Provided in the present invention is a thermal energy recovery device, which can increase energy inputted in an expander while cooling oil by means of an operating medium, and comprises: an evaporator (10); an oil separator (12); an expander (14); a driving force collector (16); an oil feeding flow path (18); a condenser (20); a pump (22); a circulation flow path (24); an oil cooler (32); an oil cooling flow path (40); an expansion valve (V1) arranged at a portion of the upper stream of the oil cooler (32) in the oil cooling flow path (40); and an expansion valve control unit (62) controlling an opened extent of the expansion valve (V1). Here, the oil cooler (32) allows oil flowing in the oil feeding flow path (18) and a mixing medium flowing in the oil cooling flow path (40) to exchange heat such that at least part of the mixing medium can be evaporated. Furthermore, an end portion of the down stream of the oil cooling flow path (40) is connected to the middle of the end portion of the expander (14). 작동 매체에 의해 기름을 냉각함과 함께, 팽창기에 투입되는 에너지를 증대시키는 것이 가능한 열 에너지 회수 장치를 제공한다. 증발기(10)와, 기름 분리기(12)와, 팽창기(14)와, 동력 회수기(16)와, 급유 유로(18)와, 응축기(20)와, 펌프(22)와, 순환 유로(24)와, 오일 쿨러(32)와, 기름 냉각 유로(40)와, 기름 냉각 유로(40) 중 오일 쿨러(32)의 상류측의 부위에 마련된 팽창 밸브(V1)와, 팽창 밸브(V1)의 개방도를 조정하는 팽창 밸브 조정부(62)를 구비하고, 오일 쿨러(32)는, 급유 유로(18)를 흐르는 기름과 기름 냉각 유로(40)를 흐르는 혼합 매체를 열 교환시킴으로써 혼합 매체의 적어도 일부를 증발시켜, 기름 냉각 유로(40)의 하류측의 단부는, 팽창기(14)의 중단부에 접속되어 있는 것.
