Description

Technical Field

[0001] This utility model belongs to the technical field of human body thermal protection equipment, specifically referring to a polymer water-cooled sheet. Background Technology

[0002] To improve working conditions in high-temperature environments, workers are usually equipped with wearable cooling devices such as water-cooled and air-cooled suits.

[0003] Chinese invention patent application number "2023116439910" discloses a cooling suit, including a wearable body, a flexible tube, a liquid storage tank, a liquid pump, and a cooling device. The wearable body is made of an elastic material, and the flexible tube is coiled from the inside out on the wearable body and in contact with the wearable body surface. The liquid storage tank, liquid pump, and cooling device are fixed to the wearable body. The liquid storage tank is connected to one end of the flexible tube and also to the liquid pump. The cooling device is connected to the liquid pump and the other end of the flexible tube, so that when the liquid pump is working, the liquid cooled by the cooling device is sent into the flexible tube for heat exchange.

[0004] The aforementioned cooling garment achieves cooling through contact between the flexible tube and the human body. When worn close to the skin, it can cause a noticeable foreign body sensation and poor comfort. Furthermore, this solution only has a heat dissipation effect at the location of the flexible tube, but the contact area between the flexible tube and the human body is limited, resulting in a small heat dissipation area and poor heat dissipation performance.

[0005] Chinese invention patent application number "2023106577488" discloses a split-type water-circulating cooling backpack, which reveals a detachable water circulation pipe plate. The water circulation pipe plate is composed of two polymer films, which are pressed together at their edges to fix them in place. The two polymer films are pressed together along two parallel lines in the middle to form a water circulation pipe, and are provided with inlet and outlet water outlets. By using a pipe plate composed of polymer films instead of water pipes, the water cooling area is larger, the contact area with the human body is also larger, the heat dissipation and cooling effect is better, and the foreign body sensation is effectively reduced when in contact with the human body, improving comfort.

[0006] However, in the above solution, the inlet and outlet pipes are heat-welded onto a membrane. During use, the inlet pipe experiences excessive local pressure when water enters, causing the inlet area to bulge, reducing user comfort. Furthermore, prolonged high pressure can lead to leakage in the inlet area, reducing product lifespan. In this solution, water flow is still limited to a pre-defined tubular route, resulting in a small contact area between the cold water and the body, leading to insufficient heat dissipation. To ensure the water circulation pipe's airtightness, the membrane is typically made of an impermeable material, resulting in poor breathability and hindering heat dissipation, causing stuffiness and discomfort. Additionally, each water circulation pipe in this solution requires a separate cooling unit. When multiple areas need cooling (such as the body, legs, and head), multiple cooling units are required, making it very inconvenient. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to reduce the local pressure at the water inlet of the water-cooling plate, increase the contact area between cold water and the human body, and improve the ease of use.

[0008] The objective of this utility model can be achieved through the following technical solutions: A polymer water-cooling plate includes two polymer films, upper and lower, which are pressed together at their edges to seal them together. A water supply channel is formed between the two polymer films. One of the polymer films has an inlet and an outlet. Pipes are pressed and fixed at the inlet and outlet. Several hot-pressing points are spaced around the inlet and / or outlet. The plate also includes several pressing areas and pressing lines formed by pressing the two polymer films together. The pressing areas are evenly spaced.

[0009] The inlet is used to connect water pipes. Cold water or other heat dissipation fluid passes through the inlet. The hot-pressing points are formed by hot-pressing two polymer films. These points at the inlet and outlet divide the entire water inlet area into multiple channels, thus evenly distributing the local pressure during water inflow or outflow, preventing bulging, reducing leakage, and extending product lifespan. The shape or number of channels depends on the distribution pattern of the hot-pressing points. The shape of the pressing zone can be dot-shaped or strip-shaped, etc. The evenly spaced pressing zones create channels for cold water to circulate inside the water-cooled plate. In this design, except for the pressing zones, pressing lines, and air vents, the entire water-cooled plate is filled with cold water. The flow channel provides a larger heat dissipation area in contact with the human body, resulting in better heat dissipation. The pressure line guides the water flow and also provides some pressurization. The vents further increase breathability and can be used with a fan-operated garment to further enhance heat dissipation. This solution allows multiple water-cooling fins to be connected in series via pipe openings and water pipes. The overall shape of the water-cooling fins can be adjusted according to the actual usage scenario, such as clothing, pants, hats, table mats, and electronic product heat dissipation. A single cooling system can circulate heat dissipation to multiple areas, and the combination is more flexible, allowing for free combination and use according to actual needs, making operation more convenient.

