DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] like Figure 1-3 As shown, a first aspect of an embodiment of the present application provides a heat dissipation assembly 100 of a CT detector. The heat dissipation assembly 100 of the CT detector includes a housing 110 , a heating element 120 , and a first air guide 130 .

[0028] The housing 110 is used to accommodate the heating element 120, the first air guide 130 and other components in the CT detector. In order to improve the strength of the housing 110, the material of the housing 110 can be metal, so as to improve the strength and thermal conductivity. The housing 110 has a accommodating space 110a, an air inlet 110b and an air outlet 110c. The air inlet 110b and the air outlet 110c are both connected to the accommodating space 110a. The air inlet 110b, the second space 110e and the air outlet 110c form a heat dissipation channel. Air can enter the accommodating space 110a from the air inlet 110b and then be discharged from the air outlet 110c, so as to achieve the purpose of exchanging heat. Optionally, the air inlet 110b is arranged at the lower part of the housing, and the air outlet 110c is arranged at the upper part of the housing, so as to form a natural circulation air duct.

[0029] The heating element 120 is a component that generates heat in the CT detector. The heating element 120 can be a tube assembly. The heating element 120 is arranged in the accommodation space 110a of the housing 110. The heating element 120 will continue to generate heat when working. If the heat is not removed in time, the life of the CT detector may be affected.

[0030] The first air guide 130 is disposed in the accommodating space 110a of the housing 110, and divides the accommodating space 110a into a first space 110d and a second space 110e. Since the first air guide 130 is disposed in the housing 110, the first air guide 130 can enhance the strength of the housing 110. The first space 110d can be used to set some parts of the CT detector, especially parts that do not generate heat or generate less heat. The heating element 120 is located in the second space 110e, and the air inlet 110b and the air outlet 110c are both connected to the second space 110e. The material of the first air guide 130 can be metal, for example, to enhance strength and thermal conductivity.

[0031] It is understandable that the CT detector has multiple parts, and the position of the heating element 120 is often not able to be changed at will due to the layout of other parts. Similarly, the opening positions of the air inlet 110b and the air outlet 110c on the housing 110 also have certain limitations. Therefore, after the air enters the accommodation space 110a, most of the air may not pass through the heating element 120, but pass through other parts and then be discharged from the air outlet 110c, thereby affecting the heat dissipation efficiency of the heating element 120.

[0032] The embodiment of the present application is provided with the first air guide 130. Due to the separation effect of the first air guide 130, after the air enters the accommodation space 110a from the air inlet 110b, it is difficult to enter the first space 110d, and most of the air enters the second space 110e, so that the air can flow through the heating element 120 with a greater probability to improve the heat dissipation efficiency. To a certain extent, the closer the first air guide 130 is to the heating element 120, the larger the volume of the first space 110d, and the smaller the volume of the second space 110e, the more air flows through the heating element 120, and the higher the heat dissipation efficiency.

[0033] like Figure 2-3 As shown, in some exemplary embodiments, the first air guide 130 includes a main body plate 132, a first folded edge 133 and a second folded edge 134. The first folded edge 133 is connected to the main body plate 132 and is arranged at an angle with the main body plate 132, for example, the first folded edge 133 is arranged perpendicular to the main body plate 132. The second folded edge 134 is connected to the main body plate 132 and is arranged at an angle with the main body plate 132, for example, the second folded edge 134 is arranged perpendicular to the main body plate 132. The first folded edge 133 and the second folded edge 134 can improve the connection strength between the first air guide 130 and the housing 110.

[0034] The first folded edge 133 is disposed on the housing 110 corresponding to the air inlet 110 b , that is, the first folded edge 133 is disposed close to the air inlet 110 b , so as to better guide the air to flow in a preset direction.

