Description

[Technical Field]

[0001] The present disclosure relates to vehicle climate control systems. [Background technology]

[0002] Regarding a temperature control system for a vehicle, Patent Document 1 discloses that heat-generating equipment in a vehicle is cooled by flowing coolant through a hot water circuit that is thermally coupled to the heat-generating equipment. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-79328 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, in vehicle temperature control systems, in order to adjust the temperature of a temperature-control object (for example, a battery mounted on an electric vehicle) to an appropriate temperature, it is sometimes required to not only cool but also heat the temperature-control object using coolant. In such cases, there has been a demand for technology that can adjust the temperature of the temperature-control object with good responsiveness. [Means for solving the problem]

[0005] The present disclosure can be realized in the following forms. According to one aspect of the present disclosure, a temperature control system for a vehicle is provided. The temperature control system includes a first container that contains a temperature control liquid for controlling the temperature of a temperature control object provided in the vehicle; a second container that contains a temperature control liquid at a lower temperature than the temperature control liquid contained in the first container and is different from the first container; a supply flow path that communicates with each of the first container and the second container and is configured to supply the temperature control liquid from the first container and the second container to the temperature control object; and a control unit. The supply flow path includes a first partial flow path that causes the temperature control liquid in the first container to flow from the first container to the temperature control object; a second partial flow path that causes the temperature control liquid in the second container to flow from the second container to the temperature control object and is different from the first partial flow path; and an adjustment unit that is configured to adjust the flow rate of the temperature control liquid flowing through the first partial flow path and the flow rate of the temperature control liquid flowing through the second partial flow path. The first partial flow path and the second partial flow path are configured to merge upstream of the temperature control object. The adjusting unit includes a first valve unit provided in the first partial flow path, a second valve unit provided in the second partial flow path, and a pump unit provided in the supply flow path downstream of a point where the first partial flow path and the second partial flow path join together. The object to be temperature-controlled is a driving battery for driving the vehicle. The control unit, when in a driving state in which the vehicle is driving by the driving battery, controls the adjustment unit based on a temperature obtained using a temperature sensor that measures the temperature of the driving battery, thereby feedback-controlling the temperature of the temperature-control object so that the temperature of the temperature-control object is within a predetermined optimum temperature range; when in a first state of the driving state in which the temperature of the temperature-control object is in a temperature range higher than the optimum temperature range, the control unit closes the first partial flow path and opens the second partial flow path, and controls the drive amount of the pump unit to a first drive amount; and when in a second state of the driving state in which the temperature of the temperature-control object is in a temperature range higher than the first state, the control unit closes the first partial flow path and opens the second partial flow path, and controls the drive amount of the pump unit to a second drive amount that is larger than the first drive amount.

