[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-3A cooling device for a photometer includes a photometer body 1. A support frame 2 is provided on the front and rear sides of the photometer body 1. A left plate 8 is fixedly connected to one end of the support frame 2, and a right plate 9 is fixedly connected to the other end of the support frame 2. A heat absorption pipe 3 is fixedly connected to the upper end of the interior of the support frame 2. The heat absorption pipe 3 is in contact with the bottom and side wall of the photometer body 1. A heat release pipe 4 is fixedly connected to one end of the heat absorption pipe 3 and is communicated with the heat release pipe 4. A micro water pump 5 is provided at one end between the heat absorption pipe 3 and the heat release pipe 4. An end of the heat release pipe 4 away from the heat absorption pipe 3 is fixedly connected to the water outlet of the micro water pump 5, and an end of the heat absorption pipe 3 away from the heat release pipe 4 is fixedly connected to the water inlet of the micro water pump 5.

[0022] In the cooling device of the photometer in the present invention, the coolant inside the heat-absorbing pipe 3 absorbs the heat emitted by the photometer body 1, and then the coolant enters from the water inlet of the micro water pump 5, and then enters the heat release pipe 4 from the water outlet of the micro water pump 5. After the coolant enters the heat release pipe 4, the heat is released in the form of thermal radiation, thereby reducing the temperature of the coolant. After releasing the heat, the coolant enters the heat-absorbing pipe 3 again, further reducing the temperature of the photometer body 1. In this way, the temperature of the photometer body 1 can always be maintained in a suitable range, avoiding the impact of high temperature on the performance and measurement accuracy of the photometer body 1. At the same time, since the micro water pump 5 is an existing mature product, it will not be described in detail here. In addition, the structure of the photometer body 1 in the present invention is similar to the prior art, and a spectrophotometer structure disclosed in the patent authorization announcement number CN221631277U is similar, so it will not be elaborated on here.

[0023] like Figure 1 and Figure 2 As shown, a heat insulation board 7 is provided between the heat absorbing pipe 3 and the heat releasing pipe 4 , and the heat insulation board 7 is fixedly connected to the support frame 2 .

[0024] Specifically, the heat absorbing pipe 3 and the heat releasing pipe 4 are isolated by the heat insulating plate 7 to prevent the heat released by the heat releasing pipe 4 from being absorbed by the heat absorbing pipe 3 , which would result in a decrease in the cooling effect of the entire device.

[0025] like Figure 1 and Figure 2 As shown, a plurality of heat dissipation fins 6 are fixedly connected to the outer wall of the heat release pipe 4 , and the plurality of heat dissipation fins 6 are distributed at equal intervals.

[0026] Specifically, the heat dissipation fins 6 can be made of copper or aluminum to improve the heat dissipation effect of the heat dissipation pipe 4. At the same time, the heat dissipation fins 6 distributed at equal intervals have a higher heat dissipation effect.

[0027] like Figure 2 and Figure 3As shown, a slide groove 13 is provided on the top of the support frame 2, and a slider 12 is slidably connected inside the slide groove 13. A traction frame 11 is fixed to the top of the slider 12. An elastic dustproof cloth 10 is fixed to the side of the traction frame 11 close to the right side plate 9, and the other end of the elastic dustproof cloth 10 is fixed to the right side plate 9.

[0028] Specifically, after the photometer body 1 is used, the traction frame 11 can be slid to drive the elastic dustproof cloth 10 to cover the top of the photometer body 1, thereby protecting the photometer body 1 and preventing dust from falling on the photometer body 1.

[0029] like Figure 2 and Figure 3 As shown, a magnetic block 14 is fixedly connected to one side of the traction frame 11 close to the left side plate 8 , and the magnetic block 14 and the left side plate 8 are attracted to each other.

[0030] Specifically, when the traction frame 11 moves to the position of the left side plate 8, the magnetic block 14 will be attracted to the left side plate 8, thereby fixing the traction frame 11 to prevent the traction frame 11 from opening by itself, causing the elastic dustproof cloth 10 to lose its protective effect.

[0031] like Figure 2 and Figure 3 As shown, the cross sections of the slider 12 and the chute 13 are both trapezoidal. The trapezoidal slider 12 is more difficult to separate from the chute 13, so that the connection between the traction frame 11 and the support frame 2 can be more stable.

[0032] like Figure 2 As shown, the cross section of the heat absorbing pipe 3 is square. The square heat absorbing pipe 3 has a larger contact area with the photometer body 1 and a better heat absorbing effect.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention.
