Description

TECHNICAL FIELD

[0001] The application relates to a copper-fluorine cold and hot radiation system technical field, in particular to a refrigerant distributor for a copper-fluorine cold and hot radiation system and an assembling method thereof. BACKGROUND

[0002] The refrigerant distributor for the copper-fluorine cold and hot radiation system is a core distribution device integrated in the copper-fluorine cold and hot radiation system, and high-efficiency refrigerant distribution and heat exchange are realized through structural design.

[0003] The traditional refrigerant distributor often faces three technical bottlenecks of low heat exchange efficiency, poor distribution uniformity and insufficient sealing reliability in the heat radiation system. The linear flow channel design leads to short refrigerant flow path and weak turbulence, and the heat exchange efficiency per unit pipe length is insufficient, so that the system needs to increase the pipe size or increase the refrigerant flow to compensate, directly increasing the energy consumption and cost. The fixed distribution head cannot be dynamically adjusted according to the refrigerant flow, which easily causes excessive or insufficient refrigerant in local areas, causing significant uneven heat radiation and local supercooling / overheating problems, seriously affecting the stability and use comfort of the system. The single-layer sealing structure is easily affected by factors such as the difference in thermal expansion coefficient, mechanical vibration or long-term use aging, and is prone to refrigerant leakage. At the same time, the lack of buffer design of the rotating assembly leads to increased mechanical wear and tear and vibration noise, greatly reducing the service life and reliability of the system, and restricting the efficient and stable operation of the system and the improvement of energy-saving and comfortable performance.

Assemble the sealing structure: Insert the female connector (132) of the sealing joint (13) into the first sealing sub-connector (113) of the direct pipe (11) and the second sealing sub-connector (123) of the elbow pipe (12) respectively to form a double sealing barrier; S4. Install and allocate components (3): S4-1. Assemble the rotating assembly (31): Install a second rotating bearing (314) on the outer periphery of the rotating disk (313), fix the inner groove rotating disk (311) and set the first rotating bearing (312), fix the rotating blade (316) through the straight shaft (315) to ensure that the rotating blade (316) can rotate with the flow of refrigerant; S4-2. Install the top head (32): Slide the circular top block (321) into the sliding groove (3174) of the inserting circular block (317), and connect the damped springs (322) evenly around the circumference to form a buffer structure; S4-3. Connecting the distribution connector (33): Insert the fixing block (332) of the inner circular groove frame (331) into the fixing groove (3172) of the plug-in circular block (317), and fix the distribution impeller (334) through the long shaft (333). S5. Overall assembly: Rotate the assembled distribution component (3) into the rotating slot (115) to ensure that the distribution impeller (334) can rotate with the rotating component (31) to achieve uniform distribution of refrigerant; finally, fix the top plate (2) array at equal intervals to the top of the distribution pipe (1) to complete the assembly.

10. The assembly method of a refrigerant distributor for a copper-fluorine radiant heating and cooling system according to claim 9, characterized in that, In step S3, the sealing joint (13) adopts a double female joint (132) symmetrical plug-in structure, which, together with the first sealing sub-joint (113) and the second sealing sub-joint (123), forms a triple sealing interface, effectively preventing refrigerant leakage due to differences in thermal expansion coefficients or mechanical vibration; the spring (322) damper is set between the circular top block (321) and the inner wall of the sliding groove (3174), and the spring compression and damping energy dissipation realize the buffering and shock absorption of the rotating component (31), improve rotational stability and extend service life; In step S4-3, the blade angle of the distribution impeller (334) is dynamically adjustable according to the refrigerant flow rate. The distribution ratio is controlled by the rotation angle feedback of the rotating component (31) to achieve precise dynamic distribution of refrigerant in the heat radiation area. The inner wall of the rotating groove (115) is provided with a wear-resistant coating, which, together with the spring buffer structure of the top head (32), reduces the mechanical wear between the rotating component (31) and the groove wall.
