[0029] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely by embodiments with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.
[0030] Embodiment one
[0031] Figure 1is a structural schematic view of a medical heat dissipation device provided by an embodiment of the present application. The medical heat dissipation device is used in a medical device, the medical device comprising an aperture for accommodating a scanning object and electronic components, and the medical heat dissipation device comprising: a fan 10, a first sub-air duct 11 and a second sub-air duct 12 connected with the fan 10; wherein the first sub-air duct 11 and the second sub-air duct 12 are connected in parallel, the first sub-air duct 11 is used for conveying aperture ventilation airflow, and the second sub-air duct 12 is used for conveying electronic component heat dissipation airflow.
[0032] The single fan is connected with the two sub-air ducts, and the transmission of the electronic component and aperture ventilation airflow is simultaneously realized, the single fan can realize the simultaneous air supply of the two sub-air ducts, and the two sub-air ducts can meet the difference in airflow flow rate required by the electronic component and aperture ventilation.
[0033] Optionally, the device further comprises: electromagnetic valves arranged in the first sub-air duct and / or the second sub-air duct, used for controlling the airflow flow rate of the first sub-air duct and / or the second sub-air duct. The number of electromagnetic valves arranged in the first sub-air duct or the second sub-air duct is at least two.
[0034] Exemplarily, the electromagnetic valves comprise three electromagnetic valve arrays.
[0035] The three electromagnetic valve arrays can be arranged in the first sub-air duct, used for controlling the airflow flow rate of the first sub-air duct. The three electromagnetic valve arrays can also be arranged in the second sub-air duct, used for controlling the airflow flow rate of the second sub-air duct. The three electromagnetic valve arrays can also be arranged in both the first sub-air duct and the second sub-air duct, used for controlling the airflow flow rate of the first sub-air duct and the second sub-air duct. The three electromagnetic valve arrays can realize the control of four gears of airflow flow rate in the sub-air duct, each electromagnetic valve has two states of opening and closing. By closing 0, 1, 2 or 3 of the three electromagnetic valves, three gears, two gears, one gear and zero gear of the sub-air duct can be realized, the smaller the number of closed electromagnetic valves is, the greater the airflow flow rate is, and the larger the gear is, the greater the number of opened electromagnetic valves is, the smaller the airflow flow rate is, and the smaller the gear is.
[0036] In another optional embodiment of the present application, the device further comprises: a control device used for determining the number of opened electromagnetic valves according to the wind speed information input by a user.

Specifically, the temperature sensor is further configured to transmit the temperature information to the control device, and the control device is configured to upload the temperature information to the server when the temperature information is greater than a temperature threshold. When the temperature of the electronic component is less than or equal to the temperature threshold, the control device can be used to control the rotation speed of the fan to increase the air volume and reduce the temperature of the electronic component. When the temperature of the electronic component is greater than the temperature threshold, the control device can be used to upload the information to the server for remote diagnosis by an engineer.
[0038] In another optional embodiment of the present application, the control device is further configured to:

[0044] The medical heat dissipation device provided by the embodiment of the present application comprises a fan, a first branch duct connected to the fan, and a second branch duct connected to the fan. The first branch duct and the second branch duct are connected in parallel.

The same fan is used to convey the aperture ventilation air flow and the electronic component heat dissipation air flow, so that the two air paths can be controlled simultaneously, the system architecture is simplified, the cost is reduced, and the control efficiency is improved.
[0045] Embodiment two
[0046] Figure 2 A structure schematic diagram of a medical heat dissipation device is provided for the second embodiment of the present application, which provides an optional structure of the medical heat dissipation device on the basis of the above-mentioned embodiment. The medical heat dissipation device specifically comprises:
[0047] A fan 20, a first sub-air duct 21 and a second sub-air duct 22 connected with the fan 20; wherein the first sub-air duct 21 and the second sub-air duct 22 are connected in parallel, the first sub-air duct 21 is used for conveying the aperture ventilation airflow, and the second sub-air duct 22 is used for conveying the electronic component heat dissipation airflow. The device further comprises an electromagnetic valve array 23 composed of three electromagnetic valves, which is arranged in the first sub-air duct and is used for controlling the flow of the aperture ventilation airflow; a temperature sensor 24 used for detecting the temperature of the electronic component and transmitting the temperature of the electronic component to a control device 25, which can be a system computer. The control device 25 is further connected with the fan, used for obtaining the running state of the fan and adjusting the running state of the fan, and is further used for controlling the running state of the electromagnetic valve array in the first sub-air duct and uploading the running state of the fan to a server 26, so as to provide services according to the data of the server by engineers. Each electromagnetic valve in the electromagnetic valve array 23 has two states of on and off. By switching 0, 1, 2 and 3 of the three electromagnetic valves, three-speed, two-speed, one-speed and zero-speed of the aperture ventilation can be realized. The operator transmits the required air speed gear to the control device 25 through the input device, and the control device 25 controls the opening or closing of different electromagnetic valves, so as to achieve the gear required by the operator.
[0048] The medical heat dissipation device provided by the embodiment of the present application meets two different requirements simultaneously by using one fan, one power supply system and one control system. The fan is used to generate air flow for pushing the air flow in the aperture and for heat dissipation of the electronic components. The air flow generated by the fan is divided into two paths by the air distribution pipeline. The air flow in path A is used for heat dissipation of the patient aperture, and the air flow in path B is used for heat dissipation of the electronic components. The diameters of the first air distribution pipeline and the second air distribution pipeline are designed to be different, so that the distribution of the air flow in path A and path B can be realized under normal circumstances. The rotating speed of the fan can be adjusted, and the fan also has a rotating speed feedback function. The working state of the fan can be reflected by the feedback of the rotating speed of the motor of the fan. The control device can effectively predict the failure of the fan in advance by reading the rotating speed of the fan, and the working state of the fan can be reported to the server through the control device, so that the service engineer can provide active service. The temperature sensor is installed at the specified temperature sampling point of the electronic component, and is used to collect the real-time temperature of the electronic component. The temperature of the electronic component is detected by using the temperature sensor, and the real-time monitoring of the key components can be implemented, so that the working state of the key components can be effectively understood, and thus the active service can be realized. When the temperature of the electronic component is less than or equal to the temperature threshold value, the rotating speed of the fan can be adjusted by the control device to increase the air flow and reduce the temperature of the electronic component. If the temperature of the electronic component exceeds the temperature threshold value, the control device will report the service server, so that the engineer can remotely diagnose. The control device can control the fan in real time according to the temperature state of the electronic component.
[0049] The medical heat dissipation device provided by the embodiment of the present application uses the same fan to send the air flow for the aperture ventilation and the air flow for the electronic component heat dissipation, realizes the simultaneous control of the two air paths, simplifies the system architecture, reduces the cost and improves the control efficiency.
