Description

  The present invention relates to a device temperature control device that adjusts the temperature of a target device.

  2. Description of the Related Art Conventionally, a device temperature control device that adjusts the temperature of a target device by a loop thermosyphon method is known.

  The apparatus temperature control apparatus described in Patent Literature 1 includes an apparatus heat exchanger that exchanges heat between a battery as a target apparatus and a working fluid, a condenser that is disposed above the apparatus heat exchanger in the direction of gravity, and A gas-phase passage and a liquid-phase passage connecting the equipment heat exchanger and the condenser are provided.

JP2015-41418A

  The inventors have found the following problems with respect to a thermosiphon-type device temperature control device as described in Patent Document 1. That is, as shown in FIG. 42, when the device temperature control device 100 is mounted on a vehicle or the like, the device temperature control device 100 may be tilted together with the vehicle. In the state shown in FIG. 42, the equipment heat exchanger 110 included in the equipment temperature control apparatus 100 is configured such that the connecting portion 201 connected to the equipment heat exchanger 110 in the gas phase passage 200 is on the lower side in the gravity direction. Tilted. Therefore, the liquid level FL of the liquid-phase working fluid in the equipment heat exchanger 110 is positioned above the connection portion 201 of the gas-phase passage 200. That is, the connection part 201 of the gas phase passage 200 is submerged in the liquid-phase working fluid. In this case, the working fluid evaporated in the equipment heat exchanger 110 when the battery generates heat does not flow into the gas phase passage 200 and accumulates in the upper space 120 in the equipment heat exchanger 110. Therefore, the working fluid does not circulate through the thermosiphon circuit configured by the equipment heat exchanger 110, the gas phase passage 200, the condenser 500, and the liquid phase passage 550, and the equipment temperature control device 100 cannot cool the battery.

  The target device whose temperature is controlled by the device temperature control device 100 can be a battery pack mounted on an electric vehicle such as an electric vehicle or a hybrid vehicle. In that case, since the battery pack is composed of a large number of battery cells and is arranged under the floor of the electric vehicle, the physique in the horizontal direction is large. For this reason, the length of the heat exchanger for equipment 110 in the horizontal direction is increased along with the battery pack. Therefore, even when the inclination angle of the electric vehicle is small, there is a high possibility that the connection part 210 of the gas-phase passage 200 is immersed in the liquid-phase working fluid. That is, when the target device is a battery pack of an electric vehicle, the inclination of the electric vehicle greatly affects the battery cooling capacity of the device temperature control device 100.

  An object of this invention is to provide the apparatus temperature control apparatus which can adjust the temperature of an object apparatus even when an apparatus inclines in view of the said point.

  According to this, when the device temperature adjustment unit is inclined, one of the first connection unit and the second connection unit is positioned on the upper side in the gravity direction, and the other of the first connection unit and the second connection unit is on the lower side in the gravity direction. To position. Therefore, the working fluid evaporated in the equipment heat exchanger included in the equipment temperature adjustment section is at least from the first connection section or the second connection section located on the upper side in the direction of gravity to the first gas phase path or the second gas phase path. It flows through one side and enters the condenser. The working fluid condensed by the condenser flows through the liquid phase passage and flows into the equipment heat exchanger. Due to the circulation of the working fluid, the device temperature adjustment device can cool the target device even when the device temperature adjustment unit is inclined.

  Embodiments of the present invention will be described below with reference to the drawings. In the following embodiments, parts that are the same or equivalent to each other are given the same reference numerals, and descriptions thereof are omitted. In the description of each embodiment, terms such as first, second, and third are for convenience of description, and do not limit the number, arrangement, shape, and the like of each constituent member.

