Description

Technical Field

[0001] This invention relates to the field of heat exchanger technology, specifically a finned structure for a heat exchanger. Background Technology

[0002] A heat exchanger is a device that transfers some of the heat from a hot fluid to a cold fluid. It can perform heat exchange on media at different temperatures to achieve the operating temperature of different media. Finned radiators are the most widely used heat exchange equipment in gas-liquid heat exchangers. They enhance heat transfer by adding fins to ordinary base tubes and are widely used in power, chemical, petrochemical, air conditioning and refrigeration engineering.

[0003] The finned structure of existing heat exchangers is usually fixed on the base tube. The specifications of the base tube and fins cannot be adjusted, and they cannot be adjusted according to the different flow velocities of the hot fluid. The hot fluid with a faster flow rate cannot fully exchange heat with the fins, which affects the heat exchanger's heat exchange effect. The hot fluid with a slower flow rate flows slowly in the base tube, which affects the efficiency of the heat exchanger and is not conducive to the normal use of the finned heat exchanger. Summary of the Invention

[0004] The purpose of this invention is to provide a finned structure for a heat exchanger to solve the problem of inconvenience in using existing finned structures for heat exchangers.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A finned structure for a heat exchanger, including a heat exchange chamber, and further comprising: The heat exchange box has a movable plate that slides on top. An inlet pipe and an outlet pipe are mounted on the movable plate. Heat exchange tubes are installed inside the heat exchange box. Multiple finned bodies are sleeved around the heat exchange tubes. An mounting plate is installed at the bottom of each finned body. A sealing plate slides inside the heat exchange box. Clamping plates are installed on both sides of the movable plate. One end of each clamping plate passes through the heat exchange box and connects to the sealing plate. An elastic element is installed between the sealing plate and the inner wall of the heat exchange box. Multiple connecting rods are mounted on the elastic element. Mounting grooves that mate with the connecting rods are provided on the mounting plate. The heat exchange tube is provided with multiple connecting pipes, each with a through hole. Both ends of the connecting pipe are provided with connecting pipes that connect to the heat exchange tube. A sealing ball and a sealing block are provided inside the connecting pipe. A sleeve is provided on the side of the sealing block near the sealing ball. A return spring is fitted on the outside of the sleeve. One end of the return spring is connected to the sealing ball. A transmission groove is provided on the other side of the sealing block.

The movable plate, in cooperation with the sealing plate, drives the elastic element to extend and retract. The elastic element controls the unfolding of the fin body by driving the mounting plate to move left and right. The inlet pipe passes into the connecting pipe and presses down on the sealing block. The hot fluid flows into the heat exchange tube. The heat exchange tube exchanges heat with the hot fluid by cooperating with the fin body.

[0026] like Figure 1-4 As shown, in a preferred embodiment of the present invention, a guide groove 103 is provided at the bottom of the inner cavity of the heat exchange box 1, and a slider 16 is slidably arranged inside the guide groove 103. The rotating shaft 25 is fixedly arranged on the slider 16, and the slider 16 moves left and right along the guide groove 103.

[0027] like Figure 1-7 As shown, in a preferred embodiment of the present invention, the heat exchange box 1 has a square groove 101 and a sliding groove 102 on its top. The liquid inlet pipe 7 and the liquid outlet pipe 6 both pass through the square groove 101 into the heat exchange box 1. A pull plate 17 is fixedly arranged between the liquid inlet pipe 7 and the liquid outlet pipe 6. A pull rod 9 is arranged at the center of the pull plate 17.

[0029] like Figure 2 As shown, in a preferred embodiment of the present invention, the movable plate 5 has a cavity 501 inside, and a telescopic spring 10 is provided inside the cavity 501. The top end of the telescopic spring 10 is connected to the pull rod 9. The telescopic spring 10 can drive the pull rod 9 to return downward, so that the liquid inlet pipe 7 and the liquid outlet pipe 6 pass downward into the through hole 121.

[0030] like Figure 6As shown, in a preferred embodiment of the present invention, slots 104 are provided on both sides of the heat exchange box 1.

The fin bodies 4 can move left and right along the heat exchange tube 11, facilitating the adjustment of the spacing between the fin bodies 4. The hot fluid to be exchanged enters the heat exchange chamber 1 through the inlet pipe 7. After heat exchange is completed, it is discharged through the outlet pipe 6. When the flow rate of the hot fluid is high or the temperature is high, the handle 8 drives the movable plate 5 to move to the left. The movable plate 5 drives the inlet pipe 7 and the outlet pipe 6 to move to the left and connects them to the connecting pipe 12 at the left end of the heat exchange tube 11, thus lengthening the path of the hot fluid through the heat exchange tube 11. The sealing plate 18 The support frame 2 moves to the left, the elastic element 3 expands outward and drives the fin body 4 to move through the connecting rod 27. Multiple fin bodies 4 move along the heat exchange tube 11 and expand outward, increasing the spacing between the fin bodies 4 and the contact area between the fin bodies 4 and the air or heat exchange medium, thus increasing the heat exchange efficiency of the heat exchanger. When the flow rate of the hot fluid is slow, the handle 8 drives the movable plate 5 to move to the right, connecting the inlet pipe 7 and the outlet pipe 6 to the connecting pipe 12 at the right end of the heat exchange tube 11, reducing the distance the hot fluid flows out of the heat exchange tube 11 and accelerating the heat exchange speed of the heat exchanger. The heat exchange tube 11 and the fin body 4 can be adjusted according to specific usage requirements.
