Description

Technical Field

[0001] This invention relates to the field of cooling plate technology, and more particularly to a cooling plate. Background Technology

[0002] Cooling plates are typically plate-shaped structures with internal channels through which coolant flows to absorb heat from the heat source, thus achieving the effect of cooling and dissipating heat.

[0003] To prevent coolant backflow in the flow channel, a check valve is usually installed between the inlet and outlet of the cooling plate. However, in the existing technology, the check valve is installed separately on the outside of the cooling plate, that is, the check valve and the cooling plate are separate structures. Therefore, the cooling plate and the check valve need to be assembled separately, which increases the production difficulty and reduces the production efficiency.

[0004] Therefore, there is an urgent need to develop a cooling plate to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a cooling plate that integrates the plate body and the check valve structure, thereby enabling the cooling plate to have a check valve effect and eliminating the need for separate assembly of the cooling plate and the one-way valve.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Cooling plate, including:

[0008] The plate has flow channels, allowing coolant to circulate within them.

[0009] The check valve structure includes a blocking element, a guide element, and a float. The blocking element is arranged around the inner wall of the flow channel along the circumference and has a first through hole. The guide element is connected to the inner wall of the flow channel and a gap is left between the guide element and the inner wall of the flow channel. The blocking element and the guide element are arranged sequentially in the direction of coolant flow. The float is movably arranged between the blocking element and the guide element. When the coolant flows in the direction of flow, the float abuts against the guide element so that the coolant flows through the first through hole and the gap in sequence. When the coolant flows in the opposite direction, the float abuts against the edge of the first through hole to block the first through hole.

[0010] Optionally, the plate body includes a first plate body and a second plate body, the first plate body and the second plate body are fastened together, the first plate body is provided with a first groove, the second plate body is provided with a second groove, the bottom of the second groove is provided with a second through hole, and the first groove, the second groove and the second through hole cooperate to form a flow channel.

[0011] Optionally, the flow guide is disposed at the bottom of the first groove, and a gap is left between the flow guide and the inner wall of the first groove. The blocking member is disposed on the edge or inner wall of the second through hole, and the flow guide is disposed opposite to the first through hole.

[0012] Optionally, the inner wall of the first groove corresponding to the gap is an arc-shaped wall, and the outer wall of the guide is a contour wall, the shape of which is the same as that of the arc-shaped wall.

[0013] Optionally, the flow guide is provided with a flow guide cavity, and the cavity wall of the flow guide cavity is provided with a third through hole and a fourth through hole. The third through hole, the float and the first through hole are coaxially arranged. When the coolant flows in reverse, the coolant enters the flow guide cavity through the fourth through hole and rushes towards the float through the third through hole.

[0014] Optionally, the third through hole is coaxially arranged with the flow guide cavity.

[0015] Optionally, the fourth through hole is opened on the side of the guide member away from the gap, and the axis of the fourth through hole is parallel to the flow direction of the coolant in the second groove when it flows in the opposite direction.

[0016] Optionally, the check valve structure also includes guide members, which are fixed on the inner wall of the flow channel and located between the blocking member and the flow guide member. There are multiple guide members, which are spaced apart along the circumference of the float and slide in cooperation with the float.

[0017] Optionally, a blocking part is provided on the inner wall of the first through hole, and the blocking part extends toward the center of the first through hole. When the coolant flows in reverse, the float abuts against the blocking part.

[0018] Alternatively, the float can be a rubber ball or a plastic ball.

[0019] Beneficial effects:

[0020] The cooling plate provided by this invention has a blocking component, a flow guide component, and a float ball in the flow channel of the plate body. When the coolant flows backward in the flow channel, the float ball abuts against the edge of the first through hole of the blocking component, so that the float ball blocks the first through hole and blocks the reverse flow path of the coolant. When the coolant flows forward in the flow channel, the float ball leaves the edge of the first through hole and abuts against the flow guide component, so that the coolant can flow through the first through hole and the gap in sequence, realizing the forward flow of the coolant. It can be seen that the cooling plate integrates the plate body and the check valve structure, so that the cooling plate has a check valve effect, eliminating the need to assemble the cooling plate and the one-way valve separately, thereby reducing the production difficulty and improving the production efficiency.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0032] This embodiment provides a cooling plate that integrates the plate body and the check valve structure, giving the cooling plate a check valve effect and eliminating the need for separate assembly of the cooling plate and the one-way valve.

[0033] Specifically, such as Figures 1 to 4 As shown, the cooling plate includes a plate body 100 and a check valve structure. The plate body 100 has a flow channel 110, within which coolant can flow. The check valve structure includes a blocking member 210, a flow guide 220, and a float 230. The blocking member 210 is circumferentially arranged around the inner wall of the flow channel 110 and has a first through hole 211. The diameter of the first through hole 211 is smaller than the diameter of the float 230. The flow guide 220 is connected to the inner wall of the flow channel 110. A gap 300 is left between the flow guide 220 and the inner wall of the flow channel 110. The blocking member 210 and the flow guide 220 are arranged sequentially along the flow direction of the coolant. The float 230 is movably arranged between the blocking member 210 and the flow guide 220. When the coolant flows in the forward direction, the float 230 abuts against the flow guide 220 so that the coolant flows through the first through hole 211 and the gap 300 in sequence. When the coolant flows in the reverse direction, the float 230 abuts against the edge of the first through hole 211 to block the first through hole 211.