(First embodiment)
A first embodiment will be described with reference to FIGS. The apparatus temperature control device 1 of the first embodiment is mounted on an electric vehicle (hereinafter simply referred to as “vehicle”) such as an electric vehicle, a plug-in hybrid vehicle, or a hybrid vehicle. The apparatus temperature control device 1 (hereinafter sometimes referred to as “the device 1”) of the first embodiment cools or warms up a secondary battery (hereinafter referred to as “battery”) mounted on a vehicle, and the temperature of the battery. Is to adjust.

  First, the battery 2 as a target device for which the device temperature control device 1 performs temperature adjustment will be described. A large battery 2 installed in a vehicle is mounted as a battery pack (that is, a power storage device) in which a plurality of battery modules in which a plurality of battery cells 3 are combined is stored, for example, under a vehicle seat or under a trunk room. The electric power stored in the battery 2 is supplied to the vehicle driving motor via an inverter or the like. The battery 2 self-heats when power is supplied while the vehicle is running. When the battery 2 reaches a high temperature, not only cannot a sufficient function be exhibited, but also deterioration is promoted. Therefore, it is necessary to limit output and input so that self-heating is reduced. Therefore, in order to ensure the output and input of the battery 2, a cooling device for maintaining the battery 2 at a predetermined temperature or less is required.

  In addition, in the season when the outside air temperature is high such as summer, the temperature of the battery 2 rises not only when the vehicle is running but also when the vehicle is parked. Further, the battery 2 is often arranged under the floor of a vehicle or under a trunk room, and although the amount of heat given to the battery 2 per unit time is small, the temperature of the battery 2 gradually rises due to being left for a long time. If the battery 2 is left in a high temperature state, the life of the battery 2 is shortened. Therefore, it is desired to maintain the temperature of the battery 2 below a predetermined temperature even during parking of the vehicle.

  Furthermore, the battery 2 is composed of a plurality of battery cells 3. In the battery 2, if the temperature of each battery cell 3 varies, the battery cell 3 is unevenly deteriorated and the power storage performance is lowered. This is because the input / output characteristics of the battery 2 are determined according to the characteristics of the most deteriorated battery cell 3 because the battery 2 includes a series connection body of the plurality of battery cells 3. Therefore, in order for the battery 2 to exhibit desired performance over a long period of time, it is important to equalize the temperature so as to reduce the temperature variation among the plurality of battery cells 3.

  In general, as other cooling devices for cooling the battery 2, an air-cooling cooling means using a blower and a cooling means utilizing the cold heat of a vapor compression refrigeration cycle are generally used. However, since the air-cooled cooling means using the blower only blows air in the passenger compartment, the cooling capacity is low. Moreover, since the air blown by the blower cools the battery 2 with the sensible heat of the air, the temperature difference between the upstream and downstream of the air flow becomes large, and the temperature variation among the plurality of battery cells 3 cannot be sufficiently suppressed. Moreover, although the cooling means using the cold heat of the refrigeration cycle has a high cooling capacity, it is necessary to drive a compressor or the like that consumes a large amount of power while the vehicle is parked. This is undesirable because it leads to an increase in power consumption and an increase in noise.

  Therefore, the apparatus temperature control device 1 of the present embodiment employs a thermosiphon system that adjusts the temperature of the battery 2 by natural circulation of the working fluid without forcibly circulating the working fluid by a compressor.

  Next, the structure of the apparatus temperature control apparatus 1 is demonstrated. As shown in FIG. 1, the device temperature control apparatus 1 includes a device fluid adjusting unit 10, a plurality of gas phase passages 21, 22, 40, a condenser 50, a liquid phase passage 55, and the like that are connected to each other and sealed. It is configured as a circuit. The apparatus temperature control device 1 constitutes a loop-type thermosiphon circuit in which a flow path through which a gas-phase working fluid flows and a flow path through which a liquid-phase working fluid flows are separated. The thermosiphon circuit is filled with a predetermined amount of working fluid with its inside being evacuated. As the working fluid, for example, a fluorocarbon refrigerant such as HFO-1234yf or HFC-134a is used. The amount of the working fluid sealed is adjusted so that the liquid level FL of the working fluid is located in the middle of the height direction of the equipment heat exchanger. In the drawing, an example of the height of the liquid level FL of the working fluid is indicated by a one-dot chain line. In addition, the upper side and the lower side indicated by the double arrows in the drawing indicate the upper side and the lower side in the gravity direction in a state where the device temperature control device 1 is mounted on a vehicle or the like.

