Description

Technical Field

[0001] This utility model relates to the field of cooling technology, specifically a Vicat softening and cooling device. Background Technology

[0002] Currently, the Vicat softening temperature test suffers from the problem of slow cooling of the heat transfer medium, which affects the test speed. During the Vicat softening temperature test, the temperature needs to be gradually increased during the test. After the test, the temperature of the heat transfer medium reaches as high as 80°C. After the test, it needs to be cooled down by 50°C before the next set of tests can be carried out. Because there are many heat transfer media and the heating bath is an insulated structure, the natural cooling rate is extremely slow. Developing a cooling device that can accelerate the cooling of the heat transfer medium and reduce the test interval is of practical significance. However, the existing Vicat softening cooling device still has certain defects in use.

[0003] A cooling device for a heat distortion Vicat softening point temperature tester, as proposed in application number CN202321226804.4, includes a tester body. A cooling box is disposed inside the tester body. A base is fixedly installed at the bottom of the tester body. The base has a hollow internal structure. A liquid storage tank is fixedly installed on the inner bottom wall of the base. A water pump is fixedly installed on one side surface of the liquid storage tank. A delivery pipe and a first telescopic pipe are fixedly installed at the inlet and outlet ends of the water pump, respectively. The other end of the first telescopic pipe extends into the interior of the tester body and... Connected to one side of the cooling tank, in actual use, the coolant in the storage tank is pumped into the cooling tank by a water pump. The coolant can thoroughly cool down the test oil tank. However, the coolant, after absorbing heat and becoming hot, re-enters the storage tank. After absorbing heat from the test oil tank, the coolant easily accumulates high temperature, and its cooling capacity gradually decreases with the extension of operating time. It is difficult to maintain a continuous and stable cooling effect by relying solely on the fan for heat dissipation. Furthermore, after the test oil tank descends, it comes into contact with the coolant inside the cooling tank, so when it rises, the coolant sticks to the surface of the cooling tank, affecting the operating environment.

[0004] Therefore, we propose a Vicat softening and cooling device to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a Vicat softening and cooling device to solve the problems mentioned in the background art, such as the heat-absorbing coolant easily accumulating temperature when returning to the storage tank, the difficulty in stabilizing the temperature due to fan cooling alone, and the coolant sticking to the cooling tank when the test oil tank rises, affecting the environment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a Vicat softening and cooling device, comprising a heating bath and a cooling tank, wherein the heating bath is surrounded by a cooling tank, a heat-conducting pipe is installed inside the cooling tank, a micro pump is fixedly installed at the liquid outlet end of the heat-conducting pipe, a water outlet pipe is fixedly connected to the water outlet end of the micro pump, a liquid storage tank is fixedly installed at the water outlet end of the water outlet pipe, a water inlet pipe is fixedly connected to the liquid inlet end of the heat-conducting pipe, the liquid inlet end of the water inlet pipe is connected to the liquid storage tank, and a liquid exchange port is installed at the bottom front side of the cooling tank;

[0007] An active heat dissipation mechanism is connected to the bottom of the liquid storage tank;

[0008] A driven mixing mechanism is installed at the bottom of the cooling tank;

[0009] The active heat dissipation mechanism is connected to the liquid storage tank by a plug-in positioning mechanism.

[0010] Preferably, the active heat dissipation mechanism includes a semiconductor cooling chip fixedly attached to the bottom surface of the liquid storage tank, wherein heat dissipation fins are fixedly attached to the bottom surface of the semiconductor cooling chip, and heat dissipation fan groups are symmetrically distributed at the bottom of the heat dissipation fins.

[0011] The above-mentioned structure design allows for efficient cooling of the accumulator tank directly through a semiconductor cooling chip. Combined with heat dissipation fins to increase the heat dissipation area, and a cooling fan group to accelerate airflow and remove heat, an active and efficient heat dissipation circulation system is formed. This system can quickly reduce the temperature of the coolant in the accumulator tank, ensuring the cooling effect of the cooling medium. It also facilitates better heat dissipation of the cooling medium to the heat-conducting medium inside the cooling tank, thereby improving the cooling efficiency of the heat-conducting medium to the heating bath.

