Referring to fig. 1 and 2, an embodiment of the present invention provides a probe apparatus 100. The detection apparatus 100 is applied to an imaging device. In this embodiment, an imaging apparatus is described taking a CT (computed tomography) apparatus as an example. The detection device 100 of the invention can ensure the temperature of the detection device 100 to be evenly distributed, avoid generating temperature gradient, ensure the response of the detection device 100 to be consistent and stable, further improve the image imaging quality and facilitate the diagnosis of doctors.
Referring to fig. 1, 4 and 5, an embodiment of the present invention provides a probe apparatus 100. The probe apparatus 100 includes a housing assembly, a plurality of probe assemblies 110, a plurality of cooling lines 140, and a water diversion assembly 130. The housing assembly has a mounting chamber. A plurality of probe assemblies 110 are spaced apart within the mounting chamber. The cooling pipes 140 are filled with cooling fluid, and each cooling pipe 140 is disposed on one of the detecting elements 110. The water diversion assembly 130 is disposed on the housing assembly. The water diversion assembly 130 comprises a plurality of mutually independent and non-communicated sub water diversion members, each sub water diversion member is provided with a main liquid inlet, a main liquid outlet, a plurality of branch liquid outlets and a plurality of branch liquid outlets, the plurality of branch liquid outlets are respectively connected with inlets of a plurality of cooling pipelines 140 corresponding to the areas, and the plurality of branch liquid outlets are connected with outlets of a plurality of cooling pipelines 140 corresponding to the areas.
The shell assembly can play a role in containing, supporting and fixing, the detection device 100 is fixed on a rotary support of the CT system through the shell assembly, and all parts of the detection device 100 are arranged in the shell assembly, so that dust can be prevented from falling onto all parts of the detection device 100, and the service performance of all parts is ensured; meanwhile, the shell assembly can also play a role in protection, so that each part of the detection device 100 is prevented from being touched in use, and the reliability is improved. Preferably, the housing assembly has a mounting chamber. The various components of the detector assembly 100 are mounted in a mounting chamber of the housing assembly.
Further, a plurality of detection assemblies 110 are disposed in parallel in the installation chamber. That is, a certain distance exists between two adjacent detection assemblies 110, and a flow channel can be formed between two adjacent detection assemblies 110. It will be appreciated that the detection assemblies 110 generate a large amount of heat when receiving and processing X-ray information, and this heat can flow in the flow channels of two adjacent detection assemblies 110 and be absorbed by the cooling circuit 140. Therefore, the temperature in the mounting chamber can be balanced, the overall temperature of the detection device 100 is balanced, the temperature gradient is eliminated, the response stability of the detection device 100 is ensured, the image imaging quality is ensured, and the diagnosis of doctors is facilitated.
The cooling line 140 has a cooling fluid flowing therein. The cooling fluid in the cooling circuit 140 may absorb heat generated by the operation of the detection assembly 110 to rapidly lower the temperature of the detection assembly 110. Moreover, the cooling liquid in the cooling pipeline 140 flows, so that the heat generated by the detection assembly 110 can be absorbed timely and continuously, and the continuous cooling of the detection assembly 110 is realized. Because each detection assembly 110 can be cooled by the corresponding cooling pipeline 140, the temperature of each detection assembly 110 can be ensured to be basically consistent, and further, the overall temperature of the detection device 100 is balanced, and the temperature gradient is eliminated. Optionally, the cooling liquid in the cooling pipeline 140 may be water, oil, or other cooling media.
The water diversion assembly 130 is disposed on the housing assembly, and is connected to the cooling pipeline 140 of the detection assembly 110, for inputting and outputting cooling liquid to the cooling pipeline 140. The water diversion assembly 130 is used for respectively delivering the low-temperature cooling liquid to the cooling pipelines 140 of the detection assemblies 110, and meanwhile, recovering the cooling liquid absorbing heat in the cooling pipelines 140. After the cooling liquid is conveyed through the water diversion assembly 130, the temperature of each detection assembly 110 can be reduced, and the temperature of each detection assembly 110 is basically consistent, so that the overall temperature of the detection device 100 is balanced, and the temperature gradient is avoided. Furthermore, the temperature of each probe assembly 110 is reduced, thereby equalizing the temperature in the mounting chamber of the housing assembly.
