Problems solved by technology

The condensed water precipitated on the fins can only flow to the lower tube belt surface along the fins, and there is no further downward flow channel, and the condensed water precipitated on the tube belt surface can only stay on the tube belt surface, so Moisture is difficult to drain
If the tube-belt heat exchanger is arranged obliquely toward the direction of air flow during use, although this is conducive to the discharge of condensed water toward the direction of air flow, it will form a large dripping surface, and it is difficult to arrange a condensation that does not affect air flow.

Embodiment Construction

[0011] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0012] Such as figure 1 As shown, the present invention mainly includes pipe strips 1 , fins 2 , water retaining strips 3 , and condensation water channels 4 .

[0013] The inside of the pipe belt 1 contains a plurality of refrigerant flow channels. The fins 2 are arranged in the outer wall channel formed by the bending of the pipe belt 1. The water retaining strip 3 is located at the end of the pipe belt 1 along the direction of air flow. The bottom of the water retaining strip 3 It is integrated with the outer wall surface of the pipe belt 1 and forms a condensate flow channel 4 . The duct belt 1 is inclined downward along the air flow direction, forming an angle β with the horizontal plane; at the same time, it is inclined to the left (or right) side, forming an angle α with the horizontal plane.

[0014] When the low-temperature ref...

Abstract

The pipe belt type room air conditioning evaporator includes pipe belt, fins, water retaining strip and condensed water flow channel. The pipe belt is rightwards or leftwards inclined and downwardsinclinedin the air flow direction. The water retaining strip formed in the end of the air flow channel and the pipe belt form one condensed water flow channel, along which the condensed water separated from the evaporator is exhausted fluently. Compared with conventional pipe belt type heat exchanger, the present invention has only one increased water retaining strip and one altered pipe belt laying angle. The present invention may be used as the evaporator in room air conditioner and is favorable to increasing the heat transferring amount of unit evaporator area and decreasing the size of air conditioner.

Description

Technical field: [0001] The invention relates to an air-conditioning evaporator, in particular to a tube-and-belt type room air-conditioning evaporator using a tube-and-belt heat exchanger as the room air-conditioning evaporator, which belongs to the technical field of air-conditioning. Background technique: [0002] When the room air conditioner is running in cooling mode, the indoor air flows through the evaporator to reduce the temperature. At the same time, because the temperature of the surface of the evaporator is generally significantly lower than the dew point temperature of the air, when the air flows through the surface of the evaporator, part of the moisture in the air will be precipitated, thereby forming condensed water on the surface of the evaporator. Condensed water on the surface of the evaporator should be drained in time. If the condensed water accumulates a lot on the surface of the evaporator, it will block the air passage, increase the flow resistance ...
