Description

Heat-pipe type refrigerating dehumidifier

The utility model heat pipe-type refrigeration moisture separator is a kind of with the refrigeration moisture-catcher in the box transformer station outside the power supply facilities room.

Though now various box-type substations occur both at home and abroad,, all can not adapt to the weather conditions and the geographical conditions of capricious weather and torrid areas though these box-type substations have its progressive one side than traditional civil engineering transformer station.Utility model " Integrated substation " patent No. 89211012.0, in patent of invention " outdoor all-around protection box type substation " number of patent application 89107136.9 because of having the housing of unidirectional conduction of heat, reasons such as refrigeration dehumidification system are arranged, this transformer station can only be dispelled the heat from inside to outside, and can not conduct heat by ecto-entad, keep inner automatically and under humidity of stipulating and temperature, move.Therefore compare with the home and abroad box-type substation have can any out of doors weather conditions under, under the where reason condition in office, the characteristics moved under any place and the full-load conditions.But what its " refrigeration dehumidification system " or meaning " warm and humid automatic controller " adopted is general heat collector and radiator.Heat conduction is slow, the each point non-uniform temperature on heat collector and the radiator.So its volume is big, cost is high, this is this refrigeration moisture separator link of seizing by the throat, also is the place of " outdoor all-around protection box type substation " blemish in an otherwise perfect thing.

The purpose of this utility model is at the heat conduction problem in the present box-type substation, a kind of heat pipe-type refrigeration moisture separator is provided, adopts heat pipe to make heat collector and radiator, the conductor refrigeration piece is combined with hot pipe technique, be applied in the box-type substation, thereby improved cooling, the effect of drying.

Heat pipe-type refrigeration moisture separator takes following method to realize: heat pipe-type refrigeration moisture separator combines the conductor refrigeration piece with hot pipe technique, adopts heat pipe collector and heat-pipe radiator to obtain good heat-conducting effect.Heat pipe-type refrigeration moisture separator is made of conductor refrigeration piece, cool side heat pipes heat collector, hot side heat radiator, water storage tank, apopore, outlet pipe, power supply.The cool side heat pipes heat collector has heat collector and has heat collector condensation segment, heat collector evaporator section.The hot side heat radiator has radiator evaporator section, radiator condensation segment.The heat pipe collector condensation segment abuts against the cold junction of conductor refrigeration piece, the heat pipe collector evaporator section is equipped with the heat pipe collector heat collecting sheet outward, heat-pipe radiator radiator evaporator section abuts against the hot junction of conductor refrigeration piece, and the heat-pipe radiator fin is equipped with in heat-pipe radiator condensation segment outside.What heat pipe adopted is gravity assisted heat pipe, is divided into two kinds in cool side heat pipes heat collector and hot side heat radiator.Though both are different, structure is basic identical, all makes the cavity of hollow, as the housing of heat pipe, working media acetone or fluorine Lyons is housed in the cavity.Because heat pipe collector is equipped with heat collecting sheet, collector area increases, and fin is housed on the heat-pipe radiator, has increased the surface area of heat radiation.In cool side heat pipes heat collector bottom water storage tank is housed, the water hole is equipped with in the water storage tank bottom, to collect the condensed water of surplus on the cool side heat pipes heat collecting sheet, discharges outside the box-type substation by drainpipe.

Heat pipe-type refrigeration moisture separator volume simple in structure is little, and it is effective to lower the temperature, dry, and just in time meets the requirement of box-type substation.Also since the temperature difference at refrigeration semiconductor piece two ends up to 60 ℃, even atmospheric temperature is changeable, and at temperature difference per day during up to 20～30 ℃, it all has refrigeration to go the function of temperature, outdoor all-around protection box type substation is loaded onto this refrigeration moisture separator, temperature in the box-type substation can more be lower than environment temperature, more can be adapted to the use in the torrid zone, humid tropics, plum rains area, can remove the interior water in air part of box-type substation discharges outside the casing, has the effect of drying, and absorb heat and moisture content in the transformer station, make in the transformer station work of electric switch control element more reliable.Heat pipe-type refrigeration moisture separator is compared with general air-conditioning, and it does not have rotating machinery, reliability, safe.Make and seek the application of hot pipe technique in box-type substation for many years and be achieved.This refrigeration moisture separator also is applicable to silo, places important money and goods, the instrument warehouse uses.

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

Fig. 1 is a heat pipe-type refrigeration moisture separator structural representation.

Have conductor refrigeration piece (1), cool side heat pipes heat collector (2), hot side heat radiator (7), water storage tank (11), apopore (12), power supply with reference to accompanying drawing heat pipe-type refrigeration moisture separator.Heat pipe collector condensation segment (4) abuts against the cold junction that partly causes cold body piece (1), heat-pipe radiator evaporator section (3) directly is connected as a single entity thus with heat pipe collector heat collecting sheet (9), heat-pipe radiator evaporator section (5) abuts against the hot junction of refrigeration semiconductor piece (1), and heat-pipe radiator condensation segment (6) directly is connected as a single entity thus with heat-pipe radiator fin (10).Adopt dividing plate (8) to separate between cool side heat pipes heat collector (2) and the hot side heat radiator (7) during installation, water storage tank (11) is equipped with in cool side heat pipes heat collecting sheet (9) bottom, apopore (12) is equipped with in the water storage tank bottom, discharges outside the casing by drainpipe (13).

After conductor refrigeration piece (1) passes through direct current, produce hot junction (extroversion) and cold junction (introversion).Working media in the cool side heat pipes heat collector (2) evaporates because of the heat on the heat collecting sheet (9) in evaporator section (3) lining.The condensation segment (4) of heat pipe collector (2) abuts against the cold junction of conductor refrigeration piece (1).Because of the low temperature of cold junction makes the condensation of gas in the condensation segment (4) emit the latent heat of vaporization, become liquid and return and steam section (3).Make also approximate low of temperature on each heat collecting sheet (9).Thereby improved the Heat-collecting effect on the heat collector heat collecting sheet (9).

The evaporator section (5) of hot side heat radiator (7) abuts against the hot junction of conductor refrigeration piece (1).Because of the high temperature in hot junction is vaporized the working media of hot side heat radiator (7) in evaporator section (5), this steam is emitted latent heat and condensation at condensation segment (6).Condensation segment (6) is by outwards heat radiation of fin (10), and at this moment temperature on the fin (10) and conductor refrigeration piece (1) hot-side temperature are almost equal, have so also improved the radiating effect of each fin (10).The principle of drying:, the low temperature of conductor refrigeration piece cold junction is equated substantially with temperature on the heat collecting sheet because of the heat conductivility spy of heat pipe is good.Such low temperature makes the moisture content in the air in the transformer station, forms water at first with fixed attention on heat collecting sheet, and water flows into water leg, again outside drainpipe flows out transformer station.Therefore airborne moisture content is less and less in the transformer station, and this airborne absolute humidity is descended, and relative humidity also descends thereupon, and is dry, so the effect of drying.
