PROBLEM TO BE SOLVED: To improve heat exchange efficiency by changing an arrangement and shape of components, and to improve rigidity as an entire device by dispersing the concentration of impact at the time of earthquake from a piping connection section. SOLUTION: A heating element housing box cooling device 1 has a first coolant cycle 28 equipped with a first evaporator 14 and a first condenser 20, and a second coolant cycle 29 equipped with a second evaporator 17 and a second condenser 23. The connection positions of a first coolant liquid pipe 26, a second coolant liquid pipe 27, a first coolant steam pipe 24, and a second coolant steam pipe 25 are laterally reversed with respect to the ventilation direction, and heat exchange efficiency decrease points of them are complemented with each other to provide a heating body housing box cooling device of a high efficiency as a whole.
