Field of the Invention The present invention relates to a heat exchange device for use in a refrigerant evaporation device used in a mechanical refrigeration device, and more particularly to a shower type heat exchange split. [Prior Art] The mechanical refrigeration equipment includes four main components: a compressor, an expansion device, a condensing device, and an evaporation device, and the evaporation device can be roughly classified into a direct expansion type, a full overflow type, and a shower type. The overflow and direct expansion main structures are all ones of the inner tube type heat exchangers. The direct expansion type flows the refrigerant inside the tube, and the target fluid flows on the shell side to prevent the liquid refrigerant in the tube from being steamed. The compressor is not completely sucked into the compressor and the compressor is damaged. Therefore, in the direct expansion system, it is necessary to increase the superheat of the inlet end of the compressor, resulting in the power consumption of the compressor. The inside of the overflow-type refrigeration equipment tube is the target fluid refrigerant, and the refrigerant flowing on the shell side is not easy to absorb the liquid refrigerant at the inlet end of the compressor, so the superheat of the refrigerant at the inlet end of the compressor can be reduced, and the compression can be reduced. The power consumption of the machine. However, since the overflow evaporating device is for immersing the tube in the liquid refrigerant in the shell, a larger amount of liquid refrigerant is needed to soak the tubes in the shell, resulting in more than twice as much refrigerant filling as the direct expansion type. Quantity increases equipment costs and environmental burden. The shower evaporator uses the chilled refrigerant to form a liquid thin layer on the inner tube of the shell. The gravity or other force influences the vertical or parallel direction of the tube to move, and the refrigerant will be laid by the refrigerant outside the tube. Target fluid = take away, the purpose of the Dalai exchange. Because the liquid damper adds 'in the surface of the secret tube' to accelerate the evaporation of the liquid cold _ body on the surface of the heat transfer tube into a gaseous refrigerant value, you can increase the efficiency of the heat exchange device, reduce the heat in the shell, and cost at least 25%. 'At the same time, because it is not necessary to immerse the heat pipe in a large amount of liquid 1291541, it can also reduce the refrigerant filling capacity of the mechanical refrigeration equipment by more than 2%. However, many mechanisms, such as the use of a shower-type evaporation device, can affect the performance of the shower-type hair-sending device. If the mechanism for showering the refrigerant is not effectively controlled, the poor distribution of the refrigerant on the heat-transfer tube will result in Energy consumption of refrigeration equipment 0 SUMMARY OF THE INVENTION The main object of the present invention is to provide a shower type heat exchange device, which can uniformly control the distribution of the wire cooling system, effectively improve the cooling efficiency, and plough the material according to the invention. The heat exchange device comprises: a heat transfer pipe and a distributed refrigerant shower die, a group, the body has an opening for accommodating space and a accommodating space, and the heat transfer pipe is disposed in the accommodating space of the body, and is divided into The sprinkling module comprises an axial distribution f, a liquid refrigerant σ and a refrigerant immersed in the axial distribution of the tube Wei Wei_ hole, and a miscellaneous refrigerant medium setting _ 死, the liquid refrigerant can be input to the axial distribution tube through the liquid refrigerant inlet The second grievance refrigerant passes through the m to the refrigerant level to the scale tube, and then turns into a gaseous refrigerant, and flows out through the opening of the body; # this will liquid the liquid on the field, improve the refrigeration , :: material cost can be reduced. _Early and related to the details and technology of this creation, please refer to the following description. [Embodiment] Bu · According to the shower type heat exchange device disclosed in the present invention, please refer to "^ contains the body 10, distributed refrigerant The shower module 20 and the heat transfer tube 3 are substantially in the shape of a container, and have an inner receiving portion and an opening 12. The heat transfer tube 30 can be in the form of staggered or coiled. 1291441 The position of the bottom portion of the accommodating space 11 of the main body 10. The distributed refrigerant shower module 20 includes an axial distribution tube 21 having a liquid refrigerant inlet 22 and a plurality of openings 2U on the bottom surface, see /' Fig. 2 is a bottom view of the refrigerant shower surface 23, and has a plurality of shower openings 231 for liquid refrigerant showering (see Figure 3). Further, the axial distribution pipe 21 can be connected to the refrigerant shower surface 23 by means of the baffle 24, and by this means, the baffle 24 can provide the function of flying money. 7 ' The liquid refrigerant is introduced into the axial distribution tube 21 from the liquid refrigerant inlet 22 of the distributed refrigerant shower module 20, because it is a long axial extension, so that the liquid refrigerant can be evenly distributed in the long axial direction. Then, through the opening 211 of the bottom surface of the axial distribution pipe 21, it can be dripped to the cooling shower surface 23. At this time, the sandstone can prevent the liquid stagnation refrigerant from dropping, and on the other hand, it can be added. There is a buffer material 232 (see Figure 3), such as chemical fiber non-woven fabric, vegetable fiber non-woven fabric, sponge or sponge similar material, mesh woven fabric, metal velvet and non-metallic velvet. In addition, it can absorb the f impact force generated by the direct impact of the liquid refrigerant to reduce the splash of the liquid refrigerant and prevent the liquid refrigerant from rapidly leaching from the refrigerant. The shower opening 231 of the surface 23 is sprayed onto the heat transfer pipe 30, causing the liquid refrigerant to drain. ,uniform. The shower opening 231 of the refrigerant spray surface 23 can be any geometric hole, groove or grid type in addition to the circular hole shown in the drawing, and the liquid refrigerant can be promoted here. Uniform distribution of two-dimensional planes. The liquid refrigerant that is dripped forms a liquid film on the heat transfer pipe 30, and is moved vertically or in parallel with the heat transfer pipe 3〇 by gravity or other extensive influence. Similarly, the liquid refrigerant evaporates and heats the heat pipe 3 The heat of the target fluid is carried away to achieve the purpose of heat exchange. Since the flow rate of the liquid refrigerant on the surface of the heat transfer tube 3 increases, the rate at which the liquid refrigerant fluid evaporates into the gaseous refrigerant on the surface of the heat transfer tube 3 is accelerated, so that the efficiency of the heat exchange device can be increased, and the cost can be reduced by at least 25%. Since it is not necessary to immerse the heat transfer tube 3 in a large amount in the liquid refrigerant, the refrigerant charge amount of the mechanical refrigeration equipment can be reduced by 2% or more. 1291541 Port 12 After the father exchanges the vaporized refrigerant, the money 11 is opened by the body 10 and can be opened. ^Into the step - prevent liquid refrigerant_compressor, continue to sweat and set the liquid separation device to prevent splashing The liquid particles return to the pressure, the % machine, and the collisions have their shop-type device. And the effect of the Weibu Jidong, of course, can also increase the amount of liquid refrigerant, machine bamboo ^", and Guanguan 3G soaked in liquid refrigerant towel. This can effectively improve the cold design _ efficiency 'saving energy inspection f and saving equipment The manufacturing cost can make the efficiency of mechanical refrigeration equipment higher than that of using overflow evaporator
