Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation of medical devices, and particularly to an active energy-saving and environmental protection heat dissipation system for a biochemical analyzer. Background Art

[0002] The fully automatic biochemical immunoassay analyzer is a highly precise instrument integrating optics, machinery, electronics, software, and clinical application technologies. On the one hand, the accuracy and reliability of its precision mechanical components are greatly affected by dust, and the instrument needs to be kept as airtight as possible to prevent dust. On the other hand, there are many heat-generating components, such as electronic devices, power supplies, light sources, and semiconductor refrigeration radiators, which require a good ventilation environment for heat dissipation. Therefore, the fully automatic biochemical immunoassay analyzer requires a good dust-proof and heat dissipation system design.

[0003] Currently, in the fully automatic biochemical immunoassay analyzer, the most common method is to design a negative pressure heat dissipation system by implementing forced ventilation, that is, the exhaust fan exhausts air outward for heat dissipation. Such a heat dissipation method will cause the overall or local pressure inside the fully automatic biochemical immunoassay analyzer to be less than the external air pressure, and since the air inlet and the outer shell of the biochemical analyzer cannot be made absolutely airtight, external dust will be sucked into the instrument, resulting in contamination of the optical path and reaction cups, reducing the test accuracy and causing high-precision mechanical failures and shortening the service life of electronic devices, thereby affecting the reliability of the instrument's operation, increasing the maintenance difficulty, and increasing the use and maintenance costs. Moreover, the internal structure of the fully automatic biochemical immunoassay analyzer is complex. In order to improve the heat dissipation effect, a large-volume exhaust fan and an increased rotation speed are often required, which will bring high-decibel noise pollution, and is neither energy-saving nor environmentally friendly.

[0031] Please refer to Figures 1 to 7 , the present invention provides an active energy-saving and environmental protection heat dissipation system for a biochemical analyzer, comprising a box body 1, a dust-proof device 2 and an air inlet device 3. The box body 1 has a through hole 11 and a plurality of heat dissipation grooves 12. The through hole 11 is located on one side of the box body 1, and the plurality of heat dissipation grooves 12 are distributed on one side of the box body 1 and on the opposite surface of the through hole 11. The dust-proof device 2 includes a baffle 21 and a dust-proof net 22. The baffle 21 is fixedly connected to the box body 1 and covers the through hole 11. The baffle 21 has a mounting slot 211 and a plurality of air inlet grooves 212. The plurality of air inlet grooves 212 are evenly distributed on the baffle 21. The mounting slot 211 is located on the outer periphery of the plurality of air inlet grooves 212. The dust-proof net 22 is detachably connected to the baffle 21, covers the plurality of air inlet grooves 212 and is located in the mounting slot 211. The air inlet device 3 is located inside the box body 1. The air inlet device 3 includes a fan mounting member 31 and a plurality of heat dissipation fans 32. The fan mounting member 31 is detachably connected to the box body 1 and is located on the side close to the baffle 21. The plurality of heat dissipation fans 32 are rotatably connected to the fan mounting member 31, and the air inlet direction is towards the plurality of air inlet grooves 212.

[0032] In this embodiment, the box body 1 is the outer shell of a fully automatic biochemical immunoassay analyzer, and electronic devices, a power supply, a light source, a semiconductor refrigeration radiator, etc. for analysis are arranged inside. The dust-proof device 2 is used to prevent external dust from entering the box body 1. The air inlet device 3 is located at the boundary between the inside and outside of the box body 1 and is used to dissipate heat from the inside of the box body 1. The through hole 11 is located at the front end of the box body 1, and a plurality of heat dissipation grooves 12 are located at the rear end of the box body 1, that is, near the components that generate more heat. The through hole 11 and the plurality of heat dissipation grooves 12 are located on opposite surfaces in the air outlet direction of the air inlet device 3, having the effect of convective heat dissipation. The air inlet device 3 includes a fan mounting member 31 and a plurality of heat dissipation fans 32. The fan mounting member 31 is made by sheet metal processing and is used to mount the plurality of heat dissipation fans 32. The air inlet directions of the plurality of heat dissipation fans 32 face the plurality of air inlet grooves 212, and the air outlet directions face the inside of the box body 1. When the plurality of heat dissipation fans 32 work, external air enters the inside of the box body 1, and the heat and some dust inside the box body 1 are dissipated from the box body 1 through the plurality of heat dissipation grooves 12, and the pressure inside the box body 1 is higher than the external air pressure, preventing external dust from entering the inside of the box body 1 through gaps. The dust-proof device 2 includes a baffle 21 and a dust-proof net 22. The baffle 21 covers the through hole 11. The baffle 21 has a plurality of air inlet grooves 212. The dust-proof net 22 covers the plurality of air inlet grooves 212, that is, completely covers the air inlet end of the air inlet device 3. Installation slots 211 are arranged outside the plurality of air inlet grooves 212. The dust-proof net 22 is located in the installation slots 211 for easy replacement. The range of the plurality of air inlet grooves 212 is equal to or slightly larger than the air inlet area of the air inlet device 3. The dust-proof net 22 installed in the installation slots 211 completely covers the air inlet grooves 212 to prevent external dust from entering the inside of the box body 1 through the air inlet grooves 212, and the inner side of the baffle 21 closely adheres to the air inlet end of the air inlet device 3 to prevent air from entering from the side. Specifically, when the plurality of heat dissipation fans 32 rotate, external air passes through the dust-proof net 22 from the plurality of air inlet grooves 212, and the heat inside the box body 1 is dissipated through the plurality of heat dissipation grooves 12 at the rear end, which can not only achieve heat dissipation but also effectively prevent dust.

