Description

Technical Field

[0001] The utility model relates to the technical field of temperature control devices, in particular to a circulating water temperature control device. Background Art

[0002] In industrial production, circulating water is mainly used to cool production equipment. At present, when circulating water is cooled, a temperature control device is needed to control the temperature of the circulating water.

[0003] For example, the patent with announcement number CN219955835U discloses a heat dissipation device for circulating water in a non-woven meltblown workshop. Although the heat dissipation device delivers cold air to the annular tube through a blowing mechanism, so that the cold air is blown into the circulating water of the heat dissipation body through the air outlet nozzle on the annular tube and forms bubbles, the bubbles absorb the heat in the circulating water and float up to the water surface and burst, thereby allowing the heat of the circulating water to be discharged from the exhaust pipe along with the flow of gas, thereby improving the heat dissipation and cooling efficiency of the circulating water in the heat dissipation body; however, when the heat dissipation device is actually used, the heat dissipation of the circulating water in the heat dissipation body is dissipated by arranging heat sinks on the outer side of the heat dissipation body. Since it only relies on natural convection between the heat sinks and the air to dissipate heat, the heat dissipation effect of this heat dissipation method is limited, so it needs to be improved.

It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0028] The following is combined with Figure 1-Figure 5 This embodiment is described in further detail.

[0029] Combine Figure 1-Figure 5 As shown, a circulating water temperature control device in this embodiment includes a cooling tank 10 and a water storage tank 20. The water storage tank 20 is arranged in the cooling tank 10. A cooling cavity 700 is formed between the water storage tank 20 and the cooling tank 10. A water inlet pipe 100 is provided on the outer side of the cooling tank 10 and at the bottom. The water inlet pipe 100 passes through the cooling cavity 700 and communicates with the water storage tank 20. A water outlet pipe 110 is provided on the outer side of the cooling tank 10 and at the top. The water outlet pipe 110 passes through the cooling cavity 700 and communicates with the water storage tank 20. The cooling cavity A heat dissipation fin 130 is provided in 700 along its radial direction, and a side wall of the heat dissipation fin 130 is connected to the outer wall of the water storage tank 20. There are multiple heat dissipation fins 130 arranged along the circumference of the cooling chamber 700. A fan assembly is provided at the bottom of the cooling chamber 700. The fan assembly is used to drive the air in the cooling chamber 700 to flow. A stirring assembly is also provided in the cooling tank 10; a temperature detection assembly is provided on the water outlet pipe 110, and the temperature detection assembly is used to detect the outlet water temperature of the water outlet pipe 110 and control the start and stop of the fan assembly.

[0030] In actual use of this embodiment, the circulating water that has cooled the production equipment is injected into the water tank 20 through the water inlet pipe 100. At this time, the temperature of the circulating water in the water tank 20 is relatively high. The heat dissipation fins 130 are provided so that the heat of the circulating water in the water tank 20 can be introduced into the cooling chamber 700 through the heat dissipation fins 130, thereby cooling the circulating water in the water tank 20. The fan assembly is provided so that the fan assembly can promote the flow of air in the cooling chamber 700, thereby discharging the heat conducted by the heat dissipation fins 130 out of the cooling chamber 700, thereby improving the heat dissipation efficiency of the heat dissipation fins 130. The outlet pipe 110 is provided so that the cooled circulating water can be discharged through the outlet pipe 110 and cool the production equipment again, thereby realizing the recycling of the circulating water.

[0031] In actual use, the circulating water in the water tank 20 can be stirred by the setting of the stirring assembly, generating turbulence, so that the circulating water in the water tank 20 can be evenly and fully contacted with the inner wall of the water tank 20 and the heat dissipation fins 130, so that the circulating water in the water tank 20 can be cooled more evenly;

[0032] Specifically, the water storage tank 20 and the heat dissipation fins 130 are made of materials with good thermal conductivity (such as aluminum alloy). The heat dissipation fins 130 are integrally formed on the water storage tank 20, and the outer wall of the heat dissipation fins 130 is fixedly connected to the inner wall of the cooling tank 10 by welding, thereby achieving the installation of the water storage tank 20 in the cooling tank 10;

[0033] In this embodiment, the temperature detection component includes a temperature sensor 120 and a controller. The temperature sensor 120 is installed on the water outlet pipe 110 and is used to detect the temperature of the circulating water discharged from the water outlet pipe 110. A temperature threshold is preset in the controller. When the temperature value detected by the temperature sensor 120 is greater than the threshold, the controller controls the fan component to work to promote the cooling of the circulating water. When the temperature value detected by the temperature sensor 120 is less than or equal to the threshold, the controller controls the fan component to stop working to reduce the energy consumption of the fan component, thereby better realizing the control of the temperature of the circulating water.

[0034] Combine Figure 2-Figure 5 As shown, in this embodiment, a plurality of through holes 150 connecting to the cooling cavity 700 are provided along its circumference at the lower position of the outer wall of the cooling tank 10, and the fan assembly includes a plurality of fans 200 fixed on the lower side wall of the cooling cavity 700, and the fans 200 are used to blow the air in the cooling cavity 700 upward.