[0035] The second folded edge 134 is arranged opposite to the first folded edge 133, and the second folded edge 134 is arranged on the housing 110 corresponding to the air outlet 110c, so as to guide the air to flow out from the air outlet 110c. The bottom of the first space 110d is closed by the first folded edge 133, the top of the first space 110d is closed by the second folded edge 134, one side of the first space 110 is closed by the housing 110, and the other side opposite thereto is closed by the main body plate 132, so that the isolation between the first space 110d and the second space 110e is better, and more air flows into the second space 110e.

[0036] like Figure 4-6As shown, in some exemplary embodiments, the heat dissipation assembly 100 of the CT detector also includes a second air guide 140, and the second air guide 140 is arranged in the second space 110e corresponding to the air inlet 110b, and the flow cross-sectional area corresponding to the end of the second air guide 140 away from the heating element 120 is greater than the flow cross-sectional area corresponding to the end of the second air guide 140 close to the heating element 120. The material of the second air guide 140 can be plastic, so that the second air guide 140 can be manufactured into a desired shape through an injection molding process, with low cost and light weight. When the second air guide 140 is made of the same material as the first air guide 130, the second air guide 140 and the first air guide 130 can be separated or integrally formed. When the second air guide 140 and the first air guide 130 are made of different materials, the second air guide 140 and the first air guide 130 can be separated. The shape of the second air guide 140 can be a flat plate, an arc plate, or a combination of a flat plate and an arc plate. By setting the angle of the second air guide 140 relative to the housing 110, the gap between the second air guide 140 and the housing 110 is changed, that is, the flow cross-sectional area is changed. As the flow cross-sectional area is reduced, when the air flow rate remains unchanged, the air flow rate will increase, so that the air speed flowing through the heating element 120 is faster, thereby taking away more heat and improving the heat dissipation effect.

[0037] It should be noted that the second air guide 140 can guide the air to the bottom of the heating element 120. The air first cools the bottom of the heating element 120 and then rises to the upper part of the heating element 120 to cool it, thereby cooling the entire heating element 120 and avoiding uneven cooling.

[0038] In some alternative embodiments, the second air guide 140 may also be replaced by a funnel-shaped air guide tube, with the end with a larger diameter being away from the heating element 120 and the end with a smaller diameter being close to the heating element 120, which can also achieve the effect of changing the flow cross-sectional area. Alternatively, the second air guide 140 is a flat plate, and the portion of the housing 110 corresponding to the second air guide 140 is an arc-shaped plate, and by changing the shape of the housing 110, the gap between the second air guide 140 and the housing 110 is changed, that is, the flow cross-sectional area is changed.

[0039] like Figure 5 and Figure 8As shown, in some exemplary embodiments, the surface of the second air guide 140 for guiding air is provided with a plurality of mutually parallel ribs 141, and an air guide channel is formed between each two adjacent ribs 141. The air guide channel has an air guide function, which can make the air flow through the second air guide 140 with less resistance and less loss, and the plurality of air guide channels can also comb the airflow to reduce the generation of turbulence. At the same time, the ribs 141 can also increase the strength of the second air guide 140 and improve the service life of the second air guide 140. Optionally, the ribs 141 extend in the direction of the heating element.

[0040] like Figure 5-6 As shown, in some exemplary embodiments, the second air guide 140 includes a mounting section 142 , a connecting section 143 and an extending section 144 .

[0041] The mounting section 142 is connected to the first air guide 130, and the mounting section 142 and the first air guide 130 can be connected by welding, clamping, bonding, screwing, etc. The mounting section 142 is arranged close to the air inlet 110b to produce a higher guiding effect on the air of the air inlet 110b.

[0042] The connecting section 143 is connected to the mounting section 142. The surface of the connecting section 143 for guiding wind is a curved surface. When air flows through the curved surface, a Coanda effect will be generated, that is, the air will flow along the curved surface, thereby having a better guiding effect on the air and reducing the flow resistance of the air.

[0043] The extension section 144 is connected to an end of the connection section 143 away from the installation section 142 . The air from the air inlet 110 b passes through the installation section 142 and is guided to the extension section 144 by the connection section 143 .

