Description

Technical Field

[0001] The utility model relates to an electromagnetic catapult device, in particular to a heat dissipation plate component and an electromagnetic catapult device. Background Art

[0002] The electromagnetic catapult device utilizes the acting force of an electromagnetic field. Through the interaction between the magnetic field generated by an electric current on a conductor and the electric current in the conductor, a powerful thrust is generated. It is mainly applied in technical fields such as the take-off of aircraft on aircraft carriers, the launch of spacecraft, and equipment production.

[0003] Reference Publication (Announcement) Number: CN110371312B, Publication (Announcement) Date: January 3, 2023. A disclosed intermittent electromagnetic catapult device includes a track, a conductive row, and an electromagnetic module. Its catapulting power comes from electromagnetic force. However, its catapult trailer and the acceleration module that provides catapulting power are exactly the same. Therefore, after a catapult cycle is completed, the catapult trailer directly enters the end point of the catapult track to become the acceleration module, and the acceleration module at the starting point enters the catapult runway to become the catapult trailer. Through the cooperative action of the catapult trailer and the wire row, intermittent conduction of the circuit is achieved, thereby avoiding the adverse influence of electromagnetic repulsion on the acceleration of the catapult trailer. Since the catapult trailer does not need to return to the catapult starting point after the catapulting process, the moving distance and preparation time of the catapult trailer during the preparation process are reduced.

[0004] In the prior art including the above patent, when the electromagnetic catapult performs high-intensity catapulting, since a strong magnetic field is generated when an electric current passes through the electromagnetic coil, and then the carrier-based aircraft is pushed to accelerate and take off. A large amount of heat will be generated during this process. Therefore, it is necessary to dissipate heat from it to prevent material deformation caused by temperature accumulation and thus make it unusable. Summary of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0022] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.

[0023] As Figure 1-2 shown, a heat dissipation plate and an electromagnetic catapult device include symmetrically arranged installation bases 1, and the adjacent surfaces of the two installation bases 1 are recessed structures, and a heat-conducting alloy plate 2 is fixedly installed at the port of the recessed structure to form a sealed cooling oil tank 11;

[0024] A channel-shaped steel plate 6 is arranged in the cooling oil tank 11 close to the heat-conducting alloy plate 2, and a flow-through chamber 3 is formed therebetween;

[0025] The channel-shaped steel plate 6 and the inner wall of one side of the relative port of the cooling oil tank 11 are fixedly provided with transverse alloy plates 4 arranged in a linear array, and copper wires 5 arranged in a matrix are penetrated between the plurality of transverse alloy plates 4.

[0026] Specifically, in the above technology, two parallel negative electrode guide rails 100 and positive electrode guide rails 200 on the electromagnetic catapult device are respectively attached to the surface of the heat-conducting alloy plate 2, and the flying body located between the negative electrode guide rail 100 and the positive electrode guide rail 200 is fixed with a traction body at the part extending to the port between the negative electrode guide rail 100 and the positive electrode guide rail 200 and the installation base 1. The symmetrically arranged installation bases 1 are used to wrap the negative electrode guide rail 100 and the positive electrode guide rail 200, so as to prevent the heat-conducting alloy plate 2 from absorbing heat.

[0027] In the above technology, the cooling oil circulates in the cooling oil tank 11. Under high-speed operation, the heat of the negative electrode guide rail 100 and the positive electrode guide rail 200 will be transferred to the heat-conducting alloy plate 2. The high-speed flowing cooling oil is attracted by the channel-shaped steel plate 6, the transverse alloy plate 4 and the copper wire 5, and generates low temperature to exchange heat with the heat exchanged by the heat-conducting alloy plate 2, and the flowing cooling oil takes away the temperature.

[0028] It should be noted that the transportation and cooling of the above cooling oil are all well-known technical common sense, so no detailed description will be given.

[0029] As a further embodiment provided by the present utility model, the radius of the copper wire 5 is 1 cm - 3 cm.

[0030] Specifically, the copper wire 5 with a large radius can quickly absorb the low temperature of the cooling oil, thereby creating a low-temperature environment away from the heat-conducting alloy plate 2. When the temperature of the heat-conducting alloy plate 2 rises, due to the temperature difference, the oil body flows and heat exchange occurs.

[0031] As another embodiment further provided by the present utility model, the number of channel steel plates 3 is several and they are arranged in a linear array.

[0032] Specifically, a pinch effect is formed between two adjacent channel steel plates 3. When the oil body with temperature difference flows, the flow rate is accelerated and the heat exchange efficiency is improved.

[0033] As another embodiment further provided by the present utility model, the side wall of the channel steel plate 3 is provided with oil passing holes that penetrate completely and are arranged in a matrix.

[0034] Furthermore, an aluminum alloy cold plate 7 is centrally arranged in the flow-through cabin 3. Positive triangular blocks 71 whose tops do not contact the inner wall of the flow-through cabin 3 are respectively arranged on the outer walls of the opposite sides of the aluminum alloy cold plate 7.

[0035] Specifically, the channel steel plate 3 is used for separation, so that there is an obvious temperature difference between the area where the copper wire 5 is located and the area close to the heat-conducting alloy plate 2, thereby accelerating the flow and improving the heat exchange efficiency.

[0036] As another embodiment further provided by the present utility model, a conical flow guiding hole member 8 fixed on the aluminum alloy cold plate 7 is arranged between four adjacent positive triangular blocks 71. The narrow opening of the conical flow guiding hole member 8 faces the heat-conducting alloy plate 2.

[0037] Specifically, the conical flow guiding hole member 8 forms a narrow hole effect. When the oil body with temperature difference flows, the flow rate is accelerated and the heat exchange efficiency is improved.

[0038] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
