Title: Energy conversion element
Inventor: KATORI KENJI
IPC: H02N10/00
Filed: 2020-03-14
Abstract: To provide an energy conversion element from temperature difference energy to kinetic energy having a simple structure that does not generate noise or vibration.SOLUTION: Magnetic fluid 2 is used to conduct heat between a rotatable disk-shaped thermosensitive magnetic body 1 and a part of it to which a magnetic field is applied, and heat from the outside is induced to the thermosensitive magnetic body through a permanent magnet 3 part. The magnetization of the heated thermosensitive magnetic body is reduced, and the thermosensitive magnetic body before it is heated is more attracted to the magnetic field, resulting in a rotary torque. The magnetic fluid is also used for cooling the thermosensitive magnetic body. The magnetic fluid conducts heat between a low-temperature input terminal and the thermosensitive magnetic body and cools the thermosensitive magnetic body. A lower magnetic field is applied to the low-temperature input side than to the high-temperature input side. A simple structure provides a low-vibration, low-noise, high-reliability energy conversion element.SELECTED DRAWING: Figure 1
