Chemical heat storage apparatus

A chemical heat storage apparatus provided in a mobile machine in which an internal combustion engine is mounted and heating a heating object that comprises engine oil, the chemical heat storage apparatus comprising:

• a reactor disposed capable of exchanging heat with the heating object and including a reaction material generating heat by a chemical reaction with a reaction medium when the reaction medium is supplied, the reaction medium being desorbed from the reaction material when heat is given;
• a reservoir storing the reaction medium;
• a reaction medium flow system allowing the reaction medium to flow between the reactor and the reservoir;
• a heat generation controller that is programmed to control the reaction medium flow system such that heat is generated by a chemical reaction between the reaction medium and the reaction material and the heating object is heated when the internal combustion engine is started;
• a temperature sensor that detects the temperature of the exhaust gas discharged from the internal combustion engine;
• a heat exchanger performing heat exchange between the exhaust gas and a heat medium;
• a heat medium circulation system circulating the heat medium between the heat exchanger and the reactor;
• a heat medium circulation controller that is programmed to control the heat medium circulation system such that the reaction medium is desorbed from the reaction material by heat of the heat medium and the heating object is heated when the temperature of the exhaust gas detected by the temperature sensor reaches the predetermined temperature or more, wherein
• the reactor includes a heating object passage portion through which the heating object passes.