[0010] In this polymer water-cooled sheet, the polymer water-cooled sheet is rectangular in shape and also includes a dividing line formed by pressing two polymer films together. The dividing line divides the polymer water-cooled sheet into a first flow domain and a second flow domain. The first flow domain has a first water inlet at the bottom and a first water outlet at the top; the second flow domain has a second water inlet at the top and a second water outlet at the bottom.

[0011] In this solution, the first inlet is connected to the refrigeration equipment. Cold water flows into the first flow area from the first inlet and out from the first outlet. At this time, the first outlet can be connected to other water-cooled plates for multi-area circulating refrigeration. The water then flows into the second flow area through the second inlet and out from the second outlet. At this time, the water inlet and outlet of the entire water circulation system are on the same water-cooled plate, which is convenient for users to operate. When it is not necessary to connect other water-cooled plates, the first outlet and the second inlet can also be connected through water pipes to realize water circulation of a single plate.

[0012] Furthermore, the first flow area is equipped with several horizontally arranged pressure lines. One end of each pressure line connects to the left or right side of the first flow area, while the other end is left open. Adjacent pressure lines work together to form an S-shaped flow channel. The multiple spaced pressure lines work together to form a serpentine water flow channel within the first flow area, slowing down the water flow and allowing the cold water to fully diffuse throughout the entire space of the first flow area, increasing the contact area with the human body and improving the heat dissipation effect.

[0013] Preferably, the first water inlet is located at the lower part of the first flow area. The first flow area and / or the second flow area are provided with vents penetrating the two polymer films. The edges of the vents are sealed by pressing and sealing the two polymer films together. The size of the vents is larger than the size of the pressed area. The large-sized vents can further increase air permeability and can also be used with a fan cover to further improve the heat dissipation effect. The vents are located between the first water inlet and the first water outlet, and between the second water inlet and the second water outlet. At this time, the vents can also play a certain role in guiding the water flow, so that the water flow can be fully diffused into the interior of the water-cooling plate.

[0014] In this polymer water-cooled plate, the polymer water-cooled plate is rectangular in shape and includes two dividing lines formed by pressing two polymer films together. The dividing lines are perpendicular to each other and intersect, dividing the polymer water-cooled plate into a first flow domain, a second flow domain, a third flow domain, and a fourth flow domain. The first flow domain has a first water inlet at the bottom and a first water outlet at the top; the second flow domain has a second water inlet at the bottom and a second water outlet at the top; the third flow domain has a third water inlet at the top and a third water outlet at the bottom; and the fourth flow domain has a fourth water inlet at the top and a fourth water outlet at the bottom.

[0015] The crisscrossing dividing lines divide the water-cooled plate into four flow zones. Cold water flows into the first flow zone from the first inlet, then extends outward to other water-cooled plates from the first outlet, flows back into the second flow zone from the second inlet, and then flows into other water-cooled plates from the second outlet, and so on. Each flow zone can be extended outward to accommodate other water-cooled plates, and all of them eventually flow back to the current water-cooled plate. Users can combine and use them in an orderly and convenient manner.

[0016] In this polymer water-cooling sheet, the sheet comprises an elongated flow channel and a circular rotating section, which are integrally formed and connected. The flow channel has a longitudinal pressing line extending into the rotating section, dividing it into left and right parts. The bottom of each part has an inlet and an outlet, respectively. The rotating section has a circular through-hole at its center, the size of which is larger than the size of the pressing area. This water-cooling sheet is suitable for cooling the head with a hat. The circular rotating section is installed inside the hat, conforming to its shape. Cold water flows from the inlet into the right flow channel, circulates through the circular rotating section, flows around the through-hole into the left flow channel, and exits through the outlet. The large through-hole increases air permeability while reducing the weight of the water-cooling sheet.

[0017] Furthermore, the rotating part is provided with several pressure lines along its radial direction, and at least one gap is left between the two ends of the pressure lines and the through holes or the edge of the rotating part. While guiding the water flow, the gaps left between the pressure lines and the through holes and / or the edge of the rotating part allow water to flow through, which pressurizes the water flow and promotes the water flow rotation.

[0018] Preferably, the left and right edges of the flow channel are concave arc-shaped. The concave arc-shaped flow channel reduces the space for water flow, which can pressurize the water flow and promote the flow and circulation of cold water.

