Abstract
The utility model relates to an evaporator for a wall mounting type air conditioner, in particular to an aluminum integral type corrugated finned tube evaporator, which comprises two side plates, finned tube bundles, transition joints, transition tubes, a coolant input tube and a coolant output main tube, wherein the two side plates are used for fixing a plurality of dispersed finned tube bundles so that the finned tube bundles are overlapped into a whole; a coolant inlet and a coolant outlet are respectively arranged on two ends of each finned tube bundle; the inlet and the outlet transition tubes are connected with the inlet and the outlet of the finned tube bundle by the transition joints; all inlet transition tubes are finally converged into the coolant input tube; and all outlet transition tubes are finally converged into the coolant output main pipe. During working, a coolant enters through the input tube, and then is converged into the output main tube after performing heat exchange with outside air through each flow in the evaporator. In the aluminum integral type corrugated finned tube evaporator of the wall mounting type air conditioner, the evaporator adopting the aluminum integral type bending corrugated finned tube with high heat transfer efficiency replaces an evaporator in a tube sheet type structure formed by a copper tube and aluminum fins of a wall mounting type air conditioner, so that the defects that the expanded aluminum tube is easy to crack and is unable to bear pressure in a tube expanding technology by singly using the aluminum tube to replace the copper tube are overcome, the generation of contact thermal resistance between the heat transfer tube and the fin is avoided, and the same effect of using the copper tube is realized. The evaporator has a simple structure and fewer process flows, reduces the manufacturing cost of the air conditioner by using aluminum to replace copper, has the advantages of small contact thermal resistance.
Description
Technical field
The utility model wall-hanging air conditioner aluminium matter monoblock type corrugated fin pipe evaporator is applicable to family expenses wall-hanging air conditioner evaporimeter, belongs to the air-conditioner technical field of heat exchange.
Background technology
At present, family expenses wall-hanging air conditioner 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 bend pipe and the heat pipe that direct transfers 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 wall-hanging air conditioner evaporimeter, be the direction that the air-conditioning manufacturing industry is extremely paid close attention to always.China's bauxite resource is abundanter, and the price of aluminium is lower, and aluminium and copper are in the similitude that has material aspect the refrigeration heat conduction.But because aluminium plasticity not as copper material, adopts the full aluminium wall-hanging air conditioner of traditional expansion tube process manufacturing evaporimeter to be difficult to guarantee the sealing of aluminum pipe, the novel full aluminum evaporation device structure of development wall-hanging air conditioner helps technological progress and the development of air conditioner industry aluminium for copper.
The utility model content
This utility model wall-hanging 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 wall-hanging air conditioner of copper pipe and aluminium fin.The specific embodiment is as follows:
This wall-hanging 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, refrigerant input pipe and refrigerant output are 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 final refrigerant input pipe that imports is taken in the import transition, all the output of the final remittance of outlet transition adapter refrigerant is responsible for, refrigerant is entered by input pipe 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 time bending of a monoblock type corrugated fin pipe process odd number and constitutes, the finned tube bending part does not have fin, whole bending and molding, refrigerant passage import and export non-finned, be convenient to side plate fixing with being connected of transit joint.Each finned-tube bundle can be used as a refrigerant flow path, determines the quantity of the finned-tube bundle of stack 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, input pipe and output are responsible for and are 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 wall-hanging air conditioner evaporimeter.
The utility model wall-hanging 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, avoided producing 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.
