Description
Technical field
The present invention relates to a kind of liquid separating air condenser, belong to the Thermal Equipment technical field.
Background technology
Aerial condenser is a class Thermal Equipment, uses very extensively in power, chemical industry, Air-conditioning Engineering and Refrigeration Engineering, as refrigerator, and refrigerator, automobile is in the thermal power plant.
Figure 1 shows that traditional Air Conditioning condenser.As Fig. 1, figure (a) is a conventional air condenser front view; Figure (b) is a conventional air condenser vertical view; Figure (c) is a conventional air condenser side view.Wherein, 100-shell, 200-air intake, 300-three-way pipe, 400-condensate outlet.The conventional air condenser adopts coiler-type more, relies on the heat convection of air outside pipe, and refrigerant vapour is at in-tube condensation.The condenser pipe inlet of this Air-cooled Condenser is pure steam, is neat liquid substantially through full pipe range condensation outlet, realizes whole condensations.In the pipe in the condensation heat transfer, along with the wall condensation water that carries out of condensation progressively increases, film forming has hindered contacting of steam and wall subsequently, is the main thermal resistance place of condensation heat transfer.Liquid film progressive additive in the condensation process, the complicated two phase flow that progressively increases for liquid in the quite long afterwards tube side, thermal resistance increases gradually, the serious variation of condensation effect; While, quantity of steam reduced gradually along with steam condenses, and steam flow rate obviously descends in the pipe, and condensation effect decreases sharply, and the coefficient of heat transfer reduces; The flow process condensation process has also caused complicated biphase gas and liquid flow in the single pipe, to the regulation and control of system's operation stability, flow resistance and system etc., very adverse influence is arranged all.Air side, because in-tube condensation heat exchange thermal resistance increases, the outer tube wall temperature descends, and causes the utilization rate of fin to descend.For solving the problem of above-mentioned existence, conventional air cooled condenser to be strengthening the demand that heat exchange area satisfies the heat exchange amount, and volume, weight are bigger, and making and operating cost height.
Summary of the invention
Goal of the invention: the invention provides a kind of novel liquid separating air condenser, this liquid separating air condenser is a kind of high-efficiency condensation ability that has, high heat transfer coefficient, the novel air cooled condenser of little heat exchanger volume and metal consumption.