[0006] (1) According to one aspect of the present disclosure, a temperature control system for a vehicle is provided. The temperature control system includes a first container that contains a temperature control liquid for controlling the temperature of a temperature control object provided in the vehicle; a second container that contains the temperature control liquid at a lower temperature than the temperature control liquid contained in the first container and is different from the first container; and a supply flow path that communicates with each of the first container and the second container and is configured to supply the temperature control liquid from the first container and the second container to the temperature control object. The supply flow path includes a first partial flow path that causes the temperature control liquid in the first container to flow from the first container toward the temperature control object; a second partial flow path that causes the temperature control liquid in the second container to flow from the second container toward the temperature control object and is different from the first partial flow path; and an adjustment unit that is configured to adjust the flow rate of the temperature control liquid flowing through the first partial flow path and the flow rate of the temperature control liquid flowing through the second partial flow path. The first partial flow path and the second partial flow path merge upstream of the temperature control object. In this configuration, by adjusting the flow rate of the temperature control liquid flowing through the first partial flow path and the second partial flow path using the adjusting unit, the temperature of the temperature control liquid flowing through the supply flow path toward the temperature control object can be adjusted with good responsiveness, thereby allowing the temperature of the temperature control object to be adjusted with good responsiveness. (2) In the above embodiment, the first container may have a heater that heats the temperature control liquid in the first container. In this embodiment, by heating the temperature control liquid in the first container with the heater, the temperature of the temperature control liquid in the first container can be easily made higher than the temperature of the temperature control liquid in the second container. (3) In the above aspect, a tank having the first storage unit and the second storage unit may be provided, and the first storage unit and the second storage unit may be disposed adjacent to each other via a heat insulating unit that insulates the first storage unit from the second storage unit. In this aspect, the first storage unit and the second storage unit can be disposed compactly, and unintended changes in the temperatures of the temperature regulating liquid in the first storage unit and the temperature regulating liquid in the second storage unit due to heat exchange between the temperature regulating liquid in the first storage unit and the temperature regulating liquid in the second storage unit can be suppressed. (4) In the above aspect, the heat insulating section may have a first air layer disposed between the first storage section and the second storage section. In this aspect, the first air layer can more easily suppress heat exchange between the first temperature regulating liquid and the second temperature regulating liquid. (5) In the above embodiment, the tank may have a heat insulating wall for insulating the inside of the tank from the outside. In this embodiment, it is possible to prevent the temperature of the temperature control liquid in the first storage section and the second storage section from unintentionally changing due to heat exchange with the outside of the tank. (6) In the above embodiment, the insulating wall may be formed to surround the periphery of the tank. In this embodiment, unintended changes in the temperature of the temperature control liquid in the first container and the second container can be more effectively prevented. (7) In the above embodiment, the heat insulating wall may have a double-wall structure having a pair of walls sandwiching a second air layer. In this embodiment, the second heat insulating wall can be configured more simply. (8) In the above aspect, the liquid supply system may further include a third container, different from the first container and the second container, that contains a temperature control liquid having a temperature different from that of the temperature control liquid contained in the first container and the temperature control liquid contained in the second container, the third container being different from the first container and the second container, the supply flow path being in communication with the third container and configured to supply the temperature control liquid from the third container to the object to be temperature-controlled, the temperature control liquid in the third container being caused to flow from the third container toward the object to be temperature-controlled, and a third partial flow path different from the first partial flow path and the second partial flow path, the adjustment unit being configured to adjust the flow rate of the temperature control liquid flowing through the third partial flow path, and the third partial flow path being merged with the first partial flow path and the second partial flow path upstream of the object to be temperature-controlled. In this aspect, by adjusting the flow rate of the temperature control liquid through the third partial flow path in addition to the first partial flow path and the second partial flow path using the adjustment unit, it is easy to adjust the temperature of the temperature control liquid flowing through the supply flow path toward the object to a desired temperature. Therefore, the temperature of the temperature control object can be more appropriately adjusted.

[0007] The present disclosure can be realized in various forms other than the above-described form as a temperature control system for a vehicle, such as a vehicle equipped with a temperature control system. [Brief explanation of the drawings]

[0009] A. First embodiment: 1 is an explanatory diagram showing a schematic configuration of a temperature adjustment system 100 in a first embodiment. The temperature adjustment system 100 is provided in a vehicle Vc, and adjusts the temperature of a temperature adjustment object OB provided in the vehicle Vc by using a temperature adjustment liquid Lq. The temperature adjustment liquid Lq refers to a liquid for adjusting the temperature of the temperature adjustment object OB.

[0010] In this embodiment, the vehicle Vc is configured as a BEV (Battery Electric Vehicle) powered by a drive battery. The temperature control object OB in this embodiment is the battery pack of the vehicle Vc, which has a drive battery configured as a lithium-ion battery. In other embodiments, the vehicle Vc may be, for example, a gasoline vehicle or a diesel vehicle, or may be an HEV (Hybrid Electric Vehicle), a PHEV (Plug-in Hybrid Electric Vehicle), or an FCV (Fuel Cell Vehicle). Furthermore, the temperature control object OB may be, for example, a battery configured as a lead battery, or an engine, motor, inverter, control computer, or any other object mounted on the vehicle Vc.

[0011] The temperature adjustment system 100 in this embodiment includes a tank 101, a circulation circuit 150, and a control unit 300. The circulation circuit 150 includes a supply flow path 155 (described later) and is configured to be able to circulate a temperature adjustment liquid Lq between the tank 101 and the temperature adjustment object OB. In Figure 1, the flow of the temperature adjustment liquid Lq in the circulation circuit 150 is schematically indicated by hollow arrows.