  As shown in FIGS. 1 to 3, the device temperature adjustment unit 10 of the first embodiment is configured by a single device heat exchanger 11. The equipment heat exchanger 11 has a shape having a longitudinal direction and a lateral direction as viewed from the direction of gravity. The equipment heat exchanger 11 includes a cylindrical upper header tank 111, a cylindrical lower header tank 112, and a heat exchange unit 113. The upper header tank 111 is provided at a position on the upper side in the gravitational direction of the equipment heat exchanger 11. The lower header tank 112 is provided at a position on the lower side in the gravity direction of the equipment heat exchanger 11. The plurality of heat exchange units 113 have a plurality of tubes that communicate the flow path in the upper header tank 111 and the flow path in the lower header tank 112. The heat exchanging unit 113 may have a plurality of flow paths formed inside a plate-like member. Each component of the equipment heat exchanger 11 is made of a metal having high thermal conductivity such as aluminum or copper. In addition, each structural member of the heat exchanger 11 for apparatuses can also be comprised with materials with high heat conductivity other than a metal.

  The battery 2 is installed outside the heat exchanging portion 113 via an electrically insulating heat conductive sheet 114. The heat conductive sheet 114 ensures insulation between the heat exchanging part 113 and the battery 2 and reduces the thermal resistance between the heat exchanging part 113 and the battery 2. In the present embodiment, in the battery 2, the surface 6 opposite to the surface 5 on which the terminals 4 are provided is installed in the heat exchanging unit 113 via the heat conductive sheet 114. It is also possible to directly connect the battery 2 and the heat exchanging unit 113 by omitting the heat conductive sheet 114.

  The plurality of battery cells 3 constituting the battery 2 are arranged in a direction crossing the gravitational direction. The installation method of the battery 2 is not limited to that shown in FIGS. 1 to 3, and any installation method can be adopted as will be described in the fifteenth and sixteenth embodiments described later. In addition, the number, shape, etc. of each battery cell 3 which comprises the battery 2 are not restricted to what was shown in FIGS. 1-3, Arbitrary things can be employ | adopted.

  The battery 2 can exchange heat with the working fluid inside the equipment heat exchanger 11. When the battery 2 generates heat, the liquid-phase working fluid in the equipment heat exchanger 11 evaporates. Thereby, the several battery cell 3 is cooled equally by the evaporation latent heat of a working fluid.

  Outflow ports 111a and 111b are provided on the left and right in the longitudinal direction of the upper header tank 111 of the equipment heat exchanger 11, respectively. The lower header tank 112 is provided with an inlet 112a. The outlets 111a and 111b are pipe connection parts for connecting the ends of the gas pipes constituting the gas phase passages 21, 22, and 40. The inflow port 112 a is a pipe connection part for connecting the ends of the liquid pipes constituting the liquid phase passage 55.

  The plurality of gas-phase passages 21, 22, and 40 are passages for flowing the gas-phase working fluid evaporated inside the equipment heat exchanger 11 to the condenser 50. In the present embodiment, the plurality of gas phase passages 21, 22, and 40 are configured to include the first gas phase passage 21, the second gas phase passage 22, and the merging passage 40. One end of the first gas phase passage 21 is connected to an outlet 111 a provided on one side in the longitudinal direction of the upper header tank 111 of the equipment heat exchanger 11. The end portion where the first gas phase passage 21 is connected to the equipment heat exchanger 11 is referred to as a first connection portion 211. One end of the second gas phase passage 22 is connected to an outlet 111 b provided on the other side in the longitudinal direction of the upper header tank 111 of the equipment heat exchanger 11. An end portion where the second gas phase passage 22 is connected to the equipment heat exchanger 11 is referred to as a second connection portion 221. The first connection portion 211 of the first gas phase passage 21 and the second connection portion 221 of the second gas phase passage 22 are provided at positions separated in the horizontal direction in one equipment heat exchanger 11. . Specifically, the first connection portion 211 of the first gas phase passage 21 and the second connection portion 221 of the second gas phase passage 22 are located on the outer side in the longitudinal direction from the heat exchange portion 113 in the equipment heat exchanger 11. Is provided.

