Description

Technical Field

[0001] This utility model relates to the field of heat dissipation, specifically to a water circulation heat dissipation device for glass fiber production. Background Technology

[0002] Glass fiber is a high-performance inorganic non-metallic material with advantages such as good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength. The production of glass fiber generates temperatures of 1350~1400 degrees Celsius, therefore a heat sink is needed to quickly dissipate the heat; otherwise, heat will accumulate, causing the operating temperature of the heat source to rise.

[0003] A conventional heat dissipation device has a structure similar to a computer air cooler, consisting of a base and heat dissipation fins. The lower surface of the base is in contact with the heat source, while the upper surface has multiple heat dissipation fins. The base absorbs the heat generated by the electronic components and transfers it to the heat dissipation fins, which then dissipate the heat from the base into the surrounding air, thereby reducing the temperature of the heat source.

[0004] The aforementioned heat dissipation methods are not very efficient. Therefore, patent number 202410189031.X discloses a U-shaped water circulation cooling device and its heat dissipation method. It includes a cooling device, cooling fins disposed on the cooling device, a first pipe connected to the cooling device, and a second pipe connected to the cooling device. The cooling device has a first groove and a second groove. The first pipe is connected to the first groove; the second pipe is connected to the second groove; the first pipe and the second pipe are arranged opposite to each other. Cooling grooves are formed within the cooling fins. A baffle is disposed in the middle of each cooling groove; the baffle is located between the first groove and the second groove. The liquid quickly removes heat from the base, and the heat is dissipated into the surrounding air by the cooling fins.

[0005] In the aforementioned patent's technical solution, the sealed connection between the heat sink and the cooling device is not stable enough. During use (transportation, installation, maintenance), the heat sink and the cooling device are prone to separation, causing the coolant to leak from the gap between the heat sink and the cooling device. At the same time, in this technical solution, the first pipe and the second pipe are directly connected to the first slot and the second slot, which are connected to the heat dissipation plate. This results in a faster flow rate on the heat sink near the outlet of the first pipe and the inlet of the second pipe, while the flow rate on the remaining heat sinks is relatively lower. Therefore, the overall heat dissipation efficiency of the heat sink is uneven, and it is impossible to achieve higher heat dissipation efficiency. Utility Model Content

The upper end face of the head end of the heat dissipation fins is seamlessly fixed to the bottom of the external C-shaped grooves, and the upper outer surface of the head end of the heat dissipation fins is seamlessly fixed to the inner wall of the external C-shaped grooves.

[0021] Furthermore, the upper part of the head end of the heat dissipation fin tube is provided with a notch; the notch is inserted into the outer tube and communicates with the inner cavity of the outer tube; the projections of the upper and lower end faces of the notch are located in the side wall of the outer C-shaped groove; the projection of the lower end face of the notch is located in the side wall of the inner C-shaped groove; the lower part of the head end of the heat dissipation fin tube is inserted through the outer tube and inserted into the inner tube.

[0022] The upper outer surface of the inner tube is provided with a baffle strip to block the upper part of all the inner C-shaped grooves.

[0024] A flow-limiting strip is installed on the upper surface of the flow-blocking strip, with its side surface fitting against the front inner surface of the outer tube, controlling the flow area between the outer C-shaped groove and the notch at the head end of each heat dissipation fin.

[0025] Furthermore, the current sharing unit also includes:

[0026] A flow equalization strip is installed inside the outer tube and fixed to the outer surface of the inner tube. The flow equalization strip is located between the end of the first liquid tube and the upper part of the head end of each heat dissipation fin tube, controlling the flow area between the end of the first liquid tube and the upper part of the head end of each heat dissipation fin tube.

[0033] Due to the adoption of the above technical solution, this utility model has the following advantages:

[0034] 1.

[0035] 2.

[0055] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0056] As shown in Figures 1 to 9, a water circulation and heat dissipation device for glass fiber production includes:

[0057] First liquid tube;

[0058] Second liquid tube;

[0059] The outer tube has a rectangular tubular structure, and the end of the first liquid tube is connected to the inner cavity of the outer tube;

[0060] The inner tube is fixedly installed inside the outer tube, forming a rectangular tubular structure. The end of the second liquid tube passes through the outer tube and communicates with the inner cavity of the inner tube.

[0061] Several flat heat dissipation fins are evenly spaced; the tail end of each heat dissipation fin is closed; the upper part of the head end of each heat dissipation fin is inserted into an outer tube and communicates with the inner cavity of the outer tube; the lower part of the head end of each heat dissipation fin is inserted through the outer tube and into an inner tube and communicates with the inner cavity of the inner tube; the outer surface of each heat dissipation fin is seamlessly fixed to the inserted outer and inner tubes.

[0062] The flow equalization unit is installed inside the outer tube, located between the end of the first liquid pipe and the upper part of the head end of each heat dissipation fin tube, and controls the flow area between the end of the first liquid pipe and the upper part of the head end of each heat dissipation fin tube.

