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

A kind of Novel evaporative condenser
Technical field
The present invention relates to a kind of condenser, specifically, relate to a kind of Novel evaporative condenser.
Background technology
Along with more prevalentization of Refrigeration Technique application and the shortage of the energy, people are also more and more higher to the energy-conservation requirement of Refrigeration Technique.In refrigerating plant, condenser kind is a lot, mainly contains air-cooled, water-cooled and evaporative condenser; Air cooled condenser exists operational efficiency low, and systematic running cost is higher, bulky and defects such as compressor shortening in service life that higher compression ratios causes.Water cooled condenser operational efficiency is higher, compact conformation, but needs configuration cooling tower and cooling water recirculation system, and water consumption is large and need increase water treatment expense.Evaporative condenser is a kind of compact heat transmission equipment that has merged air-cooled, water-cooled and cooling tower, mainly relies on the evaporation of moisture to make condensation of refrigerant heat radiation, and operational efficiency is the highest.Evaporative condenser has been got rid of the water treatment problems that in water cooled system, the problem of water pump produces with a large amount of waters; Compare with the air cooled condenser with equal refrigerating capacity and cost, their power of fan is much smaller.The most important thing is, adopt refrigeration, the air-conditioning system of evaporative condenser, its condensing pressure can be than traditional water-cooled or air-cooled lower.Like this, the power that compressor consumes just reduces.
The current main heat exchanger components of evaporating type condensing device mostly is coiled, heat exchange efficiency is poor, Whole Equipment volume also larger weight is also larger, in heat exchange coil, need cooling medium charging amount also many, during quantity of circulating water Datong District the loss of water also large, air mass flow is also large, system power dissipation is large, cannot mechanical cleaning after the easy scale effect heat exchange of heat exchange coil outer surface and fouling, cannot realize the aspects such as miniaturization, more and more can not meet modern client's user demand.
Summary of the invention
Object of the present invention is exactly in order to overcome the above problems, and provide a kind of Novel evaporative condenser, adopt finless full aluminium micro-channel heat exchanger, significantly reduce the weight of heat exchanger, when guaranteeing identical heat exchange amount, can significantly reduce the volume of heat exchanger, significantly reduce the charging amount of refrigeration working medium in heat exchanger simultaneously, simultaneously also can mechanical cleaning.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is as follows:
A Novel evaporative condenser, is comprised of housing, heat exchanger, blower fan, spray water system, water pump, water leg, pipeline and the ball-cock assembly of condenser; It is characterized in that, described heat exchanger is full aluminium micro-channel heat exchanger, comprises discharge, collector tube, the middle flat tube between discharge and collector tube, medium inlet and five parts of media outlet; The lateral width of the middle flat tube of described heat exchanger is wider than frontal width, and is all provided with a spray water system between the side of every adjacent two middle flat tubes; Described spray water system is positioned at the bottom of the discharge of heat exchanger; Described spray water system is respectively to the side water spray of flat tube in the middle of described in both sides, the water that makes spray along the side of middle flat tube from flat tube overhead stream in the middle of described to bottom; Described blower fan is positioned at the air outlet of the housing of described condenser, and described blower fan drives extraneous air to enter the water spray wing passage of the middle flat tube of heat exchanger, and so empty G&W while is carried out heat exchange with the cold-producing medium in the middle flat tube of heat exchanger; Described water leg is positioned at the bottom of described heat exchanger; Described water pump is connected between water leg and spray water system, by the water of water leg inside by Pipeline transport to spray water system.
In the above water leg, be provided with ball-cock assembly; Described ball-cock assembly is controlled the water level in described water leg.
The present invention compared with prior art, has the following advantages: 1, the whole heat exchangers of Novel evaporative condenser of the present invention do not exist lee face, and heat exchange area has obtained fully effectively utilizing, compact equipment, and volume is little; 2, the parallel air stream skimming over can touch the side surface of the middle flat tube of heat exchanger in all directions, almost there is no dead angle, the side surface of the middle flat tube of heat exchanger can be covered with water membrane uniformly, so empty G&W while is carried out heat exchange with the cold-producing medium in the middle flat tube of heat exchanger, evaporative cooling effect has obtained larger improvement, has greatly improved the heat transfer efficiency of heat-transfer pipe; 3, full aluminium is without the design of fin microchannel, and the gap between the flat tube in the middle of heat exchanger is as airflow path, and easy hard hair brush can touch any surface of heat exchanger easily, safeguards, clean maintenance is more convenient, with low cost; 4, Novel evaporative condenser of the present invention, by the combination of full aluminium micro-channel heat exchanger and spray system, the in the situation that of equal working condition and heat transfer effect, only require 50% front face area of the air cooled condenser that is approximately same size, the working medium charging amount of heat exchanger domestic demand condensation cooling reduces more than 45%, and the overall weight of equipment reduces 30%; Can reduce the systemic circulation water yield and air mass flow, thereby reduce the power of water pump and blower fan, realize lower energy consumption simultaneously.