[0012] FIG. 2 is a cross-sectional view showing a schematic configuration of the tank 101 in this embodiment. The tank 101 is configured as a container. The interior of the tank 101 is in communication with the outside through an opening Op formed in a tank upper end 102, which is the upper end of the tank 101. The tank 101 is configured so that a lid 108 that covers the opening Op can be attached and detached. In this embodiment, the tank 101 is arranged so that the opening Op opens vertically upward. As a result, the lid 108 attached to the opening Op is located above the opening Op in the vertical direction. The end of the tank 101 opposite the tank upper end 102 in the direction along the opening direction of the opening Op is also referred to as a bottom 109. In this embodiment, the bottom 109 is located below the tank upper end 102 in the vertical direction.

[0013] The tank 101 has a first storage unit 110 and a second storage unit 120 therein, each storing a temperature control liquid Lq. The first storage unit 110 stores the temperature control liquid Lq in a first internal space 111 formed therein. The second storage unit 120 stores a temperature control liquid Lq having a lower temperature than the first temperature control liquid Lq1 in a second internal space 121 formed therein. Hereinafter, the temperature control liquid Lq stored in the first storage unit 110 will also be referred to as the first temperature control liquid Lq1, and the temperature control liquid Lq stored in the second storage unit 120 will also be referred to as the second temperature control liquid Lq2.

[0014] In this embodiment, the temperature of the first temperature control liquid Lq1 is maintained at, for example, 50°C to 80°C by the first heater 115 and the heating flow path 165 shown in FIG. 1. The temperature of the second temperature control liquid Lq2 is maintained at, for example, -40°C to 0°C when the vehicle Vc is in a sub-zero environment. A sub-zero environment refers to an environment where the outside air temperature is 0°C or lower. The temperatures of the first temperature control liquid Lq1 and the second temperature control liquid Lq2 are acquired by the control unit 300 using, for example, temperature sensors (not shown) provided in the first storage unit 110 and the second storage unit 120. The first heater 115 and the heating flow path 165 will be described in detail below.

[0015] The first internal space 111 communicates with the outside through a first opening Op1 formed in a first upper end 112, which is the upper end of the first storage unit 110. The second internal space 121 communicates with the outside through a second opening Op2 formed in a second upper end 122, which is the upper end of the second storage unit 120. The first opening Op1 and the second opening Op2 are disposed within the opening Op of the tank 101 so as to open vertically upward. The first opening Op1 and the second opening Op2 are opened and closed by attaching and detaching the lid 108. The first opening Op1 and the second opening Op2 are opened, for example, when the temperature control liquid Lq is refilled into the first storage unit 110 or the second storage unit 120 through the first opening Op1 or the second opening Op2.

[0016] In this embodiment, the first storage section 110 and the second storage section 120 are arranged adjacent to each other via a first heat insulating section 140 that insulates the first storage section 110 from the second storage section 120. More specifically, in this embodiment, the first storage section 110, the first heat insulating section 140, and the second storage section 120 are arranged side by side in the horizontal direction. The first heat insulating section 140 in this embodiment has a first air layer AL1 arranged between the first storage section 110 and the second storage section 120, and the first air layer AL1 insulates the first storage section 110 from the second storage section 120. Hereinafter, the first heat insulating section 140 will also be simply referred to as the heat insulating section.

[0017] In this embodiment, the tank 101 has an insulating wall 103 for insulating the inside of the tank 101 from the outside. The insulating wall 103 in this embodiment is formed so as to surround the periphery of the tank 101. More specifically, the insulating wall 103 is formed so as to surround the portion of the tank 101 excluding the upper end portion 102 of the tank.

[0018] In this embodiment, the insulating wall 103 has a double-wall structure including a pair of walls sandwiching a second air layer AL2 therebetween. More specifically, the insulating wall 103 has a first wall 104 facing the first internal space 111, a second wall 105 facing the second internal space 121, and an outer wall 106 disposed outside the first wall 104 and the second wall 105. The first wall 104 and the second wall 105 are disposed with a gap from the outer wall 106 in the thickness direction of the outer wall 106. As a result, a second air layer AL2 is formed between the first wall 104 and the outer wall 106, and between the second wall 105 and the outer wall 106. As a result, in this embodiment, at least a portion of the insulating wall 103 partitions at least a portion of the first storage section 110 and at least a portion of the second storage section 120. More specifically, the heat insulating wall 103 defines the first storage section 110 except for the first upper end 112, and defines the second storage section 120 except for the second upper end 122. In this embodiment, the first upper end 112 is defined only by the first wall 104. The second upper end 122 is defined only by the second wall 105.

