In conventional technology, heat exchange between the battery and the refrigerant is realized directly or indirectly using various structures such as air cooling, water cooling, and direct refrigerant cooling, but all of these systems have complex structures; Not only does this increase the cost, but it also tends to cause deterioration in heat exchange efficiency and system efficiency, and the amount of refrigerant used increases, causing an increase in vehicle weight.

Note that the battery 1 of the embodiment corresponds to the temperature-controlled object of the present invention, and the wick 5 of the embodiment corresponds to the (first) inert medium moving member of the present invention.

According to the first feature of the present invention, the liquid inert medium, which has been moved in the storage box from the storage section to the heat exchangeable position by the inert medium moving member, is converted into gas by heat transfer from the temperature-controlled body. The gaseous inert medium is cooled by contacting the storage box, and the inert medium is changed to a liquid state and returned to the storage section. Cooling can be performed with a simple system that utilizes the latent heat of an inert medium, which can contribute to cost reduction. Moreover, since the amount of inert medium used is small, an increase in the weight of the temperature control device can also be avoided.

It also includes a temperature measurement unit that measures the temperature inside and outside the storage box, a heat exchanger that changes the temperature of the inert medium by being placed in a position that contacts the inside of the storage box or the outer wall of the storage box, and a heat exchanger that changes the temperature of the inert medium. a heat controller that controls the temperature of the exchanger, the heat controller controls the heat exchanger based on temperature measurement data inside and outside the storage box measured by the temperature measurement section, and By measuring not only the temperature inside the storage box, but also the temperature outside the storage box, the heat controller can efficiently control the amount of heat given to the heat exchanger with high precision, and use an inert medium. Therefore, it is possible to more appropriately control the temperature of the temperature-controlled object.

Further, according to the second feature of the present invention, the heat is used when the temperature of the temperature-controlled body when generating heat is lower than the outside temperature, or when the calorific value of the temperature-controlled body is greater than the natural heat dissipation amount. Since the exchanger is a cooling heat exchanger that cools the inert medium, even if the inert medium is vaporized by receiving the heat of the temperature controlled object whose temperature is lower than the external temperature, the gaseous inert The medium can be cooled in a cooling heat exchanger to transform the inert medium into a liquid state. Furthermore, if the amount of heat generated by the temperature-controlled object is greater than the natural heat dissipation amount, the temperature of the temperature-controlled object will rise, but even in such a case, the internal temperature of the storage box can be lowered to reduce the temperature-controlled object's temperature. Temperature can be lowered.

According to the third feature of the present invention, the heat exchanger used when the allowable lower limit temperature of the temperature-controlled body is equal to or higher than the external temperature is a heating heat exchanger for heating an inert medium. Since the inert medium is a container, even if the inert medium solidifies, the solid inert medium can be heated with a heating heat exchanger to change the inert medium to a liquid state.

According to the fourth feature of the present invention, the cooling heat exchanger is disposed at a position not in contact with the inert medium storage section, and the temperature of the temperature-controlled object measured by the temperature measuring section is equal to or less than the first temperature. The cooling heat exchanger cools the inert medium when the temperature is higher than the set value (for example, the upper limit temperature that can be used by battery 1), so when the liquid inert medium changes to gas, the inert medium is Can be effectively cooled.

According to the fifth feature of the present invention, the heating heat exchanger is disposed in a position where it is in direct contact with the inert medium storage section or indirectly through the storage box, so that the inert medium can be effectively removed. It can be heated to. In addition, since the heating heat exchanger heats the inert medium when the temperature of the temperature-controlled object is lower than the second set value (for example, the lowest usable temperature of the temperature-controlled object), the liquid inert medium When transformed into a solid, the inert medium can be effectively heated.

According to the ninth feature of the present invention, a plurality of temperature-controlled bodies and a plurality of inert medium moving members are provided, and the two are arranged alternately such that the inert medium moving member is sandwiched between the temperature-controlled bodies. Therefore, the temperature-controlled body and the inert medium moving member can be compactly arranged in the housing box while ensuring a wide contact area between the two.

Sometimes the inert medium is moved from the input part to the injection part by a pump via the second inert medium movement member, and is injected from the injection part towards the temperature controlled object, so usually the first inert medium movement member is used to cool the temperature controlled object, but when the temperature of the temperature controlled object suddenly rises and the first inert medium moving member alone cannot cool the temperature controlled object, the temperature controlled object is cooled. When the temperature of the body exceeds the emergency temperature setting value, the temperature controlled object is rapidly cooled by the second inert medium moving member, so that a situation where the temperature of the temperature controlled object increases abnormally can be avoided. I can do it.

