DETAILED DESCRIPTION

[0035] In order to better understand the above technical solution, the technical solution of the embodiment of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiment of the present application and the specific features in the embodiment are detailed descriptions of the technical solution of the embodiment of the present application, rather than limitations on the technical solution of the present application. In the absence of conflict, the embodiment of the present application and the technical features in the embodiment can be combined with each other.

[0036] The first embodiment of the present application provides a folding heat exchanger 10, such as Figure 1 、 Figure 2 and Figure 3 As shown, the foldable heat exchanger 10 includes: a shell 100, a plurality of baffles 200, a support assembly 300, and heat exchange tubes 400. The shell 100 includes a first barrel 110, a second barrel 120, and an arcuate barrel 130. The ends of the arcuate barrel 130 are connected to the ends of the first barrel 110 and the second barrel 120 respectively. The first barrel 110 and the second barrel 120 extend along a first direction. The first barrel 110 is provided with a liquid outlet 111, and the second barrel 120 is provided with a liquid inlet 121. The plurality of baffles 200 are arranged in the first barrel 110 and the second barrel 120, respectively, and are staggered along the first direction. The support assembly 300 is disposed in the arcuate barrel 130. The heat exchange tubes 400 are disposed in the shell 100 and pass through the support assembly 300 and any baffle 200.

[0037] In this embodiment, Figure 1 The direction indicated by the X arrow is the first direction. The first cylinder 110 and the second cylinder 120 are straight cylinders and extend along the first direction. The first cylinder 110 and the second cylinder 120 are respectively connected to the two ends of the arc cylinder 130, so that the shell 100 forms a U-shaped rotation and folding shape. A liquid outlet 111 and a liquid inlet 121 are respectively provided on the first cylinder 110 and the second cylinder 120. The cold medium enters the shell 100 through the liquid inlet 121, and exchanges heat with the hot medium in the heat exchange tube 400 during the flow process, and is finally discharged from the shell 100 through the liquid outlet 111.

[0038] The heat exchange tube 400 passes through the support assembly 300 and each baffle 200. The baffle 200 provides structural support for the heat exchange tube 400 in the straight section of the cylinder. The support assembly 300 provides tail support for the heat exchange tube 400 in the curved cylinder 130, so that the heat exchange tube 400 is evenly supported and positioned in the shell 100, thereby improving the stability of the heat exchange tube 400 in the shell 100 and avoiding deformation of the heat exchange tube 400.

[0039] A plurality of baffles 200 are provided in the first cylinder 110 and the second cylinder 120. The baffles 200 are arranged perpendicular to the first direction. The baffles 200 guide the cold medium entering the shell 100. Since the baffles 200 are staggered and distributed at intervals along the first direction, after the cold medium enters the first cylinder 110, the flow direction is repeatedly changed by the baffles 200, so that the cold medium forms an S-shaped path in the reciprocating rotation. After the cold medium flows into the second cylinder 120 through the curved cylinder 130, the flow direction is repeatedly changed again by the baffles 200.

[0040] The baffle 200 extends the path length of the cold medium in the shell 100, increases the contact area between the cold medium and the hot medium, prolongs the heat exchange time, increases the total amount of heat exchange, thereby improving the heat exchange efficiency of the heat exchanger and reducing the space occupied by the heat exchanger.

[0041] In some embodiments provided in this application, Figure 6 As shown, optionally, a avoidance plane 210 and a curved surface 220 are provided on the deflector 200, and the curved surface 220 is adapted to the inner wall of the shell 100, and a flow space is formed between the avoidance plane 210 and the shell 100, and adjacent flow spaces are staggered.

[0042] In this embodiment, the avoidance plane 210 and the curved surface 220 of the baffle 200 are connected to form an outer peripheral surface, which is arranged opposite the inner wall of the shell 100. The curved surface 220 is adapted to the inner wall of the shell 100. The curved surface 220 at one end of the baffle 200 is close to the inner wall of the shell 100, while the avoidance plane 210 at the other end forms an arched flow space with the inner wall of the shell 100. The flow space connects the cold medium on both sides of the baffle 200. Because the curved surface 220 end of the baffle 200 blocks the flow of the cold medium, the cold medium flows through the flow space at the flat end to the other side of the baffle 200, controlling the flow direction of the cold medium through the baffle 200. The staggered arrangement of adjacent flow spaces enables the baffle 200 to repeatedly change the flow direction of the cold medium, thereby extending the path length of the cold medium within the shell 100.

