Description

Technical Field

[0001] This invention relates to the field of heat dissipation technology, and in particular to an oil circuit heat exchange device based on direct evaporative cooling. Background Technology

[0002] Heat exchangers are used for heat exchange between high-temperature and low-temperature media. They are typically used for heat recovery or heat dissipation of high-temperature media. Common heat dissipation methods include air cooling and water cooling. Air cooling utilizes the low density and low heat capacity of air to cool fluids with low heat flux density, while water cooling utilizes the high density and high heat capacity of water to cool fluids with high heat flux density.

[0003] Currently, heat exchangers used for oil circuit cooling typically combine air cooling and water cooling to improve heat dissipation performance. The coolant circulates within a closed pipeline, and after absorbing heat, it needs to be circulated to a larger air-cooled water tank for forced air cooling before circulating back to the workstation for further heat absorption. This obviously increases the size of the heat exchanger, requires more installation space, and reduces the heat exchange capacity per unit area. Therefore, existing heat exchangers suffer from drawbacks such as large size, high cost, and low heat exchange capacity per unit area. This paper proposes an oil circuit heat exchanger based on direct evaporative cooling to address these problems. Summary of the Invention

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0035] Example 1, referring to Figures 1-3 This is the first embodiment of the present invention. This embodiment provides an oil circuit heat exchange device based on direct evaporative cooling, which can improve the heat exchange efficiency per unit area of ​​oil circuit heat dissipation equipment and solve the problems of large installation volume and low heat exchange efficiency per unit area of ​​oil circuit cooling heat exchange equipment. It includes a frame 200, a fan 300, and a control cabinet 400, and also includes a heat exchange mechanism 100, which includes a heat exchange plate 101 and an oil pipe 102 disposed on the heat exchange plate 101. A water tank is disposed at the bottom end of the heat exchange plate 101. 103, and a water distribution tank 104 is provided at the top of the heat exchange plate 101. A water pump 105 is provided between the water tank 103 and the water distribution tank. The cross-section of the oil pipe 102 is D-shaped, and the straight surface of the oil pipe 102 is in close contact with the heat exchange plate 101. The oil pipe 102 is arranged in a U-shaped stacked manner about the heat exchange plate 101. A fixing component 106 is provided between the oil pipe 102 and the heat exchange plate 101. The heat exchange mechanism 100 is vertically arranged in the frame 200. Two sets of fans 300 are stacked on one side of the heat exchange mechanism 100.

[0036] The working principle of this device is explained in conjunction with existing technology and equipment:

[0037] 1. In the prior art, forced air cooling uses a fan 300 to blow air onto the heat dissipation coolant tank. The fins on the heat dissipation coolant tank increase the contact area with the air, thereby achieving rapid cooling. Generally, in order to obtain a sufficiently large heat exchange area, the overall volume of the coolant tank is designed to be large, and the manufacturing difficulty and cost are also high. This device draws water from the bottom water tank 103 to the top water distribution channel 104. The comb grooves 104b of the water distribution channel 104 make the water evenly distributed on each heat exchange plate 101. The multi-layer heat exchange substrate is obtained by stamping. Its main purpose is not to increase the heat exchange area, but to guide the air cooling airflow through the gaps between the heat exchange substrates and through the heat exchange plate 101. A vortex is formed at the specially shaped heat exchange substrate, which causes the water flowing through the heat exchange substrate to evaporate quickly and be carried away. The latent heat of phase change of the evaporating cooling water is used to quickly remove the heat from the oil pipe 102, achieving efficient heat dissipation. For the specific structure, please refer to Embodiment 2.

[0038] 2. In existing technologies, after the liquid-cooled coolant cools the equipment or pipeline, it needs to be circulated to another cooling device for further cooling. Generally, forced air cooling equipment is used to cool the liquid-cooled coolant. Due to the high density and high specific heat capacity of liquid cooling, it is difficult to cool, requiring a larger forced air cooling mechanism, resulting in a large equipment installation volume. The coolant in this device removes the heat from the oil pipe 102 through direct evaporation, and only recovers the part that has not yet evaporated, thus directly eliminating the step and equipment for cooling the coolant, and achieving a smaller equipment volume and higher heat dissipation efficiency.

[0039] In summary, this device can improve the heat exchange efficiency per unit area of ​​oil circuit cooling equipment, solving the problems of large installation volume and low heat exchange efficiency per unit area for oil circuit cooling and heat exchange equipment.