[0044] The flow cross-sectional area corresponding to the connection between the connecting section 143 and the mounting section 142 is greater than the flow cross-sectional area corresponding to the connection between the connecting section 143 and the extension section 144. That is, the first air guide 130 changes the flow cross-sectional area through the connecting section 143, and the flow cross-sectional area is the cross-sectional area between the connecting section 143 and the bottom of the housing 110.

[0045] like Figure 5-6As shown, in some exemplary embodiments, the extension section 144 is closer to the heating element 120 than the first air guide 130. It is understandable that, also limited by the layout of other components in the CT detector, it is difficult to set the first air guide 130 close to the heating element 120. The second air guide 140 does not need to separate the accommodating cavity, so the structure of the second air guide 140 is simpler and smaller than the first air guide 130, so it is easier to be set close to the heating element 120. Since the extension section 144 is closer to the heating element 120 than the first air guide 130, that is, the extension section 144 is closer to the heating element 120 than the main plate 132, the extension section 144 can guide the air to a position closer to the heating element 120, thereby guiding the air to the heating element 120 to the greatest extent, thereby improving the heat dissipation efficiency.

[0046] like Figure 3 and Figure 6 As shown, in some exemplary embodiments, the heat dissipation assembly 100 of the CT detector further includes a heat sink 150, which is disposed on the heating element 120. The heat sink 150 may be a heat dissipation fin, so that the contact area with the air can be increased to improve the heat dissipation effect. The heat sink 150 and the heating element 120 may be connected by screwing, bonding, pressing, etc. A thermal conductive coating may be applied between the heat sink 150 and the heating element 120 to improve the thermal conductivity.

[0047] In some exemplary embodiments, the heat dissipation assembly 100 of the CT detector further includes a heat dissipation fan, which is used to accelerate air flow, thereby improving heat dissipation efficiency. The number of heat dissipation fans can be one or more, and the type of heat dissipation fan can be axial flow, centrifugal, etc., which is not limited here.

[0048] The heat dissipation fan is disposed in the housing 110 and corresponds to the air outlet 110c. For example, the heat dissipation fan is disposed at the air outlet 110c of the housing 110. The heat dissipation fan draws air in the second space 110e to drive the air to flow from the air inlet 110b to the air outlet 110c.

[0049] Alternatively, the heat dissipation fan is disposed in the housing 110 and corresponds to the air inlet 110b. For example, the heat dissipation fan is disposed at the air inlet 110b of the housing 110, and the heat dissipation fan blows toward the second space 110e to drive the air to flow from the air inlet 110b to the air outlet 110c.

[0050] Alternatively, a heat dissipation fan is disposed at the heating element 120 , and the heat dissipation fan accelerates the heat dissipation of the heating element 120 .

[0051] like Figure 2 and Figure 7As shown, in some exemplary embodiments, the mounting section 142 is provided with a first connection portion 1421, and the first air guide 130 is provided with a second connection portion 131 that cooperates with the first connection portion 1421. The first connection portion 1421 can be exemplarily a buckle, and the second connection portion 131 can be exemplarily a slot.

[0052] The housing 110 is provided with a third connection portion 111, and the first folded edge 133 is provided with a fourth connection portion 1331 that cooperates with the third connection portion 111. The third connection portion 111 may be a slot, and the fourth connection portion 1331 may be a buckle piece.

[0053] In a second aspect, an embodiment of the present application provides a CT detector, which includes a heat dissipation assembly 100 and a controller of the CT detector. The controller is connected to a heating element 120 to control the operation of the heating element 120 .

[0054] CT detectors can emit X-rays that pass through the human body and convert the received light signals into electrical signals. CT detectors can collect data after X-rays pass through human tissues, providing a basis for reconstructing image information of human tissues. The stability of the output signal of the CT detector is closely related to the temperature, so ensuring the temperature stability of the CT detector is the key to ensuring the performance of the CT detector.
