe form, wherein upper and lower collector is made provided with collector import and export 1,5
To be imported and exported for intraductal working medium, heat-exchanging tube bundle is connected by way of welding or tube expansion between the two through pipe shell 8 is collected,
Collector is divided into by horizontal baffle 10 flows chamber 9 and balance shock chamber 11, is realized by the balance pipe 12 on horizontal baffle between two chambers
Pressure balance, the end plate as heat-exchanging tube bundle 3 simultaneously of horizontal baffle 10, be fixedly connected with heat-exchanging tube bundle 3.
By using the design of two collectors and its inside, every heat exchanger tube and collector and its dual connection of dividing plate, enhancing
The bonding strength of tube bank, it is important that the every small microchannel of tube bank is isometric and conformity, flows chamber and make it that shunting is uniform,
Overall heat exchange effect is significant, isometric design is restrained and make it that the pressure drop of heat transfer process is consistent, further enhance point
Uniform process is flowed, collection pipe shell is circle so that voltage endurance capability is increased substantially, and the wall thickness of collector can be reduced greatly, and this is right
Volume miniaturization, the lightweight of small micro-channel heat exchanger, the cost for reducing heat exchanger play an important roll
In a word, a variety of requirements after the intensive heat exchanger small macro of small micro-channel heat exchanger, enhance unit area(Unit
Volume, weight)Exchange capability of heat, in the case of identical heat exchange amount, heat exchange area(Volume, weight)It can reduce, so as to drop
The cost of low heat exchanger.The raising of heat exchange efficiency, make the heat exchange of therrmodynamic system more abundant, reach so as to reduce the power consumption of system
The purpose of energy-saving and emission-reduction.