[0012] The cooling tank can wrap around the heating bath without damaging its insulation structure, thus improving its performance.

[0013] Preferably, the driven mixing mechanism includes a transmission rod fixedly connected to the top of the heat sink fins. The transmission rod is connected through the semiconductor cooling chip, the heat sink fins, and the liquid storage tank. A sealed bearing is fitted around the top outer ring of the transmission rod, and the sealed bearing is connected to the bottom of the cooling tank.

[0014] Preferably, the driven mixing mechanism further includes a stirring blade fixedly sleeved on the top of the transmission rod. When the stirring blade rotates, it mixes and stirs the heat-conducting medium inside the cooling tank to improve the uniformity of heat conduction.

[0015] The above-described structure utilizes a transmission rod to transfer power from the active cooling mechanism to the cooling tank. The sealed bearings ensure smooth rotation of the transmission rod and effectively prevent leakage of the heat transfer medium within the cooling tank. The stirring blades, driven by the transmission rod, rotate to thoroughly mix the heat transfer medium within the cooling tank, preventing uneven local temperatures and ensuring that the heat transfer medium can uniformly absorb heat from the heating bath, significantly improving heat transfer uniformity and the stability of the cooling effect.

[0016] Preferably, the plug-in positioning mechanism includes plug-in plates symmetrically installed on the outer ring of the cooling fan assembly, and the top of the plug-in plates has a locking groove.

[0017] Preferably, the insertion positioning mechanism further includes limiting seats symmetrically installed on the front and rear surfaces of the liquid storage tank. A locking rod slides through the interior of the limiting seat. A control plate is fixedly installed at the end of the locking rod away from the limiting seat. A telescopic spring is sleeved on the outer ring of the locking rod between the control plate and the limiting seat. The control plate and the locking rod form a telescopic structure with the limiting seat through the telescopic spring. The locking rod is movably engaged with the locking groove.

[0018] The above-mentioned structure allows for the initial positioning of the active cooling mechanism and the liquid storage tank through the cooperation of the plug-in plate and the limiting seat. Under the elastic force of the telescopic spring, the locking rod can be tightly locked into the locking groove, completing the firm connection between the two. This plug-in positioning structure not only makes installation and disassembly convenient and quick, but also facilitates the maintenance and replacement of the active cooling mechanism in the later stages, thus improving the convenience of maintenance.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the Vicat softening and cooling device;

[0020] 1. The design of the cooling tank surrounding the heating bath achieves efficient enveloping cooling without damaging the insulation structure of the heating bath. The active heat dissipation mechanism forms an efficient heat dissipation cycle through the synergistic action of semiconductor cooling chips, heat dissipation fins and cooling fan assembly, ensuring that the cooling medium maintains a good cooling effect. The passive mixing mechanism stirs the heat-conducting medium in the cooling tank with the help of stirring fan blades to avoid uneven local temperature and make the heat-conducting medium absorb heat from the heating bath evenly, further ensuring the stability of the cooling effect.

[0021] 2. The plug-in positioning mechanism achieves rapid disassembly and assembly of the active heat dissipation mechanism and the liquid storage tank by initially positioning the plug-in plate and the limit seat, and cooperating with the telescopic spring to drive the locking rod and the locking groove to lock firmly. This greatly simplifies the later maintenance and replacement process, improves the ease of use and maintenance efficiency of the device, and extends the overall service life of the equipment.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a Vicat softening and cooling device, including a heating bath 1 and a cooling tank 2. The heating bath 1 is surrounded by a cooling tank 2. A heat-conducting pipe 3 is installed inside the cooling tank 2. A micro pump 4 is fixedly installed at the liquid outlet end of the heat-conducting pipe 3. A water outlet pipe 5 is fixedly connected to the water outlet end of the micro pump 4. A liquid storage tank 6 is fixedly installed at the water outlet end of the water outlet pipe 5. A water inlet pipe 7 is fixedly connected to the liquid inlet end of the heat-conducting pipe 3. The liquid inlet end of the water inlet pipe 7 is connected to the liquid storage tank 6. A liquid exchange port 8 is installed at the bottom front side of the cooling tank 2.

