Novel evaporative condenser

Abstract

The invention discloses a novel evaporative condenser. The novel evaporative condenser is composed of a shell of the condenser, a heat exchanger, a fan, water spraying devices, a water pump, a sump tank, a pipeline and a ball cock. The heat exchanger is a total-aluminum microchannel heat exchanger. One water spraying device is arranged between the side faces of every two adjacent middle flat pipes of the heat exchanger. The water pump is connected between the sump tank and the water spraying devices to convey cooling water inside the sump tank to the water spraying devices through the pipeline. The water spraying devices spray water to the side faces of the middle flat pipes on the two sides respectively, and sprayed water flows to the bottoms of the middle flat pipes from the tops of the middle flat pipes along the side faces of the middle flat pipes. The fan drives external air to enter channels on the water spraying side of the middle flat pipes of the heat exchanger, and therefore air and water can conduct heat exchange with refrigerant in the middle flat pipes of the heat exchanger at the same time. The novel evaporative condenser has the advantages of being high in heat transfer efficiency, low in cost, small in wind resistance on the windward side, easy to manufacture and convenient to clean.

Description

technical field [0001] The invention relates to a condenser, in particular to a novel evaporative condenser. Background technique [0002] With the increasingly popular application of refrigeration technology and the shortage of energy, people's requirements for energy saving of refrigeration technology are also getting higher and higher. In refrigeration devices, there are many types of condensers, mainly including air-cooled, water-cooled and evaporative condensers; air-cooled condensers have low operating efficiency, high system operating costs, large volume and high compression ratio. Defects such as shortened service life of the machine. The water-cooled condenser has high operating efficiency and compact structure, but it needs to be equipped with a cooling water tower and a cooling water circulation system, which consumes a lot of water and increases the cost of water treatment. The evaporative condenser is a compact heat exchange equipment that combines air-cooled,...

Problems solved by technology

[0003] The main heat exchange components of the current evaporative condensing device are mostly coil type, the heat exchange efficiency is relatively poor, the overall volume of the equipment is also relatively large and the weight is relatively large, the charge of the condensing medium in the heat exchange coil is also relatively large, and the amount of circulating water At the same time, the loss of water is also large, the air flow rate is also large, the power consumption of the system is large, the outer surface of the heat exchange coil is easy to scale, which affects the heat exchange, and after scaling, it cannot be cleaned mechanically, and it cannot be miniaturized. It is increasingly unsatisfactory. The needs of modern customers
