Abstract
A micro-channel heat exchanger with optimized drainage belongs to the technical field of heat exchangers and comprises a left collecting pipe, a right collecting pipe, a plurality of flat pipes and fins, wherein the flat pipes are horizontally arranged, and the two ends of the flat pipes are respectively communicated with the left collecting pipe and the right collecting pipe; fins are arranged between every two adjacent flat pipes, and protrude from the planes of the flat pipes in the directions of windward side and/or leeward side, on that account, water accumulating at the roots of the fins smoothly flows out of the heat exchanger along the edges of the fins, accumulated condensed water is reduced, and drainage capacity of the heat exchanger is improved. The micro-channel heat exchanger has the advantages of effective enhancement of drainage effect, improvement on heat exchange efficiency and enlargement of application range.
Description
Technical field
What the present invention relates to is a kind of device of heat exchanger technical field, specifically is a kind of micro-channel heat exchanger of optimizing draining that has.
Background technology
Micro-channel heat exchanger is compared with the conventional tube plate heat interchanger, has compact conformation, weight saving, and cost is lower, and heat exchange efficiency is advantages of higher more.When micro-channel heat exchanger in heat pump during as evaporimeter, its surface can produce condensed water.The cramped construction of micro-channel heat exchanger can cause condensed water to gather the fin root and form the water bridge between fin, hinders air and flows and heat exchange, and heat exchanger performance is descended.In order to improve the drainage performance of micro-channel heat exchanger, header is horizontally disposed with, flat tube is vertically mounted between the header.But the difficulty that actual installation is brought has limited the range of application of this method.
Find through the retrieval to prior art, Chinese patent literature CN201449172, open day 2010-05-05, put down in writing a kind of micro-channel heat exchanger with drain function, comprise collector, micro-channel flat and fin, micro-channel flat is connected on the collector and with collector and communicates, and walking abreast in micro-channel flat is provided with a plurality of fins, be provided with osculum at each fin, the osculum on each fin runs through mutually.But the prior art practical operation inconvenience, and the defective of comparing with the present invention and deficiency are that its fin processing technology is more complicated, are not easy to realize, and require heat exchanger vertically to install, the certain angle that perhaps tilts, the scope of having dwindled the actual use of micro-channel heat exchanger.
Summary of the invention
The present invention is directed to the prior art above shortcomings, a kind of micro-channel heat exchanger of optimizing draining that has is provided, can solve the drainage problem of micro-channel heat exchanger when flat tube is horizontally disposed with.
The present invention is achieved by the following technical solutions, the present invention includes: left header, right header, some flat tubes and fin, wherein: flat tube is horizontally disposed with, its two ends are connected with left header and right header respectively, be provided with fin between the adjacent flat tube, fin protrudes from the setting of flat tube plane in windward side and/or leeward side direction, makes the water that accumulates in the fin root along the smooth outflow heat exchanger in edge that protrudes fin, reduce the condensed water that gathers, improve drainability.
The length of the protrusion of described fin is smaller or equal to 5mm, and in this scope, along with the length of protruding increases, the heat exchanger drainage performance can improve, and behind 5mm, drainage performance improves not obvious.
The coupling part of the fin of the protrusion of described windward side direction is cut.
The coupling part of the fin of the protrusion of described leeward side direction is cut.
Because the induced effect of wind, most of condensed water can flow to the leeward side direction, cut the coupling part of the fin leeward side of described protrusion, the coupling part of the protrusion fin of windward side direction remains unchanged, increase the drainability of leeward side, can improve the heat exchanger overall performance, can save the production time simultaneously, reduce cost.
Described leeward side direction is or/and the coupling part of the fin of the protrusion of windward side direction is cut off, and the fin that protrudes launches towards the vertical direction one or both sides of flat tube.
Described fin be shaped as waveform or shutter shape or flat form or its combining form.
The present invention can effectively improve the drainage effect of micro-channel heat exchanger, improves the heat exchange efficiency of heat exchanger, has increased the scope of application of micro-channel heat exchanger.According to actual conditions, select the setting of fin form and protrusion, when satisfying the drainability requirement, improve the exchange capability of heat of heat exchanger.

The specific embodiment
Below embodiments of the invention are elaborated, present embodiment is being to implement under the prerequisite with the technical solution of the present invention, provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1, embodiment comprises: left header 1, right header 2, some flat tubes 3 and fin 4; Flat tube 3 is horizontally set between left header 1 and the right header 2, and communicates with both; Between adjacent flat tube 3, be provided with fin 4.[0026] as shown in Figure 2, fin 4 protrudes from the setting of flat tube 3 planes in windward side and/or leeward side direction, makes the water that accumulates in fin 4 roots along the smooth outflow heat exchanger in edge that protrudes fin 4, reduces the condensed water that gathers, and improves drainability.
The length of fin 4 projections is between 0～5mm.
Fin 4 main body shapes are waveform.
As shown in Figure 3: along with fin 4 projection length l rise to 5mm, the decline rapidly of the residual water yield of micro-channel heat exchanger gradually from 0.But when continuation increased after fin 4 protrudes length to surpass 5mm, the residual water yield of micro-channel heat exchanger can remain on very low level and continue and descend to some extent, but decline scope is also not obvious.
Embodiment 2
As Fig. 4, shown in Figure 5, in windward side and leeward side direction, fin 44 protrude planes, flat tube 3 place, outstanding length is lmm, and the coupling part of the fin 4 that protrudes is cut.Further increase the drainability of fin 4.
Fin 4 main body shapes are the shutter form.
Fin 4 main body shapes are flat form.
Fin 4 main bodys are the mixed form of corrugated plate, shutter or plain fin.
As shown in Figure 6 and Figure 7, cut the coupling part of fin 4 leeward sides of protrusion, the coupling part of the protrusion fin 4 of windward side direction remains unchanged, because the induced effect of wind, most of condensed water can flow to the leeward side direction, increases the drainability of leeward side, can improve the heat exchanger overall performance, can save the production time simultaneously, reduce cost.
As Fig. 8, shown in Figure 9, the coupling part of the fin 4 of the protrusion of described leeward side direction and windward side direction is cut off, and the fin 4 that protrudes launches towards the vertical direction both sides of flat tube 3.
Embodiment 5
As shown in figure 10, the fin 4 of protrusion only is set in the leeward side direction, and the fin 4 that protrudes launches towards the vertical direction both sides of flat tube 3.
Embodiment 6
As shown in figure 11, the coupling part of the fin 4 of the protrusion of described leeward side direction and windward side direction is cut off, and the fin 4 that protrudes launches towards vertical direction one side of flat tube 3.
