Description

Technical Field

[0001] This utility model relates to a cooling device, specifically a cooling device for a PCR detector, belonging to the field of optical detection technology. Background Technology

[0002] A real-time quantitative PCR instrument is an instrument that uses fluorescent dyes or fluorescently labeled specific probes to label and track PCR products, monitor the reaction process in real time, and, in conjunction with corresponding software, perform qualitative and quantitative analysis of the products, calculate the initial concentration of the template in the sample to be tested, and then obtain the detection results.

[0003] A search revealed a Chinese patent with publication number CN218026122U that discloses a cooling device for a PCR testing instrument, comprising a heat sink and a cooling fan. The heat sink is connected to a control board, and the cooling fan is connected to the heat sink and located on one side of the heat sink to exhaust airflow for heat dissipation.

[0004] While the aforementioned device improves the heat dissipation capacity of the control board by incorporating a heat sink and a cooling fan on the control board—using the heat sink to absorb and conduct heat while simultaneously activating the cooling fan to increase airflow at the heat sink and reduce the possibility of the control board overheating and burning out due to insufficient heat dissipation through the ventilation holes—these devices suffer from low heat dissipation efficiency due to the heat sink absorbing and conducting heat and then dissipating it through the cooling fan. Furthermore, the high energy consumption of the cooling fan increases cooling costs. Therefore, we provide a cooling device for a PCR testing instrument to address these issues. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a cooling device for a PCR detection instrument, the specific technical solution of which is as follows:

[0006] A cooling device for a PCR testing instrument includes a housing with a sealing cover, a testing instrument body mounted on the housing, a control board mounted on the testing instrument body, a disassembly / removal mechanism on the control board, and a cooling mechanism. The cooling mechanism includes a water pump and a heat-conducting strip. The output end of the water pump is fixedly connected to and communicates with a finned tube. The input end of the water pump is fixedly connected to and communicates with a connecting pipe. The heat-conducting strip has a water inlet hole, is fixedly connected to the finned tube, and communicates with the finned tube. The heat-conducting strip also has a water outlet hole, is fixedly connected to and communicates with the connecting pipe.

[0007] Preferably, the disassembly and assembly mechanism includes two mutually symmetrical fixing bars, both of which are mounted on the control panel, and each of the two fixing bars has two mutually symmetrical slots.

[0008] Preferably, both slots are provided with a first threaded hole, both slots are engaged with a locking block, the locking block is provided with a first through hole, and a threaded post is inserted into the first through hole.

[0009] Preferably, the threaded post is threadedly connected to the first threaded hole, the threaded post is fixedly connected to a rotating disk, the locking block is fixedly connected to a connecting frame, and the connecting frame is fixedly connected to the heat-conducting strip.

[0010] Preferably, the housing is provided with an air drying and filtering mechanism, which includes a receiving frame and a baffle. The receiving frame is fixedly connected to the housing, and the receiving frame has two sets of mutually symmetrical second threaded holes.

[0011] Preferably, the receiving frame has a through groove, the through groove is fixedly connected to a first perforated plate, and an air filter cotton and a drying box are placed inside the through groove.

[0012] Preferably, the baffle is densely covered with air inlets, and the baffle has two sets of mutually symmetrical second through holes. Each set of second through holes is fitted with a screw, and the screw is threadedly connected to the second threaded hole.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This PCR detector uses a cooling device to absorb and conduct heat from the control board via a heat-conducting strip. The coolant inside the heat-conducting strip absorbs the heat, triggering a water pump. The coolant, now cooled, is then pumped into the finned tubes via a connecting pipe and the pump. The stacked arrangement of the finned tubes increases their contact area with the air, and the external fins further dissipate heat from the coolant inside. The cooled coolant is then transported back into the heat-conducting strip, circulating for further cooling. This achieves efficient cooling of the control board while minimizing pump energy consumption and reducing operating costs.

[0015] 2. The PCR detector uses a cooling device that inserts two sets of symmetrical locking blocks into the slots, and then controls two sets of symmetrical threaded columns to pass through the first through hole and connect to the first threaded hole. This allows the cooling mechanism to be quickly installed on the control board. When replacing or repairing the cooling mechanism, the cooling mechanism can be quickly removed by reversing the operation, achieving the purpose of rapid assembly and disassembly of the cooling mechanism. The high-temperature gas inside the device can be exchanged with the external gas through the first perforated plate and the air inlet, cooling the gas inside the device. The external air is filtered and dried through the air filter cotton and the drying box to prevent dust and moisture from entering the device and corroding the internal electronic components. Furthermore, the closed through slot can be quickly opened through the cooperation of the second threaded hole, the second through hole, screws, and baffles to replace the air filter cotton and the drying box, achieving the purpose of rapid filtration and drying of the incoming air.

[0022] The present invention will now be further described with reference to the accompanying drawings.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The device includes a housing 1, a sealing cover 2, a detector body 3, a control board 4, a disassembly mechanism 5, and a cooling mechanism 6. The cooling mechanism 6 includes a water pump 601 and a heat-conducting strip 604. The output end of the water pump 601 is fixedly connected to a finned tube 602 and communicates with it. The input end of the water pump 601 is fixedly connected to a connecting pipe 603 and communicates with it. The heat-conducting strip 604 has a water inlet 605, is fixedly connected to the finned tube 602, and communicates with it. The heat-conducting strip 604 also has a water outlet 606, is fixedly connected to the connecting pipe 603, and communicates with it.

