[0001] The invention belongs to the technical field of cooling devices, and in particular relates to a water cooling device. Background Art

[0002] With the rapid development of industrial production, the heating temperature of materials in some fields is getting higher and higher. After heating, in order to put the materials into production quickly, water cooling equipment is needed to quickly cool the materials to improve production efficiency and shorten cooling time.

[0003] Traditional cooling equipment can be roughly divided into two types: air cooling and water cooling. Among them, water cooling is widely used due to its advantages such as high efficiency and fast speed.

[0004] To save time, existing water cooling equipment typically cools materials during transport. However, due to the high flow rate of materials, especially liquid materials, during transport, the contact frequency and duration between the cooling water and the liquid material are too low, resulting in poor cooling performance.

[0009] Furthermore, a snap-in groove is provided on one side wall of the water cooling box close to the second water cooling unit, and the snap-in groove is an arc-shaped structure, and the outer wall of the transmission pipe body is attached to the inner wall of the snap-in groove; several groups of heat conduction plates are installed on the inner wall of the side of the water cooling chamber away from the second water cooling unit.

[0010] Furthermore, a group of heat absorbing mechanisms are fixedly installed on each group of the heat conducting plates, and the other end of the heat absorbing mechanism is fixedly installed on a side wall of the water cooling chamber close to the second water cooling unit; the heat absorbing mechanism is a fan ring structure.

[0011] Furthermore, a first liquid supply pipe is connected to a side wall of the water-cooling chamber close to the second water-cooling unit, and a first boosting valve is provided on the first liquid supply pipe. A first liquid inlet pipe is connected to a side of the water-cooling chamber away from the first liquid supply pipe, and the other ends of the first liquid supply pipe and the first liquid inlet pipe are both connected to the inner cavity of the transmission unit.

[0012] Furthermore, the heat absorption mechanism includes a heat-conducting frame and several groups of heat-absorbing tubes; the two ends of the heat-conducting frame are respectively fixedly mounted on the heat-conducting plate and the inner wall of the water-cooling chamber on one side close to the second water-cooling unit, and the heat-conducting frame is a fan-shaped ring structure; several groups of heat-absorbing tubes are mounted on the heat-conducting frame at equal intervals.

[0013] Furthermore, a group of cooling fans are fixedly installed on each group of the heat conducting plates, and the cooling fan outlets are located outside the water cooling box.

[0014] Furthermore, the water cooling device also includes two groups of connection units, and the two groups of connection units are respectively sleeved on the openings at both ends of the transmission pipe body.

[0015] Furthermore, the connection unit includes a connector and a sleeve; one end of the sleeve is sleeved on an opening at one end of the transmission pipe body, and a sealing gasket is fixedly installed on the inner wall of the sleeve; the other end of the sleeve is fixedly installed with a connector.

[0017] The beneficial effects of the present invention are:

[0018] 1. During the transmission process, liquid materials first enter the liquid infusion pipe through the connecting unit. Then, cooling water from the water-cooling chamber and the inner cavity of the second water-cooling unit is injected into the outer cooling cavity and the inner cooling pipe, respectively. This cools the liquid materials simultaneously from both inside and outside the liquid infusion pipe, improving cooling quality. Furthermore, the first and second boost valves increase the cooling water flow rate, allowing the cooling water to flow quickly toward the first and second liquid inlet pipes, accelerating the cooling water circulation rate and increasing the frequency of contact between the cooling water and the liquid infusion pipe, thereby enhancing the cooling effect.

[0019] 2. The first and second spiral guide plates are fixed to the liquid inlet pipe and the guide plate mounting rod, respectively, in a spiral pattern. After entering the outer cooling cavity and inner cooling pipe, the cooling water flows in a spiral pattern toward the first or second liquid inlet pipe. This maintains a high cooling water flow rate and ensures more even contact between the cooling water and the inner and outer walls of the liquid inlet pipe, thereby improving cooling quality.

[0020] 3. After returning to the water-cooling chamber, the cooling water will enter several groups of evenly spaced heat-absorbing tubes, absorbing the heat from the cooling water. The heat is then transferred to the heat-conducting plate through the heat-conducting frame and finally exhausted through the cooling fan. The cooled cooling water will continue to move toward the first liquid delivery pipe, thus meeting the requirements of self-circulation and self-cooling of the cooling water, ensuring the smoothness of the water cooling process. Moreover, during the continuous circulation of the cooling water, the cooling effect will not be affected by poor heat dissipation.