Note that "temperature measurement value" here is not limited to the absolute value of the measured temperature, but may also be the amount of change in two or more measured temperatures (for example, the differential value or integral value of the measured temperature). good.

Embodiments of the present invention will be described below based on the accompanying drawings.

FIG. 1 shows a temperature control device for a temperature-controlled object according to a first embodiment of the present invention. The temperature control device of the first embodiment is for controlling the temperature of a battery 1 as a temperature-controlled object, and a plurality of rectangular parallelepiped batteries 1 are housed side by side in a sealed storage box 2. At the same time, a storage section 4 for a liquid inert medium 3 is formed in the lower part of the interior of the storage box 2 . A plurality of wicks 5 are arranged between the plurality of batteries 1 so as to be in contact with the sides of the batteries 1, one wick 5 being sandwiched between each battery 1, and the two wicks 5 being arranged alternately. The wicks 5 extend with their lower ends to the reservoir 4 and are immersed in a liquid inert medium 3. The plurality of batteries 1 are housed above the storage section 4, and in this embodiment, the lower end of each battery 1 is immersed in the storage section 4 together with the wick 5.

Note that the battery 1 does not necessarily have to be immersed in the storage section 4. More specifically, a reservoir 4 is formed below the battery 1 , and a wick 5 extends to the reservoir 4 , and the wick 5 may move the inert medium 3 to the battery 1 .

The inert medium 3 may be any inert medium as long as it is in a liquid state at room temperature and changes into a gaseous state by heat transfer from the battery 1 upon contact with the battery 1. The temperature of the battery 1 is lowered by heat. Incidentally, in this embodiment, an inert medium 3 is used whose evaporation temperature is higher than the maximum external temperature and whose coagulation temperature is lower than the minimum external temperature. In the temperature range, the inert medium 3 can be used in liquid form.

The wick 5 also causes the inert medium 3 in the storage section 4 to rise by capillary action to a heat exchangeable position 6 where it contacts the side surface of the battery 1 and can exchange heat with the battery 1. The wick 5 constitutes an inert medium moving member of the present invention that moves the inert medium 3 from the storage section 4 to a heat exchangeable position 6 adjacent to the battery 1 where heat exchange with the battery 1 is possible. be. In this embodiment, a wick that utilizes capillary action is used to eliminate the need for a power source for the inert medium moving member, but the inert medium moving member is not limited to the wick. The inert medium 3 that has moved to the heat exchangeable position 6 in this way changes into a gaseous state due to heat transfer from the battery 1, contacts the storage box 2, is cooled in the storage box 2, and becomes a liquid state. After being transformed, it is returned to storage by gravity.

A cooling heat exchanger 7 is arranged above the storage box 2 so as to be in contact with the top wall of the storage box 2, and below the storage box 2 so as to be in contact with the bottom wall of the storage box 2. A heating heat exchanger 8 is arranged, and these heat exchangers 7 and 8 are connected to a heat controller 9 that controls them. Also, inside the storage box 2, there is an internal temperature measurement section 10 that measures the temperature T inside the storage box 2 (that is, the temperature of the battery 1), and a pressure measurement section 11 that measures the pressure P inside the storage box 2. An external temperature measuring section 12 is formed outside the storage box 2 to measure the temperature outside the storage box 2 (more specifically, the temperature To of the outer wall of the storage box 2). Furthermore, on the side wall of the storage box 2, a first airtight terminal 14 for extracting the electric power of the plurality of batteries 1 inside the storage box 2 to the external device 13, and a first airtight terminal 14 for taking out the electric power of the plurality of batteries 1 inside the storage box 2 to the external device 13, and a second airtight terminal 15 for transmitting the internal temperature T of the storage box 2 to the thermal controller 9; The heat controller 9 controls the heat exchangers 7 and 8 based on the temperature measurement data inside and outside the storage box 2 measured by the inside and outside temperature measurement units 11 and 12. control and change the temperature of the inert medium 3.

In this embodiment, the temperature of the battery 1 is measured as the temperature inside the storage box 2, but in addition to the temperature of the battery 21, the temperature of the inert medium 3 may also be measured. Furthermore, the first and second airtight terminals 14 and 15 are not limited to those described above, and may be configured to transmit other control signals.

