Description
Technical field
The utility model relates to refrigeration air-conditioner field, particularly relates to a kind of passage evaporative condenser.
Background technology
Evaporative condenser is the main heat transmission equipment in refrigeration system, its operation principle is: the heat exchanger tube of overheated higher pressure refrigerant gas in evaporative condenser that in refrigeration system, compressor is discharged, spray water and air outside the cold-producing medium of high-temperature gas and pipe carries out heat exchange, the super-strong wind-power of supporting air-introduced machine makes shower water cover the surface of heat exchanger tube, shower water part evaporation after heat absorption, utilize the latent heat of vaporization of water to take away a large amount of heats by wind, and cold-producing medium is condensed into liquid state gradually by gaseous state after releasing heat.The utility model patent being 201020547287.7 as application number discloses a kind of condenser, it forms by a metal tube is bending, comprise the first body of many approximate horizontal layouts and connect the second body of adjacent two the first bodys, each second body at least partially body is straight length, the center line of this straight length is located on a straight line, described straight length is positioned at the middle part of the second body, the two ends of described second body are also respectively equipped with the transitional pipe segment of transition connection straight length and the first adjacent body, described transitional pipe segment is curved, although this condenser reaches certain radiating effect, but due to the finite surface area of heat exchanger tube, and be limited to the volume of equipment, larger heat exchange area demand cannot be met, under the impact of strong fan, cooling water heat exchanger tube surface or around unorderedly to wave, heat exchanger tube surface cannot be covered completely, not only reduce heat exchange efficiency, and easily formation fouling is done in existence, heat exchanger tube is caused easily to occur the risk be corroded.For the problem that heat exchanger tube heat exchange area is little, exchange heat pipe in field and install fin additional to increase heat exchange area, the utility model patent being 201320145135.8 as application number discloses a kind of Novel condenser fin, in the program, fin is that the coiling of uniform spiral is in condenser outer walls, make the surrounding heat radiation of condenser pipe outer ring evenly, the edge of fin and condenser pipe wall contacts is wave-like, increases the contact surface of condenser pipe and fin.The program is applied in condenser, although reach the effect of certain increase heat exchange area, still cannot solves the cooling water problem of waving, heat exchanger tube cannot be covered completely unordered under the impact of strong fan.
After traditional heat exchanger tube rearranges condenser, distinguished and admirablely vertically blow over heat exchanger tube, the distinguished and admirable resistance be subject to is sizable, distinguished and admirablely significantly reduces through wind speed after heat exchanger tube, causes heat exchange uneven.Because heat exchanger tube great majority are pipe, distinguished and admirable when blowing over heat exchanger tube with cooling water, easily form eddy current at the leeward side of heat exchanger tube, cause heat exchanger tube windward side and leeward side to be heated more uneven, affect overall heat exchange efficiency and increase power consumption.
Utility model content
In view of this, the purpose of this utility model is to overcome the deficiencies in the prior art, a kind of passage evaporative condenser is provided, solve existing evaporative condenser due to heat exchanger tube surface area limited and the demand of larger heat exchange area, cooling water coverage rate is low, flowing resistance is large problem cannot be met.
In order to solve the problems of the technologies described above, the utility model adopts following scheme to realize:
A kind of passage evaporative condenser, comprise multiple fin heat exchange pipe, discharge and collector tube, described fin heat exchange pipe is arranged side by side, and its entrance is communicated with discharge, outlet is communicated with collector tube, described fin heat exchange pipe comprises the heat exchanger tube curving one or more continuous U-shaped, connects fin between the straight length of described heat exchanger tube, makes heat exchanger tube form continuous print plane.
High temperature liquid refrigerant enters discharge, then shunt and enter heat exchanger tube from the import of each heat exchanger tube, after carrying out heat exchange with the cooling water and air outside heat exchanger tube, cold-producing medium is released heat and is condensed into liquid state and is collected to collector tube from the outlet of heat exchanger tube, and is discharged by collector tube.The heat exchange area that fin can increase heat exchanger tube is set between the straight length of heat exchanger tube, and the continuous level energy guide cooling water formed flows to bottom heat exchanger tube from heat exchange of top part pipe, decrease the unordered of cooling water to wave, improve the cooling water coverage rate on heat exchanger tube surface, improve heat exchange efficiency.Distinguished and admirablely to pass along the direction parallel with straight length with cooling water, decrease distinguished and admirable resistance, also there is not heat exchanger tube windward side and leeward side and to be heated uneven phenomenon.
The straight length both sides of described heat exchanger tube are also connected with fin, and are provided with multiple through hole in junction.Certain metric space is also there is between the fin heat exchange pipe be arranged side by side, and well do not used by the cooling water in this space, therefore also fin is connected with in the both sides of the straight length of heat exchanger tube, make the heat exchange area adding heat exchanger tube in the horizontal, greatly improve the utilization rate of cooling water, further improve the overall heat exchange efficiency of condenser.
The fin of the straight length both sides of described heat exchanger tube is the arcuate structure fin be bent upwards.Heat in heat exchanger tube upwards transmits from junction, and cooling water flows downward from the fin top of arcuate structure, and countercurrent flow effect is better.
Preferably, the fin between the straight length being arranged on heat exchanger tube is plain fin, corrugated fin or perforated fin.
Preferably, described heat exchanger tube is pipe, elliptical tube, bellows tube or helix tube.
Preferably, be welded and fixed between described fin and heat exchanger tube.
Compared with prior art, the utility model has following beneficial effect:
(1) the utility model is by arranging fin at the straight length of U-shaped heat exchanger tube, make between heat exchanger tube, to form continuous print plane, guide cooling water flows to lower floor's heat exchanger tube from upper strata heat exchanger tube, reduce the unordered of cooling water to wave, improve the cooling water coverage rate on heat exchanger tube surface, thus improve heat exchange efficiency and reduce fouling, corrosion risk;
(2) except connecting except fin between the straight length of heat exchanger tube, also fin is set in the straight length both sides of heat exchanger tube, has both increased the longitudinal heat exchange area of heat exchanger tube, also increased its horizontal heat exchange area, improve the utilization rate of cooling water, further increasing heat exchange efficiency;
(3) the utility model flexible design, simple and reliable for structure, meets heat exchange instructions for use.
