The utility model discloses can increase return -air heat exchanger heat transfer area, improve heat exchange efficiency, reduce heat transfer segment length and reduce energy consumption.
Description
Technical field
The utility model is related to technical field of heat exchangers, more particularly to a kind of return-air heat exchanger.
Background technology
It is usually mounted with return-air heat exchanger at present, return-air heat exchanger is mainly used in reclaiming in condenser in the equipment such as refrigerator
Cold-producing medium liberated heat, is transported in compressor, for energy regenerating, as depicted in figs. 1 and 2, in the equipment such as current refrigerator
The return-air heat exchanger using is muffler 1 and capillary 2 line and linear contact lay, and capillary 2 is very little with muffler 1 heat exchange area,
So heat exchange efficiency is low, in order to obtain equal heat exchange amount, required heat exchange segment length, high cost and be unfavorable for energy-conservation.
Utility model content
(1) technical problem to be solved
The technical problems to be solved in the utility model is how to increase the heat exchange area of return-air heat exchanger, improve heat exchange effect
Rate, the length reducing heat exchanging segment and reduction energy resource consumption.
(2) technical scheme
In order to solve above-mentioned technical problem, the utility model provides a kind of return-air heat exchanger, including muffler and capillary,
Described muffler and capillary are equipped with plane, and the plane of described muffler is fitted with the plane of described capillary.
Wherein, described muffler and capillary are flat tube.
Wherein, described muffler can be made up of copper pipe, aluminum pipe or steel pipe；Described capillary can by copper pipe, aluminum pipe or
Steel pipe is made.
Wherein, described muffler and described capillary are fitted together by welding, bonding, nested or pyrocondensation.
Wherein, described muffler and described capillary pass through extrusion molding or die casting and molding respectively.
(3) beneficial effect
Compared with prior art, the utility model has the advantage that
A kind of return-air heat exchanger that the utility model provides, including muffler and capillary, muffler and capillary are all provided with
There is plane, the plane of described muffler is fitted with the plane of described capillary, become by the line and linear contact lay of prior art
Face is contacted with face；Increase the contact area of muffler and capillary, improve the coefficient of heat transfer inside pipe, thus improve return-air
The heat exchange efficiency of heat exchanger, in the case of obtaining equal heat exchange amount, required muffler is reduced with the length of capillary, thus subtracting
Little volume shared by return-air heat exchanger, is conducive to energy-saving.
Brief description
Fig. 1 is the schematic perspective view of prior art return-air heat exchanger；
Fig. 2 is the cross-sectional view of Fig. 1；
Fig. 3 is a kind of schematic perspective view of return-air heat exchanger of the utility model；
Fig. 4 is the cross-sectional view of Fig. 3.
In figure: 1: muffler；2: capillary.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Example is used for the utility model is described, but is not limited to scope of the present utility model.
In description of the present utility model, it should be noted that term " " center ", " longitudinal ", " horizontal ", " on ", D score,
The orientation of instruction such as "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom " " interior ", " outward " or position relationship are
Based on orientation shown in the drawings or position relationship, it is for only for ease of description the utility model and simplifies description, rather than instruction
Or the hint device of indication or element must have specific orientation, with specific azimuth configuration and operation, be not therefore understood that
It is to restriction of the present utility model.
In description of the present utility model, it should be noted that unless otherwise clearly defined and limited, term " peace
Dress ", " being connected ", " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected, or integratedly
Connect；Can be to be mechanically connected or electrically connect；Can be to be joined directly together it is also possible to be indirectly connected to by intermediary,
It can be the connection of two element internals.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
Concrete meaning in the utility model for the language.
As shown in Figure 3 and Figure 4, a kind of return-air heat exchanger providing for the utility model, including muffler 1 and capillary 2,
Described muffler 1 and capillary 2 are equipped with plane, and the plane of described muffler 1 is fitted with the plane of described capillary 2.By
The muffler 1 of prior art is become face with capillary 2 line with linear contact lay and is contacted with face；Increase connecing of muffler 1 and capillary 2
Contacting surface is amassed, and improves the coefficient of heat transfer inside pipe, thus improve the heat exchange efficiency of return-air heat exchanger, is obtaining equal heat exchange amount
In the case of, the length of required muffler 1 and capillary 2 is the length reduction of heat exchanging segment, thus reducing shared by return-air heat exchanger
Volume, is conducive to energy-saving.
As Fig. 3 and 4, described muffler 1 and capillary 2 are disposed as flat tube；Refrigerant boundary layer quilt inside flat tube
Destroy, cold-producing medium produces turbulent flow in flat tube, heat exchange strengthens, and improves heat exchange coefficient.Do not affecting cold-producing medium circulation
In the case of, muffler 1 and capillary 2 extruding more flat, heat exchange contact area is bigger, and heat transfer effect is better.
Described muffler 1 and described capillary 2 can pass through extrusion molding or die casting and molding respectively.Wherein, described time
Tracheae 1 can be made up of the good material of the thermal conductivity such as copper pipe, aluminum pipe or steel pipe；Can be directly formed to flat in tubular object extruding
Pipe, or be first shaped to pipe and extrude as flat tube again, described capillary 2 can be good by thermal conductivity such as copper pipe, aluminum pipe or steel pipes
Material is made, and can be directly formed to flat tube in tubular object extruding, or is first shaped to pipe and extrudes as flat tube again.
Wherein, described muffler 1 and described capillary 2 can be assembled in one by modes such as welding, bonding, nested or pyrocondensations
Rise it is ensured that both are reliably connected together.
Preferably, the heat exchanging segment of described muffler 1 and capillary 2 is straight tube, convenient connection.
As can be seen from the above embodiments, muffler 1 of the present utility model is big with capillary 2 contact area, heat transfer efficiency
High；In the case of obtaining equal heat exchange amount, the length of required muffler 1 and capillary 2 is the length reduction of heat exchanging segment, thus
Reduce volume shared by return-air heat exchanger, be conducive to energy-saving.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement made etc., should be included in the utility model
Protection domain within.