[0019] In this polymer water-cooled plate, the plate is a transversely elongated strip. One transverse edge of the plate extends outward to form a protrusion, the edge of which is pressed and sealed. The protrusion is connected to the main body of the plate. A longitudinal pressing line extends into the plate, dividing the protrusion into left and right sections. Each section has an inlet and an outlet. A transverse pressing line connects to the longitudinal pressing line in a T-shape. Openings for water flow are left between the ends of the transverse pressing line and the edge of the plate. This water-cooled plate is suitable for cooling cylindrical objects such as necks. When unfolded, the plate is T-shaped, and the pressing line within it is also T-shaped, allowing water to circulate and cool in a T-shape around the pressing line, ensuring thorough diffusion to every part of the plate.

[0020] In this polymer water-cooled sheet, a vent hole is provided in the center of the lamination zone, penetrating the two polymer films. The size of the vent hole is smaller than that of the lamination zone. The vent hole formed by hollowing out the center of the lamination zone makes full use of the limited space on the water-cooled sheet, increasing the breathability of the water-cooled sheet without occupying the heat dissipation area, thus improving the user's wearing comfort.

[0021] Compared with the prior art, the technical effects of this utility model are as follows: This solution divides a large water inlet area into multiple water inlet channels through hot pressing points, thereby evenly distributing the local pressure during water inlet or outlet, preventing bulging, reducing leakage, and extending the product's service life.

[0022] This solution creates a channel for the flow of cooling water inside the water-cooled plate by evenly spaced pressing zones. In other words, apart from the pressing zones, pressing lines, and air vents, the entire water-cooled plate is a channel for cooling water, resulting in a larger heat dissipation area in contact with the human body and better heat dissipation effect.

[0023] This solution makes full use of the limited space on the water-cooling plate by setting a vent in the center of the pressing area. It increases the breathability of the water-cooling plate and improves the user's wearing comfort without taking up heat dissipation area.

[0024] The pressure lines in this design guide the water flow and also provide some pressure. The vents further increase air permeability and can be used in conjunction with a fan cover to further improve heat dissipation.

[0025] This solution allows multiple water-cooled fins to be connected in series via pipe outlets and water pipes. The overall shape of the water-cooled fins can be adjusted according to the actual usage scenario. Multiple areas can be circulated and cooled with just one set of cooling equipment. Moreover, the combination is more flexible and can be freely combined according to actual needs, making operation more convenient. Attached Figure Description

Detailed Implementation

[0033] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0034] like Figure 1 As shown, a polymer water-cooling plate includes two polymer films, upper and lower, whose edges are sealed together by heat pressing. One of the polymer films has an inlet 11 and an outlet 12, and a pipe port 2 is pressed and fixed at the inlet 11 and outlet 12. For easy observation, Figure 1The inlet 11 is not shown as a pipe port 2. Several heat-pressing points 13 are spaced around the inlet 11 and / or outlet 12. Each heat-pressing point 13 is formed by two polymer films connected by heat pressing. The pipe port 2 is used to connect water pipes. Cold water or other cooling fluid passes through the inlet 11 via the pipe port 2. The heat-pressing points 13 at the inlet and outlet divide the entire water inlet area into multiple water inlet channels, thereby evenly distributing the local pressure during water inlet or outlet, preventing bulging, and reducing leakage. It also includes several points that press the two polymer films together... The pressure-sealing zone 3, formed by the bonding process, can be dotted or strip-shaped, etc. The pressure-sealing zones 3 are evenly spaced, creating channels for cold water flow inside the water-cooling plate. This facilitates the even diffusion of cold water to all corners of the water-cooling plate. In this design, except for the pressure-sealing zone 3, pressure lines 4, and air vents 7, the entire water-cooling plate serves as a cold water flow channel, resulting in a larger heat dissipation area in contact with the human body and better heat dissipation. A vent 31, smaller than the pressure-sealing zone 3, is located in the center of the pressure-sealing zone 3, connecting two polymer films. By placing the vent in the pressure-sealing zone, the limited space on the water-cooling plate is fully utilized. This increases the breathability of the water-cooling plate without occupying heat dissipation area, improving user comfort.