[0033] An active energy-saving and environmental protection heat dissipation system for a biochemical analyzer of the present invention. The through hole 11 and the heat dissipation slot 12 on the box body 1 are located on opposite surfaces. The baffle 21 covers the through hole 11. A plurality of air intake slots 212 are evenly distributed on the baffle 21. The dust-proof net 22 covers the plurality of air intake slots 212. A plurality of heat dissipation fans 32 are rotationally connected to the fan mounting member 31, and the air intake direction is towards the plurality of air intake slots 212. The control device 4 is arranged inside the box body 1 for detecting temperature. The series structure 5 of the refrigeration air ducts and the combined structure 6 of the refrigeration air ducts are located above the box body 1 and between the air intake device 3 and the heat dissipation slot 12. Air is sent into the box body 1 through the air intake device 3, keeping the air intake volume greater than 50% of the total air volume of the heat dissipation fans 32, maintaining a positive pressure inside the box body 1, and discharging internal heat and dust impurities through the heat dissipation holes. At the same time, the dust-proof net 22 enhances the dust-proof effect, thereby solving the problems of being able to dissipate heat, prevent dust, and meeting the requirements of energy conservation and environmental protection, low cost, low noise, and easy maintenance.

[0034] Further, the active energy-saving and environmental protection heat dissipation system of the biochemical analyzer further includes a control device 4. The control device 4 includes a temperature sensing bracket 41 and a temperature sensor 42. The number of the temperature sensing brackets 41 and the temperature sensors 42 is multiple. The multiple temperature sensing brackets 41 are respectively installed on one side close to the air intake slot 212 and the reaction disk inside the box body 1. Each temperature sensor 42 is fixedly connected to each temperature sensing bracket 41.

[0035] In this embodiment, the temperature bracket is used to support the temperature sensor 42. The temperature sensor 42 refers to a sensor that can sense temperature and convert it into an available output signal. It is an induction device of a CPU with an ADC and corresponding execution circuits. The sensing part does not contact the temperature sensing bracket 41 to accurately collect and feedback the temperature state at a certain point inside the box body 1. The temperature sensor 42 detects the temperature inside the box body 1 and transmits it to the controller inside the box body 1. The controller controls the driving part of the heat dissipation fan 32 to change the rotation speed to perform heat dissipation processing according to the situation. When the environment and the temperature inside the box body 1 are relatively low, the rotation speed of the heat dissipation fan 32 will be reduced at this time, slowing down or stopping the air exchange inside and outside, ensuring that the temperature inside the box body 1 meets the best working state, which is beneficial for the temperature of the reaction disk to reach 37 degrees faster and more stably. After the heat dissipation fan 32 reduces its speed, the noise is reduced, and the electric energy required for heating the reaction disk is also reduced synchronously, thereby achieving the purpose of energy conservation and environmental protection. When the environment and the temperature inside the box body 1 are relatively high, the temperature control system will increase the rotation speed of the heat dissipation fan 32 according to the feedback temperature to ensure the best working state and energy-saving effect of the instrument. The model of the temperature sensor 42 can be 602F - 3500F.

[0036] Further, the dust-proof net 22 has a handle 221, and the handle 221 is located on the side of the baffle 21 away from the box body 1.

[0037] In this embodiment, it can be freely installed and removed in the installation slot 211 of the baffle 21 without the aid of any tools, which is convenient for cleaning and maintenance.

[0038] Further, the box body 1 also has two first heat dissipation holes 13, and the two first heat dissipation holes 13 are located on the side close to the heat dissipation groove 12.

[0039] In this embodiment, the first heat dissipation holes 13 are arranged at the rear end of the box body 1 for accelerating heat dissipation.

