The water leakage prevention structure comprises an integrated support and a water retaining cofferdam. According to the utility model, the flange around the integrated bracket completely wraps the bearing beam in the middle of the top of the container, so that raining rainwater cannot enter the indoor side of the indirect evaporation cooling air conditioning unit; the lower edge of the air-to-air heat exchanger is totally enclosed by the water retaining cofferdam, the water retaining cofferdam is in contact with and fixed to the heat exchanger bearing beam, and the water retaining cofferdam is nested in the spraying water receiving disc, so that spraying water only can be in contact with the water retaining cofferdam and the spraying water receiving disc, abutted seams among multiple structures are reduced, the spraying water is prevented from being in direct contact with the abutted seams, and the spraying efficiency of the air-to-air heat exchanger is improved. And even if certain water leakage exists, the water retaining cofferdam can hold water, so that the problem that indoor side spraying water flows disorderly due to water leakage of the indirect evaporation refrigeration air conditioning unit is avoided.

Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of indirect evaporative cooling unit, especially to a water leakage prevention structure of indirect evaporative cooling unit. BACKGROUND

[0002] In the current data center industry, in order to reduce the heat dissipation energy consumption, the indirect evaporative cooling air conditioning unit is usually used for refrigeration, but the current indirect evaporative cooling air conditioning unit has high water leakage risk and difficult water leakage treatment, especially near the metal structure above the air-air heat exchanger and the connection joint gap around the spray water pan and the air-air heat exchanger.

[0003] The sealing mode around the condenser and the spray water distributor of the current indirect evaporative cooling air conditioning unit is that the condenser and the water distributor are placed on the support, then the support is fixed on the container, finally the frame is sealed by the metal sealing plate, which can easily make the spray water and the rainwater penetrate into the indoor side of the indirect evaporative cooling air conditioning unit through the gap between the support and the container and the gap between the support and the metal sealing plate; below the air-air heat exchanger, the air-air heat exchanger is directly installed on the heat exchanger fixed cross beam, and the spray water pan is also directly fixed on the heat exchanger support cross beam, which can make the joint gap of many structure parts soaked in the spray water, resulting in water leakage, thereby affecting the supply air humidity of the indirect evaporative cooling air conditioning unit, and can cause serious problems such as server short circuit.

[0004] Therefore, it is necessary to develop a water leakage prevention structure of indirect evaporative cooling unit to solve the above problems. UTILITY MODEL CONTENTS
