Evaporation cooling/air cooling heat exchange composite type condenser

Abstract

The invention discloses an evaporation cooling / air cooling heat exchange composite type condenser. The evaporation cooling / air cooling heat exchange composite type condenser consists of a fan, an aircooling heat exchanger, a spraying system, a water retaining plate, cooling fillers, shutters, a water collecting tray, a circulating water pump and a water cooling heat exchanger. The condenser is mainly applicable to the fields requiring cooling in a whole year and can be flexibly switched between two running modes according to changes of seasons, namely an air cooling mode and an evaporation cooling mode. The evaporation cooling / air cooling heat exchange composite type condenser disclosed by the invention overcomes the problems such as surface scaling and corrosion of a heat exchanger pipein a traditional condenser by adopting a way that each heat exchangers is separated from a spraying device, also further improves the running performances by overcooling a refrigerant by fully utilizing the cold of the spraying water by virtue of a helical plate heat exchanger, has the characteristics of being compact in structure, small in floor area, high in heat transfer efficiency, high in operation flexibility, wide in application range, small in heat loss and convenient to install and wash, realizes high-efficiency heat exchange and also realizes the aim of saving energy.

Description

technical field [0001] The invention belongs to the field of refrigeration and air-conditioning equipment, in particular to an evaporative cooling / air-cooling heat exchange composite condenser. It is suitable for fields that require year-round cooling such as data center computer rooms. Background technique [0002] In recent years, with the rapid development of all walks of life, the fields that need year-round cooling are increasing, and their energy consumption is also increasing. Taking the field of data centers as an example, my country's data center (IDC) market is developing rapidly, and the energy consumption of data centers in 2014 has exceeded 83 billion kWh. Since a large number of servers, storage and network equipment are gathered in the computer room of the data center, the heat generated is huge, and the heat needs to be discharged outside almost all year round, so that the air conditioner accounts for a large proportion of the total energy consumption of the...

Problems solved by technology

[0004] The present invention proposes an evaporative cooling / air-cooling heat exchange composite condenser, which is especially suitable for fields such as data center machine rooms that require year-round cooling, and solves the problem of direct cooling of the condenser due to spray water in the current technology. Spraying on the heat exchange tube wall will cause scaling and corrosion on the surface of the heat exchange tube, affecting the heat exchange efficiency and freezing of circulating water when the outdoor temperature is too low