  In addition, the 1st connection part 211 is provided in the vehicle forward side rather than the heat exchange part 113 among the heat exchangers 11 for apparatuses. Further, the second connection part 221 is provided on the vehicle rear side of the heat exchanger 11 for equipment with respect to the heat exchange part 113. That is, the 1st connection part 211 and the 2nd connection part 221 are provided in the place away in the vehicle front-back direction. The first gas phase passage 21 has a portion 21 a extending from the first connection portion 211 toward the front of the vehicle. The second gas phase passage 22 has a portion 22a extending from the second connecting portion 221 to the rear of the vehicle. The first gas phase passage 21 may extend upward from the first connection portion 211, or may extend upward and obliquely forward. The second gas phase passage 22 may extend upward from the second connection portion 221 or may extend upward and obliquely rearward.

  The following can be said as an effect of the first gas phase passage 21 having the portion 21a extending from the first connection portion 211 to the front of the vehicle. That is, as shown in FIG. 5, a portion 21 a extending from the first connection portion 211 to the front of the vehicle in the first gas phase passage 21 is a pipe for dealing with an inclination when the position of the condenser 50 is raised. Here, in the case where the first gas phase passage 21 is inclined as shown in FIG. 5 due to the portion 21a extending from the first connection portion 211 to the front of the vehicle, the heat exchange portion 113 of the equipment heat exchanger 11 However, the first gas phase passage 21 is not relatively lowered. Therefore, the gas-phase refrigerant evaporated in the heat exchanging unit 113 is easily guided to the first gas-phase passage 21 during the inclination.

  Further, the following can be said as an effect of the second gas phase passage 22 having the portion 22a extending from the second connection portion 221 to the rear of the vehicle. That is, as shown in FIG. 6, a portion 22 a extending from the second connection portion 221 toward the rear of the vehicle in the second gas-phase passage 22 is a pipe for dealing with an inclination when the position of the condenser 50 is lowered. Here, in the case where the second gas phase passage 22 is inclined as shown in FIG. 6 due to the portion 22a extending from the first connection portion 221 to the rear of the vehicle, the heat exchange portion 113 of the equipment heat exchanger 11 However, the second gas phase passage 22 is not relatively lowered. Therefore, the gas-phase refrigerant evaporated in the heat exchanging unit 113 is easily guided to the second gas-phase passage 22 during the inclination.

  An end of the first gas phase passage 21 opposite to the equipment heat exchanger 11 and an end of the second gas phase passage 22 opposite to the equipment heat exchanger 11 are joined together 30. Connected with. A junction passage 40 is connected between the junction 30 and the condenser 50. The merge portion 30 is provided above the first connection portion 211 and the second connection portion 221 in the gravity direction. The working fluid flowing through the first gas phase passage 21 and the working fluid flowing through the second gas phase passage 22 merge at the junction 30. The working fluid merged at the merge section 30 flows to the condenser 50 through the merge passage 40.

