The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying fig. 1-8.
The present embodiment provides a CT apparatus, as shown in fig. 1 to 2, including a heat dissipation device for a CT detector. The heat dissipation device for the CT detector comprises a shell 11, a support 1 arranged in the shell 11, a rotary table 12, a closed detector box 2, an internal heat dissipation structure and an external heat dissipation structure, wherein the rotary table 12 is rotatably connected to the support 1. The holder 1 is disposed inside the housing 11.
The internal heat dissipation structure includes an airflow source disposed inside the detector box 2 that is capable of promoting airflow within the detector box 2 to transfer heat generated by the detector modules 22 to the interior walls of the detector box 2.
The external heat dissipation structure comprises an annular airflow channel arranged in the support 1, the detector box 2 is positioned in the airflow channel, and an air inlet 8 and an air outlet 7 which are communicated with the airflow channel are arranged on the shell 11.
In the embodiment, the airflow source is arranged in the detector box 2, and the airflow source promotes the air flow in the detector box 2, so that the heat generated by the detector module 22 is transferred to the outside of the detector through the wall of the detector box 2, and then is taken away through the airflow channel, and the combination of the internal heat dissipation structure and the external heat dissipation structure improves the heat dissipation efficiency and ensures that the heat is not accumulated on the detector module 22; in addition, detector box 2 is enclosed construction, can prevent dust, dampproofing, lightproof and prevent that the X ray from revealing.
In order to enable the heat inside the detector box 2 to be rapidly transferred to the outside of the detector box 2, optionally, the detector box 2 is made of aluminum alloy, and the heat conduction efficiency of the aluminum alloy is high.
As shown in fig. 3 and 4, the airflow source is a plurality of internal fans 21, the plurality of internal fans 21 are disposed in the detector box 2, and the air outlet direction is toward the detector module 22. The heat dissipation plate 23 is mounted on the support metal plate of the detector module 22, and the internal fan 21 is located on the side of the heat dissipation plate 23. Since the internal fan 21 is disposed inside the closed detector box 2, noise is small.
In order to promote the exchange of hot air flow inside the bracket 1 and cold air flow outside, and improve the heat dissipation efficiency, optionally, two air outlets 7 are respectively arranged on two sides of the upper part of the shell 11; both sides of the lower part of the shell 11 are respectively provided with an air inlet 8. In order to allow the gas to reach the gas outlet 7 and the gas inlet 8 of the housing 11, the parts of the support 1 corresponding to the gas inlet 8 and the gas outlet 7 of the housing 11 are likewise provided with the gas inlet 8 and the gas outlet 7, respectively.
Further, the shell 11 comprises a cylinder 5 located at the center of the shell, the cylinder 5 penetrates through the center of the rotary table 12, the detector box 2 is connected to the rotary table 12 and located between the cylinder 5 and the inner wall of the support 1, and an airflow channel is formed by the outer wall of the cylinder 5, the rotary table 12 at one end of the cylinder 5, the side wall of the shell 11 at the other end of the cylinder 5 and the inner wall of the support 1. The detector box 2 is a semi-arc structure arranged along the periphery of the rotary table 12, a mounting plate 4 is arranged on one side of the rotary table 12 opposite to the detector box 2, the ray source 6 is mounted on the mounting plate 4, and two ends of the mounting plate 4 are in butt joint with two ends of the detector box 2. Specifically, both ends of the cylinder 5 penetrate both opposite sides of the housing 11. The cross-sections of both ends of the detector box 2 are sequentially reduced towards the ends thereof, so as to facilitate the circulation of gas. When the turntable 12 rotates, the rotation of the turntable 12 generates a rotation airflow to dissipate heat from the detector box 2, and as shown in fig. 5, the direction of the arrow in the figure is the airflow direction.
In order to accelerate the gas circulation when the rotary table 12 stops rotating, the heat dissipation effect is better, when the rotary table 12 stops rotating, one gas inlet 8 corresponds to the middle position of the detector box 2, one end part of the detector box 2 corresponds to the other gas inlet 8, and the other end part of the detector box 2 corresponds to one gas outlet 7.
Further, the external heat dissipation structure further comprises a wind gathering structure, and the wind gathering structure is used for gathering the airflow entering the bracket 1 from the air inlet 8 and then blowing the airflow to the airflow channel. The heat of the detector box 2 can be taken away quickly through the arrangement of the wind gathering structure, and is transferred through the airflow channel.
As shown in fig. 1, 2 and 6, the wind-gathering structure includes a wind-gathering plate 3 and a wind-gathering cover 10, the wind-gathering plate 3 is installed in the bracket 1 and is located at the air inlet 8; the wind-collecting cover 10 is installed on the wind-collecting plate 3, and the outlet of the wind-collecting cover 10 is rectangular. The outlet of the air collecting cover 10 is rectangular, so that the air flow is in a slender shape and is blown to the air flow passage, and the heat dissipation area of the detector box 2 can be increased. Optionally, an external air inlet fan is disposed at the inlet of the air collecting cover 10, and an external air outlet fan is disposed at the air outlet 7. As shown in fig. 7, when the direction of the arrow in the figure is the gas flow direction and the turntable 12 stops rotating, the external heat radiation air flow can be formed by the external air inlet fan and the external air outlet fan.
As shown in fig. 8, stage 1 is a temperature curve when the internal heat dissipation structure and the external heat dissipation structure reach a basic thermal steady state in both working stages; stage 2 is the process of gradually reducing the external heat dissipation air volume; stage 3 is a basic thermal steady state process of the system again after the external heat dissipation is completely stopped; stage 4 is a thermally stable process when both internal and external heat dissipation stops working.
The temperature change curves of the temperature A of the detector module, the temperature B of the air flow in the detector box and the temperature C of the detector box are compared to obtain that:
the comparison between the stage 1 and the stage 4 shows that the temperature B of the air flow in the whole detector box is obviously lower when the internal heat dissipation structure works compared with the condition that the heat is not dissipated inside and outside, and the comparison between the internal heat dissipation structure and the detector box 2 shows that the heat accumulation is not easy to occur in the working gap stage.
Three curves for stage 3 and stage 4 compare: the temperature a of the detector module rises significantly, while the temperature B of the airflow in the detector box and the temperature C of the detector box do not rise significantly, indicating that the internal heat dissipation structure can quickly carry heat to the wall of the detector box 2. The internal cycle is stopped and the heat of the detector module 23 in phase 4 cannot be transferred quickly and the heat accumulates in large quantities. This illustrates that the internal heat dissipation structure of the present invention has the function of rapidly transferring heat from the detector module 23.
The above figure compares stage 1 with stage 2 and stage 3: after the external heat dissipation system stops, the temperature B of the airflow in the detector box integrally rises, and the external heat dissipation structure has the function of quickly transferring away the heat of the detected outer wall.