In this embodiment, the external temperature measurement section 12 is arranged on the outer wall of the storage box 2 in order to measure the influence of the external temperature of the storage box 2 on the internal temperature of the storage box 2 with higher precision. The temperature of the outside air may be measured without being placed on the outer wall of the housing box 2, or the temperature of the outside wall of the storage box 2 and the outside air may be measured by installing at multiple locations on the outside wall and other locations.

In this embodiment, the cooling heat exchanger 7 and the heating heat exchanger 8 are arranged above and below the storage box 2 so as to be in contact with the upper and lower walls of the storage box 2. The heat exchangers 7 and 8 may be located at other positions as long as they are in contact with the outer wall of the storage box 2, and it is also possible to arrange these heat exchangers 7 and 8 inside the storage box 2. Note that when the heat exchangers 7 and 8 are arranged inside the storage box 2, the cooling heat exchanger 7 is placed in the storage section 4 for the inert medium 3 in order to effectively liquefy the vaporized inert medium 3. In addition, in order to effectively heat the inert medium 3, the heating heat exchanger 8 is placed in a position in direct contact with the storage portion 4 of the inert medium 3.

The cooling heat exchanger 7 is used to cool the inert medium 3 when the temperature of the battery 1 when it generates heat is lower than the external temperature To, or when the amount of heat generated by the battery 1 is greater than the natural heat radiation amount. The inert medium 3 is cooled when the temperature of the battery 1 measured by the internal temperature measuring section 10 is higher than a first set value (for example, the boiling point of the inert medium). Moreover, the cooling heat exchanger 7 may cool the inert medium 3 when the boiling point of the inert medium 3 is lower than the external temperature To.

The heating heat exchanger 8 is used to heat the inert medium 3 when the allowable lower limit temperature of the battery 1 is equal to or higher than the external temperature To (in other words, equal to or higher than the external temperature To). It is placed in indirect contact with the storage section 4 of the inert medium 3 via the storage box 2 (a position facing the storage section 4) with the storage box 2 in between, and the battery 1 The heating heat exchanger 8 heats the inert medium 3 when the temperature of the inert medium 3 is lower than the second set value.

Note that, if either of the cooling heat exchanger 7 and the heating heat exchanger 8 is unnecessary, it is also possible to omit it. Further, the pressure measuring unit 11 is arranged inside the housing box 2 in order to prevent the housing box from bursting due to an increase in the pressure inside the housing box 2, but this pressure measuring unit 11 can also be omitted if unnecessary. .

Next, the effects of this first embodiment will be explained.

In the first embodiment of the present invention, the temperature of the liquid inert medium 3 moved from the storage section 4 to the heat exchangeable position 6 by the wick 5 in the storage box 2 is increased by heat transfer from the battery 1. The gaseous inert medium 3 is cooled by contacting the storage box 2, and the inert medium 3 is changed into a liquid state and returned to the storage section 4 by gravity. Therefore, the battery 1 can be cooled by a simple system using the latent heat of the inert medium 3, which can contribute to cost reduction. Moreover, since the amount of inert medium 3 used is small, an increase in the weight of the temperature control device can also be avoided. Note that the inert medium 3 also undergoes heat exchange that increases the temperature of the medium without changing the state of the medium (substance) due to heat transfer from the battery 1, so heat exchange using sensible heat also occurs.

Further, an internal temperature measuring section 10 for measuring the temperature inside the storage box 2, an external temperature measuring section 12 for measuring the outside temperature, and an external temperature measuring section 12 for measuring the temperature inside the storage box 2, which are disposed at a position in contact with the outer wall of the storage box 2 and are arranged to measure the temperature inside the inert medium 3, are provided. It includes heat exchangers 7 and 8 that change the temperature, and a heat controller 9 that controls the temperature of the heat exchangers 7 and 8, and the heat controller 9 includes an internal temperature measuring section 10 and an external temperature measuring section 12. Since the heat exchangers 7 and 8 are controlled based on the temperature data measured inside and outside the storage box 2 and the temperature of the inert medium 3 is changed, not only the temperature inside the storage box 2 but also the temperature inside the storage box 2 is changed. By also measuring the temperature outside the storage box 2, the heat controller 9 can efficiently control the amount of heat given to the heat exchangers 7 and 8 with high precision, allowing for more appropriate temperature control of the battery 1 using the inert medium 3. It can be carried out.

