Heat generating body box housing refrigeration device

A heat generating body box housing refrigeration device that refrigerates a heat generating body box housing accommodating a heat generating body, comprising:

• a first condenser and a second condenser that condense a refrigerant;
• a first evaporator and a second evaporator that vaporize the refrigerant;
• and
• an outdoor blower that sucks air outside of the heat generating body box housing and blows the air to promote heat transfers of the first condenser and the second condenser, wherein
• the first condenser and the first evaporator are connected with a first refrigerant liquid pipe and a first refrigerant steam pipe to constitute a first refrigerant cycle,
• the second condenser and the second evaporator are connected with a second refrigerant liquid pipe and a second refrigerant steam pipe to constitute a second refrigerant cycle,
• the first condenser of a rectangular shape includes a first condenser steam header on an upper side and a first condenser liquid header on a lower side,
• the first evaporator of a rectangular shape includes a first evaporator steam header on an upper side and a first evaporator liquid header on a lower side,
• the second condenser of a rectangular shape includes a second condenser steam header on an upper side and a second condenser liquid header on a lower side,
• the second evaporator of a rectangular shape includes a second evaporator steam header on an upper side and a second evaporator liquid header on a lower side,
• the first condenser, the second condenser, the first evaporator, and the second evaporator are vertically disposed with distances between one another,
• the first refrigerant liquid pipe is connected between a first joint in one end portion of the first condenser liquid header and a second joint in one end portion of the first evaporator liquid header,
• the first refrigerant steam pipe is connected between a third joint of the first condenser steam header and a fourth joint of the first evaporator steam header, the third joint located diagonally with respect to the first joint in the first condenser, and the fourth joint located diagonally with respect to the second joint in the first evaporator,
• the second refrigerant liquid pipe is connected between a fifth joint of the second condenser liquid header and a sixth joint of the second evaporator liquid header, the fifth joint located in a position facing another end portion different from that of the first joint, and the sixth joint located in a position facing another end portion different from that of the second joint, and
• the second refrigerant steam pipe is connected between a seventh joint of the second condenser steam header and an eighth joint of the second evaporator steam header, the seventh joint located in a position facing another end portion different from that of the third joint, and the eighth joint located in a position facing another end portion different from that of the fourth joint.
