Heat pump device

Abstract

Heat pump device (1), comprising: a refrigerant circuit (29) comprising a compressor (23) and a heat exchanger (20) configured to exchange heat between outside air and a refrigerant, wherein the refrigerant circuit (29) is filled with a flammable refrigerant; a fan (21) configured to blow air onto the heat exchanger (20); a pair of fan support posts (18) that support the fan; a control board (40) configured to control the compressor (23) and the fan (21); an electrical component box (30, 230) accommodating the control board (40), wherein the electrical component box (30, 230) has a sealed structure; and a heat sink (34) which is installed in close contact with the control board (40), wherein the heat sink (34) is exposed outside the electrical component box (30, 230), characterized in that the electrical component box (30, 230) is supported by at least one of the fan support posts (18), the cooling element (34) is arranged in front of the heat exchanger (20), and at least part of the heat sink (34) is located between the pair of fan support posts (18).