Also, a cooling heat exchanger that cools the inert medium 3 as a heat exchanger when the temperature of the battery 1 when it generates heat is lower than the external temperature To, or when the amount of heat generated by the battery 1 is greater than the natural heat radiation amount. 7 is used, so even if the inert medium 3 is vaporized by receiving the heat of the battery 1 whose temperature is lower than the external temperature To, the gaseous inert medium 3 is cooled by the cooling heat exchanger 7, The inert medium 3 can be transformed into a liquid state. Furthermore, when the amount of heat generated by the battery 1 is greater than the amount of natural heat dissipation, the temperature of the battery 1 will rise, but even in such a case, it is possible to lower the temperature of the battery 1 by lowering the internal temperature of the storage box 2. can.

Furthermore, since the heating heat exchanger 8 that heats the inert medium 3 is used as a heat exchanger when the allowable lower limit temperature of the battery 1 is higher than the external temperature To, there is a case where the inert medium 3 solidifies. However, by heating the solid inert medium 3 with the heating heat exchanger 8, it is possible to change the inert medium 3 into a liquid state.

In addition, the cooling heat exchanger 7 is arranged at a position where it contacts the upper wall of the storage box 2 and does not come into contact with the storage section 4 of the inert medium 3, so that the temperature of the battery 1 measured by the internal temperature measuring section 10 is Since the cooling heat exchanger 7 cools the inert medium 3 only when the temperature is higher than the set value Tb of 1 (for example, the boiling point of the inert medium 3), when the liquid inert medium 3 changes to a gas, The inert medium 3 can be effectively cooled.

In addition, the heating heat exchanger 8 is disposed at a position where it comes into contact with the lower wall of the storage box 2, which indirectly contacts the storage section 4 of the inert medium 3 via the storage box 2. can be heated effectively. Moreover, since the heating heat exchanger 8 heats the inert medium when the temperature of the battery 1 is lower than the second set value Tf (for example, the lowest usable temperature of the battery 1), the liquid inert medium becomes solid. When changed, the inert medium 3 can be effectively heated.

It also includes two types of heat exchangers: a cooling heat exchanger 7 that cools the inert medium 3 and a heating heat exchanger 8 that heats the inert medium 3. The temperature T of the battery 1, which is disposed in a non-contact position with the storage section 4 of the inert medium 3 and measured by the internal temperature measuring section 10, is lower than the first set value Tb such as the upper limit temperature at which the battery 1 can be used. A second heat exchanger 8 is placed in direct contact with the storage 4 of the inert medium 3 or indirectly via the storage box 2 and cools the inert medium 3 when the battery 1 is heated. Since the inert medium 3 is heated when the temperature T is lower than the second set value Tf, such as the lower limit temperature at which the battery 1 can be used, the temperature T of the battery 1 can be kept within a usable range.

For example, when measuring the temperature of the inert medium 3 in addition to the temperature of the battery 1, the boiling point of the inert medium 3 is set as the first set value Tb, and the freezing point of the inert medium 3 is set as the first set value Tb. By using this as the set value Tf of 2, when the liquid inert medium 3 changes to a gas, the inert medium 3 is effectively cooled, and when the liquid inert medium 3 changes to a solid, the inert medium 3 is effectively cooled. It is also possible to effectively heat the active medium 3, and as a result, it is possible to prevent the temperature T of the battery 1 from rising or falling excessively.

Further, since the inert medium 3 whose evaporation temperature is higher than the maximum external temperature and whose solidification temperature is lower than the minimum external temperature is used, the inert medium 3 can be used in a liquid state over a wide temperature range.

Moreover, since the inert medium moving member is a wick 5 that moves the inert medium 3 from the storage section 4 to the heat exchangeable position 6 by capillary action, the power source of the inert medium moving member that moves the inert medium 3 can be made unnecessary.

Further, since a plurality of batteries 1 and a plurality of wicks 5 are provided, and the wicks 5 are arranged alternately so that the wicks 5 are sandwiched between the batteries 1, the batteries 1 and the wicks 5 can be placed in the storage box 2. It can be arranged compactly while ensuring a wide contact area.

Next, a second embodiment of the present invention will be described with reference to FIG. 2.

