The high pressure refrigerant that heat exchanger 10 reception compressors 40 push is to carry out the work of cooling medium liquefaction, cooperate and utilize water supply system 20 supply feedwater to quicken to promote its liquefaction usefulness, and mat fan 34 motors 32 drive fan 34 air-flow between the air aisle of heat exchanger 10, on the one hand carry out heat exchange and take away the refrigerant heat, on the other hand the steam band that will evaporate through heat exchange from.
As shown in Figure 3, for the heat exchanger 10 of main body of the present invention is the fin type structure, 110 pipes that rise of radiating fin that penetrate vertical arrangement by refrigerant pipe 122 connect airtight and constitute.Form two extra first and second radiating areas 230,240 beyond the upper/lower terminal that radiating fin is 110 groups stretches out in refrigerant coil pipe 120 districts respectively,, improve cooling effect to increase area of dissipation.As shown in Figure 4, wherein, refrigerant pipe 122 modes of main system through laterally being connected in series form each layer refrigerant coil pipe 120.The import system of each layer refrigerant coil pipe 120 is connected with the refrigerant ingress pipe 124 that is connected compressor 40 with the bottom with parallel way, the high pressure-temperature refrigerant that compressor 40 promotes by under push this ingress pipe 124 and each layer refrigerant coil pipe 120 that arrives, also be exactly, refrigerant coil pipe 120 is to replace traditional single design on earth with parallel way, make refrigerant condensation simultaneously in all refrigerant pipes 122 of each layer refrigerant coil pipe 120, increase the condensation number of unit interval, that is the increase condensation rate, and don't need to improve pressure.This kind promptly saved the energy with the condensation number that improves in the unit interval to improve condensation rate.
As shown in Figure 4, refrigerant coil pipe 120 of the present invention is to be example with three row's radiating fins 110, (hole, row number can adjust) according to virtual condition, because of the row's of being confined to number less, for having made suitable and sufficient length is carried out cooling medium liquefaction.Be earlier the horizontal again and adjacent refrigerant pipe 122 of arranging after two refrigerant pipes 122 connect up and down to be connected among the present invention, so finish each layer refrigerant coil pipe 120 through three windings.This winding gimmick can be with different variation of heat exchanger hole row's number.For example, when row's number increases, adopt directly horizontal each row of serial connection to form with layer refrigerant pipe when changing, it mainly is to determine according to each refrigerant coil pipe Len req.
As shown in Figure 2, water supply system 20 is that collocation is for further improving the condensation efficiency of heat exchanger.
As shown in Figure 5, water supply system 20 comprises the case 210 that drips, water storage box 220 and is positioned at first and second radiating areas 230,240 of 110 upper and lower sections of radiating fins.Case 210 splashes into cooling water in the fin type heat exchanger 10 by dripping.Water storage box 210 mainly is used as the source of cooling water with residue cooling water behind fin type heat exchanger 10 and assistant to introduce outside water supply with the water yield of supplement consumed.Remaining cooling water system mat second radiating area 240 cooling in advance of heat exchange, and the cooling water that is directed into the case 210 that drips comes precooling with first radiating area 230 earlier again, the phenomenon of the such design of mat to solve and to prevent to accumulate intensification through the cooling water of reciprocation cycle utilization because of the heat that absorbs refrigerant guaranteed the stability of cooling heat dissipation effect.
The case 210 that drips is to be positioned at fin type heat exchanger 10 upper ends, and cooling water is from top to bottom flowed into.Mat fan 34 motors 32 drive fans 34 in the condensation process, injecting extraneous air to fin type heat exchanger 10 internal air passageway gaps, the mat air will carry out heat exchange and the fast speed belt of moisture evaporated from.The refrigerant that compressor 40 of the present invention pushes enters the ingress pipe 124 of each layer refrigerant coil pipe 120 from lower to upper.According to Bath card principle, under pure zerofriction force situation, each layer refrigerant coil pipe 120 import refrigerant pressure P 1=P2=...=Pn, but because there is frictional force in tube wall, the historical facts or anecdotes border be P1＞P2＞...＞Pn though difference is not too large, must haggle over every penny under the consideration of saving the energy.Add the cooling water that cooperates the case 210 that drips and be drip from top to bottom, last row's cooling water temperature must be a little less than row's cooling water down, because the required critical pressure of the lower liquefaction of temperature is lower, height is also omited in the slightly high then required critical pressure of temperature.To cooperate cooling water just be the cooling effect that drips from top to bottom so this kind refrigerant enters distributor pipe design from bottom to top, make refrigerant coil pipe 120 refrigerants of every group of parallel connection be able to same condensation effect, that is condensation in no particular order the time, thereby need not improve pressure.
As shown in Figure 6, case 210 1 ends that drip are connected with the water pipe 234 of introducing the water source; Case 210 bottom surfaces of dripping wear several osculums 212, wherein be provided with interlayer 214 with water hole 216, and stagger mutually in the water hole 216 and the water hole, bottom surface 212 of interlayer 214, the water hole 212 that interlaces layer by layer by this, 216 design, reducing pressure and the impulsive force of introducing water slowly splashes into to radiating fin 110 and refrigerant pipe 122 again, when making water be conducted to radiating fin 110 tops fully following of the low coverage of no pressure or low-pressure state, thereby just can go downstream when making water on radiating fin 110, only have gravity to surpass skin-friction force, the time that moisturizes and stay at radiating fin 110, make it time enough and under wind-force is blown over, made sufficient constant-temperature evaporation, thereby more can effectively absorb the heat of radiating fin 110 and refrigerant pipe 122.Certainly, also can increase the quantity of interlayer 214 because of actual state, also can stagger mutually in the water hole 216 of each interlayer 214, and pressure and the impulsive force of introducing water are reduced again.
