Abstract
The utility model discloses a heat exchange aluminum pipe with double-layer heat exchange flow channels. The heat exchange aluminum pipe comprises a flat aluminum pipe body, wherein a plurality of rectangular heat exchange flow channels are arranged inside the flat aluminum pipe body, an upper rectangular heat exchange flow channel and a lower rectangular heat exchange flow channel in each row constitute a group of double-layer heat exchange flow channels, the upper wall face and the lower wall face inside each rectangular heat exchange flow channel are respectively provided with an inner fin, the shapes of the inner fins are the same, the distance between the inner fin on the upper wall face of each rectangular heat exchange flow channel and the left side edge of each rectangular heat exchange flow channel is equal to one fourth the length of the upper edge of each rectangular heat exchange flow channel, and the distance between the inner fin on the lower wall face of each rectangular heat exchange flow channel and the right side edge of each rectangular heat exchange flow channel is equal to one fourth the length of the lower edge of each rectangular heat exchange flow channel. The heat exchange aluminum pipe has the advantages that the rectangular heat exchange flow channels in an up-down double-row structure are matched with a plurality of air current guide holes, a traditional complicated structure with a single flow channel and multiple fins is replaced, internal contact areas and unit flow channels are beneficially increased, production cost consumed by a die is reduced, service life of heat exchangers is prolonged, and production is convenient.
Description
Technical field
The utility model relates to heat exchanger technology, relates in particular to a kind of heat exchange aluminium tube with double-deck heat exchange runner.
Background technology
Heat exchanger tube is one of element of heat exchanger, places within the cylindrical shell, is used for the exchange of heat between two media.Heat exchanger is as a kind of significant element equipment in the industry such as oil refining, chemical industry, environmental protection, the energy, electric power.At present, the aluminium flat conduit that the used for automobile air conditioning heat exchanger adopts, its heat exchange efficiency is substantially up to standard, but under extremely hot environment, especially low-grade car is in view of its reason such as sealing, power, cause the heat exchange of air conditioning for automobiles more and more carrying out in the rugged environment, then heat exchange efficiency is difficult to up to standard.Industrial heat exchange device heat exchange principle is generally refrigerant and flows in the aluminium flat conduit passage, the heat and the flat tube passage that absorb are carried out heat exchange, then carry out heat exchange by aluminium flat conduit and the external world, the factor that determines heat exchange efficiency mainly is contact area and contacting efficiency, existing a lot of heat exchanger channels that adopts single shape, its flow channel shape need to cooperate the flat tube shape and a plurality of fins will be set in each heat exchanger channels, this was so that larger production cost had both been wasted in aluminum pipe processing aspect, and can not guarantee to work long hours simultaneously still can keep unimpeded mobile performance.Therefore, for above aspect, need to make rational improvement.
The utility model content
The purpose of this utility model provides a kind ofly to be had double heat exchanger channels structure up and down, can increase interior contact area and unit runner, is conducive to the heat exchange aluminium tube with double-deck heat exchange runner that improves the heat exchanger life-span, be convenient to produce, with many deficiencies of solution prior art.
The purpose of this utility model is come specific implementation by the following technical programs:
A kind of heat exchange aluminium tube with double-deck heat exchange runner, comprise flat-shaped aluminum pipe body, several rectangle heat exchange runners are offered in described flat-shaped aluminum pipe body inside, each row upper, lower two rectangle heat exchange runners consist of one group of double-deck heat exchanger channels, each rectangle heat exchange runner inside upper, lower two walls are installed respectively an inner fin that shape is identical, wherein be positioned at the inner fin of upper wall surface and the distance on limit, rectangle heat exchange runner left side and equal 1/4th of rectangle heat exchange runner upper edge length, be positioned at the inner fin of lower wall surface and the distance of rectangle heat exchange runner right edge and equal 1/4th of rectangle heat exchange runner lower edge length.The array structure that described rectangle heat exchange runner is two row, seven row distributes.Be provided with a circular air-flow guide hole between per two adjacent row and the row.
The beneficial effect of the heat exchange aluminium tube with double-deck heat exchange runner described in the utility model is: by the some groups of up and down rectangle heat exchange runners of two-row structure are set in flat-shaped aluminum pipe body inside, cooperate some air-flow guide holes, the loaded down with trivial details structure of the many fins of replaceable traditional single channel is conducive to increase interior contact area and unit runner, has reduced the spent production cost of mould, can improves the heat exchanger life-span, is convenient to produce.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is the described heat exchange aluminium tube structure chart with double-deck heat exchange runner of the utility model embodiment.
Among the figure: 1, flat-shaped aluminum pipe body; 2, rectangle heat exchange runner; 3, air-flow guide hole; 4, inner fin.
The specific embodiment
As shown in Figure 1, the described heat exchange aluminium tube with double-deck heat exchange runner of the utility model embodiment, comprise flat-shaped aluminum pipe body 1, the rectangle heat exchange runner 2 that several array structures that are two row, seven row distribute is offered in described flat-shaped aluminum pipe body 1 inside, upper and lower two rectangle heat exchange runners 2 of each row consist of one group of double-deck heat exchanger channels, are provided with a circular air-flow guide hole 3 between per two adjacent row and the row; Upper and lower two walls of each rectangle heat exchange runner 2 inside are installed respectively an inner fin 4 that shape size is identical, being positioned at the inner fin 4 of upper wall surface and the distance on limit, rectangle heat exchange runner 2 left side is 1/4th of rectangle heat exchange runner 2 upper edge length, and being positioned at the inner fin 4 of lower wall surface and the distance of rectangle heat exchange runner 2 right edge is 1/4th of rectangle heat exchange runner 2 lower edge length.
