Abstract:
A dryer includes a main body, a drying chamber provided inside the main body and configured to accommodate objects to be dried, a conveying unit configured to convey the objects to be dried, a sensor unit configured to sense information on states of the objects to be dried, and a control unit configured to control the conveying unit to move the objects to be dried based on the information sensed by the sensor unit.
Abstract:
A terminal may be provided with a magnetic regenerator unit using a magnetocaloric effect of magnetocaloric materials and a magnetic cooling system having the same. By a circular magnetic regenerator structure capable of evenly flowing heat transfer fluid and magnetic field and the flow of the heat transfer fluid being changed in the same way, and a magnetic band having a relative permeability, similar to a relative permeability of the magnetic regenerator, high efficiency of a flux generator may be obtained while reducing torque of a rotator. Power consumption for driving may be reduced due to the reduction of the cogging torque, and the magnetic band may be manufactured at a low cost by using inexpensive iron powder.
Abstract:
A magnetic cooling apparatus including a plurality of magnetic regenerators including a plurality of magnetocaloric materials to emit heat when magnetized and to absorb heat when demagnetized. The magnetic regenerators are rotatably disposed on a circumference having a predetermined radius, at least one coil is disposed on the circumference and coupled to the magnetic regenerators, and a plurality of permanent magnets is provided inside and outside the circumference to generate a magnetic field to magnetize or demagnetize the magnetic regenerators. The at least one coil interacts with the magnetic field generated by the permanent magnets to rotate the magnetic regenerators. The coil interacting with the magnetic field to magnetize or demagnetize the magnetic regenerators is coupled to the magnetic regenerators such that the magnetic regenerators reciprocate or rotate, thereby minimizing a size of the magnetic cooling apparatus, relative to the use of a motor. In addition, a member to switch a channel of a heat transfer fluid directly performs heat transfer between the heat transfer fluid and an external fluid, thereby minimizing heat loss.
