Condensed water diversion structure for heat exchanger as well as heat exchanger

Abstract

The invention discloses a condensed water diversion structure for a heat exchanger as well as the heat exchanger. The condensed water diversion structure comprises a main guide structure (31); the main guide structure (31) comprises a water discharging structure and a comb-tooth-shaped inserting piece (312); the comb-teeth-shaped inserting piece (312) has a comb-tooth-shaped side; and the opposite side of the comb-tooth-shaped side is connected with the water discharging structure. With the adoption of the diversion structure, condensed water formed on the heat exchanger flows to the comb-tooth-shaped inserting piece of the diversion structure, and is discharged through the water discharging structure of the diversion structure, so that the condensed water amount at the lower part and the bottom part in the heat exchanger can be reduced; and the phenomena of reducing the heat conduction property of the surface of the heat exchanger caused by the condensed water, increasing power consumption of an air blower, accelerating corrosion, influencing heat exchange effect, damaging the heat exchanger and the like can be avoided; and the good heat exchange condition can be kept.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a condensed water guide structure for a heat exchanger and the heat exchanger. Background technique [0002] Please refer to figure 1 , figure 1 A schematic diagram of the structure of a typical heat exchanger. [0003] The heat exchanger generally includes at least two headers 10, and a number of heat exchange tubes 20 are inserted between the headers 10 to form a heat exchange tube 20 between the two headers 10. Fins 30 are provided for improving the heat exchange effect. When the heat exchanger is used as an evaporator or heat pump heat exchanger, condensed water will be generated on the surface. Generally, when the heat exchanger is used as an evaporator or heat pump heat exchanger, the header 10 of the heat exchanger is as figure 1 If it is placed horizontally as shown, the condensed water can flow down along the length direction of the heat exchange tube 20 , and ...

Problems solved by technology

[0005] When the condensed water flows from the top of the heat exchanger to the middle and lower part, the water will collect in the middle and lower part, and there is a problem that the condensed water cannot be discharged in time, especially at the bottom of the heat exchanger

Condensed water that cannot be discharged in time will not only cause performance problems such as reduced heat transfer performance on the surface of the heat exchanger and increased power consumption of the fan, but also, when the wind speed is high, the condensed water will be blown away from the heat exchanger. Flying water occurs on the leeward side of the bottom of the heat exchanger, and the condensed water will be blown away from the drain pan, contacting metal surfaces such as the fan cover and the floor to accelerate corrosion; in addition, when the temperature of the refrigerant in the heat exchanger is lower than freezing point , if the condensed water cannot be discharged in time, the middle and lower parts of the heat exchanger, especially the bottom, will freeze, and the frozen layer will continue to accumulate, which will further affect the discharge of condensed water and form a vicious circle, resulting in the heat exchange of the heat exchanger. The effect is seriously affected, and when it is more serious, the heat exchanger may be mechanically deformed or even damaged due to the expansion of the ice layer

At the same time, if the condensed water cannot be discharged in time, the heat exchanger will provide a good place for mold to survive and reproduce, and it will threaten people's health when used in air conditioners
