A crosslinked fluororesin-coated rotor manufacturing method is a method for manufacturing an annular outer rotor of an internal gear pump including the outer rotor, and an inner rotor, a side surfaces of the outer rotor being coated with a crosslinked fluororesin, an inner peripheral surface of the outer rotor not being coated with the crosslinked fluororesin, the method including: using an outer masking jig for covering the inner peripheral surface in a state where the side surfaces of the outer rotor are exposed; coating the outer rotor with an uncrosslinked fluororesin in a state where the outer masking jig is mounted to the outer rotor; and then irradiating the fluororesin with radiation in a state where the outer masking jig is removed from the outer rotor, to crosslink the fluororesin.

Crosslinked fluororesin-coated rotor manufacturing method

A heat transfer device includes a bag and a working fluid. The bag includes a first sheet and a second sheet with edges that are sealed together. The working fluid is enclosed in the bag. The working fluid changes a phase thereof between gas and liquid. The bag includes a vaporizing portion in which the liquid-phase working fluid is vaporized and a condensing portion in which the gas-phase working fluid is condensed. The bag includes a two-phase flow channel in which liquid-gas two-phase slug flow including the liquid-phase working fluid and the gas-phase working fluid occurs from the vaporizing portion to the condensing portion. The two-phase flow channel is provided in an internal space of the bag.

Heat transfer device and energy storage module

The heat transfer device includes a sealed bag, a working fluid, and a contact component. The working fluid is enclosed in the bag. The contact component includes a first contact portion and a second contact portion that are separated from each other via a spacer. A left edge portion of the bag is disposed between the first contact portion and the second contact portion. The left edge portion contacts the first contact portion and the second contact portion when the bag expands due to vaporization of the working fluid.

Heat transfer device, heat transfer system, and energy storage module

A power storage module includes: a plurality of power storage elements; a plurality of cooling members each of which has a coolant and a sealing body hermetically sealing the coolant, is stacked on the power storage element, and is configured to form a bulging portion by deformation of the sealing body caused by evaporation of the coolant at an extension portion extending in a region not overlapping the power storage element; and a heat dissipation member that receives heat of the plurality of cooling members and dissipates the heat to an outside. The heat dissipation member has a spacer portion that is disposed between the adjacent extension portions of the plurality of cooling members and is configured to abut with the bulging portion.

Power storage module

A power storage module includes a cooling member that has a coolant and a sealing body hermetically sealing the coolant; a power storage element that is stacked on the cooling members; and a heat transfer plate that is stacked on the power storage elements with the cooling members therebetween. The sealing body is configured to form a bulging portion deformed by evaporation of the coolant in a region not overlapping the power storage element. The heat transfer plate has a folded portion with which the bulging portion is configured to abut.
