Description
Technical field
The present invention relates to a kind of water supercooling apparatus realizing supercool water law stability and high efficiency ice making, especially carry
High cold-producing medium operating temperature, reduces the Low Temperature Thermal tubular type subcooler of heat transfer temperature difference.
Background technology
Dynamic ice cold-storage technology is one significant development direction of world today's central air-conditioning, is situated between with ice for accumulation of energy
Matter, utilizes peak load poor, peak load shifting, reduces installed capacity of power station, saves operating cost, it is achieved
Doulbe-sides' victory.The core of dynamic ice cold-storage technology is that continuous high-efficient stablizes preparing ice slurry, reduces refrigeration working medium and quilt
The heat transfer temperature difference of cold flow body, improves operational efficiency.
At present, known apparatus for supercooling is that the material such as copper, aluminum is fabricated by according to solid conductive heat principle
Shell-and-tube heat exchanger or plate type heat exchanger, refrigeration working medium flows through subcooler pipeline side, by cold fluid flow
Through cooler pipeline opposite side, carry out heat exchange by the mode such as convection current, heat conduction.But, it is limited to solid
Body heat conductivity, the heat conductivity of copper is about 400w/(m K), the heat conductivity of aluminum is about 200w/
(m K), for making to be reached-2 DEG C by cold flow body, it is achieved supercool, the temperature of refrigeration working medium is the most at least required to be
-5 DEG C, at this temperature, the operating mode of compressor is poor, inefficient.
Summary of the invention
The operating mode too low in order to improve existing subcooler refrigeration working medium side temperature, overcomes compressor efficiency
Relatively low deficiency, the present invention provides a kind of Low Temperature Thermal tubular type subcooler, and this subcooler can be by work of freezing
The operating temperature of matter side improves 1～2 DEG C, i.e. refrigeration working medium operating temperature improves to-3 DEG C from-5 DEG C, it is achieved
Little temperature difference heat exchange, it is ensured that water is supercool stable.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Low Temperature Thermal tubular type subcooler,
Including housing, have heat exchange element to arrange wherein in the housing, cold-producing medium flows through side, by cold fluid flow
Through opposite side, being provided with the heat pipe of uniform fine and closely woven distribution in described housing, the arragement direction of heat pipe is with cold
Water (flow) direction is vertical, and housing tip and bottom are respectively equipped with refrigerant inlet, refrigerant outlet and by cold flow
Body import, by cold fluid outlet, cold end and the hot junction of heat pipe are separated by the insulating barrier being located in housing.
In subcooler, replace copper pipe, copper coin to carry out heat exchange with special heat pipe, cold-producing medium with by cold flow body
Flowing separately through heat pipe two ends, centre separates with thermal baffle.
Heat pipe is carried out smooth treatment by cold flow body side surface, it is ensured that water is stablized supercool.
Heat pipe is the heat transmission equipment made with gas-liquid phase transition principle, and heat exchange efficiency exceeds ordinary solid heat conduction material
Material hundred times, can realize good heat exchange under the temperature difference of 1 DEG C.Refrigeration working medium passes through respectively with by cold flow body
Heat pipe two sections carries out heat exchange, it is achieved under the little temperature difference water stablize supercool.Special heat pipe is satisfied prevents water
Supercool icing demand, heat pipe is by cold flow body side surface smooth treatment (polishing, pickling etc.).
Surface of shell carries out smooth treatment, one layer of hydrophobic material (such as politef) of surface attachment, increases
Adding degree of supercooling, anti-stagnant ice is tied.
The invention has the beneficial effects as follows, uniform and stable supercool under the conditions of, it is achieved the little temperature difference of subcooler
Heat exchange, improves refrigeration working medium operating temperature, is effectively improved working conditions of compressor, improves efficiency.