  The condenser 50 is disposed above the apparatus heat exchanger 11 in the gravity direction. The condenser 50 is a heat exchanger for exchanging heat between a gas phase working fluid that has flowed into the condenser 50 through the gas phase passages 21, 22, and 40 and a predetermined heat receiving medium. The predetermined heat receiving medium that exchanges heat with the working fluid flowing through the condenser 50 may employ various heat media such as a refrigerant circulating in the refrigeration cycle, cooling water circulating in the cooling water circuit, or air. Is possible. For example, when air is adopted as a predetermined heat receiving medium for exchanging heat with the working fluid flowing through the condenser 50, the condenser 50 includes air or traveling air blown by a fan (not shown) and a gas-phase working fluid. It is configured as an air-cooled heat exchanger that exchanges heat with each other. In that case, the gas phase working fluid flowing through the condenser 50 is condensed by releasing heat to the air passing through the condenser 50. Note that the condenser 50 is generally provided in an engine room in front of the vehicle.

  The condenser 50 is not limited to a position above the liquid level FL of the working fluid as illustrated in the drawings, and may be provided at a position straddling the liquid level FL of the working fluid in the height direction.

  The liquid phase passage 55 is a passage for allowing the liquid phase working fluid condensed inside the condenser 50 to flow to the equipment heat exchanger 11. The end of the liquid phase passage 55 opposite to the condenser 50 is connected to an inflow port 112 a provided in the lower header tank 112 of the equipment heat exchanger 11. As a result, the working fluid condensed into the liquid phase in the condenser 50 flows down through the liquid phase passage 55 by its own weight and flows into the equipment heat exchanger 11.

  The gas phase passages 21, 22, 40 and the liquid phase passage 55 are names for convenience, and do not mean a passage through which only a gas phase or liquid phase working fluid flows. That is, both the gas phase and the liquid phase working fluid may flow in any of the gas phase passages 21, 22, 40 and the liquid phase passage 55. In addition, the shape of the gas phase passages 21, 22, 40 and the liquid phase passage 55 can be appropriately changed in consideration of the mountability to the vehicle.

Next, the flow of the working fluid when the device temperature control device 1 cools the battery 2 will be described. <Horizontal state>
FIG. 4 shows a case where the device temperature adjustment unit 10 is in a horizontal state. In the present embodiment, the amount of working fluid enclosed is such that the liquid level FL of the working fluid is in the height direction of the heat exchanging unit 113 when the device temperature control device 1 is in the non-operating state and the device temperature adjusting unit 10 is in the horizontal state. It is located in the middle and is adjusted so that the first connection part 211 and the second connection part 221 are above the liquid level FL of the working fluid.

  When the apparatus temperature control device 1 is in an operating state and the battery 2 is cooled, the condenser 50 performs heat exchange between the gas-phase working fluid and a predetermined heat receiving medium. Specifically, when the vehicle is stopped, a fan (not shown) for blowing air to the condenser 50 is driven to blow air by the fan. When the vehicle is traveling, the driving wind does not need to be driven because the traveling wind flows to the condenser 50. Alternatively, a compressor of a refrigeration cycle (not shown) for exchanging heat with the working fluid flowing through the condenser 50 is driven, and the refrigerant circulates through the refrigeration cycle. Or the pump of the cooling water circuit which is not shown in figure for exchanging heat with the working fluid which flows through the condenser 50 is driven, and cooling water circulates through the cooling water circuit.

  As a result, the liquid-phase working fluid condensed by the condenser 50 flows through the liquid-phase passage 55 by its own weight, and flows into the lower header tank 112 of the equipment heat exchanger 11 from the inlet. The working fluid that has flowed into the lower header tank 112 is divided into a plurality of flow paths that the heat exchange unit 113 has. Here, in the present embodiment, the amount of the working fluid enclosed is adjusted so that the liquid level FL of the working fluid is positioned in the middle of the heat exchanging unit 113 when the device temperature adjusting unit 10 is in a horizontal state. Therefore, the first connection part 211 and the second connection part 221 are located above the liquid level FL of the working fluid in the device temperature adjustment part 10.

