[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Example:

[0024] Reference Figure 1-Figure 4 The utility model discloses a high-precision temperature control device for a heat exchanger unit, comprising a water pipe 1, wherein three groups of baffles 2 are arranged inside the water pipe 1, the three groups of baffles 2 are arranged in a ring array and are fixedly connected to the inner wall of the water pipe 1, and one end of the three groups of baffles 2 close to the axis of the water pipe 1 is commonly connected to a rotating tube 3, and three closing blocks 4 are arranged on the outer wall of the rotating tube 3, and the three closing blocks 4 are respectively located between two adjacent groups of baffles 2.

[0025] In this embodiment, when in use, the water pipe 1 is connected to the drain port of the heat exchange unit. When the heat exchange unit extracts the heat in the heat source into the heat exchange medium, when the heat exchange medium is discharged through the drain port, the heat exchange medium enters the interior of the water pipe 1, and the temperature in the heat exchange medium is measured by the temperature sensor 5. When the temperature of the heat exchange medium is high, the rotating tube 3 is controlled to rotate so that the rotating tube 3 drives the closing block 4 to be inserted into the inner side of the baffle 2, so that the volume of the water flow path of the water pipe 1 is increased, and the contact area between the heat exchange medium and the water pipe 1 is increased, so as to dissipate the heat of the heat exchange medium, thereby achieving the purpose of temperature control, and the volume of the water flow path is adjusted by the volume of the closing block 4 inserted into the inner side of the baffle 2, thereby achieving the effect of improving the temperature control accuracy.

[0026] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the baffle 2 includes two arc-shaped plates 21, which are fixedly mounted at the two ends of the water pipe 1, and the centers of the inner and outer arc surfaces of the arc-shaped plates 21 are both on the axis of the water pipe 1, and the opposite sides of the two arc-shaped plates 21 are commonly connected with a closed side plate 22 near the side.

[0027] In this embodiment, through the arrangement of two arc-shaped plates 21 and the closed side plate 22, a U-shaped sliding groove is formed on the inner wall of the water guide pipe 1. When the device does not need to dissipate heat from the heat exchange medium, the closing block 4 is located between two adjacent baffles 2. At this time, the two ends of the closing block 4 and the arc-shaped plates 21 on both sides of the baffle 2 form a circular occlusion, so that the heat exchange medium can only flow through the inner pipe of the rotating pipe 3. When it is necessary to dissipate heat and control the temperature of the heat exchange medium, by rotating the rotating pipe 3, the closing block 4 is inserted into the inside of the baffle 2, so that the water flow can pass through the gap between the two baffles 2 and the rotating pipe 3 and be discharged, achieving the effect of increasing the cross-sectional area of the water flow path inside the water guide pipe 1. Furthermore, the contact area between the heat exchange medium and the water guide pipe 1 is increased, achieving the purpose of dissipating heat and controlling the temperature of the heat exchange medium.

[0028] In a further preferred embodiment of the present utility model, as Figure 1-4 shown, the length of the closing block 4 is equal to the distance between the two arc-shaped plates 21. When the two ends of the closing block 4 are respectively aligned with the two arc-shaped plates 21, the two ends of the closing block 4 are in contact with the arc-shaped plates 21.

[0029] In this embodiment, through the setting that the distance of the closing block 4 is equal to the distance between the two arc-shaped plates 21, when the closing block 4 is inserted between the two arc-shaped plates 21, it is in close contact with the arc-shaped plates 21, achieving the effect of reducing the water flow entering the inside of the baffle 2. Moreover, the outer arc length of the closing block 4 is greater than the outer arc length of the arc-shaped plates 21, so that the two ends of the closing block 4 can be embedded into the inside of the two side baffles 2, achieving the effect of improving the sealing performance between the closing block 4 and the baffle 2 and preventing the heat exchange medium from entering the inside of the baffle 2 when heat dissipation is not required.

[0030] In a further preferred embodiment of the present utility model, as Figure 1-4 shown, a temperature sensor 5 is installed at one end of the inner wall of the rotating pipe 3, and a rotation controller 6 is installed on the inner wall of the water guide pipe 1, and the rotation controller 6 is传动连接 with the rotating pipe 3.

[0031] In this embodiment, through the setting of the temperature sensor 5, it is used to monitor the temperature of the heat exchange medium discharged from one end of the water guide pipe 1 far from the drainage port of the heat exchange unit. When the temperature is relatively high, the temperature data is transmitted to the rotation controller 6, and then the rotation controller 6 controls the deflection angle of the rotating pipe 3, achieving the effect of automatically dissipating heat and controlling the temperature of the heat exchange medium according to the temperature. Moreover, when installing the water guide pipe 1, the temperature sensor 5 is close to the drainage port of the heat exchange unit.

[0032] In a further preferred embodiment of the present utility model, as Figure 1-4 shown, a first arc-shaped platform 7 is arranged at a position corresponding to the pipe orifice of the rotating pipe 3 on the inner wall of the water guide pipe 1. Second arc-shaped platforms 8 are slidably arranged on both sides of the first arc-shaped platform 7, and the inner arc surface of the second arc-shaped platform 8 is fixedly connected with the outer pipe wall of the rotating pipe 3.

[0033] In this embodiment, the heat exchange medium discharged from the drain port of the heat exchange unit is guided by the arrangement of the first curved platform 7. When there is no need to dissipate heat for the heat exchange medium, the second curved platform 8 is located between two adjacent first curved platforms 7. At this time, a trumpet-shaped water guide port is formed between the three first curved platforms 7 and the three second curved platforms 8, so as to achieve the effect of directly introducing the heat exchange medium into the rotating tube 3. When it is necessary to dissipate heat and control the temperature of the heat exchange medium, since the second curved platform 8 is fixedly connected to the outer wall of the rotating tube 3, the second curved platform 8 will be inserted into the first curved platform 7 during the rotation of the rotating tube 3, so that a gap appears in the trumpet-shaped water guide port formed by the first curved platform 7 and the second curved platform 8. At this time, the heat exchange medium will directly contact the water guide pipe 1 after entering the water guide pipe 1, so as to achieve the effect of heat dissipation and temperature control.

[0034] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the outer wall of the water pipe 1 is provided with a plurality of cooling fins 9 arranged in a circular array, and both ends of the cooling fins 9 are provided with fan guides 10 .

[0035] In this embodiment, the cooling fins 9 and the fan 10 are provided to further improve the efficiency of heat dissipation and temperature control.

[0036] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
