[0022] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0023] Example 1:
[0024] like Figure 1-5 As shown:
[0025] This utility model provides a plate cooler with auxiliary water cooling, including a fixed plate 1, a movable plate 11, fastening bolts 12, a positioning rod 13, and a plate assembly 14; the plate assembly 14 is disposed between the fixed plate 1 and the movable plate 11; the fastening ends of the fastening bolts 12 correspond to the fixed plate 1 and the movable plate 11 respectively; one end of the positioning rod 13 is fixedly connected to the fixed plate 1, and the other end of the positioning rod 13 passes through the movable plate 11; the positioning rod 13 is guided to correspond to the plate assembly 14; it also includes a first heat-conducting plate 2, a spraying device 3, and spiral blades 4; the first heat-conducting plate 2 is laid on top of the plate assembly 14; the spraying device 3 is disposed above the first heat-conducting plate 2 and connected to a water supply pipeline; the spraying end of the spraying device 3 sprays downwards; a plurality of spiral blades 4 are disposed on the upper surface of the first heat-conducting plate 2; the length direction of the spiral blades 4 is parallel to the spraying direction of the spraying device 3.
[0026] When the plate cooler with auxiliary water cooling provided by this utility model is in operation, the spray device 3 connected to the water supply pipeline first sprays cooling water onto the top of the first heat-conducting plate 2, and the cooling water falls onto the spiral blades 4 and the first heat-conducting plate 2. The spiral blades 4 and the first heat-conducting plate 2, as the cooling structure, should be made of materials with high thermal conductivity, such as aluminum. Since the first heat-conducting plate 2 is laid on top of the plate assembly 14, and the spiral blades 4 are connected to the first heat-conducting plate 2, the heat of the plate assembly 14 is transferred to the spiral blades 4 and the first heat-conducting plate 2 through heat conduction. The cooling water sprayed on the first heat-conducting plate 2 absorbs the heat from the first heat-conducting plate 2 and flows downwards from the edge of the first heat-conducting plate 2 to the side of the plate assembly 14. The cooling water sprayed on the spiral blades 4 flows spirally from the top of the spiral blades 4 to the bottom of the spiral blades 4, following the spiral direction of the spiral blades 4. Because the spiral structure of the spiral blades 4 increases the flow path of the cooling water and also increases the surface area compared to the first heat-conducting plate 2, the cooling efficiency of the water-cooled structure can be effectively improved. The cooling water flowing down from the spiral blades 4 and the cooling water on the first heat-conducting plate 2 both flow downwards from the edge of the first heat-conducting plate 2 to the side of the plate assembly 14. Through contact with the side of the plate assembly 14, the cooling water can also absorb some of the heat from the plate assembly 14. Finally, the cooling water flows from the bottom of the plate assembly 14 to the cooling water storage tank below, or it can be collected by a collection device and discharged directly.
[0027] The present invention provides a plate cooler with auxiliary water cooling, which improves heat exchange efficiency by setting spiral blades 4 on the first heat-conducting plate 2 to increase the contact area and contact time between the cooling structure and the cooling water.
[0028] In order to effectively transfer the heat from the first heat-conducting plate 2 to the spiral blade 4, in a preferred embodiment, a heat-conducting plate 41 extends horizontally from the bottom end of the spiral blade 4; the heat-conducting plate 41 is bonded to the first heat-conducting plate 2; and the spiral blade 4 is fixedly connected to the first heat-conducting plate 2 via the heat-conducting plate 41. The heat-conducting plate 41 and the first heat-conducting plate 2 should be fused together, such as by welding or brazing. This connection method can minimize the gaps between the heat-conducting plate 41 and the first heat-conducting plate 2, thereby improving the efficiency of heat conduction.
[0029] The plate cooler with auxiliary water cooling provided by this utility model transfers the heat of the first heat-conducting plate 2 to the spiral blades 4 by setting heat-conducting plates 41, which can increase the contact area between the spiral blades 4 and the first heat-conducting plate 2, effectively improve the efficiency of heat conduction, and thus improve the cooling speed.
[0030] To further increase the contact area between the spiral blade 4 and the cooling water, in a preferred embodiment, heat dissipation holes 42 are provided on the surface of the spiral blade 4; a plurality of heat dissipation holes 42 are arranged sequentially along the spiral direction of the spiral blade 4. When the cooling water flowing on the spiral blade 4 passes through the heat dissipation holes 42, some of the cooling water will flow into the heat dissipation holes 42, and the heat dissipation holes 42 increase the contact area between the spiral blade 4 and the cooling water, thereby improving the heat exchange efficiency between the spiral blade 4 and the cooling water.
[0031] The present invention provides a plate cooler with auxiliary water cooling, which increases the contact area between the spiral blades 4 and the cooling water by setting heat dissipation holes 42, thereby effectively increasing the heat dissipation efficiency of the spiral blades 4.
