Abstract
The invention discloses a microchannel heat exchanger. The microchannel heat exchanger is an evaporator of a refrigerating system, wherein the refrigerating system further comprises a compressor, a condenser and a throttling device; the microchannel heat exchanger is an all-aluminum heat exchanger and comprises an upper head pipe, a lower head pipe and flat pipes; the flat pipes are positioned between the upper head pipe and the lower head pipe and are arranged in parallel; a refrigerant enters the microchannel heat exchanger from the lower head pipe, is subjected to heat exchange by the flat pipes and flows out from the upper head pipe; the lower head pipe comprises a first distribution chamber and a third distribution chamber; and the upper head pipe comprises a second distribution chamber and a fourth distribution chamber. According to the microchannel heat exchanger disclosed by the invention, due to the utilization of the separated distribution chambers, the refrigerant entering the microchannel evaporation heat exchanger is uniformly distributed and the heat exchange efficiency is greatly increased.
Description
Technical field
The present invention relates to a kind of refrigeration plant, or rather, is a kind of novel little for refrigeration system
The passage evaporimeter, namely
Micro-channel heat exchanger.
Background technology
In general refrigeration system, comprise compressor, condenser, throttling arrangement and evaporimeter.
The coil pipe that traditional evaporimeter generally adopts copper pipe to curve, this evaporimeter is very big to the demand of copper material, and cost is very high, and cost recovery is high.And the full aluminium heater in microchannel more and more comes into one's own as a kind of novel heat exchanger.In addition, compare with the finned tube exchanger that another kind is traditional, it is about about 20% that the performance of micro-channel heat exchanger on average can improve, and the charging amount of unit cold-producing medium on average can reduce about 20%.Heat exchanger is all made through soldering by a kind of materials of aluminum, has avoided potential corrosion, is easy to reclaim, and therefore can guarantee the more long-term efficient use of heat exchanger.As the microchannel evaporating heat exchanger, its distributing uniformity to two phase refrigerant is the emphasis of research.
Summary of the invention
The present invention mainly is the technical problem that solves the existing insufficiency of function of prior art, thereby a kind of micro-channel heat exchanger of simple in structure, cold-producing medium distributed uniform is provided.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of micro-channel heat exchanger, described micro-channel heat exchanger is the evaporimeter of a refrigeration system, described refrigeration system also comprises compressor, condenser, throttling arrangement, and described micro-channel heat exchanger is full aluminium heater.
As preferably, described micro-channel heat exchanger comprise head tube, lower head tube and on described the flat tube that is arranged in parallel between head tube and the lower head tube, cold-producing medium enters into micro-channel heat exchanger from described lower head tube, flows out from upper head tube after the flat tube heat exchange.
As preferably, described lower head tube comprises the first dispensed chambers and the 3rd dispensed chambers, described upper head tube comprises the second dispensed chambers and the 4th dispensed chambers, after described cold-producing medium enters into micro-channel heat exchanger from the entrance of lower head tube, enter into successively described the first dispensed chambers, the second dispensed chambers, the 3rd dispensed chambers and the 4th dispensed chambers, flow out from the outlet of described upper head tube at last.
As preferably, comprise division board between described the first dispensed chambers and the 3rd dispensed chambers, the second dispensed chambers and the 4th dispensed chambers comprise division board on.
Therefore, by technique scheme, micro-channel heat exchanger of the present invention utilizes the distribution cavity of each separation, obtains uniform distribution so that enter into the cold-producing medium of microchannel evaporating heat exchanger, has greatly improved heat exchange efficiency.

The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention are made more explicit defining.
The invention provides a kind of micro-channel heat exchanger of simple in structure, cold-producing medium distributed uniform.
As depicted in figs. 1 and 2, a refrigeration system comprises compressor 1, condenser 4, throttling arrangement 3 and evaporimeter 2, and this micro-channel heat exchanger 2 is full aluminium heater.
This micro-channel heat exchanger 2 comprise head tube 21, lower head tube 22 and on this flat tube that is arranged in parallel 23 between head tube 21 and the lower head tube 22, cold-producing medium enters into micro-channel heat exchanger from this time head tube 22, flows out from upper head tube 21 after flat tube 23 heat exchange.
This time head tube 22 comprises the first dispensed chambers 228 and the 3rd dispensed chambers 229, should comprise the second dispensed chambers 218 and the 4th dispensed chambers 219 by upper head tube 21c, after this cold-producing medium enters into micro-channel heat exchanger from the entrance 221 of lower head tube 22, enter into successively this first dispensed chambers 228, the second dispensed chambers 218, the 3rd dispensed chambers 229 and the 4th dispensed chambers 219, the outlet 211 of head tube is flowed out on this at last.
Comprising between this first dispensed chambers 228 and the 3rd dispensed chambers 229, division board 223, the second dispensed chambers 218 and the 4th dispensed chambers 219 comprise division board 213 on.
Owing to adopted four different dispensed chambers, cold-producing medium obtains four distribution in the process of advancing, and the distributing uniformity of cold-producing medium is greatly enhanced, and therefore, the heat exchange efficiency of whole evaporimeter is improved.
Below only with an embodiment mentality of designing of the present invention is described, in the situation that system allows, the present invention can expand to simultaneously external more functional module, thereby expands to greatest extent its function.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.