The temperature control device for temperature controlled objects according to the second embodiment shown in FIG. A liquid inert medium 3 is stored in a storage section 4 formed in the lower part of the battery 2 , and a wick 5 is disposed between each battery 1 . Further, above and below the storage box 2, a cooling heat exchanger 7 and a heating heat exchanger 8 are arranged as shown in FIG. Connected to 9. An internal temperature measurement section 10 and a pressure measurement section 11 are formed inside the storage box 2, and an external temperature measurement section 12 is formed outside the storage box 2. Furthermore, first to third airtight terminals 14 to 16 are formed on the side wall of the storage box 2, and these structures are the same as in the first embodiment.

In the second embodiment, the inert medium moving member disposed between the storage section 4 and the heat exchangeable position 6 in the storage box 2 is a first inert medium moving member 5 composed of a wick. This embodiment differs from the first embodiment in that it additionally includes a second inert medium moving member 20 having a pump 19.

The second inert medium moving member 20 has an input section 17 at one end connected to the storage section 4 for the inert medium 3, and an input section 17 for injecting the inert medium 3 from the top of the battery 1 toward the battery 1. It has an injection part 18 on the end side and the above-mentioned pump 19 which is arranged between the input part and the injection part and moves the inert medium 3 in the storage part 4 to the injection part 18, and has an internal temperature measuring part. When the temperature T of the battery 1 measured at 10 is lower than the emergency temperature setting value set as the emergency temperature, the inert medium 3 moves only inside the wick 5, which is the first inert medium moving member. However, when the temperature T of the battery 1 measured by the internal temperature measuring section 10 is equal to or higher than the emergency temperature setting value, the inert medium 3 is injected from the input section 17 by the pump 19 of the second inert medium moving member 20. 18, and is injected from the injection section 18 toward the top of the battery 1.

In the present embodiment, the temperature at which the inert medium 3 moves inside the second inert medium moving member 20 is "when the temperature T of the battery 1 is equal to or higher than the emergency temperature setting value." Temperatures other than the emergency temperature set value may be set. Moreover, the injection part 18 does not necessarily need to be located on the top side of the battery 1, and may be located on the side side of the battery 1.

According to the second embodiment, the battery 1 is normally cooled by the first inert medium moving member 5 using a wick, but due to a sudden temperature rise of the battery 1, etc., it becomes difficult to cool the battery 1 with only the wick. If the temperature of the battery 1 rises above the emergency temperature setting value when the battery 1 cannot be completely cooled, the second inert medium moving member 20 will rapidly cool the battery 1, thereby preventing the temperature of the battery 1 from rising abnormally. The situation can be avoided.

Next, a first embodiment of the present invention will be described with reference to FIG. 3.

A temperature control device for a temperature-controlled object according to a first embodiment of the present invention shown in FIG. A storage section 4 for a liquid inert medium 3 is formed in the lower part of the interior of the storage box 2 . A wick 5 as an inert medium moving member is arranged between each battery 1, and a cooling heat exchanger is provided above the storage box 2 to cool the inert medium 3 in contact with the upper wall of the storage box 2. A container 7 is placed. Further, a pressure measurement section 11 is formed inside the storage box 2, and an external temperature measurement section 12 is formed outside the storage box 2. These configurations are the same as those in the first and second embodiments, but the internal temperature measuring section 10 is not formed inside the storage box 2. Further, the heating heat exchanger for heating the inert medium 3 is not particularly essential, and the heating heat exchanger 8 is omitted in this reference embodiment.

Further, the storage box 2 is made to have a strength capable of withstanding a predetermined pressure Po, and when the pressure P inside the storage box 2 measured by the pressure measurement unit 11 is higher than the predetermined pressure Po, The changed inert medium 3 is cooled by the cooling heat exchanger 7 and changed into a liquid state, so that the pressure P inside the storage box 2 is lowered than the predetermined pressure Po. In addition, in this reference embodiment, the cooling heat exchanger 7 is arranged at a position above the storage box 2 in contact with the upper wall of the storage box 2; The cooling heat exchanger 7 may be placed in another position if necessary, and it is also possible to arrange the cooling heat exchanger 7 inside the storage box 2.

Further, the external temperature measurement section 12 that measures the temperature outside the storage box 2 is used to calculate the amount of evaporation of the inert medium 3 from the measured external temperature To, and is used for the pressure measurement section 11 and the cooling The cooling heat exchanger 7 is connected to a heat controller 9 together with the cooling heat exchanger 7 so that the calculated amount of evaporation of the inert medium 3 is smaller than the amount of condensation of the inert medium by the cooling heat exchanger 7. Heat exchanger 7 is controlled.