[0032] The first heat-conducting plate 2 is used to conduct heat from the plate assembly 14. If there is a gap between the plate assembly 14 and the first heat-conducting plate 2, the heat conduction efficiency of both will decrease. In order to ensure that the first heat-conducting plate 2 is in close contact with the plate assembly 14, in a preferred embodiment, a fixing frame 5 and a clamping bolt 51 are also included. The two ends of the fixing frame 5 are fixedly connected to the fixing plate 1 and the movable plate 11, respectively. The fixing frame 5 is mounted above the first heat-conducting plate 2. The fixing frame 5 has a threaded through hole facing the first heat-conducting plate 2. The clamping bolt 51 is threadedly connected to the threaded through hole. The threaded end of the clamping bolt 51 is pressed against the first heat-conducting plate 2. The fixing frame 5 can be fixedly installed on the fixing plate 1 and the movable plate 11 by bolts. After fixing both ends of the fixing bracket 5, the middle part of the fixing bracket 5 is located above the plate group 14. Then, the clamping bolt 51 is screwed into the threaded through hole in the middle of the fixing bracket 5. The threaded end of the clamping bolt 51 presses against the first heat-conducting plate 2, so that the first heat-conducting plate 2 is pressed against the plate group 14, thereby reducing the gap between the first heat-conducting plate 2 and the plate group 14 and increasing the effective contact area between the first heat-conducting plate 2 and the plate group 14.
[0033] The present invention provides a plate cooler with auxiliary water cooling. By setting a fixing frame 5 and installing a clamping bolt 51, the first heat-conducting plate 2 is pressed onto the plate group 14 by the clamping bolt 51, thereby increasing the effective contact area between the first heat-conducting plate 2 and the plate group 14, and thus improving the heat conduction efficiency of the first heat-conducting plate 2.
[0034] After the cooling water is sprayed onto the first heat-conducting plate 2 to absorb heat, it needs to be drained promptly. If the upper surface of the first heat-conducting plate 2 is only a flat surface, some cooling water will accumulate, affecting the cooling efficiency. To drain the cooling water promptly, in a preferred embodiment, a guide channel 21 is provided on the upper surface of the first heat-conducting plate 2; the end of the guide channel 21 corresponds to the side of the plate assembly 14. After the guide channel 21 is provided, the cooling water on the first heat-conducting plate 2 can be quickly collected and guided to both ends of the guide channel 21, flowing downward from the side of the plate assembly 14. During the flow of the cooling water, it comes into contact with the side of the plate assembly 14 and can also absorb some heat, thereby further improving the cooling effect on the plate assembly 14. The cooling water flowing to the bottom of the plate assembly 14 finally falls and enters the cooling water collection device at the bottom, which facilitates subsequent cooling water circulation or discharge treatment.
[0035] To further eliminate the gap between the first heat-conducting plate 2 and the plate assembly 14, in a preferred embodiment, a heat-conducting pad 23 is sandwiched between the first heat-conducting plate 2 and the plate assembly 14. The heat-conducting pad 23 can be made of a rubber material with high thermal conductivity. The relatively soft and deformable heat-conducting pad 23 can fill the gap between the first heat-conducting plate 2 and the plate assembly 14 when the first heat-conducting plate 2 and the plate assembly 14 on both sides are pressed together, thereby further increasing the heat conduction area.
[0036] The plate cooler with auxiliary water cooling provided by this utility model can fill the gap between the first heat-conducting plate 2 and the plate group 14 by setting the heat-conducting pad 23, which can effectively improve the heat conduction efficiency of the first heat-conducting plate 2.
[0037] To prevent the cooling water sprayed by the spraying device 3 from splashing everywhere, in a preferred embodiment, the spraying device 3 is equipped with a splash guard 6 and a water storage tank 62. The water storage tank 62 is located at the bottom of the plate assembly 14. The top of the water storage tank 62 has an opening that covers the bottom of the plate assembly 14. The water storage tank 62 is connected to a drain pipe. The top of the splash guard 6 covers the periphery of the spraying end of the spraying device 3. The bottom of the splash guard 6 covers the top periphery of the plate assembly 14. The bottom of the splash guard 6 also has downwardly extending cover plates 61 on both sides corresponding to the sides of the plate assembly 14. The cover plates 61 cover the sides of the plate assembly 14. The cooling water flows downward from the sides of the plate assembly 14 into the water storage tank 62. The water storage tank 62 can be connected to a drain pipe for discharge, or it can be connected to a circulation system to collect, filter, and re-spray the cooling water.
[0038] The plate cooler with auxiliary water cooling provided by this utility model can prevent the cooling water from splashing when sprayed by setting a splash guard 6, so as to avoid affecting other surrounding equipment.
[0039] To further improve heat dissipation efficiency, in a preferred embodiment, a second heat-conducting plate 63 is attached to both sides of the plate assembly 14; a cover plate 61 is threadedly connected to a fastening bolt 64; the threaded end of the fastening bolt 64 presses the second heat-conducting plate 63 tightly against the plate assembly 14; the second heat-conducting plate 63 has several heat dissipation fins 65 on the side facing away from the plate assembly 14; the heat dissipation fins 65 are arranged laterally; the heat dissipation fins 65 are wavy along the height direction. A heat-conducting pad 23 can also be provided between the second heat-conducting plate 63 and the plate assembly 14 to increase heat conduction efficiency. The second heat-conducting plate 63 is tightly attached to the plate assembly 14 by the fastening bolt 64, transferring the heat of the plate assembly 14 to the heat dissipation fins 65. When the cooling water at the top of the plate assembly 14 flows to the side, it flows over the heat dissipation fins 65. The wavy heat dissipation fins 65 can increase the contact area between the cooling water and the heat dissipation fins 65, thereby improving heat conduction efficiency.
[0040] The plate cooler with auxiliary water cooling provided by this utility model can further increase the heat conduction of the plate group 14 by setting a second heat conduction plate 63 and heat dissipation fins 65 on the side of the plate group 14, thereby improving the heat dissipation efficiency of the plate group 14.