[0019] In this embodiment, the outer wall 106 has a folded portion 107. The folded portion 107 extends from the bottom 109 of the tank 101 toward the upper end 102 of the tank and then folds back to extend from the upper end 102 toward the bottom 109. In this embodiment, the folded portion 107 is disposed between the first storage section 110 and the second storage section 120. An air layer is formed between the outer walls 106 that form the folded portion 107. Therefore, in this embodiment, two second air layers AL2 and an air layer sandwiched between the outer walls 106 that form the folded portion 107 are disposed between the first storage section 110 and the second storage section 120. In other words, in this embodiment, it can be said that three first air layers AL1 are disposed between the first storage section 110 and the second storage section 120. In addition, in this embodiment, it can be said that the folded portion 107 functions as a first insulating section 140.

[0020] The first container 110 includes a first heater 115 that heats the first temperature control liquid Lq1. In this embodiment, the first heater 115 is configured as a sheet-like rubber heater and is disposed between the first wall 104 and the second wall 105. More specifically, the first heater 115 is attached to the outside of the first wall 104 so as to cover approximately one-third to one-half of the first internal space 111 in the vertical direction from the bottom 109 side. The temperature of the first heater 115 is controlled by the control unit 300. In other embodiments, the first heater 115 may be configured as an electric wire heater such as a nichrome wire heater. In this case, for example, the electric wire may be embedded in the first wall 104. Furthermore, the first heater 115 does not have to be disposed so as to cover the first internal space 111 from the bottom 109 side, and may be disposed in any manner as long as it can heat the first temperature control liquid Lq1. Hereinafter, the first heater 115 will also be simply referred to as the heater.

[0021] The tank 101 is formed of a resin material such as polypropylene (PP), glass fiber reinforced polypropylene, nylon 66, or glass fiber reinforced nylon 66. The tank 101 having a double-wall structure as in this embodiment is manufactured, for example, by joining multiple parts that constitute the tank 101. More specifically, for example, first, as an upper portion that forms the tank upper end 102 side of the tank 101, a portion for forming the first wall 104, a portion for forming the second wall 105, and a portion for forming the outer wall 106 are individually molded by injection molding. In addition, a lower portion that forms the bottom 109 side of the tank 101 from the upper portion is individually molded for each portion, similar to the upper portion. Next, for example, a first heater 115 is attached to the portion of the lower portion that forms the first wall 104. Then, the portions of the upper and lower sections that form first wall 104, second wall 105, and outer wall 106 are joined together by welding. Depending on the shape of tank 101, the portions of the upper section may be joined together in advance by welding, adhesive, or the like before joining the upper and lower sections. Similarly, the portions of the lower section may be joined together in advance.

[0022] As shown in FIG. 1 , the circulation circuit 150 has a supply flow path 155 and a recovery flow path 180. The supply flow path 155 is connected to each of the first and second storage units 110 and 120, and is configured so that the temperature control liquid Lq can be supplied from the first and second storage units 110 and 120 to the temperature control object OB by flowing the temperature control liquid Lq therethrough. The recovery flow path 180 is connected to each of the first and second storage units 110 and 120, and is configured so that the temperature control liquid Lq can be recovered from the temperature control object OB to the first and second storage units 110 and 120 by flowing the temperature control liquid Lq therethrough. The supply flow path 155 and the recovery flow path 180 are formed, for example, by pipes or hoses. The supply flow path 155 and the recovery flow path 180 may be formed, for example, by metal, resin, or rubber. In this embodiment, the supply flow path 155 and the recovery flow path 180 are formed by a three-layer rubber hose having inner and outer layers made of ethylene propylene diene rubber (EPDM) and a reinforcing layer made of fiber.

[0023] The supply flow path 155 has a first partial flow path 156, a second partial flow path 157 different from the first partial flow path 156, and an adjustment unit 160. The first partial flow path 156 is a flow path that allows the first temperature control liquid Lq1 to flow from the first storage unit 110 toward the temperature control object OB. The second partial flow path 157 is a flow path that allows the second temperature control liquid Lq2 to flow from the second storage unit 120 toward the temperature control object OB. The first partial flow path 156 and the second partial flow path 157 merge upstream of the temperature control object OB in the supply flow path 155. Hereinafter, the portion of the supply flow path 155 downstream of the point where the first partial flow path 156 and the second partial flow path 157 merge will also be referred to as a junction 158. Therefore, both the first temperature control liquid Lq1 and the second temperature control liquid Lq2 can flow through the junction 158.