  The liquid-phase working fluid that flows through the plurality of flow paths of the heat exchange unit 113 evaporates by exchanging heat with the battery 2. In this process, the battery 2 is cooled by the latent heat of vaporization of the working fluid. Thereafter, the working fluid that has become a gas phase is merged in the upper header tank 111, and the first connection portion 211 and the second connection portion 221 that are connected to one and the other in the longitudinal direction of the upper header tank 111 respectively. It flows to the condenser 50 through the phase passage 21, the second gas phase passage 22 and the merge passage 40.

  As described above, the flow of the working fluid during cooling of the battery 2 is as follows: the condenser 50 → the liquid phase passage 55 → the lower header tank 112 → the heat exchange unit 113 → the upper header tank 111 → the first gas phase passage 21, the second gas The order of the phase passage 22 → the joining passage 40 → the condenser 50 is obtained. That is, a loop-shaped flow path including the equipment heat exchanger 11 and the condenser 50 is formed.

<Inclined state>
Next, the case where the apparatus temperature control apparatus 1 is in an inclined state will be described. 5 and 6 show a state in which the device temperature control device 1 is inclined at a predetermined angle. The working fluid is sealed in such a manner that the liquid level FL of the working fluid is above one of the first connecting portion 211 and the second connecting portion 221 when the device temperature adjusting portion 10 is inclined at a predetermined angle, and the first connecting portion 211 Or it is adjusted so that it may exist in the other lower side of the 2nd connection part 221. FIG. Further, the amount of the working fluid enclosed is adjusted so that the liquid level FL of the working fluid is below the junction 30 when the device temperature adjusting unit 10 is inclined at a predetermined angle.

  In addition, the predetermined angle used as the reference | standard for adjusting the enclosure amount of a working fluid is suitably set according to the use environment etc. of the vehicle in which the apparatus temperature control apparatus 1 is mounted. In the present embodiment, the predetermined angle is set as 25 °, for example. Note that the predetermined angle can be appropriately set, for example, between 5 ° and 25 °. By the way, as for the apparatus temperature control apparatus 1, it is desirable to set it as the structure corresponding to the inclination of the front-back direction of a vehicle rather than the left-right direction of a vehicle. A traveling vehicle tends to be maintained for a long time in the vehicle front-rear direction, such as during climbing, while the vehicle left-right direction inclination is not maintained for a long time. Therefore, the necessity for the device temperature control device 1 to correspond to the vehicle longitudinal direction is higher. In addition, the device temperature control device 1 is also effective in terms of inertial force acting on the vehicle. At this time, the state in which the inertial force acts in the vehicle longitudinal direction in a scene such as acceleration or deceleration is easily maintained for a long time. On the other hand, the state in which the inertial force is applied in the left-right direction of the vehicle due to the curve or the like is not maintained for a long time. There is a higher need for the device temperature control device 1 in the vehicle front-rear direction.

  FIG. 5 shows a state in which the condenser 50 side of the equipment heat exchanger 11 is inclined so as to be on the upper side. This state is a state in which, for example, when the condenser 50 is installed in front of the vehicle, the vehicle is inclined so that the front of the vehicle is upward. At this time, the first connection portion 211 of the first gas phase passage 21 connected to one of the longitudinal directions of the upper header tank 111 is above the liquid level FL of the working fluid, and is connected to the other longitudinal direction of the upper header tank 111. The second connection portion 221 of the second gas phase passage 22 is below the liquid level FL of the working fluid.

  When the device temperature control device 1 is in an operating state and the battery 2 is cooled, the liquid-phase working fluid condensed in the condenser 50 flows through the liquid-phase passage 55 as shown by the arrows in FIG. It flows into the lower header tank 112 of the vessel 11. The working fluid that has flowed into the lower header tank 112 is divided into a plurality of flow paths of the heat exchange unit 113 and is evaporated by heat exchange with the battery 2. In the case of FIG. 5, the vapor-phase working fluid evaporated in the heat exchange unit 113 passes through the first gas-phase passage 21 and the junction passage 40 from the first connection portion 211 above the liquid level FL of the working fluid, and is condensed. Flows to vessel 50.