[0021] 4. Through the clamping relationship between the inverted clamp head and the inverted clamping groove, as well as the threaded connection relationship between the threaded ring body and the external threaded sleeve, the connector can be fixed to the end of the transmission pipe body, making it easy to connect the transmission pipe body to the external pipeline. There is no need to use screws or other easily oxidized structures for fixing, which not only improves the fixing effect, but also makes disassembly and assembly quick and time-saving, and facilitates later maintenance.

DETAILED DESCRIPTION

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0038] The embodiment of the present invention provides a water cooling device, including a water cooling module, a transmission unit 400 and two sets of connection units 500. For example, Figure 1 As shown, the transmission unit 400 is located in the water-cooling module, and both ends of the transmission unit 400 extend through the outside of the water-cooling module. The transmission unit 400 is used to transmit liquid materials.

[0039] The two sets of connecting units 500 are fixedly mounted at both ends of the transmission unit 400, and the cavities of the two sets of connecting units 500 are connected to the cavity of the transmission unit 400. The connecting units 500 are used to connect the transmission unit 400 to an external feeding pipe.

[0040] The water-cooling module includes a first water-cooling unit 100 and a second water-cooling unit 200. The second water-cooling unit 200 has the same structure as the first water-cooling unit 100 and is symmetrically arranged with the first water-cooling unit 100 about the centerline of the transmission unit 400. The first water-cooling unit 100 and the second water-cooling unit 200 are used to cool the cooling water, thereby enabling continuous circulation of the cooling water.

[0041] The inner cavities of the first water cooling unit 100 and the second water cooling unit 200 are both communicated with the inner cavity of the transmission unit 400 .

[0042] A plurality of cooling fans 300 are arranged at equal intervals on the two side walls of the first water cooling unit 100 and the second water cooling unit 200 that are away from each other. The cooling fans 300 are used to dissipate heat in the cooling water.

[0043] The first water cooling unit 100 includes a water cooling box 130. For example, Figure 2 and Figure 3 As shown, a snap-in slot 131 is defined on a side wall of the water-cooling box 130 near the second water-cooling unit 200. This snap-in slot 131 is an arc-shaped structure, and the outer shell of the transmission unit 400 fits snugly within this snap-in slot 131. A water-cooling chamber 140 is defined within the water-cooling box 130. Several sets of heat-conducting plates 150 are fixedly mounted on the inner wall of the water-cooling chamber 140 away from the second water-cooling unit 200. The number of these heat-conducting plates 150 is the same as the number of cooling fans 300 installed on the water-cooling box 130, and one side wall of each set of heat-conducting plates 150 fits snugly onto a corresponding set of cooling fans 300. Each set of heat-conducting plates 150 is fixedly mounted on a heat-absorbing mechanism 160, the other end of which is fixedly mounted on a side wall of the water-cooling chamber 140 near the second water-cooling unit 200. Each heat-absorbing mechanism 160 has a fan-shaped ring structure. A first liquid supply pipe 110 is connected to a side wall of the water-cooling chamber 140 near the second water-cooling unit 200. A first pressure-boosting valve 111 is provided on the first liquid supply pipe 110. The other end of the first liquid supply pipe 110 is connected to the inner cavity of the transmission unit 400. A first liquid inlet pipe 120 is connected to the side of the water-cooling chamber 140 away from the first liquid supply pipe 110. The other end of the first liquid inlet pipe 120 is connected to the inner cavity of the transmission unit 400.

[0044] The heat absorption mechanism 160 includes a heat conducting frame 161 and a plurality of heat absorption tubes 162. For example, Figure 4As shown, the two ends of the heat conducting frame 161 are fixedly mounted on the heat conducting plate 150 and the inner wall of the water cooling chamber 140 near the second water cooling unit 200. The heat conducting frame 161 has a fan-shaped structure. Several groups of heat absorbing tubes 162 are evenly spaced and mounted on the heat conducting frame 161.

