Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sample detection, and particularly relates to a temperature control device of sample detection equipment and the sample detection equipment. Background Art
[0002] Polymerase chain reaction (PCR) is a molecular biology technique used to amplify specific nucleic acid fragments and can be considered a special form of nucleic acid replication outside of an organism. PCR consists of a cycle of several reactions, including high-temperature denaturation, low-temperature annealing (renaturation), and thermophilic extension. The sample to be tested undergoes multiple cycles of heating and cooling, rapidly amplifying the target nucleic acid. It has the characteristics of strong specificity, high sensitivity, ease of operation, and time-saving. When the reaction tube containing the sample to be tested is installed in a PCR instrument for cyclic heating and cooling, the reaction tube heats up quickly. However, the heated reaction tube is difficult to cool down quickly in a closed PCR instrument. The heat generated during the heating process accumulates in the reaction tube, and the reaction tube takes a long time to cool down, affecting the accuracy of the test results. Utility Model Content

[0049] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.
[0050] The temperature control device of the sample detection equipment of the present invention will be described below with reference to the accompanying drawings.
[0051] like Figures 1 to 7 As shown, the utility model provides a temperature control device for a sample detection device, which includes a heating plate 10, a shell 20 and a heat dissipation module. The shell 20 is formed with a socket 21 for the reaction tube 200 to extend into. The heat dissipation module is arranged in the shell 20 and includes a heat dissipation component 30, a heat conductive seat 40 and a heat dissipation fan 50. The heat dissipation component 30 is formed with an installation space 31 connected to the socket 21. The heating plate 10 is arranged in the installation space 31 and connected to the heat dissipation component 30. The heat conductive seat 40 is arranged between the heat dissipation component 30 and the heat dissipation fan 50, and the heat conductive seat 40 is formed with a heat conduction channel 41. The two ends of the heat conduction channel 41 are respectively arranged in a one-to-one correspondence with the heat dissipation component 30 and the heat dissipation fan 50.
[0052] Specifically, the heat dissipation component 30, the heat-conducting seat 40 and the heat dissipation fan 50 are all arranged in the shell 20. A heat-conducting channel 41 is formed in the heat-conducting seat 40. One end of the heat-conducting channel 41 is arranged corresponding to the heat dissipation component 30, and the other end of the heat-conducting channel 41 is arranged corresponding to the heat dissipation fan 50. The heat dissipation component 30 is formed with an installation space 31, and a heating plate 10 is arranged in the installation space 31. A socket 21 connected to the installation space 31 is opened at a position corresponding to the heating plate 10 on the shell 20. The reaction tube 200 can extend from the socket 21 into the installation space 31 and fit into the heating plate 10. The heating plate 10 heats the reaction tube 200. The reaction tube 200 is heated up quickly. When the reaction tube 200 is heated, the heating plate 10 stops heating. The heat on the reaction tube 200 and the heating plate 10 can be quickly transferred to the heat dissipation assembly 30. The heat dissipation fan 50 is started to make the air in the heat conduction channel 41 flow quickly, thereby making the heat absorbed by the heat dissipation assembly 30 quickly transferred to the heat conduction channel 41. The hot air in the heat conduction channel 41 flows along the extension direction of the heat conduction channel 41 and dissipates heat during the flow. The heat conduction and dissipation speed is fast, which effectively prevents heat accumulation on the reaction tube 200 and realizes rapid cooling of the reaction tube 200.
[0053] In an embodiment of the present utility model, the heat dissipation assembly 30 includes a first heat dissipation seat 32 and a second heat dissipation seat 33 arranged opposite to each other, and an installation space 31 is formed between the first heat dissipation seat 32 and the second heat dissipation seat 33. The number of heating plates 10 is set to two, and the two heating plates 10 are respectively arranged on the side of the first heat dissipation seat 32 and the second heat dissipation seat 33 facing the installation space 31, and an insertion gap 11 is formed between the two heating plates 10.
