[0035] Embodiment
[0036] As Figure 1-7 shown, a longitudinally arranged condenser includes a condenser core body 1 and a liquid storage and dryer 2. The liquid storage and dryer 2 is welded to one end of the condenser core body 1, and the liquid storage and dryer 2 is conductively connected to the condenser core body 1. The condenser core body 1 is provided with a refrigerant inlet 110 and a refrigerant outlet 130. An inlet joint 15 is provided on the refrigerant inlet 110. The condensation cavity 12 circulates the superheated refrigerant compressed from the compressor to the liquid storage and dryer 2. The condenser core body 1 further includes a first through portion 11, a condensation cavity 12, and a second through portion 13. The first through portion 11 circulates the superheated refrigerant compressed from the compressor to the second through portion 13 through the condensation cavity 12. The condensation cavity 12 includes a housing 120, heat dissipation fins 121, and refrigerant pipes 122. The heat dissipation fins 121 and the refrigerant pipes 122 are installed inside the housing 120. The refrigerant pipes 122 are inserted inside the heat dissipation fins 121. One end of the refrigerant pipe 122 is connected to the first through portion 11, and the other end of the refrigerant pipe 122 is connected to the second through portion 13. During specific use, the superheated refrigerant compressed from the compressor enters the condenser core body 1 from the inlet joint 15. The superheated refrigerant flows towards the liquid storage and dryer 2 through the curved refrigerant pipes 122. During the circulating flow, the heat in the superheated refrigerant is absorbed by the heat dissipation fins 121, and the temperature of the superheated refrigerant is cooled through heat exchange with the heat dissipation fins 121. The cooled refrigerant is introduced into the liquid storage and dryer 2 through the second through portion 13 and enters the expansion tank for use. Through reciprocating flow, it effectively ensures the normal operation of the system and the problem of system oil return.
[0037] The liquid storage and drying tank 2 includes a tank body 21, a fitting plate 22, and a support shaft 23. The fitting plate 22 is installed at the upper end of the tank body 21, and corresponding liquid inlet ports 210 are provided on the tank body 21 and the fitting plate 22. The liquid inlet port 210 is connected to the second connecting portion 13. The support shaft 23 is fixed to the lower end of the tank body 21. A liquid outlet port 211 is provided at the lower end of the tank body 21. The fitting plate 22 can stably connect the tank body 21 and the second connecting portion 13. At the same time, reducing the contact area between the tank body 21 and the second connecting portion 13 can effectively reduce the heat transfer of the housing 120 to the tank body 21 through solid conduction by the second connecting portion 13, improving the cooling efficiency.
[0038] A liquid outlet joint 24 is connected to the liquid outlet port 211. The upper part of the liquid outlet joint 24 is arc-shaped. The upper part of the liquid outlet joint 24 is connected to the lower end of the tank body 21 by brazing. A bolt hole 240 is provided on one side of the liquid outlet joint 24. The installation angle of the liquid outlet joint 24 can be freely adjusted according to actual needs with the condenser core 1. In this embodiment, it is vertical, enabling the longitudinal condenser to save the overall machine layout space. At the same time, it saves a transfer pipeline and a liquid storage and drying tank mounting bracket. By reducing one transfer pipeline, its flow resistance is reduced.
[0039] An arc-shaped protrusion 220 is provided on the fitting plate 22. The liquid inlet port 210 is provided at the center of the arc-shaped protrusion 220. The fitting plate 22 is fitted and connected to the lower end of the second connecting portion 13 through the arc-shaped protrusion 220. Through the arc-shaped protrusion 220, the fitting plate 22 can be better connected to the second connecting portion 13, expanding the sealing area of the liquid inlet port 210 and avoiding leakage problems caused by attenuation of the connection strength during use.
[0040] Connecting plates 14 are provided on the sides of the first connecting portion 11 and the second connecting portion 13. A groove 140 is provided in the middle of the connecting plate 14. Connecting pieces 141 are provided on the outside of the connecting plate 14. Mounting pieces 111 are provided at the top of the first connecting portion 11. Mounting holes 112 are provided at the top of the mounting pieces 111. The device can be better fixed through the mounting pieces 111 and the connecting plates 14.
[0041] Guard plates 123 are provided on the left and right sides of the housing 120. The two sides of the guard plates 123 protrude and the middle is concave.
[0042] The refrigerant pipe 122 is connected by arranging multiple pipe bodies in a circle, and the distance between two pipe bodies is the same. The refrigerant pipe 122 is a metal pipe. A number of small grooves are provided on the refrigerant pipe 122. There is a series of metal pipes arranged in a circle inside the housing 120, and there are many small grooves on the surface of the metal pipes. When the refrigerant passes through these grooves, it cools the temperature of the coolant through heat exchange with the surface of the metal pipe. The refrigerant re-enters the cycle after passing through the condenser, completing the cycle cooling process.
[0043] The heat dissipation fin 121 is composed of several groups of fins with the same size arranged. A cavity is formed between two adjacent fins. The cavity is triangular or rectangular. The heat dissipation fin 121 includes, but is not limited to, aluminum and copper. After the heat dissipation fin 121 absorbs the heat from the refrigerant pipe 122, it dissipates the heat in the form of convection. In the process of convective heat dissipation, the heat dissipation area is mainly determined by the size of the surface area of the heat dissipation fin. The larger the surface area, the better the heat dissipation effect; the smaller the surface area, the worse the heat dissipation effect. The main means adopted include: increasing the number of heat dissipation fins and increasing the length of the heat dissipation fins. One of the data reflected is the "thickness-to-height ratio" - that is, the ratio of the thickness to the height of the fins of the heat sink. The smaller this value is, the denser the heat dissipation fins per unit volume can be made, the more the number, the larger the effective heat dissipation surface area, and the better the heat dissipation performance.
[0044] As Figure 8 shown, according to the actual usage situation, adjust the installation position of the liquid inlet joint 15, and set the condenser core 1 to a two-pass process. The specific flow mode of the refrigerant is as shown by the arrow.
[0045] The above are only the embodiments of the present utility model. Specific structures and common knowledge such as characteristics well known in the art are not described in detail herein. Those of ordinary skill in the art know all the common technical knowledge in the technical field to which the utility model belongs before the application date or the priority date, can know all the prior art in this field, and have the ability to apply the conventional experimental means before this date. Those of ordinary skill in the art can, under the inspiration given in this application, combine their own abilities to improve and implement this solution. Some typical well-known structures or well-known methods should not become an obstacle for those of ordinary skill in the art to implement this application. It should be pointed out that for those skilled in the art, without departing from the structure of the present utility model, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent.
