Description
Technical field
The utility model belongs to field of air conditioning, relates in particular to a kind of heat exchanger and has its air-conditioner outdoor unit.
Background technology
Air-conditioner, after long-term operation, because outdoor environment is complicated and changeable and uncontrollable, causes household air-conditioner decay serious, and the air conditioner refrigerating heating capacity after long-term use is than new air-conditioning variation.Cause the reason of variation to mainly contain the heat exchanger dust stratification in off-premises station, heat exchanger materials metal erosion etc.As shown in Figure 1, heat exchanger comprises heat exchanger tube and heat exchange fin, and dust stratification heat exchanger performance impact is very large, and the dust that is accumulated in heat exchanger surface affects the coefficient of heat transfer of heat exchanger on the one hand, increases windage on the one hand, causes air quantity to reduce, and heat exchange amount reduces.
Utility model content
The utility model provides a kind of heat exchanger and has its air-conditioner outdoor unit, and object is to reduce dust stratification, improves heat exchange property.
To achieve these goals, the technical scheme that the utility model is taked is:
A kind of heat exchanger of the present utility model, comprises heat exchange fin and heat exchanger tube, on the leeward side of described heat exchange fin, described in adjacent two, between heat exchanger tube, is being provided with abat-vent.
Described abat-vent be positioned at adjacent two described in heat exchanger tube centre position place.
Described abat-vent is strip and the deep bead parallel with described heat exchanger tube.
The width dimensions of described deep bead is between between 0.8 times to 1.5 times of described heat exchanger tube diameter.
Vertical range between the edge of described deep bead and adjacent described heat exchanger tube is not less than 0.5 times of heat exchanger tube diameter.
The material of described deep bead is metal.
The material of described deep bead can also be plastics.
The utility model also provides a kind of air-conditioner outdoor unit, comprises above-mentioned heat exchanger.
The heat exchanger that the utility model provides, by the leeward side of heat exchange fin, abat-vent being set, and is located at abat-vent between adjacent two heat exchanger tubes, in the time of air-conditioner start running, air current flow, is subject to the impact of abat-vent, and air-flow forms vortex in abat-vent place reverse flow, the air-flow of disturbance can blow to the dust stratification of heat exchanger tube leeward side, can reduce the gathering of dust, thereby reduce windage, increase the coefficient of heat transfer, and then improve the long-acting heat transfer effect of heat exchanger, more energy-conservation.

Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail, and object is to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present utility model, technical scheme, and contributes to its enforcement.
In order to solve the problem of prior art existence and to overcome its defect, reduce the dust stratification on the heat exchanger tube in air-conditioner outdoor unit, improve the heat exchange property of heat exchanger, the technical scheme that the utility model is taked is:
As shown in Figure 2, a kind of heat exchanger of the utility model, comprises heat exchange fin 2 and heat exchanger tube 1, and heat exchanger tube 1 is copper pipe, on the leeward side 21 of heat exchange fin 2, between adjacent two heat exchanger tubes 1, is also provided with abat-vent 3.In the time of air-conditioner start running, air current flow, is subject to the impact of abat-vent 3, air-flow forms vortex in abat-vent 3 place's reverse flow, and the air-flow of disturbance can blow to the dust stratification of heat exchanger tube 1 leeward side, thereby can reduce the gathering of dust, improve the long-acting heat transfer effect of heat exchanger, more energy-conservation.
Specifically, abat-vent 3 is to be positioned at adjacent two heat exchanger tube 1 centre position places.As shown in the figure, in the present embodiment, heat exchanger is provided with two heat exchanger tubes 1, abat-vent 3 is positioned at the centre position place of upper and lower two heat exchanger tubes 1, and in this position, abat-vent 3 has good shunting effect, the throughput that makes to flow to adjacent two heat exchanger tube 1 leeward sides is roughly equal, improves dust removing effects.
Abat-vent 3 is the deep bead of a strip, and deep bead is the state parallel with heat exchanger tube 1 and is fixedly mounted on heat exchange fin 2.The length of the length of deep bead and heat exchanger tube 1 is roughly equal, to guarantee that the dust that heat exchanger tube 1 is assembled in whole length can both be blown off.
As shown in Figure 3, the thinner thickness of deep bead, the width dimensions of deep bead is that between 0.8 times to 1.5 times between heat exchanger tube 1 diameter, in figure, A span is between 0.8D～1.5D, D is the diameter of heat exchanger tube 1.Vertical range between the upper and lower edge of deep bead and upper and lower side heat exchanger tube 1 is not less than 0.5 times of heat exchanger tube 1 diameter, and in figure, the value of B is not less than 0.5D.The width dimensions of deep bead and setting according to aforementioned requirement apart from the distance between heat exchanger tube 1, not only make it there is the larger area that keeps out the wind, guarantee to there is enough throughputs and can blow to the leeward side of heat exchanger tube 1, and distance between deep bead and heat exchanger tube 1 is unlikely to again, compared with little and cause producing larger windage, to guarantee to flow through the airflow smooth of heat exchanger.
The material of deep bead can be metal, can adopt the mode of welding to be fixed on heat exchange fin 2, can certainly adopt other fixed form.Deep bead can also adopt other material to make, as plastics etc.
As distortion embodiment, as shown in Figure 4, on heat exchange fin 2, not only between adjacent two heat exchanger tubes 1, abat-vent 3 can be set, the upper side position place that can also be positioned at heat exchanger heat exchanger tube 1 topmost on heat exchange fin 2 respectively arranges abat-vent 3 with the lower position place that is positioned at heat exchanger tube 1 bottom, even if heat exchanger tube 1 is between adjacent two abat-vents 3, and abat-vent 3 is equidistant setting on heat exchange fin 2, can reduce like this dust stratification of heat exchanger heat exchanger tube 1 and bottom on whole leeward side topmost.
The utility model also provides a kind of air-conditioner outdoor unit, comprises above-mentioned heat exchanger, and the concrete structure of heat exchanger can, with reference to Fig. 2 to Fig. 4, not repeat them here.Because the utility model air-conditioner outdoor unit comprises the heat exchanger in above-described embodiment, so it has all advantages of above-mentioned heat exchanger.
As distortion embodiment, abat-vent 3 can also be fixed on the shell of off-premises station.
Below by reference to the accompanying drawings the utility model is exemplarily described.Obviously, the utility model specific implementation is not subject to the restrictions described above.As long as having adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; Or without improvement, above-mentioned design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
