Description

Technical Field

[0001] This utility model relates to the field of temperature control components, and in particular to a temperature control component for a CT detector module. Background Technology

[0002] During a patient scan, the X-rays generated by the X-ray tube penetrate the patient's body and are projected onto the detector module. The X-ray conversion material in the detector module converts the X-rays into electrical signals, which are then acquired and processed by the application-specific integrated circuit (ASIC). During the scan, the analog-to-digital converter on the data acquisition circuit may generate a lot of heat, which may interfere with the performance of the detector module, scintillator, etc. To ensure accurate and stable data acquisition, temperature management of the module is required, that is, to ensure that the ASIC can work effectively within a specific temperature range. Therefore, the detector module must be temperature-controllable, requiring a relatively independent space for heating and cooling control, maintaining a quantitative input and output for heat exchange with the outside world, and avoiding the influence of external heat.

[0003] However, the temperature control methods of existing CT detector module temperature control components are diverse, mainly consisting of two forms: directly attaching a PI heating film to the module bracket or using a fan to directly heat the copper tube. Both methods can control the temperature from a structural perspective, but the direct attachment of the PI heating film has problems such as inconsistent heating effects among modules and complex maintenance, while the direct fan heating of the copper tube has problems with inefficient management. Therefore, there is an urgent need to solve the thermal management problem of the detector module to ensure stable and reliable data acquisition. For this purpose, a CT detector module temperature control component is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a temperature control component for a CT detector module, which solves the problem that the temperature control methods of the existing CT detector module temperature control components are diverse, mainly including two forms: directly attaching a PI heating film to the module bracket or directly blowing a fan to heat the copper tube. Both of these methods can control the temperature from a structural point of view. However, the direct attachment of the PI heating film has the problems of inconsistent heating effect among modules and complicated maintenance, while the direct blowing of the fan to heat the copper tube has the problem of inefficient management.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a temperature control component for a CT detector module, comprising a module bracket, a fixed bracket fixedly installed in the lower middle part of the module bracket, a detector module fixedly installed in the middle part of the fixed bracket, limit steps provided on the left and right sides of the bottom of the module bracket, mounting brackets fixedly installed on the left and right sides of the fixed bracket at positions corresponding to the limit steps, fixing bolts fixedly installed on the sides of the fixed bracket, and a PI heating film fixedly installed on the top of the fixed bracket, with a thermal sensor installed inside the PI heating film.

[0006] Preferably, the module bracket has an arc-shaped structure, and the interior of the module bracket has a groove that matches the size of the fixed bracket.

[0007] Preferably, the fixed bracket forms a detachable structure with the module bracket through the cooperation between the mounting bracket and the limiting step, and the dimensions between the mounting bracket and the limiting step are mutually compatible.

[0008] Preferably, the detector module is fixedly installed at the central symmetry line of the fixed bracket.

[0009] Preferably, the PI heating film and the fixed bracket are fixed to each other, the fixed bracket is installed on the machined surface of the module bracket, and the thermal sensors are arrayed on the surface of the PI heating film.

[0010] Preferably, a fan is installed on the outside of the module bracket at the position corresponding to the fixing bolt.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] During use, the PI heating film is fixedly installed on the surface of the mounting bracket. This allows the PI heating film to heat the detector module, ensuring stable temperature operation and controlling the module's temperature. The mounting bracket provides a stable platform for the PI heating film, ensuring precise positioning. The connection between the mounting bracket and the mounting bracket is secure, maintaining a constant distance between the PI heating film and the detector module. This prevents changes in distance from affecting the heating effect and ensures uniform heating. Additionally, a thermal sensor provides feedback on the measured temperature at a nearby point, allowing for independent control by increasing the current for heat supply or reducing the current to allow for fan cooling. Furthermore, the integrated design of the PI heating film and thermal sensor facilitates easier installation and subsequent maintenance.

[0013] During use, the structure fully considers the manufacturability of the product. At the same time, the integrated PI heating film and thermal sensor components make installation and subsequent maintenance easy. The thermal management system makes full use of the PI heating film's near-field radiation and convection heating module, and uses the structure to control the distance to ensure uniform module temperature. The closed-loop control of the thermal sensor and fan ensures that the detector module temperature is constant, thereby ensuring that the X-ray signal received and processed by the detector module is stable and reliable.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figure 1-6 As shown in the figure, a temperature control component for a CT detector module includes a module bracket 1. A fixing bracket 3 is fixedly installed in the lower middle part of the module bracket 1. A detector module 4 is fixedly installed in the middle part of the fixing bracket 3. Limiting steps 5 are provided on the left and right sides of the bottom of the module bracket 1. Mounting brackets 6 are fixedly installed on the left and right sides of the fixing bracket 3 at positions corresponding to the limiting steps 5. Fixing bolts 7 are fixedly installed on the sides of the fixing bracket 3. A PI heating film 8 is fixedly installed on the top of the fixing bracket 3. A thermal sensor 2 is installed inside the PI heating film 8.

