Abstract
The utility model discloses a screw dry type evaporator comprising a front end air chamber (1). A liquid inlet pipe (2) which is communicated with the front end air chamber (1) is arranged on the outer wall of the lower part of the front end air chamber (1); a liquid collecting chamber (3) which is communicated with the liquid inlet pipe (2) is arranged at an outlet on the inner wall of the front end air chamber (1), which corresponds to the liquid inlet pipe (2); and the liquid collecting chamber (3) is provided with at least two liquid distributing pipes (4) which are communicated with the liquid collecting chamber (3). The screw dry type evaporator disclosed by the utility model has the advantages of ingenious structure design and simplicity in manufacturing and installation; with the adoption of the screw dry type evaporator, refrigerant fluid can be uniformly distributed when entering a heat exchange pipe, so that the refrigerating effect is improved.
Description
Technical field
The utility model relates to a kind of evaporimeter, particularly a kind of screw rod dry evaporator.
Background technology
Existing all kinds of screw rod water-cooled dry evaporator refrigeration unit is work like this: the low-temp low-pressure liquid refrigerant after the expansion valve throttling, a feed tube that links to each other with expansion valve through front end air chamber lower middle position directly gets into the heat exchanger tube that front end air chamber bottom is surrounded.This mode can't guarantee every heat exchanger tube feed liquor amount that front end air chamber bottom is surrounded evenly, thereby can't make full use of the heat exchange area of every pipeline, cause refrigerating efficiency to descend.
The utility model content
The purpose of the utility model just provides a kind of screw rod dry evaporator that improves refrigeration.
The purpose of the utility model is to realize through such technical scheme; A kind of screw rod dry evaporator; Comprise the front end air chamber; The outer wall of front end air chamber bottom is provided with the feed tube that communicates with the front end air chamber, and corresponding feed tube outlet is provided with the liquid collecting cavity that communicates with feed tube on front end air chamber inwall, and liquid collecting cavity is provided with at least two separating tubes that communicate with liquid collecting cavity.
Wherein, above-mentioned separating tube is separately positioned on the upper, middle and lower of liquid collecting cavity, saidly is provided with 1～5 separating tube on top, is provided with 1～4 separating tube at the middle part, is provided with 1～3 separating tube in the bottom.
Owing to adopted technique scheme, the utlity model has structural design ingenious, make simple advantage be installed, adopt it to make cold-producing medium obtain distributing more equably when getting into heat exchanger tube, improved refrigeration.
Description of drawings
The description of drawings of the utility model is following:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the cutaway view of A-A among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation; But the utility model is not limited to these embodiments; Any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1; A kind of screw rod dry evaporator; Comprise front end air chamber 1; The outer wall of front end air chamber 1 bottom is provided with the feed tube 2 that communicates with front end air chamber 1, and corresponding feed tube 2 outlets are provided with the liquid collecting cavity 3 that communicates with feed tube 2 on front end air chamber 1 inwall, and liquid collecting cavity 3 is provided with at least two separating tubes 4 that communicate with liquid collecting cavity 3.
Further, as shown in Figure 2, said separating tube 4 is separately positioned on the upper, middle and lower of liquid collecting cavity 3, and said top at liquid collecting cavity 3 is provided with 3 separating tubes 4, is provided with 2 separating tubes 4 at the middle part, is provided with 1 separating tube 4 in the bottom.
During unit operation; Liquid refrigerant after the throttling gets in the liquid collecting cavity 3 through feed tube; Rely on the separating tube 4 be arranged on the liquid collecting cavity 3 that cold-producing medium is sprayed into the zone of separating tube institute radiation again and since separating tube 4 in the space area occupied more much bigger than single feed tube, so radiation areas are also much bigger; Reach the purpose of uniform distribution liquid refrigerant thus, improved the unit refrigerating efficiency.
In the utility model,,, reduce heat transfer efficiency and heat transfer area so it is on the low side or the feed liquor dead band occurs to have avoided being in the heat exchanger tube feed liquor amount at position, front end air chamber 1 corner because cold-producing medium obtained uniform distribution when entering into heat exchanger tube 5; Also avoided the feed liquor of liquid refrigerant to concentrate on the heat exchanger tube zone of single feed tube institute radiation simultaneously, caused this zone feed liquor amount greater than design load in advance, the pressure reduction at evaporimeter import and export place increases because of the increase of flow resistance, reduces coefficient of refrigerating performance.
In the utility model, the radical of separating tube 4 can be provided with according to varying in size of front end air chamber 1 voluntarily, wherein, because it is more to be in the heat exchanger tube 5 on air chamber top, so it is also more to be arranged on the separating tube 4 on liquid collecting cavity 3 tops; The heat exchanger tube 5 that is in the air chamber bottom is less, so it is also less to be arranged on the separating tube 4 of liquid collecting cavity 3 bottoms; Simultaneously, the utility model is equally applicable to the version that the front end air chamber has a plurality of independent partitions, and promptly each independent partitions all has liquid collecting cavity and the separating tube radical that is complementary with this district's size, reaches the purpose of this district's liquid refrigerant uniform distribution.