[0035] In actual use of this embodiment, the upper end of the cooling tank 10 is opened, and the heat dissipation fins 130 are arranged along the height direction of the water storage tank 20, so that an air duct is formed between two adjacent heat dissipation fins 130 in the cooling cavity 700, and the fan 200 is fixedly installed at the lower end opening of each air duct;

[0036] In actual use, the fan 200 and the through-hole 150 are arranged so that the fan 200 can blow the air in the cooling cavity 700 from bottom to top through the opening at the upper end of the cooling cavity 700 out of the cooling cavity 700, and the outside air can enter the cooling cavity 700 through the through-hole 150. As a result, the air in the cooling cavity 700 can flow, thereby taking the heat in the cooling cavity 700 out of the cooling cavity 700, thereby improving the heat dissipation efficiency of the heat dissipation fins 130.

[0037] The fan 200 is electrically connected to the controller, so that the controller can control the start and stop of the fan 200 to achieve the purpose of energy saving.

[0038] Combine Figure 4-Figure 5 As shown, in this embodiment, the stirring assembly includes a rotating shaft 410 rotatably arranged in the water storage tank 20, and a plurality of stirring plates 420 are evenly provided on the outer wall of the rotating shaft 410. The rotation of the rotating shaft 410 is used to drive the stirring plates 420 to stir the circulating water in the water storage tank 20. The stirring assembly also includes a fixed ring 400 fixed on the inner wall of the water storage tank 20, and a tooth groove is provided on the inner wall of the fixing ring 400 along its circumference. Mounting plates 450 are relatively provided on the rotating shaft 410, and a rotatable rotating rod 430 is provided between the mounting plates 450. A gear 510 meshing with the tooth groove is provided at the upper end of the rotating rod 430. A plurality of stirring plates 440 are evenly provided on the outer wall of the rotating rod 430, and the stirring plates 440 are staggered with the corresponding stirring plates 420.

[0039] In actual use of this embodiment, the upper end of the water storage tank 20 is provided with an opening, and a tank cover 160 is fixedly installed at the opening by bolts. The upper end of the rotating shaft 410 is rotatably connected to the tank cover 160, and the lower end is installed on the bottom wall of the water storage tank 20 through a bearing seat. Thus, the rotating shaft 410 is rotatably installed at the center position of the water storage tank 20. The tank cover 160 is provided with a motor 140, and the upper end of the rotating shaft 410 is connected to the output end of the motor 140. The rotating shaft 410 is driven by the motor 140 to rotate, thereby driving the stirring plate 420 to rotate, and stirring the circulating water in the water storage tank 20;

[0040] The rotation of the rotating shaft 410 can drive the mounting plate 450 to drive the rotating rod 430 to revolve around the rotating shaft 410. At the same time, the revolution of the rotating rod 430 can drive the gear 510 to rotate along the tooth groove, so that the gear 510 can drive the rotating rod 430 to rotate, driving the stirring plate 440 to rotate, thereby causing the circulating water in the water storage tank 20 to generate turbulence, so that the circulating water in the water storage tank 20 can be evenly and fully contacted with the inner wall of the water storage tank 20 and the heat dissipation fins 130, so that it can be cooled more evenly. In actual use, by staggering the stirring plate 440 and the corresponding stirring plate 420, the rotation and revolution of the stirring plate 440 driven by the rotating shaft 430 will not interfere with the rotation of the stirring plate 420 driven by the rotating shaft 410. At the same time, the stirring blind area in the water storage tank 20 can be reduced, so that the stirring effect is better.

[0041] The mounting plate 450 is fixedly mounted on the outer side wall of the rotating shaft 410 , and the rotating rod 430 is rotatably mounted on the two mounting plates 450 via bearings, so that the rotating shaft 410 can be rotatably mounted in the water storage tank 20 .

[0042] In actual use, the present invention is as follows: when the circulating water needs to be cooled, the circulating water is added into the water storage tank 20 through the water inlet pipe 100, and the heat dissipation fins 130 are provided so that the heat dissipation fins 130 can conduct the heat of the circulating water in the water storage tank 20 to the cooling chamber 700, and the fan 200 is provided so that the fan 200 can blow the heat on the heat dissipation fins 130 out of the cooling chamber 700 from bottom to top. At the same time, the stirring assembly is provided so that the motor 140 drives the rotating shaft 410 to rotate, so that the rotating shaft 410 can drive the stirring plate 420 to stir the circulating water in the water storage tank 20. The water is stirred, and the rotation of the rotating shaft 410 can drive the mounting plate 450 to drive the rotating rod 430 to revolve around the rotating shaft 410. At the same time, the rotation of the rotating rod 430 can drive the gear 510 to rotate along the tooth groove, so that the gear 510 can drive the rotating rod 430 to rotate, and drive the stirring plate 440 to rotate, thereby causing the circulating water in the water tank 20 to generate turbulence, so that the circulating water in the water tank 20 can be evenly and fully contacted with the inner wall of the water tank 20 and the heat dissipation fins 130, so that it can be cooled more evenly, and the cooled circulating water is discharged from the water tank 20 through the outlet pipe 110.