[0024] The adjustment unit 160 is configured to be able to adjust the flow rate of the temperature adjustment liquid Lq flowing through the first partial flow path 156 and the second partial flow path 157. In this specification, the phrase "adjustable flow rate" does not only mean that the flow rate can be adjusted stepwise or continuously, but also means that the flow rate can simply be switched between a state where the flow rate is zero and a state where the flow rate is greater than zero.

[0025] The adjustment unit 160 in this embodiment includes a first valve unit 161 provided in the first partial flow path 156, a second valve unit 162 provided in the second partial flow path 157, and a pump unit 163 provided in the junction 158. The first valve unit 161 is configured as an electromagnetic on-off valve that opens and closes the first partial flow path 156 under the control of the control unit 300. The second valve unit 162 is configured as an electromagnetic on-off valve that opens and closes the second partial flow path 157 under the control of the control unit 300. Check valves (not shown) are provided in the first partial flow path 156 and the second partial flow path 157, respectively, to prevent the temperature control liquid Lq from flowing toward the first storage unit 110 and the second storage unit 120. The pump unit 163 is configured as an electric water pump that is driven under the control of the control unit 300.

[0026] The recovery flow path 180 is configured as a flow path that branches into two at a first branch point 190 located midway. The recovery flow path 180 has a common flow path 181 that extends from the temperature adjustment object OB toward the first branch point 190, a first recovery flow path 182 for recovering the temperature adjustment liquid Lq into the first storage unit 110, and a second recovery flow path 183 for recovering the temperature adjustment liquid Lq into the second storage unit 120. In this embodiment, the first recovery flow path 182 corresponds to the flow path that connects the first branch point 190 and the first storage unit 110. The second recovery flow path 183 corresponds to the flow path that connects the first branch point 190 and the second storage unit 120.

[0027] A cooling unit 195 for cooling the temperature control liquid Lq is disposed in the common flow path 181. In this embodiment, the cooling unit 195 is configured as a radiator. The cooling capacity of the cooling unit 195 is controlled by controlling the rotation speed of the radiator fan under the control of the control unit 300. In other embodiments, the cooling unit 195 may be disposed, for example, in the second recovery flow path 183, near the second storage unit 120, or near the temperature control target OB in the junction 158. The cooling unit 195 may also be configured as a chiller, for example.

[0028] A third valve unit 186 is disposed in first recovery flow path 182. Third valve unit 186 is configured as an electromagnetic on-off valve that opens and closes first recovery flow path 182 under the control of control unit 300. A fourth valve unit 187 is disposed in second recovery flow path 183. Fourth valve unit 187 is configured as an electromagnetic on-off valve that opens and closes second recovery flow path 183 under the control of control unit 300. Check valves (not shown) are provided in first recovery flow path 182 and second recovery flow path 183, similar to first partial flow path 156 and the like.

[0029] A heating flow path 165 is connected to the first recovery flow path 182 downstream of the third valve unit 186 and the check valve. The heating flow path 165 is thermally coupled to a heater (not shown) for heating the passenger compartment and seats of the vehicle Vc, and supplies the temperature control liquid Lq heated by the heat of the heater to the first accommodation unit 110. Therefore, in this embodiment, the first temperature control liquid Lq1 also includes the temperature control liquid Lq supplied to the first accommodation unit 110 via the heating flow path 165. A fifth valve unit 166 is arranged in the heating flow path 165. The fifth valve unit 166 is configured as an electromagnetic on-off valve that opens and closes the heating flow path 165 under the control of the control unit 300. A check valve (not shown) is arranged in the heating flow path 165, similar to the first partial flow path 156, etc. The temperature control liquid Lq flowing through the heating flow path 165 flows through the first recovery flow path 182 and is supplied to the first accommodation unit 110. The temperature of the temperature adjustment liquid Lq flowing through the heating flow path 165 is acquired by the control unit 300 using a temperature sensor (not shown) provided in the heating flow path 165, for example.

[0030] A bypass flow path BP is connected to the first recovery flow path 182 upstream of the third valve section 186 and the check valve. A bypass valve section BV is arranged in the bypass flow path BP. The bypass valve section BV is configured as an electromagnetic on-off valve that opens and closes the bypass flow path BP under the control of the control section 300. A check valve (not shown) is arranged in the bypass flow path BP, similar to the first partial flow path 156, etc. For example, when the amount of temperature control liquid Lq in the circulation circuit 150 becomes excessive, the control section 300 opens and closes the bypass valve section BV as appropriate, thereby bypassing the temperature control liquid Lq in the circulation circuit 150 to another circuit, etc., via the bypass flow path BP.

