The utility model discloses a full-countercurrent heat exchanger in the technical field of heat exchangers, and aims to solve the problems that in the prior art, a U-type pipe heat exchanger cannot achieve full-countercurrent heat exchange, and is poor in heat exchange efficiency and uniform in heat exchange medium distribution. The heat exchanger comprises a shell body, wherein a plurality of evaporation pipes are arranged in the shell body, two ends of each evaporation pipe are respectively provided with a pipe plate, two ends of the shell body are respectively provided with an end cap, the end caps at the two ends of the shell body are provided with a refrigerant inlet and a refrigerant outlet respectively, one end of the shell body is provided with a secondary refrigerant outlet corresponding to the refrigerant inlet, the other end of the shell body is provided with a secondary refrigerant inlet corresponding to the refrigerant outlet, a distribution plate is arranged in the end cap corresponding to the refrigerant inlet and is provided with a plurality of through holes in the radial direction, the insides of the through holes are connected with distribution pipes in the one-to-one correspondence and expansion mode, the distribution pipes and the evaporation pipes are in one-to-one correspondence, and the distribution pipes extend to be inserted into the evaporation pipes. The heat exchanger can achieve full-countercurrent heat exchange, heat exchange effects are strengthened, and compared with the traditional U-type pipe heat exchanger, the heat exchange improves heat exchange capacity by over 10%.
Description
Technical field
The utility model relates to a kind of heat exchanger, particularly a kind of full contra-flow heat exchanger.
Background technology
Of the prior art have a kind of U-shaped heat exchange of heat pipe, an end that comprises housing is provided with tube sheet, the outside of tube sheet is provided with end cap, the other end of housing then is provided with channel closure, tube sheet is provided with the U-shaped tube bank of at least two groups, each U-shaped tube bank is positioned at the housing of heat exchanger, and the import of each U-shaped pipe, outlet are separated by the dividing plate that is fixed in the end cap, also are provided with feed tube and drain pipe on the housing.During work, refrigerating medium enters in the housing from the feed tube of housing, and cold-producing medium enters in the U-shaped pipe from the import of U-shaped pipe, and cold-producing medium evaporation heat absorption makes refrigerant temperature reduce, and realizes circularly cooling.
Its weak point is, the shell side of the U-shaped heat exchange of heat pipe of said structure is one way, be difficult to form real countercurrent flow, along with heat transferring medium flowing in tube side, and carry out heat exchange, its medium temperature can raise gradually, and the medium of the medium of shell side and tube side elder generation and the heat exchange of high temperature tube side medium can occur when carrying out heat exchange, the back with the heat exchange of low temperature tube side medium, with the heat exchange of high temperature tube side medium; Perhaps, be limited to the heat exchange of low temperature tube side medium, afterwards with the heat exchange of high temperature tube side medium, ask the situation of heat exchange again with the leap of low temperature tube side medium heat exchange, reduced the heat exchange effect.
The utility model content
The purpose of this utility model is at deficiency of the prior art, and a kind of full contra-flow heat exchanger is provided, and has the advantage that separatory is even, heat exchange efficiency is high.
The purpose of this utility model is achieved in that a kind of full contra-flow heat exchanger, comprise housing, be provided with some evaporation tubes in the described housing, the two ends of evaporation tube are respectively equipped with tube sheet, the two ends of described housing are respectively equipped with end cap, be respectively equipped with refrigerant inlet and refrigerant outlet on the end cap at housing two ends, the refrigerating medium that offers that one end of described housing is corresponding with described refrigerant inlet exports, the other end of housing is corresponding with described refrigerant outlet offers the refrigerating medium import, be provided with distribution plate in the end cap of the corresponding end of described refrigerant inlet, radially offer some through holes on the described distribution plate, in the described through hole one by one corresponding expanded joint distributing pipe is fixedly arranged, distributing pipe and described evaporation tube are corresponding and extend and insert in the described evaporation tube one by one.
During the utility model work, cold-producing medium injects in the end cap cavity by refrigerant inlet, evenly mixes entering in each distributing pipe by high-pressure injection, flows in the evaporation tube, simultaneously, the refrigerating medium of high temperature enters in the evaporator shell through the refrigerating medium import, after cold-producing medium and the refrigerating medium generation heat exchange, and the cold-producing medium heat absorption of fully vaporizing, make refrigerant temperature reduce, the refrigerating medium that temperature is lower pumps from the refrigerating medium outlet, realizes the cold conveying through the outer loop passage, and circulation realizes process of refrigerastion and so forth.Compared with prior art, the beneficial effects of the utility model are: the import department at cold-producing medium arranges the even separatory that distributing pipe is realized cold-producing medium, and cold-producing medium is fully utilized, the heat exchange efficiency height; The corresponding setting with refrigerant outlet of refrigerating medium import, the corresponding setting with refrigerant inlet of refrigerating medium outlet realizes full countercurrent flow, further strengthens the heat exchange effect, compares the exchange capability of heat that can improve greater than 10% with the U-shaped heat exchange of heat pipe of tradition.
For refrigerating medium and refrigerant charging are divided heat exchange takes place, the tube side of described evaporation tube partly is provided with some hydraulic barriers.Hydraulic barrier makes refrigerating medium detour in housing, has prolonged heat-exchange time, has increased the heat exchange effect.
Be provided with sealing joint strip between described distribution plate periphery and the described end cap.Enter in each distributing pipe because cold-producing medium sprays through external high pressure, install the air-tightness that sealing joint strip can fully guarantee heat exchanger additional, to realize good homogeneous separatory effect, improve heat exchange efficiency.