[0024] The heat-conducting strip 604 is a hollow tube with both ends sealed. The water pump 601 in this application is a common electrical device in the prior art, and its model or internal structure will not be described in detail here. It can also be replaced by other power sources. The finned tube 602 is prior art and will not be described in detail. The entire internal space of the water pump 601, finned tube 602, connecting pipe 603, and heat-conducting strip 604 is filled with coolant. The finned tube 602 and heat-conducting strip 604 are made of copper. The heat on the control board 4 is absorbed and conducted through the heat-conducting strip 604, and then the coolant inside the heat-conducting strip 604... The device absorbs heat from the heat-conducting strip 604, controls the water pump 601 to start, and then discharges the coolant that has absorbed heat inside the heat-conducting strip 604 into the interior of the finned tube 602 through the connecting pipe 603 and the water pump 601. The stacked arrangement of the finned tube 602 increases the contact area between the finned tube 602 and the air, and the fins on the outside of the finned tube 602 dissipate heat from the coolant inside the finned tube 602. Then, the cooled coolant is transported into the interior of the heat-conducting strip 604, so that the coolant can circulate and cool down. This achieves the purpose of efficient cooling of the control board 4, and the water pump 601 has low energy consumption, reducing operating costs.

[0025] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The disassembly and assembly mechanism 5 includes two mutually symmetrical fixing bars 501, both of which are mounted on the control plate 4. Each of the two fixing bars 501 has two mutually symmetrical slots 502, and each of the slots 502 has a first threaded hole 503. Each slot 502 is engaged with a locking block 504, and the locking block 504 has a first through hole 505. A threaded post 506 is inserted into the first through hole 505, and the threaded post 506 is threadedly connected to the first threaded hole 503. A rotating disk 507 is fixedly connected to the threaded post 506, and a connecting frame 508 is fixedly connected to the locking block 504. The connecting frame 508 is fixedly connected to the heat-conducting strip 604.

[0026] After the locking block 504 is inserted into the slot 502, the heat-conducting strip 604 will fit against the control plate 4. By inserting two sets of symmetrical locking blocks 504 into the slot 502, and then controlling two sets of symmetrical threaded posts 506 to pass through the first through hole 505 and be threadedly connected to the first threaded hole 503, the cooling mechanism 6 can be quickly installed on the control plate 4. When replacing or repairing the cooling mechanism 6, the cooling mechanism 6 can be quickly removed by reversing the operation, thus achieving the purpose of quick disassembly and assembly of the cooling mechanism 6 in this device.

[0027] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The housing 1 is provided with an air drying and filtering mechanism 7, which includes a receiving frame 701 and a baffle 707. The receiving frame 701 is fixedly connected to the housing 1. The receiving frame 701 has two sets of mutually symmetrical second threaded holes 702. The receiving frame 701 has a through groove 703. The through groove 703 is fixedly connected to a first perforated plate 704. Air filter cotton 705 and a drying box 706 are placed inside the through groove 703. The baffle 707 is densely covered with air inlet holes 708. The baffle 707 has two sets of mutually symmetrical second through holes 709. Screws 710 are inserted into both sets of second through holes 709. The screws 710 are threadedly connected to the second threaded holes 702.

[0028] The drying box 706 here is a box body with densely packed vents and contains drying balls inside. Air can pass through the densely packed vents and gaps between the drying balls. The drying box 706 is existing technology and will not be described in detail. The high-temperature gas inside the device can be exchanged with the external gas through the first perforated plate 704 and the air inlet 708, which cools the gas inside the device. The external air is filtered and dried through the air filter cotton 705 and the drying box 706 to prevent dust and moisture from entering the device and corroding the electronic components inside. The closed through slot 703 can be quickly opened through the cooperation of the second threaded hole 702, the second through hole 709, the screw 710, and the baffle 707 to replace the air filter cotton 705 and the drying box 706, thus achieving the purpose of quickly filtering and drying the incoming air.

[0029] In use, this invention works as follows: The heat is absorbed and conducted through the heat-conducting strip 604 onto the control board 4. Then, the coolant inside the heat-conducting strip 604 absorbs the heat, triggering the water pump 601 to start. The coolant, having absorbed heat, is then discharged into the finned tube 602 through the connecting pipe 603 and the water pump 601. The stacked arrangement of the finned tubes 602 increases the contact area between the finned tubes and the air, and the fins on the outside of the finned tubes 602 dissipate heat from the coolant inside. The cooled coolant is then transported back into the heat-conducting strip 604, allowing for circulating cooling and achieving efficient cooling of the control board 4. Two sets of symmetrical locking blocks 504 are inserted into the slots 502, and two sets of symmetrical threaded posts 506 penetrate the first through hole 505 and are threadedly connected to the first threaded hole 503. The cooling mechanism 6 can be quickly installed on the control board 4. When replacing or repairing the cooling mechanism 6, the cooling mechanism 6 can be quickly removed by reversing the operation, thus achieving the purpose of quick installation and removal of the cooling mechanism 6. The high-temperature gas inside the device can be exchanged with the external gas through the first perforated plate 704 and the air inlet 708, which cools the gas inside the device. The external air is filtered and dried through the air filter cotton 705 and the drying box 706 to prevent the external air from carrying dust into the device and to prevent the external air from carrying moisture into the device, which could corrode the electronic components inside the device. Furthermore, the closed through slot 703 can be quickly opened through the cooperation of the second threaded hole 702, the second through hole 709, the screw 710, and the baffle 707 to replace the air filter cotton 705 and the drying box 706, thus achieving the purpose of quick filtration and drying of the incoming air.