  On the other hand, FIG. 6 shows a state in which the condenser 50 side of the equipment heat exchanger 11 is inclined downward. In this state, the first connecting portion 211 of the first gas phase passage 21 connected to one of the upper header tanks 111 in the longitudinal direction is below the liquid level FL of the working fluid, and the other of the upper header tanks 111 in the longitudinal direction of the upper header tank 111. The second connection part 221 of the second gas phase passage 22 to be connected is above the liquid level FL of the working fluid.

  When the device temperature control device 1 is in an operating state and the battery 2 is cooled, the liquid-phase working fluid condensed by the condenser 50 is cooled in the liquid-phase passage 55 when the battery 2 is cooled, as shown by the arrows in FIG. It flows into the lower header tank 112 of the equipment heat exchanger 11. The working fluid that has flowed into the lower header tank 112 is divided into a plurality of flow paths of the heat exchange unit 113 and is evaporated by heat exchange with the battery 2. In the case of FIG. 6, the vapor-phase working fluid evaporated in the heat exchanging portion 113 is condensed through the second connection portion 221 above the liquid level FL of the working fluid through the second vapor-phase passage 22 and the merge passage 40. Flows to vessel 50. Thus, in the first embodiment, the battery 2 can be cooled regardless of which side of the longitudinal direction the apparatus heat exchanger 11 is inclined.

Next, the liquid level FL of the working fluid will be described in detail.
When the apparatus 1 is operated, that is, when evaporation occurs in the apparatus temperature adjusting unit 10 and condensation occurs in the condenser 50, the liquid level changes somewhat up and down due to the pressure balance during evaporation. As described above, in the present embodiment, the amount of working fluid sealed is adjusted so that the first connecting portion 211 and the second connecting portion 221 are located above the liquid level of the working fluid. If the liquid level of the working fluid is not adjusted in this way, the gas-phase working fluid cannot be stably removed, so performance cannot be ensured, or only when the liquid level has moved down slightly. Since the working fluid cannot be removed, the performance cannot be secured stably.

  When the apparatus 1 is not operated, that is, when evaporation does not occur in the device temperature adjustment unit 10 and when condensation does not occur in the condenser 50, the liquid level is stationary. In this state, if the relationship that the first connection part 211 and the second connection part 221 are located above the liquid level of the working fluid is not satisfied, a cooling heat source is connected to the condenser 50 in order to operate the apparatus 1. Even if supplied, there is no path through which the vapor-phase working fluid evaporated in the device temperature adjusting unit 10 begins to escape. That is, the stable operation of the device 1 cannot be started.

  Here, the operation principle of the device 1 will be described. The working fluid evaporates in the apparatus temperature adjusting unit 10 to become a gas phase, and the gas phase working fluid is condensed in the condenser 50 to become a liquid phase working fluid, and the liquid phase working fluid becomes a liquid phase passage. Accumulate. At this time, the liquid level difference between the device temperature adjusting unit 10 and the liquid phase passage 55 operates as a drive source. In other words, a part of the liquid phase refrigerant in the device temperature adjusting unit 10 moves to the liquid phase passage 55 via the condenser 50 after evaporation, thereby causing a liquid level difference and circulating the working fluid.

  Next, the liquid level during operation and the liquid level during non-operation are compared. As described above, since a part of the liquid refrigerant of the device temperature adjusting unit 10 moves to the liquid phase passage 55 via the condenser 50 after evaporation, the apparatus 1 operates. The liquid level during operation and the liquid level during operation are higher than the liquid level during non-operation. Due to the pressure balance, the liquid level during operation slightly rises and falls, causing an event that the liquid level during operation temporarily becomes higher than the liquid level during non-operation, but in general the liquid level during non-operation The liquid level during operation can be considered higher than that during non-operation.

