A cooler allows easy attachment and detachment of a battery. The cooler includes a main container including a refrigeration compartment, an evaporator on the main container, a compressor and a condenser adjacent to the main container, and at least one battery mount to receive a power tool battery in a detachable manner. The at least one battery mount is adjacent to the main container and above the compressor and the condenser.

CELL SYSTEM

A cell system includes: a stacked-type cell module (100) having a plurality of lithium ion unit cells (1) being stacked and having through holes (3a, 3b) formed therein; a gas supply part (31); a cooling liquid supply part (32); a temperature sensor (35); and a control part (36) that controls switching between a normal control mode and a high-temperature control mode based on a signal from the temperature sensor (35). In the normal control mode, the control part (36) controls the gas supply part (31) to supply a gas to the through holes (3a, 3b), and at the same time, controls the cooling liquid supply part (32) to stop supply of a cooling liquid, and in the high-temperature control mode, the control part (36) controls the cooling liquid supply part (32) to supply the cooling liquid to the through holes (3a, 3b) to which the gas is supplied, and at the same time, controls the gas supply part (31) to stop supply of the gas. According to this cell system, the increase in temperature of the cell is suppressed while having a simple configuration with a reduced formation region of through holes provided in a lithium ion cell.

DEVICE TEMPERATURE REGULATOR

In a device temperature regulator, an evaporator cools a target device by a latent heat of evaporation of a working fluid that absorbs heat from the target device and is evaporated. A first condenser includes a first heat exchange passage that condenses the working fluid evaporated in the evaporator by a heat exchange with an outside first medium. A second condenser includes a second heat exchange passage that condenses the working fluid evaporated in the evaporator by a heat exchange with an outside second medium. A gas-phase passage causes the working fluid evaporated in the evaporator to flow to the first condenser and the second condenser. Furthermore, a first liquid-phase passage causes the working fluid condensed in the first condenser to flow to the evaporator, and a second liquid-phase passage causes the working fluid condensed in the second condenser to flow to the evaporator.