[0031] In the above-described structure, the heating bath 1 serves as the core heating component of the Vicat softener. The cooling tank 2 surrounding it forms a surrounding cooling space. The cooling tank 2 is filled with a heat-conducting medium, which can directly absorb the heat transferred from the heating bath 1. Power is provided by the micro pump 4, which drives the cooling medium in the storage tank 6 to enter the heat-conducting pipe 3 through the water inlet pipe 7. The heat-conducting pipe 3 is installed inside the cooling tank 2 and is in full contact with the heat-conducting medium in the cooling tank 2. Through heat exchange, it absorbs the heat in the heat-conducting medium, thereby reducing the temperature of the heat-conducting medium in the cooling tank 2 and enhancing its cooling effect on the heating bath 1.

[0032] After absorbing heat, the cooling medium flows back to the storage tank 6 through the outlet pipe 5 under the action of the micro pump 4, completing one cooling cycle. The active heat dissipation mechanism connected to the storage tank 6 will cool down the high-temperature cooling medium that flows back, ensuring that the cooling medium re-entering the cycle maintains a low temperature and ensuring continuous and effective cooling capacity. In addition, the liquid exchange port 8 at the bottom front of the cooling tank 2 can be used to periodically replace the heat transfer medium inside the cooling tank 2, avoiding a decrease in thermal conductivity after long-term use and maintaining a stable cooling effect of the device.

[0033] An active heat dissipation mechanism is connected to the bottom of the liquid storage tank 6. The active heat dissipation mechanism includes a semiconductor cooling chip 9 fixedly attached to the bottom surface of the liquid storage tank 6. Heat dissipation fins 10 are fixedly attached to the bottom surface of the semiconductor cooling chip 9. Heat dissipation fan groups 11 are symmetrically distributed at the bottom of the heat dissipation fins 10.

[0034] The above-mentioned structure design, through the close contact between the semiconductor cooling chip 9 and the bottom surface of the liquid storage tank 6, can directly and efficiently absorb the heat of the cooling medium in the liquid storage tank 6. It utilizes the thermoelectric effect of the semiconductor cooling chip 9 to achieve rapid cooling, quickly reduce the temperature of the cooling medium, and provide a continuous low-temperature cooling source for the cooling circulation system. At the same time, the heat dissipation fins 10 fixed on the bottom surface of the semiconductor cooling chip 9 greatly increase the heat dissipation area, which can quickly conduct and diffuse the excess heat generated by the semiconductor cooling chip 9 during operation, and prevent it from reducing its cooling efficiency due to heat accumulation.

[0035] Meanwhile, the symmetrically distributed cooling fan group 11 at the bottom of the heat dissipation fins 10 further enhances the heat dissipation effect of the heat dissipation fins 10 by accelerating airflow, and promptly dissipates heat, forming a highly efficient synergistic mechanism of "cooling, heat dissipation, and enhanced heat dissipation". This ensures that the cooling medium in the liquid storage tank 6 always maintains good cooling capacity, thereby significantly improving the cooling efficiency and stability of the entire device for the heating bath 1, and ensuring the cooling effect of the heat transfer medium during the Vicat softening test.

[0036] A driven mixing mechanism is installed at the bottom of the cooling tank 2. The driven mixing mechanism includes a transmission rod 12 fixedly connected to the top of the heat dissipation fins 10. The transmission rod 12 is connected through the semiconductor cooling chip 9, the heat dissipation fins 10 and the liquid storage tank 6. A sealed bearing 13 is sleeved on the top outer ring of the transmission rod 12. The sealed bearing 13 is connected to the bottom of the cooling tank 2. The driven mixing mechanism also includes a stirring fan blade 14 fixedly sleeved on the top of the transmission rod 12. When the stirring fan blade 14 rotates, it mixes and stirs the heat conduction medium inside the cooling tank 2 to improve the heat conduction uniformity.