Further, the heat controller 9 connected to both the pressure measuring section 11 and the cooling heat exchanger 7 can control the pressure P inside the storage box 2 measured by the pressure measuring section 11 and the cooling heat exchanger 7, for example. The cooling heat exchanger 7 has a table showing the relationship between the operating power W of the storage box 2 and the operating power W of the cooling heat exchanger 7. It is provided by a thermal controller 9 connected to a mains power supply 22.

Regarding the control parameters (pressure P, operating power W, etc.) in the table, the heat amount of the inert medium 3 by the cooling heat exchanger 7 is determined after the pressure P inside the storage box 2 is measured by the pressure measurement unit 11. Any other parameter may be used as long as it is a controllable parameter in the process up to heat absorption. For example, it is not limited to the operating power W of the cooling heat exchanger 7, but may be the amount of heat absorbed per unit time of the cooling heat exchanger 7. Further, the control parameter is not limited to the measured value itself (for example, pressure P), but may be a measured value (amount of change in pressure P) calculated from two or more measured values.

The storage box 2 is equipped with a pressure release valve 21 (for example, a solenoid valve) that releases the gas inside the storage box 2 to the outside. The storage box 2 The gaseous inert medium 3 inside is discharged to the outside, and the pressure P inside the storage box 2 is lowered below the predetermined pressure Po.

In this reference embodiment, the inert medium 3 is basically condensed by the cooling heat exchanger 7, but for example, the amount of evaporation of the inert medium 3 is greater than the amount of condensation by the cooling heat exchanger 7. In many cases, in other words, for emergency purposes, the pressure release valve 21 is operated to release the inert medium 3 to the outside.

In addition, as a method of controlling the pressure release valve 21, the amount of inert medium 3 released to the outside of the storage box 2 is calculated based on the relationship between the pressure information inside the storage box 2 and the release time, and the amount of the inert medium 3 released to the outside of the storage box 2 is calculated. For example, if the total amount of released inert medium 3 exceeds a predetermined set value stored in the memory, a warning is issued, for example. It may also be made to emit a sound. Note that the purpose of the warning sound is to make people aware that the total amount of the inert medium 3 released exceeds a predetermined set value stored in memory, so any means that appeals to the five senses of the person may be used. Alternatively, other means may be used.

The battery 1 housed in the storage box 2 is a portable battery, and the cooling heat exchanger 7 is connected to both the external main power source 22 and the battery 1. Then, when the external main power supply 22 is in an uncontrollable state and the battery 1 is in a controllable state, the power supply source to the cooling heat exchanger 7 is switched from the external main power supply 22 to the battery 1, and the battery 1 is switched from the external main power supply 22 to the battery 1. The cooling heat exchanger 7 is driven by the power supplied from the inert medium 3, and the cooling heat exchanger 7 lowers the temperature of the inert medium 3.

Note that if the pressure release valve 21 is configured as a safety valve that opens at the predetermined pressure Po instead of being a control valve controlled by the heat controller 9, both the external main power source 22 and the battery 1 can be in an uncontrollable state. When the pressure P inside the storage box 2 is higher than the predetermined pressure Po, the pressure release valve 21 releases the gaseous inert medium 3 inside the storage box 2 to the outside, and the pressure inside the storage box 2 is reduced. P can be reduced to a safe pressure.

In addition, the storage box 2 has a filling port 23 for filling the inside of the storage box 2 with the inert medium 3, and the amount of liquid inert medium 3 stored inside the storage box 2 can be visually checked. It is provided with a transparent window-like visual recognition part 24 for indicating the storage capacity, and this visual recognition part 24 is provided with a scale so that the storage capacity can be seen. Note that this scale may be a mark that simply indicates a certain amount serving as a guide for the capacity, or may be a digital display of the capacity without using a transparent window. However, the amount of inert medium 3 in the storage box 2 that evaporates changes depending on the internal temperature of the storage box 2, so when displaying the storage amount digitally, it is optimized according to the internal temperature of the storage box 2. It is desirable to display the amount of liquid.

Next, the effects of the first embodiment of the present invention will be explained.

