Economical and practical embedded freezing and cold storage fresh-keeping and preservation low-intensity magnetic field modularization device

Abstract

The invention discloses an economical and practical embedded freezing and cold storage fresh-keeping and preservation low-intensity magnetic field modularization device which can be applied to refrigerators, intelligent cabinets, wine cabinets, warehouse logistics equipment and the like. The device comprises a coil frame, a magnet exciting coil and a control circuit, the magnet exciting coil is arranged in the coil frame so as to generate a steady low-intensity magnetic field or a pulse steady low-intensity magnetic field; and the control circuit is connected with the magnet exciting coil and used for adjusting the magnetic field intensity of the steady low-intensity magnetic field or the pulse steady low-intensity magnetic field and the magnetic field frequency and the duty ratio of the pulse steady low-intensity magnetic field. According to the device, a small-size coil frame and a small-size wire diameter are adopted, so that the ratio range of the weight of the device to the effective storage volume of embedded equipment is 0.05-0.5 kg/L, the unit volume energy consumption of the embedded equipment is 0.03-5.0 W/L, important factors such as weight, magnetic field intensity and frequency, coil heat dissipation, magnetic field duty ratio and the like are balanced, high-quality and low-energy-consumption freezing and refrigeration of food, medical supplies, agricultural product raw materials, fresh flowers, plant seeds and the like by the magnetic field are kept to the maximum extent.

Description

technical field [0001] The invention relates to an economical and practical embedded freeze-refrigeration fresh-keeping and preservation weak magnetic field modular device. The embedded weak magnetic field modular device of the present invention can be applied to embedded equipment such as refrigerators, smart cabinets, wine cabinets, storage and logistics, and belongs to the new technology field of refrigerators, smart cabinets, wine cabinets and other equipment. Background technique [0002] With the improvement of living standards, traditional refrigerators, freezers, cabinets or storage and logistics equipment can no longer meet people's needs for high-quality refrigeration and dry matter storage of food and agricultural products. Studies have shown that water molecules, organic compounds and biological macromolecules are all diamagnetic materials, which can be magnetized and oriented under an external magnetic field. For water, more hydrogen bonds are formed between wa...

Problems solved by technology

Specifically, if the heating energy consumption of the magnetic field device is too large, the local temperature rise will increase the internal temperature fluctuation of the refrigerator, which will put forward higher requirements for the cooling and heat dissipation devices of refrigerators and other equipment, and increase energy consumption, and then It cannot be used commercially; if the additional weight of the magnetic field device is too large in order to reduce the heating power, which will cause the position of the center of gravity of the equipment embedded in the magnetic field device to change, the equipment will not be able to withstand the uncertain turbulence during long-distance transportation, making the product stable The performance is poor, and the increase in weight will also lead to an increase in cost, so it has no
