The structural design of the invention can eliminate dead angle of air flowing, reduce drag force of the air flowing, simultaneously dustproof coating which has the function of dust prevention is arranged, heat exchanging efficiency of the heat-exchange device is guaranteed, and air flowing noise is reduced.
Description
Technical field
The present invention relates to the novel parallel stream heat-exchanger rig in a kind of field of Refrigeration and Air-conditioning.
Background technology
What the heat exchanger in the refrigeration air-conditioner used mostly is finned heat exchanger, the structure of this heat exchanger is that the mode string by mechanical expanding is with many thin type heat exchange fins (mostly being aluminium fin or copper fin) outside the cycle heat exchange pipe, refrigerant flows through in the cycle heat exchange pipe, air then reaches outside copper pipe the gap of heat exchange fin and flows through, to realize the heat exchange of refrigerant and air.Because the existence of these heat exchanger tubes (cross section mostly is pipe), must be subjected to when air flows through the fin gap stopping bigger windage is arranged, and there is the dead angle easily, when under the more environment of dust, using air-conditioning equipment (such as industrial cabinet air conditioner or on-board air conditioner etc.), dust in air can be gathered gradually to stick on the fin and forms grey dust and dirt layer, particularly heat-transfer area during by water-wet the dust dirt can form bigger thermal resistance, the heat exchange effect of heat exchanger obviously descends.The grey dust and dirt layer of fin gap formation influences passing through smoothly of air in addition, and noise also can increase when wind resistance increased.
The layout of present parallel-flow heat exchanger structure all be the flat heat exchange pipe plane perpendicular to the intensive layout of header axis direction, between flat tube with being welded with the tortuous fin that extends.In the use, air-flow be vertically by the two-side current collecting pipe and between the plane that forms of flat tube carry out heat exchange.This heat exchanger structure can have a strong impact on the heat exchange efficiency of heat exchanger and increase pneumatic noise under the situation of air flow spaces very little (for example heat exchanger that uses in the cabinet air conditioner).
Summary of the invention
The object of the invention provides a kind of heat-exchanger rig, and its structural design can be eliminated the air flow blind angle, reduce air flow resistance, is provided with dustproof coating simultaneously, possesses dust reduction capability, has ensured the heat exchange efficiency of heat exchanger, has reduced pneumatic noise.
Technical scheme of the present invention is: a kind of heat-exchanger rig, the cold-producing medium air inlet pipe and the cold-producing medium drain pipe that are provided with on flat heat exchange pipe that comprises baffle plate in the header that is distributed in both sides and is provided with in opposite directions, the header, is communicated with two headers and be arranged in parallel each other and the header, the axis direction of described flat heat exchange pipe width and header be arranged in parallel.
The more detailed technical scheme of the present invention is: a kind of heat-exchanger rig, comprise the cold-producing medium air inlet pipe and the cold-producing medium drain pipe that are provided with on the flat heat exchange pipe that is communicated with between baffle plate in the header that is distributed in both sides and is provided with in opposite directions, the header, two headers and the header, the axis direction of described flat heat exchange pipe width and header be arranged in parallel; Described flat heat exchange pipe is evenly distributed with many rows up and down along the header axis direction, is crisscross arranged between every adjacent two row's flat heat exchange pipe; Described flat heat exchange pipe outer surface is provided with dustproof coating; Described dustproof coating is a Teflon coating.
Advantage of the present invention is:
1. the present invention compares its structure with traditional parallel-flow heat exchanger unit and has carried out thorough improvement, the axis direction of flat heat exchange pipe width and header be arranged in parallel, air is along the axis direction fluid interchange of header, and air drag is little and eliminated the dead angle that air flows.
2. be crisscross arranged between the every adjacent two row's flat heat exchange pipe of the present invention, when air flows through flat heat exchange pipe, can strengthen air agitation, destroy the boundary layer that air flows, improve the heat exchange efficiency of heat exchanger.
3. the flat heat exchange pipe outer surface of new type heat exchanger of the present invention scribbles a dustproof coating, reduces the aggregate amount of dust, and the layout of flat heat exchange pipe also is convenient to clear up dust, has solved the design of heat transfer space compact structure.