In the first embodiment of the present invention, similarly to the first embodiment, the liquid inert medium 3 that has been moved inside the storage box 2 from the storage section 4 to the heat exchangeable position 6 by the wick 5 is transferred to the battery. Since the battery 1 is cooled by changing it into a gaseous state by heat transfer from the inert medium 3, the battery 1 can be cooled by a simple system using the latent heat of the inert medium 3, which can contribute to cost reduction. Moreover, since the amount of inert medium 3 used is small, an increase in the weight of the temperature control device can also be avoided.

Further, it includes a pressure measuring unit 11 that measures the pressure P inside the storage box 2, and a cooling heat exchanger 7 that is disposed at a position in contact with the upper wall of the storage box 2 and cools the inert medium 3, When the pressure P inside the storage box 2 measured by the pressure measurement unit 11 is higher than the predetermined pressure Po that the storage box can withstand, the gaseous inert medium 3 is cooled by the cooling heat exchanger 7 and becomes a liquid. Since the pressure P inside the storage box 2 is lowered below the predetermined pressure Po, the inert medium 3 and the battery 1 inside the storage box 2 are controlled appropriately. The heat exchange with the battery 1 can be efficiently controlled, and the temperature of the battery 1 can be more appropriately controlled using the inert medium 3.

Although the object to be cooled by the cooling heat exchanger 7 is mainly the gaseous inert medium 3, the liquid inert medium 3 is also cooled through the wall surface of the storage box 2.

Moreover, in this reference embodiment, the internal state of the storage box 2 is entirely controlled by the pressure P, and there is no need to arrange a temperature measuring section inside the storage box 2, so it is possible to reduce the cost of the temperature control device for the battery 1. It becomes possible. Moreover, in general, temperature sensors receive heat from the object to be measured and require a certain amount of time for the temperature sensing part to reach the same temperature as the object, making it difficult to respond to sudden temperature changes of the object to be measured. In the reference embodiment, since the state inside the storage box 2 is controlled by pressure, it is possible to sufficiently cope with sudden temperature changes inside the storage box 2.

Note that the "state inside the storage box 2 controlled by the pressure P" in this reference embodiment refers to the state of the inert medium 3 that is directly controlled inside the storage box 2, and is not the state of the battery 1.

It also includes an external temperature measuring section 12 that measures the external temperature To of the storage box 2, and calculates the evaporation amount of the inert medium 3 from the external temperature To detected by the external temperature measuring section 12 to the cooling heat exchanger 7. Since the amount of condensation of the inert medium 3 is controlled to be smaller than the amount of condensation of the inert medium 3, it is possible to easily prevent the pressure inside the storage box 2 from becoming higher than the predetermined pressure Po.

It also includes a heat controller 9 that is connected to both the pressure measuring section 11 and the cooling heat exchanger 7, and the heat controller 9 controls the pressure inside the storage box 2 measured by the pressure measuring section 11 and the cooling heat. It has a table showing the relationship with the operating power of the exchanger 7, and the cooling heat exchanger 7 is given the operating power W corresponding to the pressure P inside the storage box 2 converted based on the table. Therefore, the cooling heat exchanger 7 can be accurately controlled with the operating power W that corresponds to the pressure P inside the storage box 2.

The storage box 2 is also equipped with a pressure release valve 21 that releases the gas inside the storage box 2 to the outside, and when the pressure inside the storage box 2 is higher than the predetermined pressure Po, Alternatively, in at least one of the cases where the amount of evaporation of the inert medium 3 is greater than the amount of condensation of the inert medium 3 by the cooling heat exchanger 7, the gaseous inert medium 3 inside the storage box 2 is discharged to the outside. Since the pressure P inside the storage box 2 is lowered below the predetermined pressure Po, it is possible to reliably prevent the pressure P inside the storage box 2 from increasing to a dangerous state.

Further, the battery 1 is portable, and the cooling heat exchanger 7 is connected to an external main power source 22 and the battery 1, so that the external main power source 22 is in an uncontrollable state and the battery 1 is in a controllable state. At this time, the power supply source to the cooling heat exchanger 7 is switched from the external main power supply 22 to the battery 1, and the cooling heat exchanger 7 is driven by the power supply from the battery 1, and the cooling heat exchanger 7 is operated. Since the temperature of the inert medium 3 is lowered and the pressure P inside the storage box 2 is lowered than the predetermined pressure Po, even if the external main power source 22 is out of control, the power supply from the battery 1 can be used for cooling. The heat exchanger 7 can be driven.

