This application is based on Japanese Patent Application No. 2017-214857 filed on November 7, 2017 and Japanese Patent Application No. 2018-82432 filed on April 23, 2018, which are incorporated herein by reference. The contents of the description are incorporated by reference.

The present disclosure relates to a device temperature control apparatus that adjusts the temperature of a target device by phase change between a liquid phase and a gas phase of a working fluid.

In recent years, a technology using thermosiphon as a device temperature control device for adjusting the temperature of an electric device such as a power storage device mounted on an electric vehicle such as an electric vehicle or a hybrid vehicle has been studied.
In the device temperature control device described in Patent Document 1, when the battery is cooled, the working fluid inside the device heat exchanger absorbs heat from the battery, evaporates, and flows into the condenser through the gas phase passage. The liquid phase working fluid condensed by the condenser flows through the liquid phase passage into the equipment heat exchanger. As described above, the device temperature control device is configured to cool the battery by the phase change of the working fluid circulating in the thermosyphon circuit.

JP, 2015-041418, A

The inventors have found the following problems regarding the thermosiphon-type instrument temperature control apparatus as described in Patent Document 1. That is, the apparatus temperature control apparatus mounted in vehicles, such as a motor vehicle, becomes a structure which connected the several temperature control part by piping, in order to adjust temperature of object apparatuses, such as a secondary battery. In addition, when the device temperature control device is mounted on a vehicle such as a car, the device temperature control device may tilt along with the vehicle. For example, when the vehicle is moving up a hill, the front side in the traveling direction of the vehicle is positioned higher than the rear side in the vehicle traveling direction. And an apparatus temperature control apparatus will also be in the inclined state similarly to a vehicle.

In this case, the working fluid of the device temperature control apparatus is concentrated in the lower temperature control unit among the plurality of temperature control units under the influence of gravity. That is, a sufficient working fluid may not be supplied to the higher temperature control unit among the plurality of temperature control units.

On the other hand, when the device temperature control device is mounted on a vehicle such as a car, it is preferable to install an electric device such as a secondary battery and a temperature control unit on a flat surface. However, there may be a case where a flat space sufficient for installing the device temperature control device and the temperature control unit in the vehicle can not be secured.

Even in such a case, the working fluid of the device temperature control apparatus is concentrated in the lower temperature control section among the plurality of temperature control sections under the influence of gravity. That is, a sufficient working fluid may not be supplied to the higher temperature control unit among the plurality of temperature control units.

Hereinafter, embodiments of the present disclosure will be described based on the drawings. In the following embodiments, parts identical or equivalent to each other are denoted by the same reference numerals in the drawings in order to simplify the description.

First Embodiment
The device temperature control apparatus according to the present embodiment will be described with reference to FIGS. 1 to 7. The device temperature control device 10 shown in FIG. 1 is mounted on a vehicle such as an electric vehicle or a hybrid vehicle. Then, in the present embodiment, the device temperature control device 10 cools the

secondary batteries

12a and 12b mounted on the electric vehicle. That is, the objects to be cooled which the device temperature control apparatus 10 of the present embodiment is cooled are the

secondary batteries

12a and 12b.

In a vehicle equipped with the device temperature control device 10, electric power stored in a storage device including the

secondary batteries

12a and 12b as components is supplied to the electric motor via an inverter circuit or the like, whereby the vehicle travels. The

secondary batteries

12a, 12b generate heat when outputting power to the electric motor via the inverter.

Then, when the temperature of the

secondary batteries

12a and 12b becomes excessively high, the deterioration of the battery cells 13 constituting the

secondary batteries

12a and 12b is promoted, so that the output of the battery cells 13 and the self-heating are reduced. It is necessary to set restrictions on input.

Therefore, in order to secure the output and input of the battery cell 13, a cooling device for maintaining the

secondary batteries

12a and 12b at a predetermined temperature or lower is required.

In addition, the battery temperature rises not only while the vehicle is traveling but also when it is parked in summer. In addition, although the power storage device is often arranged under the floor of the vehicle or under the trunk room, the amount of heat per unit time given to the

secondary batteries

12a and 12b is small, but the battery temperature gradually rises by leaving for a long time .

If the

secondary batteries

12a and 12b are left in a high temperature state, the life of the

secondary batteries

12a and 12b is significantly reduced. Therefore, the battery temperature is maintained at a low temperature by cooling the

secondary batteries

12a and 12b even while the vehicle is left. Is desired.

The

secondary batteries

12a and 12b of the present embodiment are configured as a battery pack formed by stacking a plurality of battery cells 13 in the traveling direction of the vehicle, but if the temperature of each battery cell 13 varies, the battery cells 13 Deterioration is uneven and performance of the power storage device is degraded.

This is because the input / output characteristics of the power storage device are determined in accordance with the characteristics of the most deteriorated battery cell 13. Therefore, in order to cause the power storage device to exhibit desired performance over a long period of time, temperature equalization for reducing temperature variations among the plurality of battery cells 13 is important.

Also, as other cooling devices for cooling the

secondary batteries

12a and 12b, air blowing with a blower, air cooling using a refrigeration cycle, water cooling, or direct refrigerant cooling has been generally used. The blower has only a low cooling capacity because it only blows the air in the room.

Further, since the

secondary batteries

12a and 12b are cooled by the sensible heat of air in the blowing by the blower, the temperature difference between the upstream and the downstream of the air flow becomes large, and the temperature variation among the battery cells 13 can not be sufficiently suppressed. .

