[0072] refer to Figure 1 to Figure 6 The first embodiment will be described. The facility temperature control device 1 of the first embodiment is installed in an electric vehicle (hereinafter, simply referred to as a "vehicle") such as an electric vehicle, a plug-in hybrid vehicle, or a hybrid vehicle. The equipment temperature control device 1 (hereinafter sometimes referred to as "this device 1") of the first embodiment cools or warms up a secondary battery (hereinafter referred to as "battery") mounted on a vehicle, and monitors the temperature of the battery. adjust.
[0073] First, the battery 2 which is the target device whose temperature is regulated by the device temperature adjustment device 1 will be described. A large battery 2 installed in a vehicle is mounted under a seat of the vehicle or under a trunk of the vehicle as a battery pack (that is, a power storage device), and the battery pack stores a plurality of battery modules in which a plurality of battery c...
Deformed example 1
[0123] refer to Figure 7 Modification 1 to the first embodiment will be described. Modification 1 changes the amount of working fluid sealed in the thermosyphon circuit of the equipment temperature adjustment device 1 compared to the first embodiment. Others are the same as the first embodiment, so only the parts that are different from the first embodiment are discussed. Be explained.
[0124] Figure 7 It shows the state that the facility temperature control device 1 is tilted at a predetermined angle. In Modification 1, the filling amount of the working fluid is adjusted so that the liquid level FL of the working fluid is at In the middle of the first gas phase passage 21 and the second gas phase passage 22 . In addition, the filling amount of the working fluid is adjusted so that the liquid level FL of the working fluid is at the level of the confluence part 30 when the facility temperature regulating unit 10 is in a horizontal state and when the facility temperature ...
Deformed example 2
[0127] refer to Figure 8 Modification 2 to the first embodiment will be described. Modification 2 also changes the amount of working fluid enclosed in the thermosiphon circuit of the facility temperature adjustment device 1 as compared to the first embodiment, and is otherwise the same as the first embodiment.
[0128] Figure 8 It shows the state that the facility temperature control device 1 is tilted at a predetermined angle. In Modification 2, the liquid level FL of the working fluid is located above the confluence portion 30 and in the middle of the confluence passage 40 . That is, the merging portion 30 is immersed in the liquid-phase working fluid. In this case, it is considered that when the battery 2 is cooled, the working fluid evaporated by exchanging heat with the battery 2 in the heat exchange part 113 of the equipment heat exchanger 11 is difficult to pass through the first gas-phase passage 21, the second The gas phase passage 22 and the confluence part 30 ...
