Abstract
The utility model relates to a low temperature heat pipe type sub-cooler which comprises a shell body. Heat exchanging elements are distributed in the shell body, refrigerating fluid flows through one side of the shell body, refrigerated fluid flows through the other side of the shell body, heat pipes which are distributed evenly and densely are arranged inside the shell body, the arranging direction of the heat pipes is perpendicular to the flowing direction of the refrigerated fluid, a refrigerating fluid inlet and a refrigerated fluid outlet are formed in the top end of the shell body, a refrigerating fluid outlet and a refrigerated fluid inlet are formed in the bottom end of the shell body, and the cold ends of the heat pipes and the hot ends of the heat pipes are separated by insulating partition boards in the shell body. The low temperature heat pipe type sub-cooler improves the working condition that the temperature of refrigerating working mediums of an existing super-cooler is too low, overcomes the defect that the efficiency of a compressor is low and effectively enables the temperature of the refrigerating working mediums to be effectively increased by 1-2 DEG C on the premise that water is super-cooled stably. The arrangement of the specially-made heat pipes replaces the arrangement of traditional heat exchanging elements (copper pipes or copper plates), the working temperature of the refrigerating mediums is increased on the premise that water is super-cooled stably, meanwhile, the working condition of the compressor is improved and small temperature difference and high heat exchange are realized.
Description
Technical field
The utility model relates to a kind of water supercooling apparatus of realizing the ice making of subcooled water method stability and high efficiency, especially improves cold-producing medium operating temperature, dwindles the Low Temperature Thermal tubular type subcooler of heat transfer temperature difference.
Background technology
Dynamic ice cold-storage technology is significant development direction of world today's central air-conditioning, take ice as accumulation of energy medium, utilizes peak load poor, and peak load shifting reduces installed capacity of power station, saves operating cost, realizes doulbe-sides' victory.The core of dynamic ice cold-storage technology is that continuous high-efficient is stablized preparing ice slurry, dwindles refrigeration working medium and by the heat transfer temperature difference of cold fluid, improves operational efficiency.
At present, known apparatus for supercooling is shell-and-tube heat exchanger or the plate type heat exchanger that the materials such as copper, aluminium form according to the manufacture of solid conductive heat principle, refrigeration working medium subcooler pipeline one side of flowing through, through cooler pipeline opposite side, is carried out heat exchange by modes such as convection current, heat conduction by cold fluid flow.But, be limited to Solid thermal conductivity, the thermal conductivity factor of copper is about 400w/(mK), the thermal conductivity factor of aluminium is about 200w/(mK), for making to be reached-2 ℃ by cold fluid, realized coldly, the temperature of refrigeration working medium is generally at least required to be-5 ℃, at this temperature, the operating mode of compressor is poor, and efficiency is lower.
Summary of the invention
In order to improve the too low operating mode of existing subcooler refrigeration working medium side temperature, overcome the deficiency that compressor efficiency is lower, the utility model provides a kind of Low Temperature Thermal tubular type subcooler, this subcooler can improve 1～2 ℃ by the operating temperature of refrigeration working medium side, be that refrigeration working medium operating temperature is increased to-3 ℃ from-5 ℃, realize little temperature difference heat exchange, guarantee that water crosses cold stable.
The utility model solves the technical scheme that its technical problem adopts: a kind of Low Temperature Thermal tubular type subcooler, include housing, in housing, there is heat exchange element to arrange wherein, the cold-producing medium side of flowing through, by cold fluid flow through opposite side, in described housing, be provided with the heat pipe of even fine and closely woven distribution, the arragement direction of heat pipe is with vertical by cold water flow path direction, housing top and bottom are respectively equipped with refrigerant inlet, refrigerant outlet and by cold fluid import, exported by cold fluid, the cold junction of heat pipe and hot junction are separated by the insulating barrier being located in housing.In subcooler, with special heat pipe, replace copper pipe, copper coin to carry out heat exchange, cold-producing medium and the heat pipe two ends of being flowed through respectively by cold fluid, centre separates with thermal baffle.
Heat pipe is carried out smooth treatment by cold fluid side surface, guarantees that water stablized cold.
Heat pipe is the heat transmission equipment made from gas-liquid phase transition principle, and heat exchange efficiency exceeds common solid conductive heat material hundred times, under the temperature difference of 1 ℃, can realize good heat exchange.Refrigeration working medium with by cold fluid, by two sections of heat pipes, carried out exchange heat respectively, realize stablizing of water under the little temperature difference cold.Special heat pipe meets anti-sealing and crosses cold junction ice demand, and heat pipe is by cold fluid side surface smooth treatment (polishing, pickling etc.).
Surface of shell carries out smooth treatment, and surface attachment one deck hydrophobic material (as polytetrafluoroethylene (PTFE)) increases degree of supercooling, anti-stagnant ice knot.
The beneficial effects of the utility model are, uniform and stable, cross under cool condition, realize the little temperature difference heat exchange of subcooler, improve refrigeration working medium operating temperature, effectively improve working conditions of compressor, raise the efficiency.
Accompanying drawing explanation
Fig. 1 is system schematic of the present utility model.
1. refrigerant inlet in figure, 2. housing, 3. heat pipe, 4. refrigerant outlet, 5. thermal baffle, 6., by cold fluid import, is 7. exported by cold fluid.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
In Fig. 1, a kind of Low Temperature Thermal tubular type subcooler, include housing 2, in housing 2, have heat exchange element to arrange wherein, the cold-producing medium side of flowing through, by cold fluid flow through opposite side, in housing 2, be provided with the heat pipe 3 of even fine and closely woven distribution, the arragement direction of heat pipe 3 is vertical with water (flow) direction, and housing 2 tops and bottom are respectively equipped with refrigerant inlet 1, refrigerant outlet 4 and by cold fluid import 6, by cold fluid outlet 7, the cold junction of heat pipe 3 and hot junction are separated by the insulating barrier 5 being located in housing 2.Heat pipe 3 by cold flow side polish, the smooth treatment such as pickling, cold-producing medium flows into from refrigerant inlet 1, after heat pipe 3 heat exchange, temperature raises, from refrigerant outlet 4, flow out, by cold fluid from being flowed into by cold fluid import 6, after heat pipe heat exchanging, temperature reduces, from being flowed out by cold fluid outlet 7.Housing 2 smooth surfaces are processed, and adhere to one deck hydrophobic material (as polytetrafluoroethylene (PTFE)).Heat pipe 3 is carried out smooth treatment by cold fluid side surface, guarantees that water stablized cold.