[0043] In some embodiments provided in this application, Figure 1 、 Figure 2 and Figure 14As shown, optionally, the folding heat exchanger 10 further includes a plurality of tie rods 500 , which are respectively disposed in the first cylinder 110 and the second cylinder 120 , and the tie rods 500 pass through the baffle 200 and extend along the first direction.

[0044] In this embodiment, when the pull rod 500 extends along the first direction, it passes through multiple baffles 200 in the first cylinder 110 or the second cylinder 120 in sequence, so that the pull rod 500 can radially position the baffle 200, prevent the baffle 200 from rotating radially, and improve the stability of the baffle 200 in the first cylinder 110 and the second cylinder 120.

[0045] Exemplarily, there are multiple tie rods 500 , and the tie rods 500 are evenly distributed on the baffle 200 .

[0046] In some embodiments provided in this application, Figure 14 As shown, optionally, the folding heat exchanger 10 further includes a plurality of distance tubes 600 , which are respectively arranged in the first cylinder 110 and the second cylinder 120 , and the distance tubes 600 are located between two adjacent baffles 200 and are sleeved outside the pull rod 500 .

[0047] In this embodiment, the distance tube 600 is sleeved outside the pull rod 500 and is located between two adjacent baffles 200, so that the distance tube 600 can cooperate with the pull rod 500 to position the baffle 200 axially, avoid axial movement of the baffle 200, and improve the stability of the baffle 200 in the first cylinder 110 and the second cylinder 120.

[0048] In some embodiments provided in this application, Figure 1 、 Figure 4 、 Figure 5 and Figure 7 As shown, optionally, the shell 100 also includes: a tube sheet 150 and a tube box 160, the tube sheet 150 is connected to the end of the first cylinder 110 or the second cylinder 120, one end of the pull rod 500 is connected to the tube sheet 150, the tube box 160 is connected to the tube sheet 150, the heat exchange tube 400 passes through the tube sheet 150 and is connected to the tube box 160, and a vent 163 is provided on the tube box 160.

[0049] In this embodiment, the tube sheet 150 blocks the end of the first barrel 110 or the second barrel 120 to prevent the cold medium from flowing out of the end of the shell 100. The tube box 160 is located at the end of the shell 100, and the tube sheet 150 is located between the tube box 160 and the first barrel 110 or the second barrel 120. The ends of the heat exchange tubes 400 pass through the tube sheet 150 and communicate with the tube box 160. The hot medium in the heat exchange tubes 400 enters or exits the tube box 160 through the vent 163.

[0050] Specifically, there are two tube boxes 160 and two tube sheets 150, one for each. The two tube boxes 160 are a first tube box 161 and a second tube box 162. The first tube box 161 is connected to the first cylinder 110 via the upper tube sheet 150, while the second tube box 162 is connected to the second cylinder 120 via the lower tube sheet 150. The vents 163 are an air inlet 1631 and an air outlet 1632. The first tube box 161 is provided with the air inlet 1631, and the second tube box 162 is provided with the air outlet 1632. The hot medium enters the tube box 160 through the air inlet 1631, flows through the heat exchange tubes 400, and then leaves the tube box 160 through the air outlet 1632. The hot medium and the cold medium flow in opposite directions within the shell 100 to optimize heat exchange.

[0051] For example, one end of the tie rod 500 passes through the tube sheet 150 and is connected to the tube sheet 150, which provides structural support for the tie rod 500. The other end of the tie rod 500 is threaded and connected to a nut to limit the position of the baffle 200 and the distance tube 600.

[0052] In some embodiments provided in this application, Figure 1 、 Figure 2 and Figure 13 As shown, optionally, the support assembly 300 includes a plurality of support plates 310 , which are arranged at intervals along the extension path of the heat exchange tube 400 , and the heat exchange tube 400 passes through any support plate 310 .

[0053] In this embodiment, the heat exchange tube 400 is bent within the arc-shaped cylinder 130. A plurality of support plates 310 are arranged at intervals on the curved path of the heat exchange tube 400, so that the heat exchange tube 400 passes through the plurality of support plates 310 in sequence. The support plates 310 uniformly support and fix the heat exchange tube 400 at the curved position, thereby improving the stability of the curved position of the heat exchange tube 400 and preventing deformation of the heat exchange tube 400.

[0054] For example, the support plate 310 may be formed by splicing a plurality of strip-shaped steel plates.