[0040] Further, the active energy-saving and environmental protection heat dissipation system of the biochemical analyzer further includes a refrigeration air duct series structure 5, and the refrigeration air duct series structure 5 is communicated with the box body 1 and the two first heat dissipation holes 13 and is located between the air inlet device 3 and the two first heat dissipation holes 13.

[0041] In this embodiment, the refrigeration air duct series structure 5 is located on the large bottom plate at the upper end of the box body 1 for directly discharging the hot air of the air inlet air volume of the heat dissipation fan 32 through the first heat dissipation holes 13.

[0042] Further, the refrigeration air duct series structure 5 includes two refrigeration air duct components 51, and each refrigeration air duct component 51 is communicated with the box body 1 and each first heat dissipation hole 13. The refrigeration air duct component 51 includes a first air inlet duct 511, an air outlet duct 512, a connecting duct 513 and two first axial fans 514. The first air inlet duct 511 is communicated with the box body 1 and is located above the air inlet direction of the heat dissipation fan 32. The air outlet duct 512 is communicated with the first heat dissipation hole 13. The connecting duct 513 is communicated with the first air inlet duct 511 and the air outlet duct 512 and is located between the first air inlet duct 511 and the air outlet duct 512. The two first axial fans 514 are respectively located between the first air inlet duct 511 and the connecting duct 513 and between the connecting duct 513 and the air outlet duct 512.

[0043] In this embodiment, the series-connected structure 5 of the refrigeration air ducts includes two refrigeration air duct assemblies 51. The two refrigeration air duct assemblies 51 correspond to the two first heat dissipation holes 13 one by one, and are used to dissipate the heat at different positions in the box body 1 on the side slightly away from the baffle 21 after refrigeration through the first heat dissipation holes 13. Specifically, it is on the side opposite to the heat dissipation groove 12 and slightly away from the baffle 21. The box body 1 is sequentially communicated with the first air inlet air duct 511, the connecting air duct 513, the air outlet air duct 512 and the first heat dissipation hole 13. The first axial flow fan 514 between the first air inlet air duct 511 and the connecting air duct 513 is a primary axial flow fan, and the first axial flow fan 514 between the connecting air duct 513 and the air outlet air duct 512 is a secondary axial flow fan. When the first axial flow fan 514 is an axial flow fan working, the blades push the air to flow in the same direction as the axis. The heat in the box body 1 is dissipated through the two first axial flow fans 514 and flows to the first heat dissipation hole 13 to be transferred outside the box body 1, further improving the heat dissipation effect.

[0044] Furthermore, the box body 1 also has a second heat dissipation hole 14, and the second heat dissipation hole 14 is located on the side close to the first heat dissipation hole 13.

[0045] In this embodiment, the second heat dissipation hole 14 is arranged at the rear end of the box body 1 for accelerating heat dissipation.

[0046] Furthermore, the active energy-saving and environmental protection heat dissipation system of the biochemical analyzer further includes a refrigeration air duct synthesis structure 6. The refrigeration air duct synthesis structure 6 is communicated with the box body 1 and the second heat dissipation hole 14, and is located between the air inlet device 3 and the second heat dissipation hole 14.

[0047] In this embodiment, the refrigeration air duct synthesis structure 6 is located on the large bottom plate at the upper end of the box body 1, and is used to directly dissipate the hot air of the air inlet air volume of the heat dissipation fan 32 through the second heat dissipation hole 14.

[0048] Furthermore, the refrigeration air duct synthesis structure 6 includes two second air inlet duct pipes 61, two branch air duct pipes 62, a synthesized air outlet duct pipe 63, two second axial flow fans 64 and a third axial flow fan 65. The two second air inlet duct pipes 61 are communicated with the box body 1 and are located above the air inlet direction of the heat dissipation fan 32. One end of each branch air duct pipe 62 is communicated with each second air inlet duct pipe 61, and the other end is communicated with the synthesized air outlet duct pipe 63. The synthesized air outlet duct pipe 63 is communicated with the second heat dissipation hole 14. Each second axial flow fan 64 is located between each second air inlet duct pipe 61 and each branch air duct pipe 62, and the third axial flow fan 65 is located between the synthesized air outlet duct pipe 63 and the second heat dissipation hole 14.