The water diversion assembly 130 comprises a plurality of mutually independent and non-communicated sub water diversion members, each sub water diversion member is provided with a main liquid inlet, a main liquid outlet, a plurality of branch liquid inlets and a plurality of branch liquid outlets, the plurality of branch liquid outlets are respectively connected with inlets 141 of a plurality of cooling pipelines 140 corresponding to the areas, and the plurality of branch liquid inlets are connected with outlets 142 of a plurality of cooling pipelines 140 corresponding to the areas. That is, the plurality of detection assemblies 110 are divided into several regions according to the arrangement direction, and each region is respectively connected with the plurality of detection assemblies 110 in the corresponding region through a sub-water-dividing member, so that the output and the recovery of the cooling liquid are realized. Thus, the shunting effect of the cooling liquid can be ensured, and the cooling effect of the detection assembly 110 can be further ensured. As can be understood, the total liquid inlet is connected with the total liquid outlet and a total cold source of the external cooling liquid, and is used for realizing the conveying and the recovery of the cooling liquid.
It can be understood that the sub water diversion members are independent and not communicated with each other, that is, each sub water diversion member is provided with a water storage chamber, and the water storage chambers of the sub water diversion members are not communicated with each other and are independent from each other. Therefore, the cooling liquid absorbing heat can be prevented from entering other sub-water dividing pieces to influence the cooling effect. Optionally, each sub-dividing member may be of an integral structure. Furthermore, the ports of the sub-water diversion member are named according to the flowing direction of the cooling liquid in the sub-water diversion member, for example, the port for flowing in the cooling liquid is a liquid inlet, and the port for flowing out the cooling liquid is a liquid outlet. Further, the total liquid inlet is used for conveying the cooling liquid generated by the external cold source to the sub-water diversion members, and the sub-water diversion members respectively convey the low-temperature cooling liquid to the cooling pipelines 140 through the respective liquid outlet ports. The cooling liquid after absorbing the heat gets into sub-branch water spare through dividing the liquid inlet to finally send out sub-branch water spare through total liquid outlet.
Moreover, since each sub-water diversion member can only cool the detection assemblies 110 in the corresponding region, the number of the detection assemblies 110 which need to be cooled in the corresponding region can be selected according to the cooling capacity of the cooling liquid, such as 5 to 15, and the like, and of course, the number can be smaller or larger. This ensures that the temperature of the cooling fluid in each cooling circuit 140 is substantially uniform, such that the temperature of each probe assembly 110 is uniform to eliminate temperature gradients. The positions of the plurality of detection modules 110 are divided into edge positions and middle regions along the arrangement direction of the detection modules 110, at least one sub-water-diversion member is respectively arranged on the detection modules 110 at the edge positions and the middle positions correspondingly, and cooling liquid is conveyed through the corresponding sub-water-diversion members to cool the detection modules 110. In this way, the center sub-water-diversion member can cool each detection assembly 110 in its area by itself, and the edge sub-water-diversion member is not required to supply the cooling liquid to the center detection assembly 110.
It can be understood that if the edge sub-water diversion member delivers the cooling liquid to the middle region detection assembly 110, the temperature of the cooling liquid in the cooling pipeline 140 at the middle region is higher than that of the cooling liquid in the edge sub-water diversion member 140 due to the limitation of the delivery distance, which may result in a high middle temperature of the detection device 100 and a temperature gradient problem.
