Abstract
The utility model relates to a fin-type heat exchanger for air conditioners, which belongs to the field of the household appliances. The fin-type heat exchanger of the utility model comprises heat exchanging tubes and fins. A plurality of sets of heat exchanging tubes are respectively embedded in the fins, wherein, the tube cross section of the heat exchanger is oval. Due to the fin-type heat exchanger of the utility model, air can flow among the heat exchanging tubes, and the fin-type heat exchanger of the utility model also can reduce and prevent air flows form flowing around, thereby reducing the energy consumption of the operating of air conditioners and having value to be promoted in the field of household appliances.
Description
Technical field
The utility model relates to a kind of heat exchanger, relates in particular to a kind of idle call finned heat exchanger, belongs to household appliance technical field.
Background technology
For in the market the air-conditioning generally sold, it is the finned heat exchanger that round copper pipe and aluminium sheet fin are formed that its evaporimeter and condenser adopt what all adopt, accounts for most volumes of whole system.As shown in Figure 1: after the air-conditioning entry into service, during the airflow passes pipe rear of fan generation, can produce low velocity eddy region, influence the proper flow of air-flow, and then make the coefficient of heat transfer reduce; Simultaneously, consider from the direction of gas flow that pipe is because the features of shape of its cross section causes bigger resistance, form streaming to a certain degree, the proper flow that has influenced air-flow too reduces the heat exchange amount of acquisition.Therefore, because the existence of above-mentioned defective, the energy consumption when having caused the air-conditioning running increases, and is unfavorable for saving use cost.
Summary of the invention
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of idle call finned heat exchanger is provided.
The purpose of this utility model realizes by following technical solution:
The idle call finned heat exchanger includes heat exchanger tube and fin, and heat exchanger tube is provided with many groups, embeds in the fin, wherein respectively: the body cross section of described heat exchanger tube is oval.
The purpose of this utility model also can further realize by following technical measures:
Above-mentioned idle call finned heat exchanger wherein, is stated the mutual arranged vertical in long limit of the major axis and the fin of described oval heat exchanger tube body cross section.
Advantage of the present utility model is: after adopting the utility model, can guarantee air circulation smoothly between heat exchanger tube, reduce and avoid the situation generation that air-flow streams, improved the coefficient of heat transfer when having increased heat transfer area, therefore energy consumption when having reduced the air-conditioning running on the whole is worth promoting in the art.
The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.

Fig. 1 is that cross section is near the circular flux map of heat exchanger tube (arrow is represented the air-flow trend);
Fig. 2 is a schematic cross-section of the present utility model.
The implication of each Reference numeral is as follows among the figure:

The specific embodiment
Idle call fin 2 heat exchangers as shown in Figure 2, include heat exchanger tube 1 and fin 2, heat exchanger tube 1 is provided with many groups, embeds respectively in the fin 2, its special feature is: the body cross section of described heat exchanger tube 1 is for oval, changed in the prior art understanding for heat exchanger tube 1.Further, the major axis 3 of described oval heat exchanger tube 1 body cross section and the long limit 4 mutual arranged verticals in fin 2 cross sections.
The production process of this idle call fin 2 heat exchangers to increasing rolling technology one as heat exchanger tube 1 round copper pipe, makes it to be shaped to ellipse under the situation that does not increase consumptive material.Thus, make the contact area of interior air-flow of heat exchanger and heat exchanger tube 1 increase, the minimizing air-flow streams the influence with resistance, and air trim is passed through.
Find further combined with the front and back contrast experiment to product: under the same conditions, the heat transfer girth of oval heat exchanger tube 1 is bigger than pipe again, and therefore the thermal resistance in the pipe is little, the heat transfer of medium in helping managing.Simultaneously, its heat transfer area is bigger by 15% than the pipe of same sectional area, and the heat transfer outside a tube amount can improve 15% under identical flow velocity, and oval heat exchanger tube 1 outer average condensation heat transfer coefficient improves 10%～18% with respect to pipe.
By above-mentioned character express as can be seen, after adopting the utility model, can guarantee air circulation smoothly between heat exchanger tube 1, reduce and avoid the situation generation that air-flow streams, improved the coefficient of heat transfer when having increased heat transfer area, therefore energy consumption when having reduced the air-conditioning running on the whole is worth promoting in the art.
Certainly, more than only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the utility model scope required for protection.
