Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange equipment, in particular to a heat exchange structure. Background Art

[0002] The heat exchange structure is an indispensable part of the refrigeration system. Its main function in the whole refrigeration cycle is to transfer the heat of the refrigerant. The existing Chinese patent publication number is: CN218410846U. The name of the patent is "Aluminum fin copper tube for condenser radiator". The patent includes "a mounting frame, which is configured with a plurality of mounting holes; a copper tube installed in the mounting hole, and the copper tube is linearly configured with a plurality of annular protrusions along the axis direction of the copper tube, and there is a distance difference between the outer surface of the annular protrusion and the outer surface of the copper tube, so that an annular groove is configured between adjacent annular protrusions and the copper tube."

[0003] However, the disadvantage of the existing technical solution is that when the overall ambient temperature is high or the air flow range is limited, the heat exchange effect of the above method is greatly weakened, which is not conducive to normal heat dissipation. Therefore, we propose a heat exchange structure. Utility Model Content

[0026] Please refer to 1-3. The utility model provides a heat exchange structure, including a sleeve 1, a plurality of parallel-distributed capillaries 2 are passed through the sleeve 1, a flow channel space 3 is formed between the capillaries 2 and the sleeve 1, a dividing strip 4 spirally wound on the parallel-distributed capillaries 2 is provided in the flow channel space 3, a plugging tube 6 is sleeved at both ends of the sleeve 1, a shunt tube 7 is connected to the side of the body of the plugging tube 6, a connecting tube 8 is fixedly passed through the bottom of the plugging tube 6, and each capillaries 2 is connected to the connecting tube 8;

[0027] Working principle: the sleeve is arranged on the outside of multiple parallel distributed capillaries to form a flow channel space for the coolant to flow, thereby realizing heat exchange with the refrigerant in each capillaries, and then the coolant in the flow channel space flows out through the diverter pipe, thereby realizing liquid cooling of the capillaries. The parallel capillaries also increase the contact area during heat exchange between the refrigerant and the coolant in the flow channel space, which is beneficial to improving the cooling efficiency and reducing the impact of the overall high ambient temperature or air flow, and has good practical significance.

[0028] As another embodiment provided by the present invention, the strip body of the dividing strip 4 is a corrugated strip, and a plurality of tooth grooves 4.1 are opened on one side of the strip body of the dividing strip 4 away from the inner wall of the sleeve 1, and a guide plate 4.2 is provided in the groove of the tooth groove 4.1. In actual use, during the flow of the coolant in the flow channel space 3, a part of the coolant close to the inner wall of the sleeve 1 flows toward the capillary 2 under the guidance of the guide plate 4.2, which increases the degree of disturbance of the coolant flow, and is conducive to more complete heat exchange contact between the coolant and the capillary 2. At the same time, the wavy dividing strip 4 spirally wound on the parallel distributed capillary 2 increases the flow distance of the coolant, thereby increasing the heat exchange time between the coolant and the capillary 2, thereby improving the effect of the entire heat exchange process as a whole.

[0029] Furthermore, the tube mouth end of the blocking tube 6 can be adapted and inserted in the sleeve 1, and a sealing gasket sleeve 5 is fixedly sleeved on the outer side of the tube mouth end of the blocking tube 6, the end of the dividing strip 4 is in contact with the inner bottom surface of the blocking tube 6, the tube body insertion end of the shunt tube 7 can be in contact with the capillary 2, and the end of the shunt tube 7 can be spirally clamped with the spiral line of the dividing strip 4. During actual assembly, a plurality of capillary tubes 2 arranged in parallel and wrapped with the dividing strip 4 are inserted into the sleeve 1. Since the insertion end of the shunt tube 7 is located in the blocking tube 6, the blocking tube 6 is then inserted into the sleeve 1. At this time, the blocking tube 6 is rotated and inserted into the sleeve 1, and the insertion end of the shunt tube 7 moves along the spiral line of the dividing strip 4, thereby realizing the spiral connection between the blocking tube 6 and the shunt tube 7. At the same time, the sealing gasket sleeve 5 plays a role of filling and sealing between the sleeve 1 and the blocking tube 6.

[0030] Among them, the inner wall surface of the tube body of the connecting tube 8 is provided with a plurality of evenly distributed spiral grooves 10 to increase the contact area between the refrigerant and the inner wall of the connecting tube 8, and the end of the insertion end of the shunt tube 7 is provided with a plurality of through holes 9, so as to facilitate the coolant in the flow channel space 3 to enter the shunt tube 7 through the through holes 9. It should be particularly noted that the capillary tube 2 and the sealing tube 6 are fixedly connected by soldering at the gap between the plug-in joints, thereby improving the sealing of the entire heat exchange mechanism.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