[0063] Two inner sealing plates are installed at both ends of the inner tube to seal both ends of the inner tube;

[0064] Two outer sealing plates are installed at both ends of the outer tube to seal both ends of the outer tube.

[0065] By inserting the heat dissipation fins into the inner and outer tubes, the heat dissipation fins have a larger contact area with the inner and outer tubes, meaning there are more areas that can be fixed, which can effectively improve the connection strength between the heat dissipation fins and the inner and outer tubes.

[0066] A flow equalization unit controls the flow area between the end of the first liquid pipe and the upper part of the head of each heat dissipation fin, allowing the liquid flowing from the end of the first liquid pipe to flow evenly into each heat dissipation fin, or for a relatively equal amount of liquid to flow from each heat dissipation fin into the end of the first liquid pipe. The amount of liquid flowing through each heat dissipation fin per unit time is approximately the same, and the heat dissipation of each heat dissipation fin per unit time is not significantly different, resulting in more uniform heat dissipation and effectively improving overall heat dissipation efficiency.

[0067] The inlet and outlet of the cooling liquid are isolated by inner and outer pipes respectively, so that the height of the connection between the first liquid pipe and the second liquid pipe on the outer pipe can be arbitrarily selected. That is, the horizontal height of the first liquid pipe and the second liquid pipe on the outer pipe can be kept consistent. This device has fewer installation restrictions and can better adapt to different installation environment needs.

[0068] As shown in Figure 10, in this embodiment, the inner sealing plate is seamlessly connected to the outer wall of the heat dissipation fin tube located on the outside.

[0069] The inner sealing plate can be integrated with the outer heat dissipation fin tube body, reducing the number of parts and connecting seams, and improving product stability.

[0070] As shown in Figure 5, in this embodiment, the front outer side and lower outer side of the inner tube are respectively attached and fixed to the front inner side and lower inner side of the outer tube;

[0071] The inner tube is provided with several inner C-shaped grooves corresponding to the heat dissipation fins. The lower end face of the head end of the heat dissipation fins is seamlessly fixed to the bottom of the inner C-shaped grooves, and the lower outer surface of the head end of the heat dissipation fins is seamlessly fixed to the inner wall of the inner C-shaped grooves.

[0072] The outer tube is provided with several external C-shaped grooves corresponding to the heat dissipation fins. The upper end face of the head end of the heat dissipation fins is seamlessly fixed to the bottom of the external C-shaped grooves, and the upper outer surface of the head end of the heat dissipation fins is seamlessly fixed to the inner wall of the external C-shaped grooves.

[0073] The inner and outer C-shaped grooves allow for the insertion of the heat dissipation fins, which facilitates better connection between the heat dissipation fins and the inner and outer tubes.

[0074] As shown in Figures 6 to 9, in this embodiment, the upper part of the head end of the heat dissipation fin tube is provided with a notch; the notch is inserted into the outer tube and communicates with the inner cavity of the outer tube; the projections of the upper and lower end faces of the notch are located in the side wall of the outer C-shaped groove; the projection of the lower end face of the notch is located in the side wall of the inner C-shaped groove; the lower part of the head end of the heat dissipation fin tube is inserted through the outer tube and inserted into the inner tube;

[0075] The upper outer surface of the inner tube is provided with a baffle strip to block the upper part of all the inner C-shaped grooves.

[0076] The lower part of the head end of the heat dissipation fin is inserted through the outer tube and into the inner tube, forming a part in the inner tube that guides the flow of liquid.

[0077] As the liquid flows from the inner tube into the heat dissipation fins, it is guided by the lower part of the head end of the heat dissipation fins inserted into the inner tube.

[0078] The liquid flows towards the tail end of the heat dissipation fin tube, thereby allowing the liquid to flow as fully as possible within the heat dissipation fin tube, increasing the time the liquid flows within the heat dissipation fin tube, and thus increasing the heat dissipation time.

[0079] When the liquid flows from the outer tube into the heat dissipation fins, the baffle strip and the inner wall of the outer tube form a guiding structure. As the liquid flows from the outer tube into the heat dissipation fins, it forms a guide, forcing the liquid to flow as far as possible towards the tail end of the heat dissipation fins, increasing the time the liquid flows in the heat dissipation fins and increasing the heat dissipation time.

[0080] Therefore, regardless of whether the first liquid pipe or the second liquid pipe is used as the liquid input pipe, it can be ensured that the liquid flowing into the heat dissipation fin can flow to the tail end of the heat dissipation fin to the maximum extent, increasing the liquid's flow time in the heat dissipation fin and thus dissipating more heat.

[0081] To prevent liquid from flowing directly from the lower part of the head end of the heat dissipation fins to the upper part of the head end of the heat dissipation fins instead of flowing to the tail end of the heat dissipation fins, a flow-blocking strip is installed.