[0034] Based on the above design, a blocking element 210, a flow guide 220, and a float 230 are provided in the flow channel 110 of the plate 100. When the coolant flows backward in the flow channel 110, the float 230 abuts against the edge of the first through hole 211 on the blocking element 210, thereby blocking the backward flow path of the coolant. When the coolant flows forward in the flow channel 110, the float 230 moves away from the edge of the first through hole 211 and abuts against the flow guide 220, allowing the coolant to flow sequentially through the first through hole 211 and the gap 300, achieving forward flow of the coolant. Thus, this cooling plate integrates the plate 100 and the check valve structure, giving the cooling plate a check valve effect. This eliminates the need for separate assembly of the cooling plate and the one-way valve, thereby reducing production difficulty and improving production efficiency. It should be noted that the coolant can be either cooling water or refrigerant, depending on the actual application.

[0035] Optionally, such as Figures 1 to 5As shown, the plate 100 includes a first plate 120 and a second plate 130. The first plate 120 and the second plate 130 are fastened together. The first plate 120 is provided with a first groove 121, and the second plate 130 is provided with a second groove 131. The bottom of the second groove 131 is provided with a second through hole. The first groove 121, the second groove 131 and the second through hole cooperate to form a flow channel 110. The plate 100 is designed as a split structure, which helps to reduce the difficulty of production and assembly of the cooling plate.

[0036] Optionally, such as Figures 1 to 5 As shown, the flow guide 220 is disposed at the bottom of the first groove 121, and a gap 300 is left between the flow guide 220 and the inner wall of the first groove 121. The blocking member 210 is disposed on the edge or inner wall of the second through hole, and the float 230 is movably disposed in the second through hole. The flow guide 220 and the first through hole 211 are directly opposite each other. This structure allows the flow guide 220 and the blocking member 210 to be disposed on the first plate 120 and the second plate 130 respectively, which helps to reduce the assembly difficulty of the plate 100 and the check structure, thereby improving production efficiency and reducing production costs.

[0037] Furthermore, such as Figures 1 to 5 As shown, the first through hole 211 of the aforementioned blocking member 210 is the liquid inlet of the plate 100. The cooling plate provided in this embodiment also includes a liquid inlet pipe 410 and a liquid outlet pipe 420. The liquid inlet pipe 410 is connected to the side of the second plate 130 away from the first plate 120, and the liquid inlet pipe 410 is connected to the second groove 131 through the first through hole 211. The liquid outlet pipe 420 is connected to the side of the second plate 130 away from the first plate 120, and the liquid outlet pipe 420 is connected to the second groove 131. This structure enables the coolant to enter and exit from the same side of the plate 100.

[0038] Optionally, the inlet pipe 410 and the second plate 130 can be detachably connected or fixedly connected. In this embodiment, the inlet pipe 410 is inserted into the side of the second plate 130 opposite to the first plate 120, that is, the inlet pipe 410 and the second plate 130 are detachable. This facilitates the manufacturing of the first plate 120 and the second plate 130, and also facilitates the assembly of the first plate 120, the second plate 130, and the check valve structure. The outlet pipe 420 and the second plate 130 can be detachably connected or fixedly connected. In this embodiment, the outlet pipe 420 and the side of the second plate 130 opposite to the first plate 120 are an integral structure.

[0039] Optionally, such as Figures 1 to 5As shown, the guide member 220 is provided with a guide cavity 221. The cavity wall of the guide cavity 221 is provided with a third through hole and a fourth through hole 222. The third through hole, the float 230, and the first through hole 211 are coaxially arranged. The diameter of the float 230 is larger than the diameter of the third through hole, so that when the coolant flows in the forward direction, the float 230 abuts against the edge of the third through hole. When the coolant flows in the reverse direction, the coolant enters the guide cavity 221 through the fourth through hole 222 and flows towards the float 230 through the third through hole, thus allowing the reverse-flowing coolant to flow smoothly. The coolant applies a force to the float 230 towards the first through-hole 211. The coaxial design of the third through-hole, float 230, and first through-hole 211 allows the float 230 to move quickly and accurately towards the first through-hole 211 and abut against its edge during the initial stage of backflow. This shortens the response time of the float 230 in blocking the first through-hole 211 during backflow and improves the reliability of the float 230 in blocking the first through-hole 211. Furthermore, this design does not rely on gravity; it only uses the force applied by the backflowing coolant towards the first through-hole 211 to block the float 230. This allows the check valve structure to be in a vertical, horizontal, or even tilted position.

