Improved than the heat exchanger efficiency such as traditional pipe type, corrugated tube type, parallel flow type, plate-fin, stacked, but due to there is wing
Piece, easy dust stratification is difficult defrost, and easy ponding, volume is big, and quality is big, and the refrigerant of use or the quantity of refrigerant are also big, and
The pipe surface that exchanges heat is smooth, and surface area-to-volume ratio is low.
Utility model content
The purpose of this utility model is to provide a kind of high heat transfer coefficient, high surface to solve the deficiency of above-mentioned technology
Product-volume ratio, containing multilayer integration slice, size be small, the uniform sufficiently miniature microchannel pipe heat exchanger of heat exchange.
In order to achieve the above object, a kind of miniature microchannel pipe heat exchanger designed by the utility model, including import
Pipe, outlet and heat exchange mechanisms, the heat exchange mechanisms are formed using many miniature microchannel metal circular tubes with support combined crosswise,
The two ends of the heat exchange mechanisms are connected with inlet tube and outlet, the distance between miniature microchannel metal circular tube of direct neighbor
Between 0.7 millimeter to 3 millimeters.The characteristics of this structure, is to eliminate metal fin, and heat exchange mechanisms are used only miniature micro- logical
Road metal external thread pipe integration slice is as main heat exchanger components, in integration slice, miniature microchannel metal external thread pipe and branch
Frame, which intersects to combine, to be coordinated, and miniature microchannel metal external thread pipe both sides entirely exchange heat with the composition that enters to be connected respectively again
Optimal heat exchange distance is employed between device, and miniature microchannel, resistance is small, easily stired and make muddy the refrigerant for entering heat exchanger, greatly
Improve heat exchange efficiency greatly.
Further, described miniature microchannel metal circular tube be miniature microchannel metal internal thread round copper pipe, it is miniature
Microchannel metal external thread round copper pipe, or miniature microchannel metal internal and external threads round copper pipe.
Further, described timbering material is plastics.
Further, described support can be metallic support or non-metal frame, as being preferred to use metallic support, and
Metallic support is welded to connect with miniature microchannel metal circular tube.
In order to further increase heat exchange efficiency, be easy to welding operation, groove is set on metallic support.
In order to adapt to various use environments, described inlet tube and outlet using different-diameter metal circular tube, flat
Pipe or type pipe, fluting or perforate on its tube wall, miniature microchannel metal external thread pipe by described fluting or perforate with
Inlet tube, outlet are welded and fixed.
Further, set in described inlet tube and outlet by slotting to be provided with division board, described division board
There is conduction hole.
In order to strengthen the service life of heat exchanger, the heat exchange mechanisms surface, and the surface of inlet tube and outlet are equal
Provided with corrosion proof and leakproof layer.
It is noted that described miniature microchannel pipe heat exchanger, is referred to as the miniature microchannel metal of non-finned
Pipe heat exchanger.In air-cooled application field, it is referred to as miniature microchannel Wind-cooling type light pipe heat exchanger or non-finned is miniature
Microchannel Wind-cooling type metal circular tube heat exchanger.
Miniature microchannel pipe heat exchanger designed by the utility model, by setting between miniature microchannel metal circular tube
Optimal distance and miniature microchannel metal circular tube between optimal setting so that enter heat exchanger refrigerant obtain sufficient heat
Exchange, and the design of non-finned causes refrigerant more easily by heat exchanger.Air-conditioning of the present utility model improves heat transfer effect, also
Lightweight with small volume, refrigerant usage amount is few, energy-conserving and environment-protective, is difficult ponding, is difficult dust stratification and reduction packaging, transport
And the features such as installation cost.