[0045] For example, Figure 3 As shown, the inner cavity of the second water-cooling unit 200 is connected to a second liquid supply pipe 210, the other end of which is connected to the inner cavity of the transmission unit 400. A second boosting valve 211 is provided on the second liquid supply pipe 210. The inner cavity of the second water-cooling unit 200 on the side away from the second liquid supply pipe 210 is connected to a second liquid inlet pipe 220, the other end of which is connected to the inner cavity of the transmission unit 400.

[0046] During the transfer of liquid material, cooling water from the water-cooling chamber 140 and the inner cavity of the second water-cooling unit 200 is simultaneously transported to the transfer unit 400 via the first liquid delivery pipe 110 and the second liquid delivery pipe 210, thereby cooling the liquid material being transferred. Furthermore, during the cooling process, the cooling water flows within the housing of the transfer unit 400 toward the first liquid inlet pipe 120 and the second liquid inlet pipe 220, ultimately passing through the first liquid inlet pipe 120 and the second liquid inlet pipe 220 and entering the water-cooling chamber 140 and the second water-cooling unit 200, respectively.

[0047] After returning to the water-cooling chamber 140, the cooling water passes through several equally spaced groups of heat-absorbing tubes 162, absorbing the heat from the cooling water. The heat is then transferred to the heat-conducting plate 150 via the heat-conducting frame 161, and ultimately exhausted through the cooling fan 300. The cooled cooling water continues to flow toward the first liquid delivery pipe 110, thus satisfying the requirement for self-circulation and self-cooling of the cooling water, ensuring smooth water cooling. Furthermore, during the continuous circulation of the cooling water, the cooling effect will not be affected by poor heat dissipation.

[0048] The transmission unit 400 includes a transmission tube body 410 and a guide plate mounting rod 450. For example, Figure 5 and Figure 6As shown, the ends of the transmission tube body 410 are respectively attached to the clamping groove 131 and the outer wall of the second water-cooling unit 200. An external cooling cavity 420 is defined within the transmission tube body 410. A first liquid baffle 421 is provided at each end of the external cooling cavity 420, and the external cooling cavity 420 is connected to the first liquid delivery pipe 110 and the first liquid inlet pipe 120, respectively. A liquid infusion tube 430 is provided within the external cooling cavity 420, and the ends of the liquid infusion tube 430 are respectively connected to the inner lumens of the two sets of the connecting units 500. A first spiral guide plate 422 is mounted on the liquid infusion tube 430. The first spiral guide plate 422 is spirally wound around the outer wall of the liquid infusion tube 430, and the side wall of the first spiral guide plate 422 away from the liquid infusion tube 430 is attached to the inner wall of the transmission tube body 410. An inner cooling tube 440 is disposed within the liquid delivery tube 430 and is in communication with the second liquid delivery tube 210 and the second liquid inlet tube 220, respectively. A set of second liquid baffles 441 are disposed at each end of the inner cooling tube 440. The deflector mounting rod 450 is positioned within the inner cooling tube 440 and fixedly mounted at both ends to the two sets of second liquid baffles 441. A second spiral deflector 460 is mounted on the deflector mounting rod 450. The second spiral deflector 460 is spirally wound around the deflector mounting rod 450, with the sidewall of the second spiral deflector 460 facing away from the deflector mounting rod 450 abutting against the inner wall of the inner cooling tube 440.

[0049] During the transfer process, the liquid material first enters the liquid infusion pipe 430 through the connecting unit 500. The cooling water in the water-cooling chamber 140 and the inner cavity of the second water-cooling unit 200 is then injected into the outer cooling chamber 420 and the inner cooling pipe 440, respectively. This cools the liquid material simultaneously from both the inside and outside of the liquid infusion pipe 430, improving the cooling quality. Furthermore, the cooling water flow rate is increased by the first and second booster valves 111 and 211, allowing the cooling water to flow quickly toward the first and second liquid inlet pipes 120 and 220. This speeds up the cooling water's circulation and increases the frequency of contact between the cooling water and the liquid infusion pipe 430, thereby enhancing the cooling effect.