[0040] Example 2, refer to Figures 1 to 7 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a heat exchange mechanism 100 based on a direct evaporative cooling oil circuit heat exchange device. This device features a special stamped structure for the heat exchange plate 101 and is paired with a D-shaped cross-section oil pipe 102. Through circulating water spraying and air-cooled evaporation, it achieves the effect of rapidly removing heat from the oil pipe 102. It includes a heat exchange plate 101, on which a first heat exchange substrate 101a, a second heat exchange substrate 101b, a third heat exchange substrate 101c, and a fourth heat exchange substrate 101c are sequentially stamped. 1d, the fifth heat exchange substrate 101e and the sixth heat exchange substrate 101f, and the stamping direction of the first heat exchange substrate 101a, the second heat exchange substrate 101b and the third heat exchange substrate 101c is opposite to that of the fourth heat exchange substrate 101d, the fifth heat exchange substrate 101e and the sixth heat exchange substrate 101f. The first heat exchange substrate 101a, the second heat exchange substrate 101b, the third heat exchange substrate 101c, the fourth heat exchange substrate 101d, the fifth heat exchange substrate 101e and the sixth heat exchange substrate 101f are arranged in a rectangular array about the heat exchange plate 101.

[0041] The heat exchange plate 101 of this device is made of aluminum, and the first heat exchange substrate 101a, the second heat exchange substrate 101b, the third heat exchange substrate 101c, the fourth heat exchange substrate 101d, the fifth heat exchange substrate 101e, and the sixth heat exchange substrate 101f are obtained by stamping. The manufacturing process is simple and low-cost. (Reference) Figure 6 and Figure 7Each substrate is multi-segmented and layered with a cross-design layout. The multi-gap three-dimensional structure allows the air-cooled airflow to pass directly through the heat exchange plate 101 instead of circulating around its four sides, thereby increasing the speed at which the air-cooled airflow carries away the vapor. At the same time, the special multi-gap three-dimensional structure also forms vortices, which promote the faster evaporation of the flowing coolant and improve heat dissipation efficiency. The D-shaped cross-section structure of the oil pipe 102 ensures that the oil pipe 102 is firmly and stably assembled with the heat exchange plate 101, while increasing the contact area, so that the heat from the oil pipe 102 can be transferred to the heat exchange plate 101 in a timely and efficient manner.

[0042] In addition, covering the surface of the heat exchange plate 101 with fibers can further improve the temporary water storage performance of the heat exchange plate 101, which helps the device to dissipate heat through evaporation.

[0043] The bottom end of the heat exchange plate 101 is inserted into the water tank 103. The top end of the water tank 103 is recessed at the connection of the heat exchange plate 101. A return groove 103a is opened at the bottom of the water tank 103. The side wall of the water tank 103 is also provided with an inlet and outlet interface 103b. The water pump 105 is installed in the water tank 103. A water pipe 105a is connected between the water pump 105 and the water distribution trough 104. The top end of the heat exchange plate 101 is inserted into the water distribution trough 104. A float plate 104a is installed in the water distribution trough 104. A comb groove 104b is opened on both sides of the bottom of the water distribution trough 104.

[0044] The concave design of the top surface of the water tank 103 is intended to concentrate the coolant that cannot be evaporated in time on the heat exchange plate 101 and recover it through the return tank 103a to achieve water saving. The purpose of designing the float plate 104a in the water distribution tank 104 is to float and cover the water surface, so as to avoid liquid turbulence in the water distribution tank 104 due to the continuous pumping of coolant, which is conducive to the stable and uniform distribution of coolant to the heat exchange plate 101.

[0045] The rest of the structure is the same as in Example 1.

[0046] In summary, the device's unique heat exchange plate 101 stamping structure, combined with the D-shaped cross-section oil pipe 102, achieves a small equipment size and high heat dissipation efficiency through circulating water spraying and air-cooled evaporation.