[0082] As shown in Figures 7 and 9, in this embodiment, the current sharing unit includes:

[0083] A flow-limiting strip is installed on the upper surface of the flow-blocking strip, with its side surface fitting against the front inner surface of the outer tube, controlling the flow area between the outer C-shaped groove and the notch at the head end of each heat dissipation fin.

[0084] The current sharing unit further includes:

[0085] A flow equalization strip is installed inside the outer tube and fixed to the outer surface of the inner tube. The flow equalization strip is located between the end of the first liquid tube and the upper part of the head end of each heat dissipation fin tube, controlling the flow area between the end of the first liquid tube and the upper part of the head end of each heat dissipation fin tube.

[0086] The flow-limiting strip and the flow-equalizing strip can limit the overall flow of liquid, thereby preventing the liquid from mainly flowing through the heat dissipation fins near the connection between the first liquid pipe and the outer pipe or the connection between the second liquid pipe and the inner pipe. This ensures that the liquid velocity and flow rate in all heat dissipation fins are roughly the same, increasing the overall heat dissipation efficiency.

[0087] In this embodiment, the bottom of the inner C-shaped groove is flush with the bottom of the outer C-shaped groove; the projection of the lower surface of the heat dissipation fin is located inside the side wall of the outer C-shaped groove; the lower end face of the head of the heat dissipation fin is seamlessly fixed to the bottom of the inner C-shaped groove and the bottom of the outer C-shaped groove.

[0088] This design allows for better processing of the inner tube, outer tube, and heat dissipation fins, reducing processing difficulty and assembly production difficulty.

[0089] In this embodiment, the upper notch at the head end of the heat dissipation fin is groove-shaped; the upper end face of the head of the heat dissipation fin is seamlessly fixed to the bottom of the outer C-shaped groove.

[0090] The groove shape can increase the connection area between the upper part of the heat dissipation fin and the outer tube, thereby increasing the connection strength between the heat dissipation fin and the outer tube.

[0091] In this embodiment, the upper end face of the head of the heat dissipation fin extends beyond the upper outer surface of the outer tube;

[0092] The outer surface of the outer tube is provided with a sealing strip to seal the end face of all heat dissipation fins that extend beyond the outer surface of the outer tube.

[0093] This design adds another flow path to the liquid flow path between the outer tube and the heat dissipation fins, namely, the connecting channel between the upper part of the outer tube and the upper part of the heat dissipation fins. In this way, some of the liquid flowing between the inner and outer tubes needs to flow through a larger C-shaped path, which increases the flow area and the liquid flow path and time.

[0094] In addition, sealing strips can be used to increase the structural strength of the connection between the heat dissipation fins and the outer tube.

[0095] In this embodiment, the junctions of the first liquid pipe and the second liquid pipe with the outer pipe are at the same horizontal height on the outer pipe;

[0096] At least one protrusion is provided on the lower outer surface of the outer tube.

[0097] The protrusions can be used as positioning protrusions to facilitate the installation of this device.

[0098] The water circulation and heat dissipation device for glass fiber production in this embodiment is used as follows: This invention can use either a first liquid pipe as the liquid input pipe and a second liquid pipe as the liquid output pipe, or vice versa. The following explanation uses the second liquid pipe as the liquid input pipe and the first liquid pipe as the liquid output pipe to illustrate the product principle.

[0099] The base absorbs the heat generated during the production of glass fiber and transfers the heat to the liquid. The liquid circulates through the first and second liquid pipes via a water pump. The structure of this part is basically the same as that of a desktop computer's water cooling radiator.

[0100] High-temperature liquid flows from the second liquid pipe into the inner pipe under the action of the water pump. Then it flows from the lower part of the head end of the heat dissipation fin to the tail end of the heat dissipation fin for heat dissipation. Then, under the pressure of the water pump, it flows to the upper part of the head end of the heat dissipation fin, passes through the outer C-shaped groove of the outer pipe and flows into the outer pipe. Finally, it flows into the base through the second liquid pipe and circulates there.

[0101] As the liquid flows from the upper part of the head end of the heat dissipation fins into the outer tube through the outer C-shaped groove, the cooled liquid flowing out of each heat dissipation fin is restricted by the flow-blocking and flow-limiting strips, so that the flow velocity and flow rate of the cooled liquid flowing out of each heat dissipation fin are not much different. Then it flows into the outer tube. When it flows into the first liquid tube in the outer tube, it is blocked by the flow equalization strip, which increases the flow resistance of individual heat dissipation fins with larger flow velocities and flow rates.

[0102] Under the combined action of the baffle, flow limiting, and flow equalization strips, the flow rate and velocity of the high-temperature liquid flowing from the inner tube into each heat dissipation fin are approximately the same.

[0103] The use of products that use the first liquid pipe as the liquid input pipe and the second liquid pipe as the liquid output pipe is largely the same as described above, so it will not be explained again.

[0104] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