  From the above, regarding the relationship that the first connection portion 211 and the second connection portion 221 are located above the liquid level of the working fluid, if the relationship is satisfied at the liquid level when the device 1 is not in operation, Cooling performance can be ensured in almost all situations of the apparatus 1.

The apparatus temperature control apparatus 1 of 1st Embodiment demonstrated above has the following effect.
(1) In the first embodiment, the first connection part 211 in which the first gas phase passage 21 is connected to the equipment heat exchanger 11 and the second connection in which the second gas phase passage 22 is connected to the equipment heat exchanger 11.

Thereby, when the equipment heat exchanger 11 is inclined, one of the first connection part 211 and the second connection part 221 is positioned on the upper side in the gravity direction, and the other of the first connection part 211 and the second connection part 221 is gravity. Located in the lower direction. Therefore, the working fluid evaporated in the equipment heat exchanger 11 is at least one of the first gas phase passage 21 and the second gas phase passage 22 from the first connection portion 211 or the second connection portion 221 located on the upper side in the gravity direction. And flows into the condenser 50. The working fluid condensed by the condenser 50 flows through the liquid phase passage 55 and flows into the equipment heat exchanger 11. By such a circulation of the working fluid, the device temperature control device 1 can cool the battery 2 even when the device heat exchanger 11 is inclined to either side in the longitudinal direction.

  (2) In the first embodiment, the amount of working fluid enclosed is such that the liquid level FL of the working fluid is the heat for the device when the device temperature control device 1 is in a non-operating state and the device heat exchanger 11 is in a horizontal state.

In addition, the amount of the working fluid enclosed is such that when the device temperature control device 1 is in a non-operating state and the device heat exchanger 11 is in a horizontal state, the first connecting portion 211 and the second connecting portion 221 are liquids of the working fluid. It is adjusted to be positioned above the surface FL. Thereby, the gas release property of the 1st connection part 211 or the 2nd connection part 221 becomes good. That is, the pressure loss of the gaseous working fluid flowing from the equipment heat exchanger 11 to the first gas phase passage 21 or the second gas phase passage 22 via the first connection portion 211 or the second connection portion 221 is reduced. The Therefore, the apparatus temperature control apparatus 1 can improve the cooling performance of the battery 2 by improving the circulation of the working fluid in the thermosiphon circuit.

Thereby, when the equipment heat exchanger 11 is inclined, the working fluid evaporated inside the equipment heat exchanger 11 is not submerged in the liquid-phase working fluid. It flows from the connecting portion 221 to the first gas phase passage 21 or the second gas phase passage 22.

If the merging section 30 is submerged, the vapor-phase working fluid flowing through the first gas phase passage 21 or the second gas phase passage 22 passes through the merging section 30 when the equipment heat exchanger 11 is inclined. Can be difficult. On the other hand, if the merger 30 is not submerged when the equipment heat exchanger 11 is inclined, the gas-phase working fluid flowing in the first vapor phase passage 21 or the second vapor phase passage 22 30 easily passes to the condenser 50. Therefore, the apparatus temperature control apparatus 1 can improve the cooling performance of the battery 2 by improving the circulation of the working fluid in the thermosiphon circuit.

  (6) In 1st Embodiment, the 1st connection part 211 and the 2nd connection part 221 are provided in the position away in the horizontal direction among the heat exchangers 11 for apparatuses. Thereby, when the equipment heat exchanger 11 is tilted, the working fluid evaporated in the equipment heat exchanger 11 flows from the first connection portion 211 or the second connection portion 221 located on the upper side in the gravity direction to the first gas phase. It flows through the passage 21 or the second gas phase passage 22 and flows into the condenser 50. Therefore, the apparatus temperature control apparatus 1 can cool the battery 2 even when the apparatus heat exchanger 11 is inclined.

  (7) In 1st Embodiment, the 1st connection part 211 and the 2nd connection part 221 are provided in the longitudinal direction outer side from the heat exchange part 113 among the heat exchangers 11 for apparatuses.