[0037] The above-described structure, when the active cooling mechanism is running, the transmission rod 12 passes through the semiconductor cooling chip 9, the heat dissipation fins 10 and the liquid storage tank 6, and in conjunction with the connection with the cooling fan assembly 11, can transmit the power of the cooling fan assembly 11 upward to the bottom of the cooling tank 2. The sealed bearing 13 sleeved on the outer ring of the top of the transmission rod 12 is connected to the bottom of the cooling tank 2, which not only provides stable rotational support for the transmission rod 12, ensuring its smooth rotation without being obstructed by the bottom structure of the cooling tank 2, but also effectively isolates the heat-conducting medium inside the cooling tank 2 through the sealing characteristics of the bearing, preventing it from leaking along the connection gap between the transmission rod 12 and the cooling tank 2, thus ensuring the sealing and stable medium capacity of the cooling tank 2.

[0038] Through this structure, the power of the cooling fan assembly 11 is efficiently converted into the rotational motion of the transmission rod 12, which provides the driving force for the subsequent mixing of the heat-conducting medium in the cooling tank 2 by the stirring fan blades 14, thus realizing the coordinated operation of heat dissipation and medium mixing.

[0039] An insertion positioning mechanism is connected between the active cooling mechanism and the liquid storage tank 6. The insertion positioning mechanism includes an insertion plate 15 symmetrically installed on the outer ring of the cooling fan assembly 11. The top of the insertion plate 15 is provided with a locking groove 16. The insertion positioning mechanism also includes a limiting seat 17 symmetrically installed on the front and rear surfaces of the liquid storage tank 6. A locking rod 18 slides through the inside of the limiting seat 17. A control plate 19 is fixedly installed at the end of the locking rod 18 away from the limiting seat 17. A telescopic spring 20 is sleeved on the outer ring of the locking rod 18 between the control plate 19 and the limiting seat 17. The control plate 19 and the locking rod 18 form a telescopic structure with the limiting seat 17 through the telescopic spring 20. The locking rod 18 is movably engaged with the locking groove 16.

[0040] The above-described structure design allows for easy installation of the active cooling mechanism. Since the connector plates 15 are symmetrically installed on the outer ring of the cooling fan assembly 11, and the limiting seats 17 are correspondingly distributed on both sides of the reservoir 6, installation is simple: just align the connector plates 15 on the outer ring of the cooling fan assembly 11 with the gaps between the limiting seats 17 on both sides of the reservoir 6. This quickly aligns the active cooling mechanism with the reservoir 6, preventing misalignment or displacement during installation and laying the foundation for subsequent fixing. Before inserting the connector plates 15, the locking rod 18 is pulled outwards by the control board 19, causing the locking rod 18 to move away from the reservoir. When the limiting seat 17 slides in the direction, the telescopic spring 20 on the outer ring of the locking rod 18 is compressed due to the displacement of the control plate 19, storing elastic potential energy. When the plug plate 15 is inserted into the preset position, and the locking groove 16 at its top is just aligned with the locking rod 18, the telescopic spring 20 releases elastic potential energy, pushing the control plate 19 to drive the locking rod 18 to slide into the limiting seat 17, so that the locking rod 18 is accurately locked into the locking groove 16. The plug plate 15 and the limiting seat 17 are firmly fixed by the mechanical locking structure, thereby realizing the stable connection between the active heat dissipation mechanism and the liquid storage tank 6.

[0041] When disassembly and maintenance are required, simply pull the control plate 19 away from the limit seat 17. The control plate 19 will cause the locking rod 18 to slide synchronously, disengaging the locking rod 18 from the locking groove 16. At the same time, the telescopic spring 20 will be compressed again, keeping the control plate 19 in the pulled state. This allows the cooling fan assembly 11, along with the plug plate 15, to be pulled out from the gap of the limit seat 17, completing the disassembly and separation of the cooling fan assembly 11. This greatly improves the convenience of later maintenance or replacement of the active cooling mechanism.

[0042] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