Therefore, the detection device 100 of the present invention uses the plurality of sub-water diversion members to deliver the cooling liquid to the cooling pipelines 140 of the plurality of detection assemblies 110 in the corresponding regions, so as to realize independent cooling of the detection assemblies 110 in each region, and the cooling liquid at the edge position is not required to enter the middle region for cooling, thereby effectively solving the problem of corresponding inconsistency of the detectors caused by high middle temperature and large temperature gradient of the current detectors. Therefore, the temperature of the detection assembly 110 in the middle area can be reduced, the temperature of the detection assembly 110 in the middle area is basically consistent with the temperature of the detection assembly 110 in the edge position, the temperature balanced distribution of the detection device is guaranteed, the temperature gradient is avoided, the response of the detection device is guaranteed to be consistent and stable, the image imaging quality is improved, and the diagnosis of a doctor is facilitated.
Alternatively, as shown in fig. 1, the housing assembly includes a lower housing 120 and an upper housing (not shown), the plurality of sensing elements 110 are disposed in parallel on an inner wall of the lower housing 120, and the upper housing is mounted on the lower housing 120 and forms the mounting chamber. Of course, in other embodiments of the present invention, the upper case may be interchanged with the lower case 120, i.e., the plurality of detection units 110 are disposed in parallel on the inner wall of the upper case. In general, the lower case 120 is installed in the scanning system, and the heat of the detecting element 110 can be transferred to the lower case 120 of the housing element, so that the heat of the detecting element 110 can be conducted out through the lower case 120, thereby further reducing the temperature of the detecting element 110.
In one embodiment, the central region of the diversion assembly 130 has at least one sub-diversion member along the direction of arrangement of the plurality of detection assemblies 110. That is, the water diversion assembly 130 has at least one sub-diversion member in the middle region along the arc arrangement direction of the plurality of detection assemblies 110 in fig. 1. In this embodiment, the middle region of the water diversion member 130 has a sub water diversion member. When the arc size of the water diversion assembly 130 is long, the middle region of the water diversion assembly 130 may have two, three or more sub water diversion pieces to ensure the cooling effect of the detection assembly 110.
In an embodiment, the water diversion assembly 130 further includes a plurality of flow regulating components, and the plurality of flow regulating components are disposed on the plurality of sub water diversion pieces and used for regulating the flow rate of the cooling liquid in the liquid diversion outlet. The flow rate adjusting part may adjust the flow rate of the cooling liquid in the sub-water dividing member to adjust the temperature of the sensing assembly 110 in each region.
Optionally, a flow rate adjusting component is correspondingly arranged at each liquid outlet. The flow rate adjustment part may adjust the flow rate of the cooling liquid in the cooling line according to the heat dissipation amount of the probe assembly 100 at the corresponding region. Meanwhile, the flow rate adjusting part can also adjust the flow rate of the cooling liquid according to the cold quantity of the cooling liquid in the corresponding cooling pipeline 140. Therefore, the temperature of each detection assembly 110 can be ensured to be consistent, the overall temperature of the detection device 100 is uniform, the temperature gradient is avoided, the response stability of the detection device 100 is ensured, the image imaging quality is ensured, and the diagnosis of doctors is facilitated. Illustratively, the flow regulating member is a flow valve.
Of course, in other embodiments of the present invention, in each of the sub water diversion members, the aperture of the liquid outlet at the position close to the total liquid inlet is smaller than or equal to the aperture of the liquid outlet at the position far from the total liquid inlet. Because the cooling liquid flows into the sub-water diversion parts from the main liquid inlet, certain cold energy loss exists in the process that the cooling liquid flows to each sub-liquid outlet. After changing the aperture of the liquid-separating port, the flow rate of the cooling liquid can be changed. To ensure the cooling temperature of each probe assembly 110 is uniform, the flow rate may be adjusted by varying the aperture of the tap to adjust the cooling temperature of the probe assembly 100. For example, the aperture of the liquid separation outlet is large, the flow direction of the cooling liquid is correspondingly large, the aperture of the liquid separation outlet is small, and the flow direction of the cooling liquid is correspondingly small. Thus, after the aperture of the liquid outlet at the position close to the total liquid inlet is smaller than the aperture of the liquid outlet at the position far from the total liquid inlet, the flow rate of the cooling liquid in the cooling pipeline 140 close to the total liquid inlet can be properly smaller than the flow rate of the cooling liquid in the cooling pipeline 140 far from the total liquid inlet, so that the temperatures of the detection assemblies 110 are consistent, and the overall temperature of the detection device 100 is uniform.
