Abstract

The utility model relates to heat exchange pins of a condenser, which comprise a left sealing strip, a right sealing strip and fins installed between the left sealing strip and the right sealing strip. The fins are arranged horizontally, gas channels of the fins are located at the mutually staggered positions, and the flowing direction of condensed gas from an inlet to an outlet is perpendicular to the flowing direction of gas in each fin. The heat exchange fins of the condenser effectively improve heat exchange coefficient, and prolong heat exchange time. Compared with the prior art, the heat exchange coefficient is increased by one time, and heat exchange effect is improved.

Description

The condenser heat exchange fin

Technical field

The utility model relates to art of refrigeration units, especially the condenser heat exchange fin.

Background technology

The principle of freon condenser is carried out heat exchange for the compressed air with the liquid freon of high pressure and another passage, thereby reaches the purpose of cooled compressed air, and freon also is vaporizated into gas because of the absorption heat.In this heat exchanger because the freon flow is little, need be in passage disturbance constantly could realize the heat exchange with air.As shown in Figure 1; Original structure comprises left strip of paper used for sealing 101, right strip of paper used for sealing 103, fin 102, and when the freon fluid flows in the fin 102 that respectively communicates, its flow direction is consistent with the orientation and the channel direction of fin 102; Because fin 102 does not stop each other; Rate of flow of fluid is accelerated, and shortens heat-exchange time, and the disturbance that the fin convection cell produces is smaller; And because the restriction of fin die processing, originally to increase the mode of heat exchange area very limited and die cost is very high through reducing the fin pitch.

The utility model content

Shortcomings such as the applicant is shorter to heat-exchange time in the above-mentioned existing structure, and disturbance is less provide a kind of structure more reasonable, heat exchange obvious results condenser heat exchange fin, thus improved its coefficient of heat transfer, prolong heat-exchange time.

The technical scheme that the utility model adopted is following:

A kind of condenser heat exchange fin; Comprise between left strip of paper used for sealing, right strip of paper used for sealing, the left and right sides strip of paper used for sealing fin is installed; Fin is transversely arranged, and the gas passage of each fin laterally is being in interlaced position, and the circulating direction of the gas that is condensed from import to outlet is vertical with the circulating direction of gas each fin.

The beneficial effect of the utility model is following:

Through change fin placement direction, make freon fluid heat-exchange time in the heat exchanger of equal volume more lasting, disturbance is more abundant, makes one times of coefficient of heat transfer increase nearly, effectively raises the heat exchange effect, and does not increase cost.

Description of drawings

Fig. 1 is the front view of existing condenser heat exchange fin.

Fig. 2 is the front view of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described.

As shown in Figure 2; The described condenser heat exchange fin of the utility model comprises installs fin 2 between left strip of paper used for sealing 1, right strip of paper used for sealing 3, the left and right sides strip of paper used for sealing; Fin 2 is transversely arranged; The gas passage of each fin 2 laterally is being in the interlaced position that communicates, and the circulating direction of the gas that is condensed from import to outlet is vertical with the circulating direction of gas each fin.

Arrow is represented the freon fluid flow direction among Fig. 2.

In the course of work, after freon fluid a gets into fin, flow in the adjacent fins 2 in the gap through fin 2 two ends incision face when flowing; Produce fluid a1, a2, a3 horizontal and vertically continuous conversion in the flow process, fluid is fully disturbance in each fin, compared with prior art; Fluid flow length nearly doubles; Thereby make fluid fully disturbance in fin 2 passages, prolonged heat-exchange time, reached the purpose of abundant heat exchange.

More than describing is the explanation to the utility model, is not the qualification to utility model, and the utility model institute restricted portion is referring to claim, and under situation about conceiving basically without prejudice to the utility model, the utility model can be done any type of modification.

Claims

1. condenser heat exchange fin; Comprise between left strip of paper used for sealing, right strip of paper used for sealing, the left and right sides strip of paper used for sealing fin is installed; It is characterized in that: said fin is transversely arranged; The gas passage of each fin laterally is being in interlaced position, and the circulating direction of the gas that is condensed from import to outlet is vertical with the circulating direction of gas each fin.