Further, when both the external main power source 22 and the battery 1 are in an uncontrollable state and the pressure P inside the storage box 2 is higher than the predetermined pressure Po, a pressure release valve is provided that releases the gas inside the storage box 2 to the outside. 21 discharges the gaseous inert medium 3 inside the storage box 2 to the outside and reduces the pressure P inside the storage box 2, so even if both the external main power source 22 and the battery 1 are in an uncontrollable state, , safety can be ensured by the pressure release valve 21.

Moreover, since the storage box 2 includes the filling port 23 for filling the inside of the storage box 2 with the inert medium 3, it is possible to easily fill the sealed storage box with the inert medium.

In addition, since the storage box 2 is provided with a visual confirmation part 24 that allows the user to visually check the amount of liquid inert medium 3 stored inside the storage box 2, the amount of inert medium 3 stored in the storage box 2 can be checked. It can be easily checked.

Further, according to the present embodiment, the battery 1, the sealed storage box 2 that has strength enough to withstand a predetermined pressure Po and houses the battery 1, and the storage section 4 formed inside the storage box 2, In order to move the contained liquid inert medium 3 and the inert medium 3 from the storage section 2 to a heat exchangeable position 6 adjacent to the battery 1 and capable of exchanging heat with the battery 1, A wick 5 as an inert medium moving member is arranged between the storage section 4 in the box 2 and the heat exchangeable position 6, and the inert medium 3 that has been moved to the heat exchangeable position 6 is transferred from the battery 1. A temperature control device for the battery 1 that cools the battery 1 by converting it into a gaseous state through heat transfer includes a pressure measurement unit 11 that measures the pressure P inside the storage box 2, and a pressure measurement unit 11 that measures the pressure P inside the storage box 2 or the inside of the storage box 2. a cooling heat exchanger 7 disposed in a position in contact with the outer wall to cool the inert medium 3; By cooling the storage box 2, the pressure P inside the storage box 2 is lowered from the predetermined pressure Po, so the inert medium 3 inside the storage box 2 and the battery are The heat exchange with the battery 1 can be efficiently controlled, and the temperature of the battery 1 using the inert medium 3 can be controlled more appropriately.

Next, a second embodiment of the present invention will be described with reference to FIG. 4.

The second reference form shown in FIG. 4 mainly includes a sealed storage box 2 that has strength enough to withstand a predetermined pressure Po and houses the battery 1, and a storage section formed inside the storage box 2. 4 and the inert medium 3 is transported from the storage section 4 to a heat exchangeable position 6 adjacent to the battery 1 where heat can be exchanged with the battery 1 in an anti-gravity direction. A temperature control device for the battery 1 includes a wick 5 as an inert medium moving member disposed between the storage section 4 and the heat exchangeable position 6 in the storage box 2 in order to move the battery 1 to the storage box 2. It is equipped with a pressure measurement unit 11 that measures the internal pressure P and a pressure release valve 21 that releases the gas inside the storage box 2 to the outside, and removes the inert medium 3 that has been moved to the heat exchangeable position 6 from the battery 1. This embodiment is similar to the first reference embodiment shown in FIG. 3 in that the battery 1 is cooled by converting it into a gaseous state through heat transfer, but the first reference embodiment does not include the cooling heat exchanger 7. It is different from
Note that although the cooling heat exchanger 7 is not provided, natural heat radiation from the storage box 2 is performed. Furthermore, for natural heat radiation, the storage box may be provided with fins to more efficiently radiate heat.

In this embodiment, even if the cooling heat exchanger 7 is not provided, the liquid inert medium 3 moves to the heat exchangeable position 6 and changes to the gaseous inert medium 3, and the storage box 2 When the internal pressure P becomes higher than the predetermined pressure Po, the pressure release valve 21 discharges the gaseous inert medium 3 to the outside of the storage box 2, thereby eliminating the need to use the cooling heat exchanger 7. Also, the heat exchange between the inert medium 3 in the storage box 2 and the battery 1 can be efficiently controlled while appropriately managing the pressure P inside the storage box 2 with the pressure release valve 21.

Although the first and second embodiments and the first and second reference embodiments of the present invention have been described above, various design changes can be made to the present invention without departing from the gist thereof.

It is also possible to use only the moving member 20. Furthermore, it is also possible to incorporate a part of the configurations of the first and second reference embodiments into the configurations of the first and second embodiments.
