The method that refrigeration industry improves the unit efficiency is a lot, and wherein forming suitable degree of supercooling is a kind of satisfactory method.Degree of supercooling is the saturated liquid temperature of condenser condenses pressure correspondence and the difference of condensator outlet liquid actual temperature.During the refrigeration system normal circulation, the outlet of condenser generally all can have certain degree of supercooling.If there is not degree of supercooling, the pressure in " liquid pipe " of the liquid in the two-phase refrigerant has loss slightly, and liquid will shwoot, saturated liquid since the reduction of pressure will inevitably evaporate.Heat around the liquid evaporation can absorb, remaining liquid is lowered the temperature thereupon, reaches the saturation temperature under the relevant pressure again, and advance in two-phase refrigerant limit like this, the limit shwoot, the limit is saturated, up to arriving evaporator inlet.The final mass dryness fraction that arrives the two-phase refrigerant of evaporimeter will be more a lot of greatly than the mass dryness fraction of design, and liquid phase ingredient reduces, and just can't satisfy the evaporation capacity of evaporimeter, and refrigeration does not reach requirement.If the two-phase refrigerant enters throttling arrangement (as expansion valve) oscillatory occurences can take place in addition.Because vibration then may produce noise.Based on above these reasons, in exploitation during refrigeration system, generally all can require condenser after, before the throttling arrangement, certain degree of supercooling (being 3 ℃~5 ℃ generally speaking) is arranged, degree of supercooling is too big or too little all unfavorable to system.Forming suitable degree of supercooling has several different methods, and wherein the cooling effect again of built-in subcooler is better in condenser, and cost is lower and system architecture is simple, and cost performance is higher, therefore uses comparatively extensive.
There is following problem at least in the built-in subcooler structure of existing condenser: parts are more, and the welded and installed more complicated needs the workman to carry out too much weld job in condenser shell, and labour intensity is big, and the heat exchange poor effect.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of shell-and-tube cooler is provided.
Purpose of the present invention is achieved through the following technical solutions:
The shell-and-tube cooler that has built-in subcooler, comprise condenser shell and left tube sheet that is connected with condenser shell and right tube sheet, form enclosed construction, condenser shell is provided with the refrigerant vapour inlet connection that communicates with the condenser shell inner chamber, last heat exchanger tube and following heat exchanger tube all run through the inner chamber of condenser shell, its two end supports is on left tube sheet and right tube sheet, characteristics are: the bottom of described condenser shell inner chamber is provided with subcooler, described subcooler comprises the frid of slot type structure, be arranged at the cover plate on the frid and be arranged at a frid left side, in, the gripper shoe at right three places, following heat exchanger tube penetrates the inner chamber of cooler, the two ends of described frid have the inlet that enters for refrigerant liquid, the bottom of described frid is provided with the feeder that compiles for refrigerant liquid, and described feeder is taken over the refrigerant outlet that is arranged at the condenser shell bottom and is connected.
Further, the above-mentioned shell-and-tube cooler that has built-in subcooler, wherein, the cover plate of described subcooler is provided with the flanging structure that is connected with frid.
The substantive distinguishing features of technical solution of the present invention and progressive being mainly reflected in:
Subcooler is installed in the condenser shell after installing outside condenser shell earlier again, has reduced the weld job amount of workman in condenser shell, has reduced labour intensity, can shorten the production cycle of condenser, reduces production costs.After this device is implemented in condenser, before the throttling arrangement, form suitable degree of supercooling.And subcooler and condenser shell inwall have certain interval, and cold-producing medium enters subcooler from the bottom of subcooler, and the heat exchange effect is better.
