[Object] To provide a chiller reduced in size, cost, and energy use. [Solution] A chiller Cincludes a tank, a pump, a plurality of coolant circuitsandconfigured to cool a plurality of respective loads, and a refrigeration circuit. The plurality of coolant circuitsandand the refrigeration circuitare connected to each other via respective heat exchangersandcapable of individually controlling cooling performance. The first heat exchangerconnecting the first coolant circuitand the refrigeration circuitis configured to control a temperature of a coolant that returns from a first load Wand a second load Wto the tank. The second heat exchangerconnecting the second coolant circuitand the refrigeration circuitis configured to control a temperature of the coolant that is supplied from the tankto the second load W

Chiller

A heat exchange flow path portion is formed by alternately winding two spirally-shaped first and second heat transfer walls, with a predetermined gap interposed therebetween in the radial direction of the flow path pipe, around the outer periphery of a cylindrical flow path pipe, in which a cooling heat source is disposed in a main heat transfer flow path inside thereof. An inlet flow path and an outlet flow path for introducing compressed air into the flow path pipe and discharging compressed air from the flow path pipe are alternately formed, in the radial direction, from the gap between the heat transfer walls. Heat exchange is performed between compressed air that flows in the flow path and compressed air that flows in the flow path.