[0054] like Figures 2 to 5 As shown, the first heat sink 32 and the second heat sink 33 are arranged in the shell 20 at intervals along the up and down directions, and an installation space 31 is formed between the first heat sink 32 and the second heat sink 33. A heating plate 10 is respectively provided on one side of the first heat sink 32 and the second heat sink 33 facing the installation space 31, and an insertion gap 11 is formed between the two heating plates 10 for the reaction tube 200 to extend into. The reaction tube 200 extends from the socket 21 into the insertion gap 11, so that the two heating plates 10 are respectively fitted with the upper and lower sides of the reaction tube 200. The two heating plates 10 can both be used to heat the reaction tube 200, thereby improving the heating rate of the reaction tube 200. After the heating of the reaction tube 200 is completed, the heat on the upper and lower sides of the reaction tube 200 and the heat on the two heating plates 10 can be quickly conducted to the first heat sink 32 and the second heat sink 33 respectively. One end of the heat conducting seat 40 is arranged corresponding to the first heat sink 32 and the second heat sink 33. When the cooling fan 50 is turned on, the heat absorbed by the first heat sink 32 and the second heat sink 33 can be quickly conducted to the heat conducting channel 41 and dissipated. The first heat sink 32 and the second heat sink 33 dissipate heat from the upper and lower sides respectively, further accelerating the cooling speed.
[0055] In the embodiment of the present invention, a support block 22 is provided on the housing 20. The support block 22 extends toward the installation space 31 and is sandwiched between the first heat sink 32 and the second heat sink 33. The size of the support block 22 is gradually reduced from the housing 20 toward the installation space 31. Figures 2 to 5 and Figure 8 As shown, a support block 22 is provided on the side of the shell 20 facing the installation space 31, and the support block 22 extends into the installation space 31. The first heat sink 32 and the second heat sink 33 are supported on the upper and lower sides of the support block 22 respectively. The dimension of the support block 22 along the up and down direction is the height dimension. The height dimension of the support block 22 gradually decreases from the shell 20 toward the installation space 31, so that the distance between the first heat sink 32 and the second heat sink 33 is gradually set from the front to the back direction, and then the dimension of the insertion gap 11 is gradually set from the front to the back direction, so that the reaction tube 200 is inserted tighter and tighter in the process of extending into the insertion gap 11, thereby improving the insertion stability of the reaction tube 200, and enabling the two heating plates 10 to respectively press against the upper and lower sides of the reaction tube 200, thereby improving the heating stability and the heating rate.
[0056] Furthermore, the first heat sink 32 includes a first heat conductive block 321 and a first heat sink 322, the second heat sink 33 includes a second heat conductive block 331 and a second heat sink 332, an installation space 31 is formed between the first heat conductive block 321 and the second heat conductive block 331, the two heating plates 10 are respectively arranged on the first heat conductive block 321 and the second heat conductive block 331 in a one-to-one correspondence, the first heat sink 322 is arranged on the side of the first heat conductive block 321 facing away from the installation space 31, the second heat sink 332 is arranged on the side of the second heat conductive block 331 facing away from the installation space 31, and the support block 22 is clamped between the first heat conductive block 321 and the second heat conductive block 331.
[0057] like Figures 2 to 5 As shown, the first heat-conducting block 321 and the second heat-conducting block 331 are arranged at intervals to form an installation space 31. A plurality of first heat-conducting fins 322 are provided on the side of the first heat-conducting block 321 facing away from the installation space 31, and the plurality of first heat-conducting fins 322 are arranged at intervals on the first heat-conducting block 321. A plurality of second heat-conducting fins 332 are provided on the side of the second heat-conducting block 331 facing away from the installation space 31, and the plurality of second heat-conducting fins 332 are arranged at intervals on the second heat-conducting block 331. The heat on the two heating plates 10 can be respectively conducted to the first heat-conducting block 321 and the second heat-conducting block 331, so that the first heat-conducting block 321 disperses and conducts the heat to the plurality of first heat-conducting fins 322, and the second heat-conducting block 331 disperses and conducts the heat to the plurality of second heat-conducting fins 332, thereby accelerating the heat dissipation speed, further improving the cooling rate, and realizing a rapid heating and cooling cycle of the reaction tube 200.
