Description

High Efficiency Heat Exchanger

technical field

The utility model relates to the field of heat exchange, in particular to a heat exchanger in air conditioner manufacturing. the

Background technique

The air conditioner evaporator generally uses a finned plate heat exchanger as a heat exchanger. The hot and humid air in the room is cooled by the finned plate heat exchanger. Generated on plate fins. If the condensed water is not drained in time, it will accumulate in large quantities. Due to the relatively small distance between the plates and fins, when a large amount of accumulated cold and warm water frosts into ice, this will cause deformation of the plates and fins, affecting the service life of the air conditioner evaporator; in addition, this will reduce the ribbing coefficient of the evaporator, affecting the cooling effect . In addition, the serpentine tubes used in the prior art are mainly bow-shaped bends, which affect the heat transfer efficiency. the

Utility model content

The purpose of the utility model is to provide a high-efficiency heat exchanger to solve one or more of the above-mentioned existing technical problems. the

The technical solution of the utility model is to provide a high-efficiency heat exchanger, which includes a plurality of fin plates and serpentine tubes passing through the fin plates, the horizontal height of the lower ends of the plurality of fin plates increases successively, and the lower end edges of the fin plates It is installed obliquely, the distance between adjacent finned plates is less than 2mm, and the serpentine tube is a spiral or wave-shaped bent tube. the

The heat exchange device provided by the utility model utilizes the effect of gravity on the condensed water to provide a way to improve the structure of the fin plate of the heat exchanger, so as to prevent the bad influence of the utility model on the heat exchanger due to frosting and icing. Another effect of the utility model is to increase the degree of turbulence of the fluid in the serpentine tube, strengthen the transmission of heat or cold, and improve the heat transfer effect of the heat exchanger. the

In some embodiments, the material of the fin plate is hydrophilic aluminum foil, which further improves the flow guiding effect of the utility model. the

Detailed ways

Below in conjunction with accompanying drawing, the structure of the present utility model is described in further detail. the

As shown in Figure 1, the utility model provides a high-efficiency heat exchanger, which includes a plurality of finned plates 1 and serpentine tubes 2 passing through the finned plates 1, and the horizontal height of the lower ends of the plurality of finned plates 1 increases successively. Large, the lower edge of the finned plate 1 is inclined, the distance between adjacent finned plates 1 of the heat exchanger is less than 2 mm, and the serpentine tube 2 is a spiral or wave-shaped bent tube. The accompanying drawings of the utility model only illustrate the shape of a part of the serpentine tube 2 . the

In the high-efficiency heat exchanger provided by the utility model, since the material of the heat exchanger fin plate 1 is hydrophilic aluminum foil, the condensed water formed on the heat exchanger fin plate 1 will quickly flow down to the heat exchanger under the action of gravity The lower end of the fin plate 1; further, as shown in Figure 2, the edge of the lower end of the fin plate 1 of the heat exchanger is inclined, so that the condensed water flowing to the lower end can be quickly concentrated to the lowest point of the lower end of the fin plate of the heat exchanger. As the condensed water increases, the hanging beads gradually expand; when the distance is less than 2mm, the hanging beads expand to a certain extent and can be transferred to the lower end of the adjacent lower heat exchanger fin plate 1, acting successively to keep the condensed water at the lowest The lower ends of the finned plates 1 of the heat exchanger are concentrated to complete the condensed water diversion work. the

Furthermore, as shown in Figure 1, the high-efficiency heat exchanger improved by the utility model can greatly improve the turbulent flow of the fluid inside the serpentine tube and improve the heat transfer effect because the serpentine tube 2 adopts a spiral or wave-shaped bend. the

The above description is only the preferred mode of the present utility model, and it should be pointed out that those skilled in the art can also make some similar deformations and improvements without departing from the inventive concept of the present utility model. It is regarded as within the protection scope of the present utility model. the
