[0002] A heat exchanger is an energy-saving device that transfers heat between two or more fluids at different temperatures. It transfers heat from a fluid with a higher temperature to a fluid with a lower temperature so that the fluid temperature reaches the specified index of the process.

[0003] When the fan in the heat exchanger works, the gas adsorbed flows upward, and the heat of the liquid in the pipe is taken out only when the gas contacts the pipe. However, the heat exchange efficiency is low, and the heat of the liquid in the pipe cools down slowly. At the same time, the fan will generate noise and vibration when working, which will also affect the surrounding environment and the heat exchanger.

[0025] Figure 1 The schematic diagram of the structure of the water-to-air heat exchanger according to the embodiment of the utility model is shown. Figure 2 Shows Figure 1 Schematic diagram of the structure of the pipe and heat sink at A. Figure 3 A partial schematic diagram of a right view of a water-to-air heat exchanger in an embodiment of the utility model is shown. Figure 4 Shows Figure 3 Enlarged structural diagram of point B in the middle. Figure 5 Shows Figure 3 The enlarged structure diagram of the C in the middle. Figure 1-Figure 5 As shown, the utility model discloses a water-to-air heat exchanger.

[0026] The water-to-air heat exchanger includes a wall 5, a base frame 1, a pipe 2 for circulating liquid, a frame 3 arranged on the base frame 1, and a fan 4 for extracting gas. The pipe 2 is laid in the frame 3. The fans 4 are arranged in parallel on the frame 3. The wall 5 is arranged on the frame 3 around the fans 4. The wall 5 gradually extends inward along the gas flow direction. The frame 3 is connected to the base frame 1 and the fan 4 inlet respectively.

[0027] The frame 3 is arranged at the upper end of the base frame 1. The pipeline 2 is horizontally laid in the frame 3. The fan 4 is arranged in parallel at the upper end of the frame 3. The wall 5 extends from bottom to top toward the fan 4.

[0028] After the fan 4 is working, the gas outside the chassis 1 is sucked into the chassis 1, and the gas in the chassis 1 enters the frame 3, and the gas contacts the pipe 2, and the gas and the liquid in the pipe 2 complete the heat exchange, and the gas in the chassis 1 is discharged through the fan 4. Since the wall 5 surrounds the fan 4, the diffusion of the gas is prevented, and it also plays a role of sound insulation, and the surrounding dust cannot get close to the fan 4. Since the wall 5 of the water-to-air heat exchanger gradually extends inward, the gas gradually accelerates the discharge during the upward movement, thereby improving the heat dissipation efficiency of the liquid in the pipe 2.

[0029] The base frame 1 includes a frame body 11 and a frame plate 12 disposed on the frame body 11. The frame plate 12 has plate holes 13 arranged in parallel. The plate holes 13 are connected to the inner side of the frame body 11 and the outer side of the frame body 11 respectively.

[0030] The frame plate 12 is arranged on the side of the frame body 11. A plate hole 13 is processed on the frame plate 12 by stamping. The plate hole 13 is used for the circulation of gas. When the fan 4 extracts gas, the gas outside the frame body 11 enters the frame body 11 through the plate hole 13.

[0031] The frame 3 has radiating fins 31 arranged in parallel. The radiating fins 31 are bent back and forth. The pipe 2 passes through the radiating fins 31.

[0032] The radiating fins 31 are arranged in a vertical direction, are arranged in parallel in a horizontal direction, and the pipe 2 passes through the radiating fins 31 horizontally.

[0033] After the heat sink 31 is arranged in a vertical direction, the gas can flow from bottom to top along the heat sink 31. By bending the heat sink 31 back and forth, the gas repeatedly touches the heat sink 31 during the flow, slowing down the flow speed of the gas, so that the gas and liquid can fully complete the heat exchange, thereby improving the heat dissipation efficiency of the liquid in the pipeline 2.

[0034] A first mounting rod 51 is arranged on the base frame 1 around the fan 4. A second mounting rod 52 is arranged on the frame 3 around the fan 4. The wall 5 is arranged between the first mounting rod 51 and the second mounting rod 52.

