Abstract

The utility model relates to a high efficient evaporator for a refrigerating system. The utility model comprises a stirring cylinder barrel provided with a front connecting plate, a back connecting plate and a feeding pipe, and an outer sleeve, wherein, the periphery of the stirring cylinder barrel is encapsulated with an inner screw helical outer sleeve pipe, and the tooth top of a screw thread of the outer sleeve pipe and the peripheral wall of the stirring cylinder barrel are sealed. The utility model has the advantages of simple structure, easy fabrication, low cost, high productive efficiency and obvious refrigeration effect.

Description

The refrigeration system high-efficiency evaporator

The utility model relates to the evaporimeter that a kind of refrigeration system is used, particularly a kind of internal thread helix tube cylinder evaporimeter.

At present, along with the development of Refrigeration Technique, various refrigeration plants are applied to aspects such as ice cream maker, freezer, air conditioner in succession.In the cylinder refrigerating evaporator of refrigeration system, its structure mainly contains around tubular evaparator, finned evaporator.The former is stirring cylinder barrel periphery winding copper pipe, and cold-producing medium absorbs the heat that cylinder barrel spreads out of by the copper pipe passage.Because of contact-making surface between copper pipe and the cylinder barrel is little, so heat transfer property is relatively poor, refrigerating capacity has nearly 50% to can not get performance.Copper pipe twines under the situation of small curvature radius in addition, and tube wall easily produces and breaks, and has stayed hidden danger for the leakage of cold-producing medium, reduces the evaporator operation reliability.The latter is stirring cylinder barrel periphery helical form welding fin and overcoat, and cold-producing medium moves in its helical duct and absorbs the heat that cylinder barrel spreads out of.Though its heat transfer property is better, 70% of refrigerating capacity is brought into play, but because of process for making easily makes the mixing drum distortion, it repairs the precision complex process, the cost height, system is not that the reparation of high accuracy inner cavity of cylinder easily causes the cylinder barrel wall to break air-tightness to be destroyed, so the qualification rate of product is lower, influenced production efficiency.

The purpose of this utility model provides a kind of refrigeration system high-efficiency evaporator, and it is simple in structure, handling ease, low cost of manufacture, production efficiency height, refrigeration highly significant.

The purpose of this utility model is achieved in that this device comprises mixing drum and the overcoat thereof that has forward and backward connecting plate and feed pipe, wherein stirs cylinder barrel periphery encapsulation internal thread spiral sleeve pipe, and the tooth top of outer tube thread is airtight with stirring cylinder barrel periphery wall.

Because the utility model adopts riffled tube cylinder formula structure, promptly, form the spirality coolant channel stirring cylinder barrel periphery encapsulation internal thread spiral sleeve pipe.Though this passage also is a spirality, but compare with the helical duct of finned evaporator, its cross section is a toroidal, rather than rectangle, when therefore cold-producing medium moves in passage, fully contact with the cylinder barrel wall, the effective area that carries out heat exchange obviously increases, refrigerating capacity is also with regard to showed increased, and refrigeration naturally also just is better than existing evaporimeter.This device adopts high accuracy cylinder barrel and the internal thread spiral sleeve that the method for suit will be processed in advance to fit together in addition, it is relatively simple for structure, can keep the precision cylinder barrel indeformable in assembling process, therefore can reduce manufacturing cost, because of being easy to produce in batches, so production efficiency is very high.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a kind of concrete structure schematic diagram of the utility model.

Describe concrete structure of the present utility model in detail according to Fig. 1.With the evaporimeter that is used for ice cream maker is example.This device comprises mixing drum 4 and internal thread spiral sleeve pipe 3 etc.Wherein stir and be fixed with the feed pipe 7 that is connected with storagetank on the cylinder barrel 4, two ends be processed with frame with beat the preceding connecting plate 1 that the cake valve body is connected, the back connecting plate 8 that is connected with transmission system.Internal thread spiral sleeve pipe 3 is encapsulated in and stirs cylinder barrel 4 peripheries, and make the tooth top of outer tube 3 threads and cylinder barrel 4 periphery walls airtight, outer tube 3 two ends are enclosed on cylinder barrel 4 periphery walls with side stifled 6, and the pipe that setting is connected with

refrigeration system chews

2,5, make cold-producing medium enter or withdraw from helical duct between cylinder barrel 4 and the outer tube 3 by it, finish the task of cooling.

During use, can utilize this device and refrigeration system to form high-efficiency evaporator separately, also can form high-efficiency evaporator with two or more these devices and refrigeration system.This high-efficiency evaporator can be used for the evaporimeter of above-mentioned ice cream maker, and can be used for raw material again is liquid, and cooled finished product is in the various refrigeration plants of liquid, semisolid or solid.

Claims

1, a kind of refrigeration system high-efficiency evaporator comprises the mixing drum and the overcoat thereof that have forward and backward connecting plate and feed pipe, it is characterized in that stirring cylinder barrel periphery encapsulation internal thread spiral sleeve pipe, and the tooth top of outer tube thread is airtight with stirring cylinder barrel periphery wall.
