[0022] Example 1

[0023] like Figure 1-4As shown, it is the first embodiment of the utility model, which provides a temperature control and cooling device for a spectrometer, including a spectrophotometer body 1, the spectrophotometer body 1 also includes a shell 11, a detection chamber 12 is opened on the top of the shell 11, the detection chamber 12 is used to provide an experimental space, the top of the shell 11 is hinged with a cover plate 13, the cover plate 13 is used to seal the inner cavity of the detection chamber 12, the inner cavity of the shell 11 is provided with a ventilation component 14, the ventilation component 14 is used to ventilate and dissipate heat of the inner cavity of the shell 11, a cooling component 2 is installed at the bottom of the inner cavity of the shell 11, the cooling component 2 is used to cool the inner cavity of the detection chamber 12, and a control unit 3 is installed on the surface of the spectrophotometer body 1, and the control unit 3 is used to control the start and stop of the cooling component 2.

[0024] like Figure 1-2 As shown, the temperature of the inner cavity of the detection chamber 12 can be set by the control unit 3. The control unit 3 detects the temperature of the inner cavity of the detection chamber 12 and controls the start and stop of the cooling component 2, so that the cooling component 2 can cool the inner cavity of the detection chamber 12. The ventilation component 14 can ventilate the inner cavity of the shell 11, so that the air in the inner cavity of the shell 11 can be circulated and the equipment in the inner cavity of the shell 11 can be cooled. The cover plate 13 can seal the inner cavity of the detection chamber 12 to prevent the external environment from affecting the experimental process.

[0025] In this embodiment, Figure 2 As shown, the ventilation assembly 14 also includes ventilation slots 141, which are opened on both sides of the inner cavity of the shell 11. A first ventilation fan 142 is installed on the back of the inner cavity of the shell 11, and a second ventilation fan 143 is installed on the front of the inner cavity of the detection chamber 12.

[0026] like Figure 2 As shown, the centrifugal force generated by the high-speed rotation of the first ventilation fan 142 can discharge the heat from the inner cavity of the shell 11, and the external fresh air flows into the inner cavity of the shell 11 through the ventilation slots 141, so that the air in the inner cavity of the shell 11 remains circulating, and the centrifugal force generated by the high-speed rotation of the second ventilation fan 143 can extract the heat from the inner cavity of the first ventilation fan 142, thereby improving the heat dissipation efficiency of the inner cavity of the detection chamber 12.

[0027] Example 2

[0028] Reference Figure 2-3 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0029] In this embodiment, the cooling component 2 also includes a water tank 201, a circulating pump 202 is fixedly connected to the bottom of the inner cavity of the shell 11 and located on the left side of the cooling component 2, a water cooling block 203 is installed at the bottom of the inner cavity of the detection chamber 12, a heat exchanger 204 is fixedly connected to the bottom of the inner cavity of the shell 11 and located at the rear of the cooling component 2, and a cooling fan 205 is installed on the top of the heat exchanger 204.

[0030] A water outlet pipe 206 is connected to one side of the water tank 201, and an end of the water outlet pipe 206 away from the water tank 201 is connected to the water inlet end of the circulating pump 202, and the water outlet end of the circulating pump 202 is connected to a first connecting pipe 207, and an end of the first connecting pipe 207 away from the circulating pump 202 is connected to the water inlet end of the water cooling block 203, and the water outlet end of the water cooling block 203 is connected to a second connecting pipe 208, and an end of the second connecting pipe 208 away from the water cooling block 203 is connected to the water inlet end of the heat exchanger 204, and the water outlet end of the heat exchanger 204 is connected to a water inlet pipe 209, and an end of the water inlet pipe 209 away from the heat exchanger 204 is connected to the water inlet end of the water tank 201.

[0031] like Figure 2-3 As shown, the water tank 201 is used to store the coolant. The centrifugal force generated by the high-speed rotation of the circulating pump 202 drives the coolant in the inner cavity of the water tank 201 to be guided to the inner cavity of the water-cooling block 203 through the water outlet pipe 206 and the first connecting pipe 207. The water-cooling block 203 can absorb the heat of the inner cavity of the detection chamber 12, so that the heat follows the coolant and is guided to the inner cavity of the heat exchanger 204 through the second connecting pipe 208. The cooling fan 205 and the heat exchanger 204 cooperate to cool the coolant, thereby cooling the coolant. The cooled coolant returns to the inner cavity of the water tank 201 through the water inlet pipe 209, so that the inner cavity of the detection chamber 12 can be cooled by circulation. A set of thermoelectric coolers can also be added to the inner cavity of the detection chamber 12, and the inner cavity of the detection chamber 12 can also be cooled by compressor refrigeration, so as to improve the cooling efficiency of the inner cavity of the detection chamber 12.

[0032] Example 3

[0034] In this embodiment, the control unit 3 further includes a temperature controller 301 , which is fixedly connected to the front side of the housing 11 , and a temperature sensor 302 is fixedly connected to the back side of the inner cavity of the detection chamber 12 .

[0035] The output end of the temperature sensor 302 is electrically connected to the input end of the temperature controller 301 , and the output end of the temperature controller 301 is electrically connected to the input end of the cooling component 2 .

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, the temperature value of the inner cavity of the detection chamber 12 is set by the temperature controller 301. When the temperature sensor 302 detects that the temperature of the inner cavity of the detection chamber 12 exceeds the preset value, the temperature sensor 302 feeds back a signal to the temperature controller 301, so that the temperature controller 301 controls the cooling component 2 to start cooling the inner cavity of the detection chamber 12.

[0037] When in use, firstly, the temperature value of the inner cavity of the detection chamber 12 is set through the temperature controller 301. When the temperature sensor 302 detects that the temperature of the inner cavity of the detection chamber 12 exceeds the preset value, the temperature sensor 302 sends a signal to the temperature controller 301. The temperature controller 301 controls the cooling component 2 to start. The centrifugal force generated by the high-speed rotation of the circulating pump 202 drives the coolant in the inner cavity of the water tank 201 to be guided to the inner cavity of the water cooling block 203 through the water outlet pipe 206 and the first connecting pipe 207. The water cooling block 203 can absorb the heat of the inner cavity of the detection chamber 12, so that the heat follows the coolant through the second connecting pipe 208 to be guided to the inner cavity of the heat exchanger 204, thereby cooling down. The fan 205 and the heat exchanger 204 cooperate to cool the coolant, thereby cooling the coolant. The cooled coolant returns to the inner cavity of the water tank 201 through the water inlet pipe 209, and circulates to cool the inner cavity of the detection chamber 12. The centrifugal force generated by the high-speed rotation of the first ventilation fan 142 can discharge the heat from the inner cavity of the shell 11, and the external fresh air flows into the inner cavity of the shell 11 through the ventilation groove 141, so that the air in the inner cavity of the shell 11 remains circulating. The centrifugal force generated by the high-speed rotation of the second ventilation fan 143 can extract the heat from the inner cavity of the first ventilation fan 142, thereby improving the heat dissipation efficiency of the inner cavity of the detection chamber 12.
