Abstract
A supercooling release device according to one aspect of the present disclosure releases a supercooled state of a heat storage material. The supercooling release device includes a first member and a second member capable of being brought into contact with each other. The first member and the second member each include a metal. While a load is continuously applied to at least one of the first member and the second member to bring at least a portion of a surface of the first member and at least a portion of a surface of the second member into close contact with each other, the supercooled state is maintained. When the supercooled state is to be released, the supercooling release device reduces the above load.
Claims20
A supercooling release device that releases a supercooled state of a heat storage material, the supercooling release device comprising:
- a first member and a second member capable of being brought into contact with each other;
- and
- a guide member configured to control displacement of the first member and the second member in a direction orthogonal to a direction in which the load is applied, wherein:
- the first member and the second member each include a metal,
- the guide member includes a cylinder,
- the cylinder houses the first member and the second member in an opening portion,
- the cylinder includes a through hole, through which the heat storage material enters into the opening portion,
- while a load is continuously applied to at least one of the first member and the second member to bring at least a portion of a surface of the first member and at least a portion of a surface of the second member into contact with each other, the supercooled state of the heat storage material is maintained such that the heat storage material is maintained in a liquid phase at a temperature below a melting point of the heat storage material, and
- when the supercooled state is to be released to solidify the heat storage material, the load is reduced.
A heat storage device comprising:
- a supercooling release device;
- a heat storage material including at least one selected from the group consisting of a salt hydrate, a sugar alcohol, and a clathrate hydrate;
- and
- a container housing the heat storage material, wherein:
- the supercooling release device comprises:
- a first member and a second member capable of being brought into contact with each other;
- and
- a guide member configured to control displacement of the first member and the second member in a direction orthogonal to a direction in which the load is applied,
- the first member and the second member each include a metal,
- the guide member includes a cylinder,
- the cylinder houses the first member and the second member in an opening portion,
- the cylinder includes a through hole, through which the heat storage material enters into the opening portion,
- the supercooling release device is attached to the container so that the through hole of the cylinder contacts the heat storage material,
- while a load is continuously applied to at least one of the first member and the second member to bring at least a portion of a surface of the first member and at least a portion of a surface of the second member into contact with each other, the supercooled state of the heat storage material is maintained such that the heat storage material is maintained in a liquid phase at a temperature below a melting point of the heat storage material, and
- when the supercooled state is to be released to solidify the heat storage material, the load is reduced.
A supercooling release device that releases a supercooled state of a heat storage material, the supercooling release device comprising:
- a first member and a second member capable of being brought into contact with each other;
- a guide member configured to control displacement of the first member and the second member in a direction orthogonal to a direction in which the load is applied;
- and
- a load application member configured to apply, to at least one of the first member and the second member, a load for bringing at least a portion of a surface of the first member and at least a portion of a surface of the second member into contact with each other, wherein:
- the guide member includes a cylinder,
- the cylinder houses the first member and the second member in an opening portion,
- the cylinder includes a through hole, through which the heat storage material enters into the opening portion,
- the load application member is configured to continuously apply the load to maintain the supercooled state of the heat storage material such that the heat storage material is maintained in a liquid phase at a temperature below a melting point of the heat storage material, and
- the load application member is configured to reduce the load to release the supercooled state to solidify the heat storage material, and
- the first member and the second member each include a metal, and are each plate-shaped.