In this embodiment, the water diversion assembly 130 includes a first sub-water diversion member 131, a second sub-water diversion member 132 and a third sub-water diversion member 133 that are independent and not communicated with each other, and the second sub-water diversion member 132 is located between the first sub-water diversion member 131 and the third sub-water diversion member 133. The first sub water diversion member 131, the second sub water diversion member 132, and the third sub water diversion member 133 are respectively connected to the cooling pipes 140 of the corresponding regions.

This allows for three zones to be distributed to supply the cooling fluid to ensure that the temperature of each of the probe assemblies 110 is consistent, resulting in a uniform temperature across the probe apparatus 100.
Specifically, the first sub water diversion member 131 has a first main liquid inlet 1311, a first main liquid outlet 1312, a plurality of first branch liquid inlets 1314 and a plurality of first branch liquid outlets 1313. The first main liquid inlet port 1311 is connected to the first main liquid outlet port 1312 and an external cool source. The plurality of first branch liquid outlets 1313 are connected to the inlets 141 of the cooling pipes 140 of the detection modules 110 corresponding to the left side regions, and the plurality of first branch liquid outlets 1314 are connected to the outlets 142 of the cooling pipes 140 of the detection modules 110 corresponding to the left side regions. The cooling liquid of the external cold source enters the first sub water diversion member 131 through the first main liquid inlet 1311, after being diverted by the first sub water diversion member 131, the cooling liquid respectively enters the cooling pipeline 140 through the corresponding first water diversion outlet 1313, and after absorbing heat, the cooling pipeline 140 enters the first sub water diversion member 131 through the first water diversion inlet 1314 and then is sent out through the first main liquid outlet 1312 of the first sub water diversion member 131.
Similarly, the second water diversion member 132 has a second total liquid inlet 1321, a second total liquid outlet 1322, a plurality of second liquid diversion inlets 1324 and a plurality of second liquid diversion outlets 1323. The second total liquid inlet port 1321 is connected to the second total liquid outlet port 1322 and an external cold source. The plurality of second branch liquid outlets 1323 are connected to the inlets 141 of the cooling lines 140 of the probe assemblies 110 corresponding to the left side regions, and the plurality of second branch liquid inlets 1324 are connected to the outlets 142 of the cooling lines 140 of the probe assemblies 110 corresponding to the left side regions. The third sub-water diversion member 133 has a third main liquid inlet port 1331, a third main liquid outlet port 1332, a plurality of third liquid diversion ports 1334 and a plurality of third liquid diversion ports 1333. The third total liquid inlet port 1331 is connected to the third total liquid outlet port 1332 and an external cold source. The plurality of third branch liquid outlets 1333 are connected to the inlets 141 of the cooling pipes 140 of the detection modules 110 corresponding to the left side region, and the plurality of third branch liquid inlets 1334 are connected to the outlets 142 of the cooling pipes 140 of the detection modules 110 corresponding to the left side region. Since the flowing manner of the cooling liquid in the second sub-water diversion member 132 and the third sub-water diversion member 133 is the same as that of the first sub-water diversion member 131, it is not repeated herein.
In one embodiment, the inlet 141 and the outlet 142 of the cooling pipeline 140 are disposed on the same side, each sub-water distributing member includes a water distributing plate, and the main liquid inlet, the main liquid outlet, the plurality of sub-liquid distributing ports and the plurality of sub-liquid outlet ports are formed on the water distributing plate.

