Abstract
Description
Technical Field
[0001] The utility model belongs to the field of medical equipment, and particularly relates to a cooling device matched with a neck and skull stimulator. Background Art
[0002] At present, the component that produces magnetic stimulation in the neck and cranial stimulator is the coil. When the coil is working, it needs to pass a large instantaneous current to generate a strong magnetic field, which causes the coil to heat up continuously. In order to reduce the working temperature of the coil, air cooling or liquid cooling is now mostly used. In the liquid cooling method, fans or semiconductor chips are often used to cool the thermal conductive medium, and the heat is transferred from the coil to the thermal conductive medium through the contact between the thermal conductive medium and the coil. Finally, the thermal conductive medium exchanges heat with the atmosphere of the working environment. However, when the working environment temperature is high, the cooling effect of the fan or semiconductor chip is not good, which affects the insulation effect of the coil and reduces the life of the coil.

The heat-conducting medium can be pure water.
[0016] The cooling device 2 includes: a condenser, a heat exchanger and a compressor. The condenser is connected to the compressor, the compressor is connected to the heat exchanger, and the heat exchanger is connected to the liquid storage tank 1 through an internal circulation pump 4. The heat exchanger is a plate heat exchanger. A cooling fan is provided on one side of the condenser. The cooling device 2 cools the heat transfer medium flowing into the heat exchanger therein and then returns it to the liquid storage tank 1.
[0017] The liquid storage tank 1 is provided with a temperature sensor, which is connected to a controller, which is connected to a first relay, which is connected to a compressor. A water flow sensor 5 is provided at the water outlet of the external circulation pump, which is connected to a controller, which is connected to a second relay, which is connected to an external circulation pump 3. The controller is a microprocessor.
[0018] Embodiment 2 of the utility model includes: a liquid storage tank for holding a heat-conducting medium, the liquid storage tank is provided with a cooling device, the liquid storage tank is provided with two liquid outlets, each liquid outlet is connected to an external circulation pump, and the liquid storage tank is also provided with two liquid return ports, the two liquid return ports are used to connect the cooling pipeline of the coil, and the heat-conducting medium after heat exchange with the coil is returned to the liquid storage tank. The heat-conducting medium can be pure water.
[0019] The cooling device includes: a condenser, a heat exchanger and a compressor. The condenser is connected to the compressor, the compressor is connected to the heat exchanger, the heat exchanger is located in the cooling tank, and the cooling tank is connected to the liquid storage tank through an internal circulation pump. The heat exchanger is a plate heat exchanger. A cooling fan is provided on one side of the condenser.
