Abstract
The utility model relates to a household air conditioner, in particular to a heat exchanger. The utility model aims to provide the heat exchanger made of low cost heat exchange tubes and the low cost heat exchange tubes. The utility model of the heat exchanger is provided U-shape heat exchange tubes, which are arranged into parallels, and metal fins. And the opening ends between each two neighboring U-shape heat exchange tubes are sealed by welding with connecting bends. The heat exchange tube adopts a metal compound structure with copper for the interior tube and aluminum for the exterior tube.
Description
Technical field
The utility model relates to a kind of domestic air conditioner, and concrete is its heat exchanger.
Background technology
Heat exchanger is one of critical piece of domestic air conditioning equipment, and wherein heat-exchange tube all adopts copper material all the time, because copper has mechanical performance preferably, good heat conductivity and corrosion resistance is arranged simultaneously again.But well-known, copper is precious metal, and is higher by its heat exchanger cost of making.
The utility model content
The purpose of the new plough of this practicality provides the heat exchanger that a kind of lower-cost heat-exchange tube is made, and above-mentioned lower-cost heat-exchange tube.
The technical scheme that realizes the utility model purpose is as follows:
A kind of heat exchanger, have " U " type heat-exchange tube and the metal fin of lining up row, and the openend between every adjacent two " U " type heat-exchange tubes all passes through the bridge piece welded seal, and above-mentioned heat-exchange tube adopts metal composite structure, and interior Guan Weitong outer tube is an aluminium.
Be under molten condition, to be composited between the interior pipe of above-mentioned heat-exchange tube and the outer tube.
Above-mentioned heat-exchange tube is composited by pipe and aluminium matter outer tube in copper.
Above-mentioned copper interior pipe of pipe and aluminium matter outer tube are to be composited under molten condition in above-mentioned.
The characteristics of the utility model maximum are to have saved the use amount of copper in the heat exchanger, have guaranteed same function of use simultaneously again; And adopt this multiple tube to save cost greatly, alleviated the weight of heat exchanger.
Accompanying drawing institute is bright
Fig. 1 is the front view of the utility model heat exchanger.
Fig. 2 is an A place enlarged diagram among Fig. 1.
The specific embodiment
See Fig. 1, floor map for the utility model heat exchanger, wherein heat-exchange tube 1 is " U " type, form a line up and down, openend passes through bridge piece 3 welded seals all towards the figure right side of face between each two adjacent heat-exchange tube 1, metal fin 2 and every heat-exchange tube interlocking, the even spaced and parallel of direction along heat-exchange tube is arranged, and has mounting bracket 4 at above-mentioned heat exchanger two ends, is used for fixing on the air-conditioner.
See Fig. 2, for the section of heat-exchange tube 1 sends out schematic diagram big, wherein in pipe 11 be copper material, outer tube 12 is an aluminum material, the interior pipe of above-mentioned heat-exchange tube and outer tube are to be composited under molten condition, have copper, the aluminium atom mixed layer of 2-3 micron between the inner and outer pipes.
Obviously, above-mentioned embodiment only is to realize one of multiple mode of the present utility model, as long as heat exchanger is to adopt copper aluminum composite pipes to be processed into no matter how its shape changes equally in the included scope of the invention.
Claims (4)