[0050] The first spiral guide plate 422 and the second spiral guide plate 460 are respectively fixed in a spiral manner to the liquid delivery tube 430 and the guide plate mounting rod 450. After entering the outer cooling cavity 420 and the inner cooling tube 440, the cooling water flows in a spiral manner toward the first liquid inlet tube 120 or the second liquid inlet tube 220. This maintains a high flow rate of the cooling water and also ensures more uniform contact between the cooling water and the inner and outer walls of the liquid delivery tube 430, thereby improving cooling quality.

[0051] For example, Figure 7As shown, the transmission tube body 410 is provided with a plurality of groups of chute grooves 470 arranged in a circular array at both ends. Each group of chute grooves 470 has a plurality of groups of evenly spaced inverted retaining grooves 471 arranged on the inner wall of one side. The angle between the inverted retaining grooves 471 and the central axis of the transmission tube body 410 is less than 90°. The transmission tube body 410 is provided with an externally threaded sleeve 480, and the connecting unit 500 is fixedly connected to the transmission tube body 410 via the inverted retaining grooves 471 and the externally threaded sleeve 480.

[0052] When pipes need to be docked, first, each set of the connecting mechanisms of the connecting unit 500 is respectively engaged in each set of the sliding grooves 470, and then the connecting unit 500 is pushed inward so that the connecting mechanisms can move to a position flush with the inverted locking grooves 471. Then, the connecting unit 500 is rotated so that its connecting mechanisms can be engaged in the inverted locking grooves 471. There is no need to use screws or other easily oxidized structures for fixing, and disassembly and assembly are quick and time-saving, which facilitates later maintenance.

[0053] The connecting unit 500 includes a connecting head 510 and a sleeve 520. For example, Figure 8 、 Figure 9 and Figure 10 As shown, one end of the sleeve 520 is sleeved onto an opening at one end of the transmission tube body 410, and a plurality of groups of inverted clamps 550 are arranged in a circular array on the inner wall of the sleeve 520. The number of inverted clamps 550 is the same as the number of inverted clamping grooves 471, and each group of inverted clamps 550 can be movably clamped into a corresponding group of inverted clamping grooves 471. A sealing gasket 521 is fixedly mounted on the inner wall of the sleeve 520. A connector 510 is fixedly mounted on the other end of the sleeve 520. An internal connecting tube 530 is disposed within the connector 510, and the central axis of the internal connecting tube 530 coincides with that of the connector 510. One end of the internal connecting tube 530 is connected to the infusion tube 430, and the other end has a connecting port 540, which is equipped with a filter screen 541. A ring 522 is mounted on the end of the sleeve 520 away from the connector 510 to prevent the ring from falling off. A threaded ring 560 is sleeved onto the outer wall of the sleeve 520. The inner diameter of the threaded ring 560 is smaller than the outer diameters of the anti-slip ring 522 and the connector 510. The threaded ring 560 can be threaded onto the externally threaded sleeve 480. A waterproof gasket 570 is provided at the junction of the internal connecting tube 530 and the transmission tube body 410.

[0054] The threaded ring 560 includes a threaded ring body 561. For example, Figure 11 and Figure 12As shown, the threaded ring body 561 is movably mounted on the outer wall of the transmission tube 410, and the inner diameter of the threaded ring body 561 is larger than the outer diameter of the anti-slip ring 522. An internal threaded opening 563 is formed on the inner surface of the threaded ring body 561, through which the threaded ring body 561 can be threadedly connected to the externally threaded sleeve 480. An anti-slip ring 562 is provided at one end of the threaded ring body 561 near the connector 510. The inner diameter of the anti-slip ring 562 is smaller than the outer diameters of the anti-slip ring 522 and the connector 510.

[0055] To connect the transmission tube 410 to an external pipeline, first, each set of inverted clamps 550 is snapped into place within each set of chute 470. Then, the connector 510 is pushed inward until the inverted clamps 550 are flush with the inverted clamping grooves 471. The connecting unit 500 is then rotated so that the inverted clamps 550 are snapped into place within the inverted clamping grooves 471. The threaded ring body 561 is then threaded onto the externally threaded sleeve 480. This eliminates the need for screws or other easily oxidized structures, improving the fixing effect and making assembly and disassembly quick and time-saving, facilitating subsequent maintenance.

[0056] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