[0047] Example 3, referring to Figure 5 , Figures 8 to 14This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a fixing component 106 for an oil circuit heat exchange device based on direct evaporative cooling. This solves the problem of cumbersome screw and nut assembly operations when assembling the oil pipe 102 and the heat exchange plate 101, and the risk of poor contact between the oil pipe 102 and the heat exchange plate 101 due to loosening of the screw and nut assembly structure. The fixing component 106 includes a first oil cylinder 106a and a second oil cylinder 106b disposed within the first oil cylinder 106a. A bottom cover 106c is provided at the bottom end of the first oil cylinder 106a, and a top cover 106d is provided at the top end of the first oil cylinder 106a. A ring piston 106e is installed inside the hydraulic cylinder 106a, and the ring piston 106e is sleeved with the second hydraulic cylinder 106b. A cylindrical piston 106f is installed inside the second hydraulic cylinder 106b. The cylinder wall of the first hydraulic cylinder 106a has a groove 106a-1, and a first gripper 106g is installed at the top of the groove 106a-1 on the cylinder wall of the first hydraulic cylinder 106a. A second gripper 106h is connected to the peripheral wall of the ring piston 106e, and the second gripper 106h is sleeved with the groove 106a-1. A bracket 106b-1 is installed on the outer wall of the top of the second hydraulic cylinder 106b and is fixedly connected to the inner wall of the top of the first hydraulic cylinder 106a. The first hydraulic cylinder 106a and... The second cylinder 106b is coaxial, and its bottom end is separated from the bottom cover 106c. The top end of the second cylinder 106b is separated from the top cover 106d. An annular piston 106e is positioned at the top of the second gripper 106h and is fitted with a baffle 106k. The baffle 106k is arc-shaped and fits against the inner wall of the first cylinder 106a. The baffle 106k seals and covers the slot 106a-1. The top end of the baffle 106k penetrates the top cover 106d, and the baffle 106k and the top cover 106d are in a sealed sliding contact. A push rod 106j is axially connected to the top end of the cylindrical piston 106f, and a threaded connection is formed between the push rod 106j and the cylindrical piston 106f along their axis. The hole 106e-1 has a sliding groove 106e-2 on its inner wall. The bottom cover 106c is connected to a lead screw 106i, and the peripheral wall of the lead screw 106i has a cut surface 106i-1. The lead screw 106i is inserted into the hole 106e-1. The heat exchange plate 101 has a strip groove 101g, and a strap 106l is threaded between two adjacent parallel strip grooves 101g. The oil pipe 102 is sleeved between the strap 106l and the heat exchange plate 101. The two ends of the strap 106l have slots 106l-1. The first clamp 106g and the second clamp 106h are respectively engaged with the slots 106l-1 at both ends of the strap 106l.

[0048] The fixing component 106 is a hydraulically driven, tool-free fastener used to replace conventional fasteners such as screws and nuts that are cumbersome to operate. It can be simply understood as a miniature hydraulic jack. Its working principle is as follows:

[0049] refer to Figure 5 and Figure 8 This demonstrates the assembly structure of the fixing component 106 tightening the oil pipe 102 and the heat exchange plate 101. During operation, the strap 106l is fitted onto the oil pipe 102 and then passed through the strip groove 101g of the heat exchange plate 101. The first clamp 106g and the second clamp 106h are respectively engaged with the slots 106l-1 at both ends of the strap 106l. The push rod 106j is pressed against the housing of the fixing component 106, and the oil is pushed by the cylindrical piston 106f with a smaller end face area, driving the end face surface... The larger annular piston 106e moves axially along the first oil cylinder 106a and the second oil cylinder 106b, driving the second gripper 106h to move closer to the first gripper 106g, thereby gradually tightening the strap 106l. By applying Pascal's law, a longer stroke of the cylindrical piston 106f is used to obtain a larger driving force of the annular piston 106e, thus allowing the metal strap 106l to be pulled very tight without tools, achieving a tight fit between the D-shaped cross-section oil pipe 102 and the heat exchange plate 101.

[0050] Before further explaining the working principle of the fixing component 106, let's first explain the lead screw 106i and the lead hole 106e-1, referring to... Figure 12 The lead screw 106i and the lead hole 106e-1 in the fixing assembly 106 are not threaded structures, but are composed of annular grooves distributed in layers at positions;

[0051] During the tightening of the 106L strap, refer to Figure 11 , Figure 12 and Figure 14 The non-cut surface 106i-1 portion of the lead screw 106i is slidably connected to the groove 106e-2, while the non-groove portion of the thread hole 106e-1 of the cylindrical piston 106f is in slidable contact with the cut surface 106i-1 of the lead screw 106i, allowing the push rod 106j to be pushed directly and smoothly to tighten the strap 106l. After tightening the strap 106l, the push rod 106j can be rotated ninety degrees to engage the non-cut surface 106i-1 portion of the lead screw 106i with the non-groove portion of the thread hole 106e-1 of the cylindrical piston 106f, thereby locking the position of the cylindrical piston 106f in the axial direction and preventing the first gripper 106g and the second gripper 106h from loosening.

[0052] The rest of the structure is the same as in Example 2.

[0053] In summary, this device effectively solves the problem of cumbersome screw and nut assembly operations when assembling the oil pipe 102 and the heat exchange plate 101, as well as the risk of poor contact between the oil pipe 102 and the heat exchange plate 101 due to loosening of the screw and nut assembly structure.
