Abstract
Description
Technical Field
[0001] This utility model relates to pulsed magnetic therapy equipment, and in particular to a circulating heat dissipation system on a pulsed magnetic therapy equipment, belonging to the field of electromechanical equipment technology. Background Technology
[0002] When pulsed magnetic stimulation (PMS) devices are in operation, the built-in coils generate a high-intensity magnetic field when subjected to high-current, high-voltage pulses. The pulse frequencies typically range from 0.1 to 100 Hz, with peak currents in the thousands of amperes and voltages in the thousands of volts. This repetitive high voltage and high current acting on the coils, even with short stimulation times, leads to a cumulative increase in coil temperature, increasing coil impedance and further raising the coil temperature, potentially burning the patient or damaging the equipment. Therefore, the coils must be cooled during use. Currently, cooling methods for magnetic stimulation coils generally include natural cooling, fan cooling, and liquid cooling. Fan cooling is inefficient and noisy. Liquid cooling of magnetic stimulation coils usually uses coolant (most commonly water), which can lead to consumption or leakage over time, requiring timely replenishment. Otherwise, the cooling effect will weaken. Existing cooling devices have simple liquid level detection mechanisms, and cannot respond promptly to coolant leaks. When coolant leaks onto other electrical components, it can cause short circuits and equipment malfunctions; leaks onto other mechanical parts can accelerate component aging. Safety needs improvement. For example, Chinese patent CN219110652U discloses a cooling and refrigeration device for transcranial magnetic stimulation coils, which suffers from the aforementioned problems. This device connects the inlet and outlet water pipes of the refrigeration tank to the stimulation coil, lacks a separate refrigerant injection port, and cannot directly inject water. Furthermore, each refrigeration tank in this device is equipped with two liquid level sensors, which can only detect high and low liquid levels. However, they cannot detect subtle changes in liquid level in a timely manner. Tilting the equipment or tank can easily trigger the liquid level sensors, failing to accurately reflect the refrigerant content and making it inconvenient for users to monitor the equipment's condition. Summary of the Invention
[0003] The purpose of this invention is to provide a circulating heat dissipation system for a pulsed magnetic therapy device.
[0004] To achieve the purpose of this utility model, the following technical solution is adopted: a circulating heat dissipation system for a pulse magnetic therapy device, comprising a heat dissipation water tank, a water pump, a return water pipe, and an outlet water pipe. The outlet water pipe extends into the heat dissipation water tank near the bottom and is connected to the inlet of the water pump. The water outlet of the water pump is connected to the inlet of the coil, and the water outlet of the coil is connected to the heat dissipation water tank through the return water pipe. The heat dissipation water tank is fixedly mounted on a weighing sensor, and a water quality detection sensor is installed inside the heat dissipation water tank. Both the weighing sensor and the water quality detection sensor are connected to a controller.
[0005] Furthermore, the return water pipe enters from the top or upper side of the radiator tank, and an inlet sedimentation tray is provided at the outlet of the return water pipe. At least two support rods are provided under the inlet sedimentation tray, and the support rods are fixedly connected to the radiator tank. The return water from the return water pipe returns to the inlet tray and overflows into the radiator tank.
[0006] Furthermore, a drain valve is installed at the bottom of the radiator, and a water injection pipe is also installed on the radiator, with a water injection valve connected to the water injection pipe.
[0007] The positive and beneficial technical effects of this utility model are as follows: This system can conveniently monitor the amount of coolant, whether there is leakage, and the water quality of coolant, so as to ensure the cooling effect and normal operation of the equipment. The specific implementation method will be described in detail. Attached Figure Description
[0008] Figure 1 This is a schematic diagram of the present invention. Detailed Implementation
[0009] To more fully explain the implementation of this utility model, implementation examples are provided. These implementation examples are merely illustrative of this utility model and do not limit its scope.
[0010] The present invention will be further explained in detail with reference to the accompanying drawings, in which the following references are made: 1: cooling water tank; 2: water pump; 3: water outlet of the water pump; 4: coil; 5: water outlet pipe; 6: water return pipe; 7: water inlet sedimentation tray; 8: water injection valve; 9: water quality detection sensor; 10: drain valve; 11: weighing sensor; 12: support rod.
[0011] As shown in the attached figure, a circulating heat dissipation system for a pulsed magnetic therapy device includes a heat dissipation tank 1, a water pump 2, a return water pipe 6, and an outlet water pipe 5. The outlet water pipe 5 extends into the heat dissipation tank near the bottom and is connected to the inlet of the water pump. The water outlet 3 of the water pump is connected to the inlet of the coil 4. The water outlet of the coil is connected to the heat dissipation tank through the return water pipe 6. The return water pipe enters from the top or upper side of the heat dissipation tank. An inlet sedimentation tray 17 is provided at the outlet of the return water pipe. At least two support rods 12 are provided under the inlet sedimentation tray and are fixedly connected to the heat dissipation tank. The return water from the return water pipe returns to the inlet tray and overflows into the heat dissipation tank. After the inlet water returns to the inlet sedimentation tray, some metal impurities settle to the bottom of the inlet tray, preventing these impurities from flowing back into the heat dissipation tank and then entering the circulation pipeline, causing wear and damage to the equipment and components and affecting the heat dissipation effect. The inlet sedimentation tray can be removed and cleaned when the machine is stopped by opening the top cover of the heat dissipation tank. A drain valve 10 is installed at the bottom of the radiator to drain water. A water injection pipe is also installed on the radiator, and a water injection valve 8 is connected to the water injection pipe to inject water into the radiator.
[0012] The cooling water tank is fixedly mounted on the weighing sensor 11, and a water quality sensor 9 is installed inside the tank. Both the weighing sensor and the water quality sensor are connected to the controller. After the water pump starts and circulation begins, the total weight of the cooling water tank should remain within a stable range. If the weight suddenly increases, it indicates a leak in the system. If the weighing sensor detects that the weight gradually decreases during long-term use, it indicates normal system consumption. Once the weight drops to a certain level, water is added through the water inlet valve until the set weight is reached, at which point water replenishment stops. The water quality sensor detects the quality of the circulating water and reminds users to change the water promptly. The water quality sensor is an existing product; for example, an existing digital turbidity sensor or intelligent optical turbidity electrode can be used.
[0013] The cooling water tank in this application is prior art. For example, existing water tanks with walls made of aluminum alloy plates with heat sinks can be called cooling water tanks. When used in equipment, an exhaust fan can be used to dissipate heat from the cooling water tank. After the water is cooled in the cooling water tank, it is pumped to cool the coil and then returned to the cooling tank through a return pipe for further cooling. This cycle is repeated to complete the cooling of the coil.
[0014] After a detailed description of the embodiments of this utility model, those skilled in the art will clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent applications. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the scope of the technical solution of this utility model, and this utility model is not limited to the embodiments of the examples given in the specification.