In the refrigeration cycle system, although the cooling capacity is high, since the heat exchange portion with the battery cell 13 is sensible heat cooling in either air cooling or water cooling, temperature variation among the battery cells 13 can not be sufficiently suppressed as well. Furthermore, it is not preferable to drive the compressor and the cooling fan of the refrigeration cycle while leaving the vehicle parked because it causes an increase in power consumption and noise.

From these backgrounds, in the device temperature control apparatus 10 according to the present embodiment, a thermosyphon system is employed in which the

secondary batteries

12a and 12b are cooled by natural convection of the refrigerant without using a compressor.

Specifically, as shown in FIG. 1, the device temperature control device 10 includes a cooler 14, a condenser 16, a forward pipe 21, and a return pipe 22. The condenser 16, the forward pipe 21, the cooler 14 and the return pipe 22 are annularly connected to form a thermosyphon circuit 26 in which a refrigerant as a working fluid of the device temperature control apparatus 10 circulates.

That is, the thermosiphon circuit 26 constitutes a thermosiphon that transfers heat by evaporation and condensation of the refrigerant. The thermosyphon circuit 26 is configured to be a loop-type thermosyphon in which a flow path through which the gas phase refrigerant flows and a flow path through which the liquid phase refrigerant flows are separated. The thermosiphon circuit 26 corresponds to a circulation circuit for circulating the working fluid.

In each of the drawings, the arrow DR1 indicates the vertical direction, and in the arrow DR1, the upper arrow indicates the upper side in the vertical direction of the vehicle, and the lower arrow indicates the lower side in the vertical direction of the vehicle. An arrow DR2 indicates the longitudinal direction of the vehicle. An arrow DR3 indicates the vehicle width direction.

A refrigerant is sealed and filled in the thermosyphon circuit 26 of the present embodiment. The thermosiphon circuit 26 is filled with the refrigerant. The refrigerant circulates through the thermosyphon circuit 26 by natural convection, and the device temperature adjusting device 10 adjusts the temperature of the

secondary batteries

12a and 12b by the phase change between the liquid phase and the gas phase of the refrigerant. In detail, the

secondary batteries

12a and 12b are cooled by the phase change of the refrigerant.

The refrigerant charged in the thermosyphon circuit 26 is, for example, a fluorocarbon-based refrigerant such as HFO-1234yf or HFC-134a. Alternatively, various working fluids other than fluorocarbon-based refrigerants such as water and ammonia may be used as the refrigerant.

As shown in FIG. 3, the cooler 14 is disposed between the

secondary batteries

12 a and 12 b. The cooler 14 exchanges heat between the heat of the

secondary batteries

12a and 12b and the heat of the refrigerant to cool the

secondary batteries

12a and 12b. The cooler 14 has a main body 143 made of, for example, a metal having high thermal conductivity.

As shown in FIG. 2, an inlet 141 and an outlet 142 are formed in the main body 143 of the cooler 14. The outlet 142 is disposed above the inlet 141 in the vertical direction.

The liquid passage 21 a formed inside the forward piping 21 is connected to the main body 143 of the cooler 14. Therefore, when the refrigerant circulates in the thermosyphon circuit 26, the liquid-phase refrigerant in the liquid passage 21 a flows into the internal space of the main body 143 via the inflow port 141.

The liquid passage 21 a is a flow path of a refrigerant that causes the liquid phase refrigerant to flow from the condenser 16 to the cooler 14. The outlet 142 of the cooler 14 is connected to the main body 143 of the cooler 14.

Therefore, when the refrigerant circulates in the thermosyphon circuit 26, the gas phase refrigerant in the cooler 14 exits the gas passage 22a through the outlet 142. The gas passage 22 a is a refrigerant flow passage that causes the gas phase refrigerant to flow from the outlet 142 of the cooler 14 to the condenser 16.

A liquid phase refrigerant with a relatively large specific gravity is accumulated below the main body 143 of the cooler 14, and a gas phase refrigerant with a relatively low specific gravity is accumulated above the main body 143 of the cooler 14. Therefore, the gas phase refrigerant in the main body 143 is exclusively discharged from the outlet 142 among the inlet 141 and the outlet 142.

The condenser 16 is a heat exchanger that exchanges heat between the gas phase refrigerant and the heat receiving fluid in the condenser 16 to dissipate the heat from the refrigerant to the heat receiving fluid. Specifically, the gas phase refrigerant flows from the return pipe 22 into the condenser inlet 161 of the condenser 16, and the condenser 16 condenses the refrigerant by radiating heat from the refrigerant to the heat receiving fluid. The liquid-phase refrigerant condensed by the condenser 16 flows out of the condenser outlet 162.

The heat receiving fluid which is heat-exchanged with the refrigerant in the condenser 16 is, for example, air outside the passenger compartment or water.

The condenser 16 of the present embodiment is installed so as to be positioned above the cooler 14 in the vertical direction even when the vehicle traveling direction of the vehicle or the vehicle width direction is inclined with respect to the horizontal direction. There is.

The condenser 16 is disposed above the cooler 14 in the vertical direction. In the present embodiment, the condenser 16 is housed in the front storage room or the trunk room. The front storage room is a room which is disposed on the front side in the vehicle traveling direction with respect to a vehicle compartment of the vehicle and stores a traveling engine and a traveling motor. The trunk room is a storage room which is disposed on the rear side in the vehicle traveling direction with respect to the vehicle compartment of the vehicle and stores luggage and the like.

A return pipe 22 is connected to the upper part of the condenser 16 in the vertical direction. Specifically, the return line pipe 22 is connected to the condenser 16 above the forward line pipe 21 in the vertical direction.

The device temperature control apparatus 10 according to the present embodiment has a configuration in which a large number of coolers 14 are connected by the forward pipe 21 and the return pipe 22 in order to adjust the temperature of the