[0055] In some embodiments provided in this application, Figure 1 and Figure 2 As shown, optionally, the support assembly 300 further includes a support rod 320 , which is connected to any support plate 310 , and a bending radius of the support rod 320 is greater than or equal to a bending radius of the heat exchange tube 400 in the arc-shaped cylinder 130 .

[0056] In this embodiment, the support rod 320 connects the ends of multiple support plates 310, the bending angle of the support rod 320 corresponds to the bending angle of the heat exchange tube 400, the bending radius of the support rod 320 is greater than or equal to the bending radius of the heat exchange tube 400, the bending radius of the heat exchange tube 400 is the bending radius of the heat exchange tube 400 located at the outermost side, and the support rod 320 is located at the outermost side of the heat exchange tube 400, so that the support rod 320 improves the support strength of the support assembly 300 along the circumferential direction, improves the stability of the heat exchange tube 400, and avoids deformation of the heat exchange tube 400.

[0057] In some embodiments provided in this application, Figure 1 、 Figure 2 and Figure 3 As shown, optionally, the folding heat exchanger 10 further includes a pressure detection component, which is disposed inside the shell 100 , and a safety port 140 is disposed on the shell 100 .

[0058] In this embodiment, a pressure sensor is provided within the housing 100 for monitoring the pressure within the housing 100. The heat exchanger also includes a control device, to which the pressure sensor transmits the pressure value within the housing 100. When the pressure value exceeds a threshold, the control device issues an alarm and opens a safety vent 140 on the housing 100, partially releasing the cold medium within the housing 100, reducing the pressure within the housing 100 and improving the safety of the foldable heat exchanger 10.

[0059] Illustratively, the pressure detection component may be a pressure sensor, and a safety relief valve is provided on the safety port 140 , which is connected to the control device.

[0060] In some embodiments provided in this application, Figure 6 As shown, optionally, there are multiple heat exchange tubes 400 , and the multiple heat exchange tubes 400 are divided into multiple groups, and any group of heat exchange tubes 400 is distributed in a polygonal shape on the baffle 200 .

[0061] In this embodiment, multiple heat exchange tubes 400 form a tube bundle. The multiple heat exchange tubes 400 are divided into multiple groups according to their positions. The multiple groups of heat exchange tubes 400 are evenly distributed on the baffle 200. Each group of heat exchange tubes 400 is distributed in a polygonal pattern on the baffle 200, further improving the uniformity of the radial distribution of the heat exchange tubes 400, improving the uniformity of the distribution of the heat medium within the shell 100, and improving the heat exchange effect.

[0062] Illustratively, the polygon may be an equilateral triangle, a square, or a regular hexagon.

[0063] A second embodiment of the present application provides a compressor device, which includes the folding heat exchanger 10 provided by any one of the first embodiments of the present application.

[0064] In this embodiment, it should be noted that the compressor device includes the folding heat exchanger 10 provided in any one of the above embodiments of the present application, and thus has all the beneficial technical effects of the above folding heat exchanger 10.

The baffles 200 are arranged in a staggered pattern. The tie rods 500 are threaded at their ends and connected to fastening nuts, securing the tie rods 500 to the baffles 200 and spacer tubes 600. The cold medium enters through the cold medium inlet 121 of the second cylinder 120. The baffles 200 continuously change the flow direction within the first and second cylinders 110, 120, before exiting through the liquid outlet 111 of the first cylinder 110.

[0067] The first cylinder 110 and the second cylinder 120 are provided with a cold medium inlet 121, a cold medium outlet 111 and a safety vent 140. The safety vent 140 is used to release the pressure when the medium pressure in the shell 100 exceeds the pressure. The first cylinder 110 and the second cylinder 120 are fixed to the upper tube plate 150, the lower tube plate 150 and the arched rotary structure (i.e., the arc cylinder 130) by bolts. Figures 8 to 12 As shown, the arcuate rotary structure consists of an arcuate rotary elbow 131 and a rotary flange 132 . The upper half of the arcuate rotary structure is connected to the first cylinder 110 , and the lower half is connected to the second cylinder 120 .

Studs pass through the bolt holes in the flange and the bolt holes in the tube sheet 150 to connect the pipe box 160 and tube sheet 150. The heat exchange tubes 400 pass through the heat exchange tube holes in the tube sheet 150 and are welded to the tube sheet 150.

[0069] The arc diameter of the baffle 200 is smaller than the inner diameter of the first cylinder 110 and the second cylinder 120. The straight edge of the notch of the baffle 200 is horizontal and transverse. A plurality of heat exchange tube 400 holes and tie rod 500 holes are provided on the baffle 200.