[0040] Preferably, in this embodiment, the check valve structure is in a horizontal state, that is, the blocking member 210, the float 230 and the guide member 220 are on the same horizontal line, so as to avoid the float 230 being affected by gravity and to improve the movement sensitivity of the float 230.

[0041] Furthermore, such as Figures 1 to 5 As shown, the third through hole is coaxially arranged with the flow guide cavity 221, thereby improving the flow guide effect of the flow guide cavity 221 on the counterflowing coolant, reducing the flow resistance of the coolant in the flow guide cavity 221, increasing the flow velocity of the coolant rushing out of the third through hole, and thus increasing the force exerted by the coolant on the float 230, further shortening the response time of the float 230 blocking the first through hole 211 when the coolant flows counterflow.

[0042] Optionally, such as Figures 1 to 5 As shown, the fourth through hole 222 is opened on the side of the guide member 220 away from the gap 300, and the axis of the fourth through hole 222 is parallel to the flow direction of the coolant in the second groove 131 when the coolant flows in reverse. This structural design can reduce the resistance of the coolant flowing into the guide cavity 221 when the coolant flows in reverse, increase the flow rate of the coolant rushing out of the third through hole, and thus shorten the response time of the float ball 230 blocking the first through hole 211 when the coolant flows in reverse.

[0043] Optionally, such as Figures 1 to 5As shown, the inner wall of the first groove 121 corresponding to the gap 300 is an arc-shaped wall, and the outer wall of the guide 220 is a contour wall. The shape of the contour wall is the same as that of the arc-shaped wall. When the coolant flows in the same direction, this structural design can reduce the flow resistance of the coolant, making the coolant flow more smoothly in the gap 300.

[0044] In this embodiment, as Figures 1 to 5 As shown, the guide member 220 is generally cylindrical in shape. One end of the guide member 220 is connected to the bottom of the first groove 121. The third through hole is located at the other end of the guide member 220. A gap 300 is formed between the outer wall of the guide member 220 and the inner wall of the first groove 121. The outer wall of the guide member 220 is a contour wall. The fourth through hole 222 is opened on the side wall of the guide member 220 away from the gap 300. The axis of the fourth through hole 222 is perpendicular to the axis of the guide member 220. The fourth through hole 222 extends from one end of the guide member 220 to the other end to increase the flow rate of the coolant flowing into the guide cavity 221 when it flows in reverse.

[0045] Optionally, such as Figures 1 to 5 As shown, the check valve structure also includes guide members 240, which are fixed to the inner wall of the flow channel 110. The guide members 240 are located between the blocking member 210 and the guide member 220. Multiple guide members 240 are spaced apart along the circumference of the float 230, and each guide member 240 slides in contact with the float 230. The arrangement of the multiple guide members 240 achieves the limiting and guiding effect on the movement of the float 230, ensuring that the movement path of the float 230 coincides with the axis of the first through hole 211. Especially when the coolant flows in reverse, it can improve the accuracy of the float 230 in blocking the first through hole 211. In this embodiment, multiple guide members 240 are all disposed on the wall of the second through hole, and the multiple guide members 240 are evenly distributed along the circumference of the second through hole to improve the limiting effect on the float 230.

[0046] Optionally, such as Figures 1 to 5 As shown, a blocking portion 212 is provided on the inner wall of the first through hole 211. The blocking portion 212 extends towards the center of the first through hole 211. When the coolant flows in reverse, the float 230 abuts against the blocking portion 212 to prevent the float 230 from getting stuck in the first through hole 211. Furthermore, there are multiple blocking portions 212, which are evenly distributed around the circumference of the first through hole 211 to further reduce the probability of the float 230 getting stuck in the first through hole 211.

[0047] Optionally, the float 230 is a rubber ball, which can reduce noise when the float 230 moves between the blocking member 210 and the guide member 220, and when the float 230 collides with the blocking member 210 (or the guide member 220). Of course, in other embodiments, the float 230 can also be a plastic ball.

[0048] The working principle of the check valve structure provided in this embodiment is briefly explained below:

[0049] Please see Figures 1 to 5 When the coolant flows in reverse, the reverse-flowing coolant enters the guide cavity 221 through the fourth through hole 222. The inner wall of the guide cavity 221 guides the coolant, causing the coolant in the guide cavity 221 to rush towards the third through hole and exert a force on the float 230, which is against the edge of the third through hole, in the direction of the first through hole 211. This causes the float 230 to move towards the first through hole 211 and eventually come into contact with the edge of the first through hole 211, thus blocking the reverse flow path of the coolant. When the coolant flows in the same direction, the coolant exerts a force on the float 230 on the side of the float 230 away from the guide member 220, causing the float 230 to move in the direction of the guide member 220 and finally abut against the edge of the third through hole, so that the coolant can pass through the first through hole 211 and the gap 300 in sequence, realizing the forward flow of the coolant in the flow channel 110.

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
