Description

Technical Field

[0001] The present application belongs to the technical field of spectrometer measurement devices, and specifically relates to a heat dissipation type full-spectrum direct-reading CCD detector. Background Art

[0002] When the direct-reading CCD is conducting detection, the CCD needs to be electrically connected to the circuit board. Due to the passage of current, heat is generated during the detection process, and this heat will act on the CCD and the circuit board. After each detection work starts, many CCDs are continuously detected, so that a lot of heat is retained on the detector. If this heat is retained on the CCD detector, the electronic components inside the direct-reading CCD detector will be damaged, thereby affecting the normal operation of the direct-reading CCD detector. Therefore, a direct-reading CCD detector that can dissipate heat is urgently needed. Utility Model Content

[0003] The present application aims at the shortcomings of the prior art and designs a heat-dissipating full-spectrum direct-reading CCD detector by setting a liquid cooling module on the carrier body. The detector can dissipate heat for the CCD during the detection process, thus solving the problem that there is currently no CCD detector that can dissipate heat.

[0009] A circuit board is arranged in the second accommodation space;

[0010] The shell is provided with two oppositely arranged through slots, and the conductive pins of the CCD module are electrically connected to the circuit board after passing through the through slots.

[0011] Preferably, the transition channel is in the shape of a letter "I".

[0016] Preferably, it also includes a temperature detector arranged on the carrier body, the temperature detector is connected to the circuit board signal and is used to detect the temperature of the CCD module.

[0017] Compared with the prior art, the heat dissipation type full spectrum direct reading CCD detector provided in this application has the following advantages:

[0028] like Figures 1 to 4 , a heat dissipation type full spectrum direct reading CCD detector. It includes a shell 10; a partition 11; arranged in the shell 10 and defining a first accommodating space 101 and a second accommodating space 102; a bearing body 12, arranged on the shell 10 and used to carry a CCD module 18, and a side of the bearing body 12 contacting the CCD module 18 is made of a heat conductive material; a liquid cooling module 13, arranged in the first accommodating space 101, and including a liquid outlet channel 132 and a liquid inlet channel 131 arranged oppositely, and a transition channel 133, at least part of the liquid outlet channel 132 and the liquid inlet channel 131 are exposed outside the shell 10, and the liquid outlet channel 132 is connected to the liquid inlet channel 131 through the transition channel 133; a circuit board 14, arranged in the second accommodating space 102; the shell 10 is provided with two oppositely arranged through slots 103, and the conductive pins of the CCD module 18 are electrically connected to the circuit board 14 after being passed through the through slots 103.

[0029] The partition 11 divides the housing 10 into two accommodating spaces. The liquid cooling module 13 is arranged in the first accommodating space 101, and the circuit board 14 is arranged in the second accommodating space 102. The circuit board 14 and the CCD module 18 can be separated to achieve the heat dissipation effect on the circuit board 14, and the liquid cooling module 13 is arranged between the two, which can dissipate heat for the CCD module 18 and the circuit board 14 at the same time. At the same time, the side of the carrier body 12 that contacts the CCD module 18 is designed to be made of heat-conducting material, so that the heat generated by the CCD module 18 when working can be adsorbed on the side of the carrier body 12 that is made of heat-conducting material to dissipate the heat of the CCD module 18. Specifically, the cooling medium is introduced into the liquid inlet channel 131, and the cooling medium absorbs heat by contacting the surface of the liquid inlet channel 131, and then the heated cooling medium is discharged again through the transition channel 133 and the liquid outlet channel 132 to achieve heat dissipation for the circuit board 14 and the CCD module 18. The design method of using the transition channel 133 to connect the liquid outlet channel 132 and the liquid inlet channel 131 makes the transition channel 133, the liquid outlet channel 132, and the liquid inlet channel 131 all in a straight line state, so that the process difficulty can be reduced when processing the transition channel 133, the liquid outlet channel 132, and the liquid inlet channel 131 on the shell 10, because in this way, the transition channel 133, the liquid outlet channel 132, and the liquid inlet channel 131 can be directly drilled out by a drill bit. If the transition channel 133, the liquid outlet channel 132, and the liquid inlet channel 131 are not in a straight line state, the shell 10 must be designed as at least an upper plate part and a lower plate part, and then half of the transition channel 133, half of the liquid outlet channel 132, and half of the liquid inlet channel 131 are decomposed and set on the opposing surfaces of the upper half and the lower plate part, and then the upper half of the shell 10 and the lower half of the shell 10 are combined, and then assembly is required, so the process difficulty is large, the process is complicated, and the production efficiency is low. In addition, the design of the two through slots 103 can achieve electrical connection between the CCD module 18 and the circuit board 14 .

[0030] Optionally, the thermally conductive material may be, but is not limited to, a combination of one or more of stainless steel, aluminum alloy, aluminum, copper, iron, gold, silver, silicon, metal alloy, thermally conductive silicone, graphite and graphene. Specifically, in the embodiment of the present application, the thermally conductive material is stainless steel or aluminum alloy.

[0031] Furthermore, please combine Figures 4 to 6 , and also includes a sealing ring 15 . A limiting groove 111 is formed on one side of the partition plate 11 close to the second accommodating space 102 , and the sealing ring 15 is arranged in the limiting groove 111 .

[0032] It can be understood that the design of the sealing ring 15 can prevent external heat from entering between the housing 10 and the CCD module 18, and prevent external heat from entering between the circuit board 14 and the housing 10, thereby further enhancing the heat insulation effect.

[0033] As a preferred method, please refer to Figure 3 The housing 10 is provided with a plurality of heat dissipation holes 104 on one side away from the carrier body 12. The heat dissipation holes 104 can further dissipate heat for the circuit board 14.

[0034] As a preferred method, please continue to refer to Figure 3 The housing 10 is also provided with a wire hole 105 .

[0035] As a preferred method, please combine Figure 1 and Figure 2 A plug 16 for controlling the flow of the cooling medium is also provided at one end of the transition channel 133. The design of the plug 16 can control the flow of the cooling medium in the liquid cooling module 13.

[0036] As a preferred method, please refer to Figure 1 , further comprising a temperature detector 17 disposed on the carrier body 12 , the temperature detector 17 is signal-connected to the circuit board 14 and is used to detect the temperature of the CCD module 18 .

[0037] It can be understood that the temperature detector 17 can monitor the temperature of the CCD module 18 in real time, and can further ensure the safety and stability of the CCD module 18 .