[0024] The module bracket 1 has an arc-shaped structure, and the inside of the module bracket 1 has a groove that matches the size of the fixed bracket 3. During use, the module bracket 1 provides stable support for the fixed bracket 3, and the module bracket 1 is firmly connected, ensuring that the fixed bracket 3 is in a stable position during use and ensuring accurate positioning.

[0025] The fixed bracket 3, through the cooperation between the mounting bracket 6 and the limiting step 5, forms a detachable structure with the module bracket 1. The dimensions between the mounting bracket 6 and the limiting step 5 match each other. During use, the fixed bracket 3 is engaged with the limiting steps 5 opened on both sides of the module bracket 1 by the mounting bracket 6 on both sides, thereby fixing the position of the fixed bracket 3 and ensuring that the installation position of the fixed bracket 3 remains consistent. At the same time, the limiting step 5 can limit the position of the mounting bracket 6 and prevent the mounting bracket 6 from falling out of the device.

[0026] The detector module 4 is fixedly installed at the center symmetry line of the fixed bracket 3. During use, the X-ray penetrates the patient's body and is projected onto the detector module 4. The detector module 4 then converts the X-ray into an electrical signal and performs data acquisition and processing.

[0027] The PI heating film 8 is fixed to the fixed bracket 3. The fixed bracket 3 is installed on the machined surface of the module bracket 1. The thermal sensors 2 are arrayed on the surface of the PI heating film 8. During use, the PI heating film 8 is fixedly installed on the surface of the fixed bracket 3. Therefore, the PI heating film 8 can heat the detector module 4 to ensure the temperature stability of the detector module 4 during operation, thereby controlling the temperature height of the detector module 4. Then, the fixed bracket 3 is fixedly installed on the surface of the module bracket 1. The module bracket 1 provides a stable installation platform for the fixed bracket 3. The PI heating film 8 is stably installed through the fixed bracket 3, ensuring the accurate positioning of the PI heating film 8. At the same time, the connection between the fixed bracket 3 and the module bracket 1 is stable, ensuring that the distance between the PI heating film 8 and the detector module 4 is constant and consistent, avoiding the influence of distance changes on the heating effect of the PI heating film 8 on the detector module 4, and ensuring uniform heating. In addition, the thermal sensor 2 is added to provide feedback on the measured temperature at the close distance point, and then the current is increased to increase the heat supply or the current is cut off to increase the cooling fan, so as to achieve independent control. At the same time, the PI heating film 8 and the thermal sensor 2 are integrated, making installation and subsequent maintenance operations easier.

[0028] A fan is installed on the outside of the module bracket 1 at the position corresponding to the fixing bolt 7. The fan can cool down the detector module 4 when the temperature is high, and work together with the PI heating film 8 to regulate the temperature of the detector module 4 during operation.

[0029] Working principle: First, the fixed bracket 3 is engaged with the mounting brackets 6 on both sides of the module bracket 1 through the limiting steps 5 opened on both sides, thereby fixing the position of the fixed bracket 3 and ensuring that the installation position of the fixed bracket 3 is consistent. At the same time, the limiting steps 5 can limit the position of the mounting bracket 6, preventing the mounting bracket 6 from falling out of the device. Then, the PI heating film 8 is fixedly installed on the surface of the fixed bracket 3. Therefore, the PI heating film 8 can heat the detector module 4 to ensure the temperature stability of the detector module 4 during operation, thereby controlling the temperature rise of the detector module 4. Then, the fixed bracket 3 is fixedly installed on the surface of the module bracket 1. The module bracket 1 provides a stable installation platform for the fixed bracket 3. The PI heating film 8 is fixed through the fixed bracket. 3. Stable installation ensures precise positioning of the PI heating film 8. The connection between the fixed bracket 3 and the module bracket 1 is secure, guaranteeing a constant and consistent distance between the PI heating film 8 and the detector module 4. This prevents changes in distance from affecting the heating effect of the PI heating film 8 on the detector module 4, ensuring uniform heating. Additionally, a thermal sensor 2 provides feedback on the measured temperature at a nearby point, allowing for independent control by either increasing the current to enhance heat supply or cutting off the current to increase cooling with a fan. The integrated design of the PI heating film 8 and thermal sensor 2 simplifies installation and subsequent maintenance. The module bracket 1 provides stable support to the fixed bracket 3, and the internal connections of the device are secure, ensuring the stable and accurate positioning of the fixed bracket 3 during use.
