Heat storage device of vehicle
First Claim
1. A heat storage device of a vehicle, comprising:
- an insulation container in which an outlet and an inlet are formed;
a coolant passage disposed to penetrate the inlet and the outlet, wherein opposing ends of the coolant passage are fluidly connected to coolant outlets of a vehicle engine;
a heat exchanger that includes a fin formed on the coolant passage inside the insulation container;
a phase change material that is charged in the insulation container to exchange heat with coolant flowing in the coolant passage through the fin;
a phase change material temperature sensor that detects a temperature of the phase change material within the insulation container;
a pressure sensor that detects a pressure inside the insulation container;
an engine coolant temperature sensor that detects a temperature of coolant circulating in the engine; and
a control portion that circulates the coolant through the coolant passage according to a driving condition of the engine and the coolant temperature such that the coolant exchanges heat with the phase change material;
wherein a bypass line is fluidly connected to the coolant passage to bypass the insulation container, and an inlet valve and an outlet valve are disposed to divert coolant passage around the insulation container; and
wherein an outlet temperature sensor is disposed downstream of the outlet valve to detect a temperature of coolant exhausted through the outlet of the insulation container, and an inlet temperature sensor is disposed upstream of the inlet valve to detect a temperature of coolant that flows therein through the inlet of the insulation container.

Abstract
A heat storage device of a vehicle may include an insulation container, a coolant passage connected to an engine, a heat exchanger having a fin formed on the coolant passage inside the insulation container, a phase change material charged in the insulation container to exchange heat with flowing coolant, a phase change material temperature sensor, a pressure sensor, an engine coolant temperature sensor, and a control portion that circulates the coolant according to the driving condition of the engine and the coolant temperature such that the coolant exchanges heat with the phase change material. Accordingly, fuel for warming an engine or heating an interior room is reduced, a separate heating device or a warm up device such as a PTC heater can be replaced, quality of the exhaust gas is quickly improved, and there is a merit in overcoming environmental regulations.
