Description

Technical Field

[0001] This invention relates to the field of conventional magnetic resonance electromagnetic coils, and in particular to a G-type clamp for electromagnetic coils. Background Technology

[0002] Currently, the final step in the production process of electromagnetic coils for conventional magnetic resonance imaging (MRI) equipment is to bond the cooling aluminum plate to the coil. The conventional process is to fix it around the outside with studs and nuts after bonding. However, this can lead to deformation of the cooling aluminum plate, resulting in a hollow part between the coil and the cooling aluminum plate and poor bonding. In some areas, gaps may also appear between the coil and the cooling aluminum plate due to poor flowability of the thermally conductive adhesive. Both of these situations can lead to poor heat dissipation of the electromagnetic coil, increased resistance, overheating of the electromagnetic coil, and increased power consumption. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a G-type clamp for electromagnetic coils that can reduce the hollow area between the cooling aluminum plate and the coil and increase the contact area.

[0004] To solve the above-mentioned technical problems, the present invention provides a G-type clamp for electromagnetic coils, including a support part and a clamping part. The support part is a C-type support frame, and the clamping part includes a long rod stud, a pressure plate connected to the long rod stud, and a pressure plate connected to the bottom of the C-type support frame. The long rod stud of the clamping part is threadedly connected to the top of the C-type support frame and passes through the threaded hole at the top of the C-type support frame.

[0005] Preferably, the long stud is provided with a rotary wrench at the top.

[0006] Preferably, the pressure plate connected to the long rod stud and the pressure plate connected to the bottom of the C-shaped support frame are both threadedly connected to the long rod stud and the bottom of the C-shaped support frame.

[0007] Preferably, the pressure plate connected to the long rod stud and the pressure plate connected to the bottom of the C-shaped support frame are available in various sizes, and different sizes of pressure plates can be selected as needed.

[0008] Preferably, the pressure plate connected to the long rod stud and the pressure plate connected to the bottom of the C-shaped support frame are made of epoxy resin board.

[0009] The present invention employs a structure in which a pressure plate applies balanced pressure to the cooling aluminum plate, thereby reducing the hollow area between the cooling aluminum plate and the coil, increasing the contact area, and thus improving the problem of poor heat dissipation and heat generation of the electromagnetic coil, and reducing power consumption.

[0010] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0011] Figure 1This is a front view of the G-type clamp for electromagnetic coils of this utility model.

[0012] Figure 2 This is a schematic diagram of an embodiment of the G-type clamp for electromagnetic coils of this utility model.

[0013] Among them, 1-C-type support frame, 2-long rod stud, 3-rotary wrench, 4-pressure plate connected to the long rod stud, 5-pressure plate connected to the bottom of the C-type support frame, 6-cooling aluminum plate, 7-coil. Detailed Implementation

[0014] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 1 , Figure 2 As shown, the G-type clamp for electromagnetic coils includes a support part and a clamping part. The support part is a C-type support frame 1. The clamping part includes a long rod stud 2, a pressure plate 4 connected to the long rod stud, and a pressure plate 5 connected to the bottom of the C-type support frame. The long rod stud 2 of the clamping part is threadedly connected to the top of the C-type support frame 1 and passes through the threaded hole at the top of the C-type support frame 1.

[0016] The top of the long-rod stud 2 is equipped with a rotating wrench 3, which can adjust the pressure plate according to the thickness of the electromagnetic coil and the required pressure. The pressure plates 4 / 5 are made of epoxy resin board, which can reduce the damage to the cooling aluminum plate caused by the hardness of the pressure plate itself during clamping. Multiple plates are provided, and different sizes can be selected as needed to ensure that the cooling aluminum plate is firmly bonded to the coil, the force is evenly distributed, and the hollow area between the cooling aluminum plate and the coil is reduced.

[0017] During processing, the cooling aluminum plate and the coil are bonded together with thermally conductive adhesive and placed on a wooden support. By observing the flow of the thermally conductive adhesive, a pressure plate of appropriate size 4 / 5 is selected. The G-type clamp for the electromagnetic coil is evenly and symmetrically arranged along the electromagnetic coil. The pressure plate 5, which is connected to the bottom of the C-type support frame, is placed below the aluminum plate 6 in the cold zone at the bottom of the electromagnetic coil. The pressure plate 4, which is connected to the long rod stud, is placed above the cooling aluminum plate 6 at the top of the electromagnetic coil. The rotary wrench 3 is adjusted to make the pressure plate press tightly against the cooling aluminum plates 6 at the top and bottom of the electromagnetic coil, so that it bears uniform pressure with a large contact area. This ensures a tight bond between the cooling aluminum plate 6 and the coil 7, reduces the probability of deformation of the cooling aluminum plate and the hollow area between it and the coil, and increases the contact area.

[0018] Therefore, the present invention uses a G-type clamp for electromagnetic coils with the above-mentioned structure. By applying balanced pressure to the cooling aluminum plate through the pressure plate, the hollow area between the cooling aluminum plate and the coil can be reduced, the contact area can be increased, thereby improving the problem of poor heat dissipation and heat generation of the electromagnetic coil and reducing power consumption.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
