  • Patent Document 1 Conventionally, a heat pipe described in Patent Document 1 is known.
  • a heat transfer fluid is sealed in a liquid-tight manner inside a pipe made of a metal material.
  • the pipe is required to have strength in order to enclose the heat transfer fluid. This is because when the heat transfer fluid receives heat from the heating element and evaporates, the volume of the heat transfer fluid increases and the pressure in the pipe increases. Encapsulating a heat transfer fluid in a pipe in a liquid-tight manner and using a pipe having a relatively high strength has led to an increase in manufacturing cost.
  • the present invention has been completed based on the above circumstances, and an object of the present invention is to provide a cooling member with reduced manufacturing cost and a power storage module using the same.
  • the present invention is a cooling member, wherein a liquid-tight enclosure in which a sheet member is joined at at least one junction, a refrigerant sealed in the enclosure, and at least one junction among the junctions And a heat sink that is liquid-tightly joined to the inner surface of the enclosure, and that has a heat absorbing portion located in the enclosure and a heat radiating portion located outside the enclosure.
  • the inner volume of the enclosure increases due to the deformation of the sheet member. This reduces the pressure in the enclosure. As a result, the pressure resistance in the encapsulated body can be reduced as compared with the case where the cooling member is formed by a metal container whose inner volume does not change. Thereby, the manufacturing cost of a cooling member can be reduced.
  • the sheet member preferably includes a metal sheet.
  • the metal sheet since the metal sheet has high thermal conductivity, it is possible to quickly move the heat inside the enclosure to the outside of the enclosure and dissipate the heat to the external space.
  • the sheet member is preferably a laminate film in which a synthetic resin film is laminated on the surface of the metal sheet.
  • the encapsulant can be formed by a simple technique of heat-sealing the laminate film.
  • the side edge of the enclosure is such that the side edge of the sheet member is bent inward of the enclosure and expands so as to increase the internal volume of the enclosure when the refrigerant evaporates. It is preferable that an expanded portion to be opened is formed.
  • the expanding portion expands and deforms, whereby the pressure in the encapsulated body can be further reduced.
  • the manufacturing cost of a cooling member can be reduced further.
  • an absorption sheet for absorbing the refrigerant is disposed in the enclosure.
  • the refrigerant since the refrigerant is absorbed and held in the absorbent sheet, the refrigerant can be uniformly arranged in the region where the absorbent sheet is arranged. Thereby, it can suppress that a nonuniformity arises in the cooling efficiency of a cooling member.

  • a groove extending in a direction approaching the joint portion joined to the heat sink among the joint portions is formed in the heat absorbing portion of the heat sink.
  • the evaporated refrigerant flows through the groove formed in the separator or the heat radiating plate, thereby approaching the joint portion connected to the heat radiating plate.
  • the vapor of the refrigerant approaching the joint part joined to the heat sink contacts the heat absorbing part of the heat sink and transfers heat to the heat sink.
  • the heat transmitted to the heat radiating plate is quickly conducted from the heat absorbing portion to the heat radiating portion, and is dissipated from the heat radiating portion to the outside of the cooling member.
  • the evaporated refrigerant flows through the groove and then transfers heat to the heat radiating plate in the vicinity of the joint joined to the heat radiating plate. After conduction, heat can be quickly dissipated to the outside of the cooling member.

  • the heat generated in the power storage element is absorbed by the cooling member that contacts a part of the outer surface of the power storage element. Since the cooling member is formed in a liquid-tight manner and the refrigerant is sealed in the cooling member formed in a liquid-tight manner, it is not necessary to configure the casing of the power storage module in a liquid-tight manner. As a result, the manufacturing cost of the storage element can be reduced.
  • a slit is formed in the casing, and the heat radiating portion is inserted through the slit and exposed to the outside of the casing.
