As shown in fig. 1, an embodiment of the present invention provides a transmitting coil 100, which includes a coil body 110, and an electronic component 120 can be mounted on an outer surface of the coil body 110. The outer surface of the coil body 110 is further provided with a heat dissipation air duct 130, the heat dissipation air duct 130 comprises an air inlet duct 131 and a plurality of air outlet ducts 132, the air outlet ducts 132 are respectively communicated with the air inlet duct 131, and the air outlet ducts 132 respectively face the electronic component 120 mounted on the coil body 110. The heat dissipation air duct 130 formed on the outer surface of the coil body 110 is covered to form a heat dissipation air duct, which allows the airflow to flow along the extending direction of the heat dissipation air duct. According to the transmitting coil 100, the heat dissipation air duct 130 is arranged on the outer surface of the coil main body 110, and a heat dissipation air duct can be formed after the heat dissipation air duct is covered, so that on one hand, effective cooling of the transmitting coil 100 is realized, stable work of the transmitting coil 100 and a magnetic resonance system is further ensured, and pain caused by temperature rise in a treatment process of a patient is effectively reduced. On the other hand, the transmitting coil 100 and the magnetic resonance system utilize the existing space of the transmitting coil 100 to the maximum extent, and the heat dissipation air duct is designed in the transmitting coil 100 without adding a new air duct structural member.
As one way of achieving this, the heat dissipation duct 130 is covered with a covering structure. It can be understood that the covering structure is a structure covering the outer surface of the coil main body 110, and the covering structure is used for covering the position where the heat dissipation air duct 130 is opened on the outer surface of the coil main body 110, so as to ensure that the air flow flows along the extending direction of the heat dissipation air duct. The covering structure may be a separate structure from the transmitting coil 100, such as a tape or the like. The covering structure may also be part of the transmitting coil 100. In an embodiment of the invention, as shown in fig. 1 and fig. 2, the transmitting coil 100 further includes a covering structure, the covering structure covers the heat dissipation air duct 130 formed on the outer surface of the coil main body 110, the covering structure and the heat dissipation air duct 130 form a heat dissipation air duct, and the air flow in the heat dissipation air duct flows from the air inlet duct 131 to the air outlet duct 132. As an achievable way, the covering structure is in interference fit with the outer surface of the coil main body 110, thereby ensuring that the heat dissipation air duct has good sealing performance. Optionally, the covering structure includes a skin 140, and the skin 140 is detachably mounted on the outer surface of the coil body 110. Further, the skin 140 is elastically fitted over the outer surface of the coil body 110.
Optionally, when the electronic component 120 is mounted on the outer surface of the coil body 110, a mounting position 111 dedicated to mounting the electronic component 120 is provided on the outer surface of the coil body 110. And the number of the air outlet slots 132 in each heat dissipation air slot 130 can be designed according to the actual heat dissipation working condition. In other embodiments of the present invention, a heat dissipation air duct 130 may only include an air outlet duct 132, and the air flow input from the air inlet duct 131 is blown to the electronic component 120 with heat dissipation requirement by the air outlet duct 132.
The heat dissipation air channel 130 formed on the outer surface of the coil body 110 is a key structure for forming a heat dissipation air channel. The air outlet 132 of the heat dissipation air duct 130 faces the electronic component 120 on the outer surface of the coil body 110, and the air flowing into the air inlet 131 can be conveyed to the electronic component 120 through the air outlet 132 for heat dissipation. Alternatively, the air inlet duct 131 may communicate with the air flow duct 150 on the outer surface of the coil body 110 to guide the air flow into the heat dissipation duct, or the air inlet duct 131 communicates with the air flow duct 150 on the inner surface of the coil body 110 to guide the air flow into the heat dissipation duct.

Further, the transmitting coil 100 may have a separate air supply (e.g., a fan or air pump in communication with only the air flow line 150 of the transmitting coil 100, etc.) or may use a common air supply with other devices requiring air flow. The present embodiment does not limit the source of the airflow entering the heat dissipation duct through the airflow pipeline 150.
Effective communication between the air inlet slots 131 and the air outlet slots 132 is the key to realize heat dissipation of the transmitting coil 100. In an embodiment of the present invention, as shown in fig. 1 and 3, the heat dissipation air duct 130 further includes an air inducing section 133, the air inducing section 133 is disposed between the air inlet duct 131 and the plurality of air outlet ducts 132, the air inducing section 133 is respectively communicated with the air inlet duct 131 and the plurality of air outlet ducts 132, and the air inducing section 133 extends smoothly along the direction of the air flow. It can be understood that, in this embodiment, the air inducing section 133 is also a groove formed on the outer surface of the coil main body 110, and the air inducing section 133 extends smoothly along the direction of the air flow to sufficiently ensure smooth flow of the air flow in the heat dissipating air duct. Meanwhile, the air guiding section 133 arranged on the outer surface of the coil body 110 avoids adding an additional air guiding structure, and reduces the volume of the transmitting coil 100.
It is understood that the arrangement of the air outlet slots 132 in the heat dissipation air duct 130 should be designed according to the mounting position 111 of the electronic component 120 in the transmitting coil 100.

Further, each air outlet groove 132 is equivalent to a long and narrow groove on the outer surface of the coil main body 110, an air outlet stop block 134 is formed between the adjacent air outlet grooves 132, and the air outlet stop block 134 can play a certain role in stopping air flow.

In an embodiment of the present invention, at least some of the air outlet slots 132 are different from the air inlet slot 131, and the cross section of the air outlet slot 132 farther from the air inlet slot 131 is larger than the cross section of the air outlet slot 132 closer to the air inlet slot 131. It should be understood that the cross section described in this embodiment refers to a cross section of the air outlet groove 132 perpendicular to the extending direction (air outlet direction) of the air outlet groove. The section of the air outlet groove 132 far away from the air inlet groove 131 is larger than the section of the air outlet groove 132 near the air inlet groove 131, so that the uniform air outlet of each air outlet groove 132 is favorably maintained, and the heat dissipation performance of the transmitting coil 100 is integrally enhanced.

Further, the air flow in each heat dissipation air duct formed by each heat dissipation air duct 130 and the covering structure is the same or different, and the air flow can be adjusted according to the difference of the electronic components 120 corresponding to each heat dissipation air duct, so as to realize reasonable cooling of the transmitting coil 100.