[0035] The upper end of the first mounting rod 51 extends toward the fan 4. The upper end of the second mounting rod 52 extends toward the fan 4. There is a mounting space between the first mounting rod 51 and the second mounting rod 52. The wall 5 is set in the space. The first mounting rod 51 and the second mounting rod 52 complete the position restriction of the wall 5.

[0036] A pressure rod 53 is swingably arranged on the first mounting rod 51. A mounting position 54 is arranged in parallel on the second mounting rod 52. A buckle rod 55 is rotatably arranged on the pressure rod 53. When the pressure rod 53 presses down the wall 5, the buckle rod 55 is embedded in the mounting position 54.

[0037] The pressure rod 53 is swingably arranged at the upper end of the first mounting rod 51. The mounting position 54 is arranged in parallel in the upper end of the second mounting rod 52 in the vertical direction. For example, the mounting position 54 is T-shaped. The inner surface of the mounting position 54 is stepped. For example, the cross section of the buckle rod 55 is rectangular.

[0038] When the pressure rod 53 presses down the wall 5, the swinging buckle rod 55 is embedded in the installation position 54. The shape of the buckle rod 55 matches the installation position 54 to prevent the buckle rod 55 from escaping from the installation position 54, so that the pressure rod 53 continues to press down the wall 5 to prevent the wall 5 from loosening.

[0039] The water-to-air heat exchanger further comprises a pressing plate 57 for pressing the wall 5 and a pressure plate 58 arranged on the pressing plate 57. The pressing rod 53 presses the pressure plate 58 downward.

[0040] The pressing plate 57 and the pressure bearing plate 58 are vertically connected to each other. The pressing plate 57 increases the contact area between the pressing rod 53 and the wall 5 to avoid crushing the wall 5.

[0041] The wall 5 includes blocks 56 that are connected to each other.

[0042] The wall 5 is integrally formed.

[0043] The wall 5 can be formed by splicing blocks 56, or the wall 5 can be formed in one piece.

[0044] The block 56 is a sound-absorbing sponge, so that the wall 5 has a sound-absorbing function. When the block 56 is damaged and needs to be replaced, only the damaged block 56 needs to be replaced, and the wall 5 does not need to be replaced as a whole.

[0045] When the wall 5 is a metal plate, it plays a role of protection and dust prevention. By adopting an integral molding process, there will be no gaps in the wall 5.

[0046] The water-to-air heat exchanger further includes a clamp block 6, a clamp rod 61 penetrating the clamp block 6, and a locking member 62 for fixing the clamp block 6. The first laminate 32 is arranged in parallel on the frame 3. The second laminate 33 is arranged in parallel on the first mounting rod 51. The first laminate 32 and the second laminate 33 are stacked alternately. The clamp block 6 compresses the first laminate 32 and the second laminate 33. The locking member 62 is threadedly connected to the clamp rod 61.

[0047] The first laminate 32 is inserted between adjacent second laminates 33, and the second laminate 33 is inserted between adjacent first laminates 32. The clamping block 6 is relatively clamped on the first laminate 32 and the second laminate 33. The clamping rod 61 passes through the relatively distributed clamping blocks 6. The locking member 62 is threadedly connected to both ends of the clamping rod 61. The locking member 62 is tightened, and the locking member 62 presses the clamping block 6, so that the clamping block 6 clamps and fixes the first laminate 32 and the second laminate 33.

[0048] The first mounting rod 51 and the frame 3 are elastically connected by the staggered stacking of the first stack 32 and the second stack 33. The first mounting rod 51 is directly mounted on the base frame 1, and the first mounting rod 51 has a good pressure bearing capacity. The fan 4 is mounted on the frame 3, and the fan 4 will cause the frame 3 to shake when it is working, which will affect the liquid in the pipeline 2. The first stack 32 and the second stack 33 are staggered and stacked to reduce the shaking of the frame 3.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
