Abstract
The utility model relates to an evaporator of a cabinet air conditioner, in particular to an aluminum integral corrugated finned tube evaporator. The evaporator comprises two side plates, finned tube bundles, transition connectors, transition connecting tubes, a refrigerant input main tube and a refrigerant output main tube, wherein the two side plates are used for fixing a plurality of the decentralized finned tube bundles to ensure that the finned tube bundles are overlapped to form a whole body; a refrigerant inlet and a refrigerant outlet are respectively formed at two ends of each finned tube bundle; the inlet and outlet transition connecting tubes are connected with inlets and outlets of the finned tube bundles through the transition connectors; all the inlet transition connecting tubes are finally connected with the refrigerant input main tube; and all the outlet transition connecting tubes are finally connected with the refrigerant output main tube. During work, the refrigerant enters from the input main tube and then influxes into the refrigerant output main tube after conducting heat transfer with outside air in the evaporator by various procedures. The evaporator adopts aluminum integral corrugated finned tubes with high heat transfer efficiency to replace a copper tube and aluminum fin hanging type air conditioner evaporator, overcomes the disadvantage that when tube expanding process is adopted by merely replacing copper tubes with aluminum tubes, the aluminum tubes have cracks and can not withstand pressure after tube expanding, and avoids thermal contact resistance produced between heat transfer tubes and fins, thereby achieving the same effect with using the copper tubes. The evaporator has the advantages that the structure is simple, the process flow is less, the manufacture cost of the air conditioner is reduced through replacing copper with aluminum, simultaneously the thermal contact resistance is small, the heat transfer coefficient is high.
Description
Technical field
The utility model cabinet air conditioner aluminium matter monoblock type corrugated fin pipe evaporator is applicable to household cabinet air-conditioning device evaporimeter, belongs to the air-conditioner technical field of heat exchange.
Background technology
At present, household cabinet air-conditioning device evaporimeter mostly is pipe sheet type structure greatly, adopt expand tube to be connected between heat-transfer pipe and the fin, heat-transfer pipe is a copper pipe, and fin is the aluminium fin, and the evaporimeter two ends adopt the heat-transfer pipe of bending and the straight tube that passes fin to link together by soldering, form the sealing runner, cold-producing medium is responsible for through inlet and is entered, and is responsible for by outlet and flows out, and realizes the heat exchange of cold-producing medium and air.Copper heat-transfer pipe thermal conductivity factor height, plasticity is good, is easy to realize expand tube.China produces more than 9,000 ten thousand air-conditioners per year at present, account for more than 70% of world's air-conditioner output, the a large amount of copper materials of annual consumption, air conditioner industry becomes China consumption copper rich and influential family, and the scarcity of China's copper resource adds that the copper price is about three times of aluminium price, and the direct cost of copper pipe has accounted for about 50% of separate unit air-conditioning production cost in the air-conditioning, for the development of the substitute of copper pipe in the air-conditioner evaporator, be the direction that the air-conditioning manufacturing industry is extremely paid close attention to always.Because the similitude of aluminium and copper material aspect refrigeration heat conduction, and the price of aluminium is lower, China's bauxite resource is abundanter, but because aluminium plasticity is not as copper material, adopt the full aluminium air-conditioner evaporator of traditional expansion tube process manufacturing to be difficult to guarantee the sealing of aluminum pipe, the novel full aluminum evaporation device structure of development air-conditioner helps technological progress and the development of air conditioner industry aluminium for copper.
The utility model content
This utility model cabinet air conditioner aluminium matter monoblock type corrugated fin pipe evaporator is intended to not increase under the prerequisite of evaporimeter volume, adopts the high aluminum monoblock type corrugated fin pipe of heat transfer efficiency to replace the evaporimeter of the pipe sheet type structure air-conditioner of copper pipe and aluminium fin.The specific embodiment is as follows:
This aluminium matter monoblock type corrugated fin pipe evaporator adopts the finned-tube bundle overlaying structure, include the both sides side plate, finned-tube bundle, transit joint, transition is taken over, the refrigerant input is responsible for and refrigerant output is responsible for, wherein, the finned-tube bundle that the both sides side plate is used for fixing several dispersions makes it to be superimposed as a whole, the refrigerant entrance and exit is respectively at each finned-tube bundle two ends, advance, advancing by transit joint and finned-tube bundle taken in the outlet transition, outlet links to each other, all the input of the final remittance of import transition adapter refrigerant is responsible for, all the output of the final remittance of outlet transition adapter refrigerant is responsible for, refrigerant is responsible for by input and is entered during work, imports output and be responsible in evaporimeter after each flow process and outside air heat exchange.
Described finned-tube bundle, it is characterized in that: each finned-tube bundle is snakelike parallel arranged by the bending of a monoblock type corrugated fin pipe and constitutes, import and export and the bending part non-finned, be convenient to side plate fixing with being connected of transit joint, import and export are towards being determined by bending times, each finned-tube bundle is determined the quantity of the finned-tube bundle of stack as a refrigerant flow path according to refrigerant flow path quantity.
Described fin-tube integral type is characterized in that: the aluminium matter heat-transfer pipe of collection refrigerant runner pipe and fin one, refrigerant runner pipe section is the rectangle flat tube, transversely arranged 4～7 length-width ratios are 1～10 rectangle concurrent flow passage in the refrigerant runner pipe, rectangle concurrent flow passage helps strengthening the interior heat transfer of passage and reduces the heat transfer medium flows resistance, spaced-apart between the concurrent flow passage, on concurrent flow passage outside, the lower surface axially-aligned has corrugated fin, spacing of fin is 1.1～3.0mm, fin is thick to be 0.06～0.2mm, two corrugation pitches of fin are 3～20mm, and corrugated fin helps augmentation of heat transfer.This monoblock type corrugated fin pipe has compact fin structure, less thermal contact resistance, bigger heat transfer area, has improved the heat transfer efficiency of evaporimeter significantly, has increased heat transfer coefficient.
Described transit joint, transition adapter, refrigerant input are responsible for and the refrigerant output person in charge is aluminum pipe, and its wall thickness is 1.5 times of pipe type air-conditioning copper pipe wall thickness, and bearing capacity satisfies the requirement of air-conditioner evaporator.
The utility model cabinet air conditioner aluminium matter monoblock type corrugated fin pipe evaporator, overcome when substituting copper pipe employing expansion tube process with aluminum pipe merely and be prone to the shortcoming that crackle is unable to born and pressed behind the aluminum pipe expand tube, overcome the thermal contact resistance between heat-transfer pipe and the fin, the heat transfer efficiency height, thus reach and the same effect of use copper pipe.Simultaneously, reduce manufacturing cost of air conditioner, alleviated air-conditioner weight.