That is, when the inlet 141 and the outlet 142 of the cooling pipeline 140 are disposed on the same side, the output and the recovery of the cooling fluid can be realized by one water diversion assembly 130. When the inlet 141 and the outlet 142 of the cooling pipeline 140 are disposed on opposite sides, it is necessary to input the cooling liquid into the cooling pipeline 140 through one water diversion assembly 130, and to recover the cooling liquid absorbing heat in the cooling pipeline 140 through the other water diversion assembly 130. In this embodiment, the inlet 141 and the outlet 142 of the cooling pipeline 140 are disposed on the same side, and the output and the recovery of the cooling liquid are realized through one water diversion assembly 130.
Referring to fig. 1-3, in one embodiment, the detecting assembly 110 includes an electronic component 111 and a bracket 112. The electronic component 111 may heat up. The holder 112 is used to support the electronic component 111. The cooling pipe 140 is provided to a middle region of the bracket 112 in a height direction of the bracket 112, and is the same as an extending direction of the bracket 112. The cooling pipe 140 is filled with a cooling fluid, and can absorb heat of the holder 112 and the electronic component 111 and discharge the absorbed heat.
The electronic component 111 can detect the X-rays passing through the human body, and process the electrical signals of the detected X-rays and transmit the processed signals to an image reconstruction system of the CT apparatus for image reconstruction. The electronic component 111 generates a large amount of heat during operation. If the heat of the electronic component 111 is accumulated too much, the accuracy of the electronic component 111 for detecting X-rays and processing signals will be affected, and the quality of image reconstruction will be affected.
Accordingly, the probe assembly 110 of the present invention provides a cooling circuit 140 on the support 112, the cooling circuit 140 having a cooling fluid flowing therein. The cooling liquid in the cooling pipeline 140 can absorb the heat generated by the electronic component 111 and the heat on the bracket 112, so as to rapidly lower the temperature of the electronic component 111 and the bracket 112, and thus lower the temperature of the whole detecting assembly 110. Moreover, the cooling liquid in the cooling pipeline 140 flows, and can timely and continuously absorb the heat generated by the electronic component 111, so as to reduce the temperature of the electronic component 111 and the bracket 112, and realize the continuous cooling of the detection assembly 110. Therefore, the accuracy of detecting the X-rays and the accuracy of processing signals by the electronic element 111 can be ensured, and the image reconstruction quality is further ensured.
Also, the cooling pipe 140 is located at a middle region of the bracket 112 in the height direction. The cooling circuit 140 can effectively absorb heat from the detection assembly 110 to lower the temperature of various parts of the detection assembly 110.
The support 112 can support the electronic component 111 disposed thereon, and the support 112 can also perform heat transferring and dissipating functions, so that the support 112 can transfer heat of the electronic component 111 to the cooling pipeline 140 and absorb the heat through the cooling liquid of the cooling pipeline 140. Therefore, the temperature of the detection assembly 100 can be reduced, the overall temperature of the detection device 100 is balanced, and the temperature gradient is avoided. Optionally, the bracket 112 is made of a metal material. The bracket 112 made of metal facilitates the transfer of heat. The heat generated by the electronic component 111 can be absorbed by the cooling liquid in the cooling pipeline 140 through the bracket 112, so as to improve the cooling effect of the detection assembly 110. Of course, in other embodiments of the present invention, the bracket 112 may also be made of a thermally conductive non-metallic material.
Optionally, the electronic component 111 includes a detector unit, a signal transmission board, and a signal processing board. The support 112 supports the detector unit, the signal transmission board, and the signal processing board. The detector unit detects X-rays penetrating through a human body, the signal transmission plate is electrically connected to the detector unit and the signal processing plate, and the signal transmission plate can transmit electric signals of the X-rays detected by the detector unit to the signal processing plate, and transmits the electric signals to the image reconstruction system after being processed by the signal processing plate for image reconstruction.