[0049] In this embodiment, the two second air inlet duct pipes 61 are located on the side close to the baffle 21 and face different directions, so that the heat gas at different positions can flow. The heat of the gas makes the two second air inlet duct pipes 61 and the two branch air duct pipes 62 finally merge into one synthesized air outlet duct pipe 63 and are discharged from one second heat dissipation hole 14, reducing the number of the second heat dissipation holes 14 and preventing the excessive number and over-dense arrangement of the first heat dissipation holes 13 and the second heat dissipation holes, which may cause the hot air discharged to gather at the rear end of the box body 1 and lead to the temperature rise of the box body 1. The two second axial flow fans 64 are first-level axial flow fans, and the third axial flow fan 65 is a second-level axial flow fan. When the second axial flow fan 64 works as an axial flow fan, the blades push the air to flow in the same direction as the axis. The heat in the box body 1 is dissipated through the two second axial flow fans 64 and one third axial flow fan 65 and flows to the second heat dissipation hole 14 to be transferred outside the box body 1, further improving the heat dissipation effect.

[0050] Furthermore, please refer to Figures 8 to 12 , the dust-proof device 2 further includes an adsorption assembly 23. The adsorption assembly 23 includes a first motor 231, a connecting seat 232, a second motor 233, a screw 234, a slider 235 and an adsorption pipe 236. The first motor 231 is located inside the box body 1, and the output end of the first motor 231 is in transmission connection with the connecting seat 232. The second motor 233 is located inside the connecting seat 232, and the output end of the second motor 233 is in transmission connection with the screw 234. The screw 234 is slidably connected with the slider 235 and penetrates through the slider 235. The number of the adsorption pipes 236 is multiple, and the multiple adsorption pipes 236 are fixedly connected with the slider 235 and are respectively distributed between the adjacent blades of the heat dissipation fan 32.

[0051] In this embodiment, the adsorption assembly 23 is used to adsorb and clean the ash layer on the long-term used cooling fan 32. There are multiple adsorption assemblies 23, and each adsorption assembly 23 corresponds to each cooling fan 32. The first motor 231 and the second motor 233 refer to an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. Its main function is to generate a driving torque to act on the device connected to it to rotate. The output end of the first motor 231 is in transmission connection with the connecting seat 232. Starting the first motor 231 drives the connecting seat 232 to rotate. The screw 234 has an external thread, and the slider 235 has a chute and an internal thread. The second motor 233, the screw 234, and the slider 235 form a lead screw structure. Starting the second motor 233 drives the screw 234 to rotate, and then drives the slider 235 sleeved on the screw 234 to slide along the extension direction of the screw 234. Multiple adsorption tubes 236 are fixedly connected to the slider 235, so as to drive the multiple adsorption tubes 236 to reciprocate along the extension direction of the screw 234. Specifically, when the cooling fan 32 is performing normal heat dissipation operation, the adsorption tube 236 is located on the side away from the blades of the cooling fan 32, without affecting the normal rotation of the blades of the cooling fan 32; when ash layer adsorption is required, the cooling fan 32 is controlled to stop rotating, and the second motor 233 is started to drive the screw 234 to rotate, so that the slider 235 moves along the cooling fan 32, and each adsorption tube 236 moves towards the gap between adjacent blades of the cooling fan 32. When the adsorption tube 236 reaches between adjacent blades, the second motor 233 is stopped, and the first motor 231 is started to drive the connecting seat 232 to rotate, and then the adsorption tube 236 rotates and approaches one of the adjacent blades. The adsorption tube 236 is connected to an adsorption pump outside the box body 1 through a flexible hose. The flexible hose has good flexibility, anti-twisting, and good bending performance, and does not affect moving with the movement of the adsorption tube 236. The adsorption pump is started to adsorb the ash layer on the blades of the cooling fan 32, which is convenient for cleaning, avoiding reducing the detection efficiency and increasing the cost due to long-term replacement of the cooling fan 32. After the ash layer adsorption is completed, the first motor 231 is started again to rotate and reset, so that the adsorption tube 236 is located between adjacent blades for easy withdrawal. The second motor 233 is started again to drive the screw 234 to rotate in the opposite direction, and then drives the slider 235 to move towards the side close to the connecting seat 232, so that the adsorption tube 236 withdraws from between the blades of the cooling fan 32, and the cooling fan 32 is started to continue the rotation heat dissipation process.

[0052] Further, the adsorption tube 236 includes a connecting straight tube 2361 and a bent tube 2362. The connecting straight tube 2361 is fixedly connected to the slider 235. The bent tube 2362 is integrally formed with the connecting straight tube 2361 and faces the side of the blades of the cooling fan 32.

[0053] In this embodiment, the bent tube 2362 is integrally formed with the connecting straight tube 2361, with a stable structure. The bent tube 2362 has a curvature and faces the blades of the cooling fan 32, which is beneficial for approaching the blades and facilitating the adsorption of ash layers.

[0054] Further, the adsorption tube 236 further includes a cleaning brush 2363. The cleaning brush 2363 is fixedly connected to the connecting straight tube 2361 and faces the side of the blades of the cooling fan 32.
