Problems solved by technology

In addition, the piping for connecting the evaporator and condenser of the thermosiphon circuit becomes longer, and the arrangement of the piping becomes complicated
In particular, in a thermosyphon circuit, since the liquid-phase working fluid flowing from the condenser to the evaporator flows by its own weight, it is difficult to arrange the piping in consideration of the vertical positional relationship.
[0011] In addition, when the number of batteries mounted on the vehicle is increased or decreased depending on the type of vehicle, the number of parts and design man-hours of the corresponding thermosiphon circuits may increase

no. 1 approach

[0071] The facility temperature control device of the present embodiment is mounted on electric vehicles (hereinafter, simply referred to as "vehicles") such as electric vehicles and hybrid vehicles. Such as Figure 1 ~ Figure 4 As shown, the device temperature adjustment device 1 functions as a cooling device that cools a secondary battery BP (hereinafter referred to as “battery BP”) mounted on a vehicle 2 . In addition, in the drawing, symbols BP1 , BP2 , and BP3 are assigned to batteries BP arranged in various parts of the vehicle 2 .

[0072] First, the battery BP which is the target device cooled by the device temperature adjustment device 1 will be described.

[0073] In the vehicle 2 equipped with the equipment temperature control device 1 , electric power stored in a power storage device (in other words, a battery pack) including the battery BP as a main component is supplied to the vehicle running motor via an inverter or the like. When the vehicle is running and th...

[0105] A second embodiment will be described. In the second embodiment, the configuration of the main condenser 40 is changed from that of the first embodiment, and since other parts are the same as those of the first embodiment, only the parts different from the first embodiment will be described.

[0106] Such as Figure 6 and Figure 7 As shown, the main condenser 40 of the second embodiment is equipped with the first to third heat exchange units 120 , 220 , and 320 respectively provided in the first to third thermosyphon circuits 10 , 20 , and 30 and the refrigeration cycle 60 . The evaporator 61 is formed integrally. The main condenser 40 is configured to exchange heat between the working fluid flowing through the first to third heat exchange units 120 , 220 , and 320 and the refrigerant circulating through the refrigeration cycle 60 . That is, in the second embodiment, the predetermined cooling and heating supply medium that exchanges heat with the working fluid flowi...

[0115] A third embodiment will be described. The third embodiment also changes the structure of the main condenser 40 with respect to the first and second embodiments, and since other parts are the same as those of the first and second embodiments, only the parts different from those of the first and second embodiments Be explained.

[0116] Such as Figure 8 As shown, the main condenser 40 of the third embodiment is composed of the first to third heat exchange parts 120, 220, 320 respectively provided in the first to third thermosiphon circuits 10, 20, 30 and the cooling water circuit 80. A part of the water channel 86 is integrally formed. The main condenser 40 is configured to exchange heat between the working fluid flowing through the first to third heat exchange units 120 , 220 , and 320 and the cooling water flowing through the water passage 86 of the cooling water circuit 80 . That is, in the third embodiment, the predetermined cooling fluid that exchanges heat with ...

Abstract

The present invention provides a device temperature regulator using a plurality of thermosiphon circuits capable of reducing the number of parts and improving vehicle mountability and vehicle mountability. The first thermosyphon circuit (10) has a first evaporator (11) and a first passage (12) through latent heat of evaporation of the working fluid evaporated by absorbing heat from the first object device (BP1) To cool the first object device (BP1), the first passage communicates with the first evaporator (11). The second thermosiphon circuit (20) includes a second evaporator (21) that evaporates the working fluid evaporated by absorbing heat from the second object device (BP2) and a second passage (22). The second object device (BP2) is cooled by latent heat, and the second passage (22) communicates with the second evaporator (21). The main condenser (40) has a first heat exchange part (120) provided in the first passage (12) and a second heat exchange part (220) provided in the second passage (22), and is configured to conduct the following fluids: Heat exchange: the working fluid flowing in the first heat exchanging part (120), the working fluid flowing in the second heat exchanging part (220), and a prescribed cooling and heating supply medium.