In one embodiment, the bracket 112 has a mounting slot therein, and the cooling circuit 140 is located in the mounting slot. The cooling pipe 140 is mounted to the mounting groove in an embedded, welded or adhered manner. Therefore, the contact area between the cooling pipeline 140 and the support 112 can be increased, the heat absorption effect of the cooling liquid in the cooling pipeline 140 is improved, the temperature of the electronic element 111 and the temperature of the support 112 are effectively reduced, the heat dissipation of each position of the detection assembly 110 is uniform, the generation of temperature gradient is avoided, the temperature of the detection assembly 110 is uniformly distributed, the response of the detection device 100 is ensured to be consistent and stable, the image imaging quality is improved, and the diagnosis of doctors is facilitated.
Further, the surface of the cooling pipe 140 exposed after being mounted in the mounting groove is coplanar with the surface of the bracket 112. That is, the cooling circuit 140 is completely embedded in the bracket 112. Therefore, the contact area between the cooling pipeline 140 and the bracket 112 can be further increased, the heat absorption effect of the cooling liquid in the cooling pipeline 140 is improved, the temperature of the electronic element 111 and the bracket 112 is effectively reduced, the heat dissipation of each position of the detection assembly 110 is uniform, and the temperature gradient is avoided.
Generally, after a mounting groove is formed in the bracket 112, the cooling pipe 140 is placed in the mounting groove, and then the cooling pipe 140 is fixed by melting solder. Of course, in other embodiments of the present invention, the cooling circuit 140 may be fixed to the bracket 112 by a clip or the like.
In one embodiment, the cooling circuit 140 extends in the same direction as the probe assembly 110. That is to say, the cooling pipeline 140 increases the contact area with the detection assembly 110, and can cool down the whole detection assembly 110, so as to ensure the cooling effect of the detection assembly 110 and reduce the temperature of the detection assembly 110.
In one embodiment, the cooling tube 140 is bent at least once. In this way, the area of the cooling pipeline 140 arranged on the support 112 can be increased, so that the area for the circulation of the cooling liquid is increased, the heat exchange effect is improved, the cooling effect of the detection assembly 110 is ensured, the temperature of the detection assembly 110 is reduced, the heat dissipation uniformity of each position of the detection assembly 110 is ensured, the generation of temperature gradient is avoided, and the temperature of the detection assembly 110 is uniformly distributed. It will be appreciated that the number of bends of the cooling circuit 140 may be selected according to the heat dissipation requirements of the probe assembly 110. For example, when the heat dissipation requirement of the detection assembly 110 is small, the cooling pipeline 140 may be bent once, for example, in a U-shape. In this embodiment, the cooling pipe 140 is bent three times.
In one embodiment, there is a distance between the liquid inlet and the liquid outlet, and the liquid outlet is disposed close to the electronic component 111 and the liquid inlet is disposed far from the electronic component 111 in the height direction of the bracket 112. That is, in the height direction of the rack 112, the inlet 141 of the cooling duct 140 is disposed close to the electronic component 111, the outlet 142 of the cooling duct 140 is disposed away from the electronic component 111, and there is a space between the inlet 141 and the outlet 142. As shown in fig. 4, when the electronic component 111 of the detecting assembly 110 is disposed below the bracket 112, the inlet 141 of the cooling pipeline 140 is located below the outlet 142 of the cooling pipeline 140. Since the electronic component 111 is located below the support 112, the temperature below the support 112 is higher than the temperature above the support 112. The cooling liquid of the cooling pipeline 140 has a low temperature when entering from the inlet 141, and can quickly take away heat after flowing through a region with a high temperature, so as to ensure the cooling effect of the detection assembly 110, further ensure the accuracy of detecting X rays by the electronic element 111 and the accuracy of processing signals, and improve the quality of image reconstruction.