[0058] In an embodiment of the present utility model, the first heat-conducting block 321 includes a first heat-conducting part 3211 and a first support part 3212, the second heat-conducting block 331 includes a second heat-conducting part 3311 and a second support part 3312, and the two heating plates 10 are respectively arranged on the first heat-conducting part 3211 and the second heat-conducting part 3311 in a one-to-one correspondence. The first support part 3212 is arranged on the side of the first heat-conducting part 3211 facing the installation space 31, and the second support part 3312 is arranged on the side of the second heat-conducting part 3311 facing the installation space 31, and the support block 22 is clamped between the first support part 3212 and the second support part 3312.
[0059] like Figures 2 to 5As shown, the first heat conducting part 3211 and the second heat conducting part 3311 are spaced apart and form an installation space 31, and the first support part 3212 and the second support part 3312 are respectively provided on the first heat conducting part 3211 and the second heat conducting part 3311, and the first support part 3212 and the second support part 3312 are respectively supported on the upper and lower sides of the support block 22 in a one-to-one correspondence, so that the distance between the first heat conducting part 3211 and the second heat conducting part 3311 gradually decreases from the front to the rear, thereby causing the size of the insertion gap 11 to gradually decrease from the front to the rear. The resistance of the reaction tube 200 gradually increases during the process of extending into the insertion gap 11. The two heating plates 10 cooperate to clamp the reaction tube 200, thereby improving the insertion stability of the reaction tube 200. The heating plates 10 adhere to and press the reaction tube 200, thereby improving the heat conduction rate and realizing a rapid temperature rise and fall cycle of the reaction tube 200.
[0060] Furthermore, a heat-conducting layer is coated on the side of the heating plate 10 facing away from the insertion gap 11, that is, a heat-conducting layer is sandwiched between the first heat-conducting part 3211 and the corresponding heating plate 10, and a heat-conducting layer is sandwiched between the second heat-conducting part 3311 and the corresponding heating plate 10. The heat-conducting layer can quickly conduct the heat generated by the corresponding heating plate 10 to the first heat-conducting part 3211 or the second heat-conducting part 3311, further improving the cooling rate. In addition, in a preferred embodiment of the present invention, the heating plate 10 can adopt a thermoelectric semiconductor heating patch or Peltier heating plate 10 that can generate heat in the prior art. By coating thermal grease on the heating plate 10 to form a heat-conducting layer, it has the advantages of saving production costs and good heat conduction effect.
[0061] In the embodiment of the present utility model, the heat dissipation assembly 30 further includes an elastic connection clip 34, which is used to clamp the first support portion 3212, the support block 22 and the second support portion 3312. Figures 2 to 5 and Figure 8 As shown, the first support portion 3212 and the second support portion 3312 cooperate to clamp the support block 22 located between the first support portion 3212 and the second support portion 3312, and the elastic connecting clip 34 is used to clamp the outside of the first support portion 3212 and the second support portion 3312 to clamp the first support portion 3212, the support block 22 and the second support portion 3312. The connection strength is large, ensuring that the first support portion 3212 and the second support portion 3312 can be tilted and supported on the upper and lower sides of the support block 22 respectively, and the elastic connecting clip 34 has elastic deformation ability. During disassembly and assembly, it is only necessary to overcome the elastic restoring force of the elastic connecting clip 34 to clamp the elastic connecting clip 34 on the outside of the first support portion 3212 and the second support portion 3312 or remove the elastic connecting clip 34. Disassembly and assembly are convenient and quick, and the connection is stable and reliable.
[0062] Furthermore, if Figures 1 to 3 and Figure 8As shown, the shell 20 includes a cover 23 and a mounting plate 24. The heating plate 10 and the heat dissipation module are both installed in the cover 23.
