Abstract
A fluid temperature adjusting device includes: a heater configured to heat a fluid passing through a fluid passageway; a peltier module including a plurality of peltier elements, the peltier module configured to heat or cool the fluid passing through the fluid passageway; and a controller configured to supply thermal energy from both the heater and the peltier module to the fluid and switch magnitudes of an operation amount of the heater and an operation amount of the peltier module when heating the fluid so that the fluid is kept at a target temperature.

A fluid temperature adjusting device comprising:
- a heater configured to heat a fluid passing through a fluid passageway;
- a peltier module including a plurality of peltier elements, the peltier module configured to heat or cool the fluid passing through the fluid passageway;
- and
- a controller configured to supply thermal energy from both the heater and the peltier module to the fluid and switch magnitudes of an operation amount of the heater and an operation amount of the peltier module when heating the fluid so that the fluid is kept at a target temperature.
A fluid temperature adjusting device comprising:
- a heater configured to heat a fluid passing through a fluid passageway;
- a peltier module including a plurality of peltier elements, the peltier module configured to heat or cool the fluid passing through the fluid passageway;
- and
- a controller configured to supply thermal energy from both the heater and the peltier module to the fluid and causes an operation amount of the heater to be larger than an operation amount of the peltier module with an increase in total thermal energy to be supplied to the fluid when heating the fluid so that the fluid is kept at a target temperature.
A fluid temperature adjusting device comprising:
- a heater configured to heat a fluid passing through a fluid passageway;
- a peltier module including a plurality of peltier elements, the peltier module configured to heat or cool the fluid passing through the fluid passageway;
- and
- a controller configured to supply thermal energy from both the heater and the peltier module to the fluid and change an upper limit value of the thermal energy to be supplied to the fluid based on a temperature of the fluid after heating and a temperature of a heat transfer member transferring the thermal energy from the heater and the peltier module to the fluid inside the fluid passageway when heating the fluid.