[0035] Example 2:

[0036] As a preferred option, such as Figure 2 As shown, the polymer water-cooled plate is rectangular in shape and includes a dividing line 5 formed by pressing two polymer films together. The dividing line 5 separates the polymer water-cooled plate into a first flow domain 61 and a second flow domain 62. The first flow domain 61 has a first inlet 111 at the bottom and a first outlet 121 at the top. The second flow domain 62 has a second inlet 112 at the top and a second outlet 122 at the bottom. The first inlet 111 is connected to the refrigeration equipment, and water flows out from the first outlet 121. At this time, the first outlet 121 can be connected to other water-cooled plates for multi-region circulating refrigeration, and the water flows into the second flow domain 62 through the second inlet 112. Then it flows out from the second outlet 122. At this time, the water inlet and outlet of the entire water circulation system are on the same water-cooled plate, which is convenient for users to operate. When it is not necessary to connect other water-cooled plates, the first outlet 121 and the second inlet 112 can also be connected through water pipes to realize water circulation of a single plate. In this embodiment, the area of ​​the first flow field 61 is larger than the area of ​​the second flow field 62. Cold water flows into the first flow field 61 from the first inlet 111. The water in the first flow field 61 is relatively colder than the water in the second flow field 62. Increasing the area of ​​the first flow field 61 increases the contact area between the low temperature water and the human body as much as possible, thereby improving the cooling effect.

[0037] In this embodiment, three horizontally arranged pressing lines 4 are provided in the first flow area 61. From bottom to top, the right end of the first pressing line 4 is connected to the right edge of the first flow area 61, and the left end of the pressing line 4 is connected to the left edge of the first flow area 61, and the right end of the pressing line 4 is connected to the right edge of the first flow area 61, and the left end of the pressing line 4 is connected to the right edge of the first flow area 61, and the left end of the pressing line 4 is connected to the right edge of the first flow area 61, and the left end of the pressing line 4 is connected to the left edge of the first flow area 61. The three spaced pressing lines 4 cooperate with each other to form a serpentine water flow channel in the first flow area 61, which slows down the flow rate of the water and allows the cold water to fully diffuse into the entire space in the first flow area 61, increasing the contact area with the human body and improving the heat dissipation effect.

[0038] Example 3:

[0039] As a preferred option, such as Figure 3 As shown, the polymer water-cooled sheet is rectangular in shape and includes a dividing line 5 formed by pressing two polymer films together. The dividing line 5 separates the polymer water-cooled sheet into a first flow area 61 and a second flow area 62. The first flow area 61 has a first water inlet 111 at the bottom and a first water outlet 121 at the top. The second flow area 62 has a second water inlet 112 at the top and a second water outlet 122 at the bottom. The first water inlet 111 is located at the lower left of the first flow area 61. The first flow area 61 and / or the second flow area 62 have vents 7 that penetrate the two polymer films. The edges of the vents 7 are pressed and sealed by the two polymer films. The shape of the vents 7 can be set to be circular, square, or rectangular, etc., according to actual needs. The size of the vents 7 is larger than the size of the pressing area 3. Large-sized vents 7 further increase breathability and can also be used with a fan cover to further improve heat dissipation. At this time, the first water inlet 111 and the first water outlet 121 are located diagonally opposite each other, and the vents 7 are located between the first water inlet 111 and the first water outlet 121, and between the second water inlet 112 and the second water outlet 122. The vents 7 can also guide the water flow to a certain extent, so that the water flow can be fully diffused into the interior of the water-cooling plate. In this embodiment, the area of ​​the first flow region 61 is larger than the area of ​​the second flow region 62. Cold water flows into the first flow region 61 from the first water inlet 111. The water in the first flow region 61 is relatively colder than the water in the second flow region 62. Increasing the area of ​​the first flow region 61 maximizes the contact area between the low-temperature water and the human body, thereby improving the cooling effect.

[0040] Example 4:

[0041] As a preferred option, such as Figure 4As shown, the polymer water-cooling sheet is rectangular in shape and includes two dividing lines 5 formed by pressing two polymer films together. The dividing lines 5 are perpendicular to each other and intersect, dividing the polymer water-cooling sheet into a first flow region 61, a second flow region 62, a third flow region 63, and a fourth flow region 64. The first flow region 61 has a first water inlet 111 at the bottom and a first water outlet 121 at the top; the second flow region 62 has a second water inlet 112 at the bottom and a second water outlet 122 at the top; the third flow region 63 has a third water inlet 113 at the top and a third water outlet 123 at the bottom; the fourth flow region 64 has a fourth water inlet 114 at the top and a fourth water outlet 124 at the bottom. Each flow region has two pressing lines 4. The layout and function of the pressing lines 4 are similar to those in Example 2 and will not be described again here. In this system, the first outlet 121 of the first flow zone 61 and the second inlet 112 of the second flow zone 62 face the same direction. The third outlet 123 of the third flow zone 63 and the fourth inlet 114 of the fourth flow zone 64 face the same direction, while the first outlet 121 and the fourth inlet 114 face opposite directions. This facilitates the connection of other water-cooled plates via pipes on both sides of the water-cooled plate. The crisscrossing dividing lines 5 divide the water-cooled plate into four flow zones. Cold water flows into the first flow zone 61 from the first inlet 111, then extends outward from the first outlet 121 to other water-cooled plates, flows back into the second flow zone 62 from the second inlet 112, and then flows into other water-cooled plates from the second outlet 122, and so on. Each flow zone can be extended outward to accommodate other water-cooled plates, and all water eventually flows back to the current water-cooled plate. Users can combine and use these systems in an orderly and convenient manner. In this embodiment, the pressing line 4 and the pressing area 3 are located in the same row, forming a structure in which the pressing line 4 passes through the pressing area 3. Setting the pressing line 4 in such a way as to pass through the pressing area 3 can further reduce the obstruction of the water flow by the pressing line 4, making the water flow smoother, and there is no need to consider the distance between the pressing line 4 and the edge of the pressing area 3 due to the setting of the pressing line 4.

[0042] Example 5:

[0043] As a preferred option, such as Figure 5As shown, the water-cooling sheet in this embodiment is suitable for cooling the head with a hat. The polymer water-cooling sheet includes a long strip-shaped flow channel 65 and a circular rotating part 66. The flow channel 65 and the rotating part 66 are integrally formed and connected. The flow channel 65 has a pressing line 4 along its longitudinal direction and extends into the rotating part 66. The pressing line 4 divides the flow channel 65 into left and right parts. The bottom of the two parts is provided with an inlet 11 and an outlet 12, respectively. The rotating part 66 has a circular through hole 67 in its center. The edge of the through hole 67 is formed by hot-pressing two thin films. The size of the through hole 67 is larger than the size of the pressing area 3. The through hole 67 can guide the water flow to rotate, making it easy to fix with the hat. The large through hole 67 increases the breathability and also reduces the weight of the water-cooling sheet, reducing pressure on the head. Part 66 is installed inside the cap, conforming to the shape of the cap. Cold water flows into the right-side flow channel part 65 from the inlet 11, and rotates through the circular rotating part 66, flowing around the through hole 67 into the left-side flow channel part 65, and then flows out through the outlet 12. The rotating part 66 is also provided with three pressure lines 4 along its radial direction. A total of four pressure lines 4 evenly divide the rotating part 66 into four equal parts. The two ends of the pressure lines 4 in the rotating part 66 leave gaps with the through hole 67 and / or the edge of the rotating part 66. While guiding the water flow, the gaps left between the pressure lines 4 and the through hole 67 and / or the edge of the rotating part 66 allow water to flow through, which has a pressurizing effect on the water flow and promotes the water flow rotation. The left and right edges of the flow channel part 65 are concave arc-shaped, which reduces the space for water to flow through, and can pressurize the water flow, promoting the flow and rotation of cold water.

[0044] Example 6:

[0045] As a preferred option, such as Figure 6 As shown, the water-cooled plate of this scheme is suitable for cooling cylindrical objects such as necks. The polymer water-cooled plate is a horizontal strip shape used to wrap around the cylindrical object. The horizontal edge of the polymer water-cooled plate at the bottom extends outward to form a protrusion 68. The edge of the protrusion 68 is pressed and sealed. The protrusion 68 is connected to the main body of the polymer water-cooled plate. When the water-cooled plate is unfolded, it is T-shaped. The protrusion 68 has a pressing line 4 extending into the polymer water-cooled plate along the longitudinal direction and divides the protrusion 68 into two parts, left and right. The two parts are respectively provided with a water inlet 11 and a water outlet 12. The polymer water-cooled plate has a pressing line 4 along the horizontal direction and connects with the pressing line 4 along the longitudinal direction to form a T-shape. The two ends of the horizontally set pressing line 4 are left with openings for water to pass through between the edges of the polymer water-cooled plate, so that the water flows in a T-shape around the pressing line in the water-cooled plate for cooling and fully diffuses to every part of the water-cooled plate.

[0046] Preferably, the outer periphery of the polymer water-cooling sheet is also provided with several fixing holes 8 for fixing and installing the water-cooling sheet.

[0047] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection defined by the claims of the present utility model.