[0031] The control unit 300 is configured by a computer having one or more processors, a storage device, and an input / output interface for inputting and outputting signals from and to the outside. The control unit 300 has the function of circulating the temperature control liquid Lq between the tank 101 and the temperature control object OB by controlling the pump unit 163 and various valve units provided in the circulation circuit 150. In other embodiments, the control unit 300 may be configured by, for example, a combination of multiple circuits. Also, for example, a control computer for the vehicle Vc may function as the control unit 300.

[0032] FIG. 3 is an explanatory diagram showing the first control mode of the temperature adjustment system 100. In this embodiment, the control unit 300 controls the temperature adjustment system 100 in the first control mode when the vehicle Vc is in a running state. The "running state" refers to a state in which the vehicle Vc is running by being driven by the driving battery. FIG. 3 shows the temperature state of the temperature adjustment object OB and the control of each unit, such as the first valve unit 161, that is executed in that temperature state.

[0033] State DN shown in FIG. 3 represents a state in which the temperature of the temperature control object OB is in an optimum temperature range while the vehicle Vc is traveling. The optimum temperature range refers to a temperature range that is particularly preferable for the temperature control object OB. In this embodiment, the temperature of the temperature control object OB is, for example, in a temperature range of 20°C or higher and 25°C or lower. States DH1, DH2, and DH3 represent states in which the temperature of the temperature control object OB is in a temperature range higher than the optimum temperature range while the vehicle is traveling. In state DH2, the temperature control object OB is in a temperature range higher than state DH1. In state DH3, the temperature control object OB is in a temperature range higher than states DH2 and DH1. States DL1, DL2, and DL3 represent states in which the temperature of the temperature control object OB is in a temperature range lower than the optimum temperature range while the vehicle is traveling. In state DL2, the temperature control object OB is in a temperature range lower than state DL1. In state DL3, the temperature control object OB is in a temperature range lower than states DL2 and DL1. In this embodiment, the temperature of the temperature adjustment object OB is acquired by the control unit 300 using the temperature sensor 201 attached to the housing of the battery pack shown in Fig. 1. That is, the control unit 300 controls each part such as the first valve unit 161 based on the value of this temperature sensor 201, thereby feedback-controlling the temperature of the temperature adjustment object OB.

[0034] In FIG. 3, the control state of each of the first valve unit 161 to the fifth valve unit 166 is represented by "ON" or "OFF." A "valve unit is OFF" state refers to a state in which the flow path in which the valve unit is provided is fully closed by the valve unit. A "valve unit is ON" state refers to a state in which the flow path in which the valve unit is provided is fully open. Also, in FIG. 3, the magnitude of the drive amount of the pump unit 163 is represented by a numerical value from 0 to 10. The larger this numerical value, the greater the drive amount of the pump unit 163. In FIG. 3, a drive amount of the pump unit 163 of 0 indicates that the pump unit 163 is stopped. Also, in FIG. 3, the degree of temperature rise of the first temperature control liquid Lq1 due to temperature rise control is represented by a numerical value from 0 to 10. Temperature rise control refers to control by the control unit 300 to increase the temperature of the first temperature control liquid Lq1. The larger this numerical value, the more accelerated the temperature rise of the first temperature control liquid Lq1 is. In this embodiment, the control unit 300 performs at least one of the following in temperature rise control: turning on the first heater 115; or turning on the fifth valve unit 166 when the temperature of the first temperature adjustment liquid Lq1 is lower than the temperature of the temperature adjustment liquid Lq in the heating flow path 165. In Fig. 3, the degree of temperature rise in temperature rise control being 0 indicates that temperature rise control is not being performed, that is, the first heater 115 is OFF and the fifth valve unit 166 is OFF.

[0035] As shown in FIG. 3 , in state DN, the control unit 300 turns on the second valve unit 162 and the fourth valve unit 187 and turns off the first valve unit 161 and the third valve unit 186. The control unit 300 also sets the drive amount of the pump unit 163 to zero or a drive amount slightly greater than zero, depending on, for example, the amount of power supplied from the drive battery to the drive unit of the vehicle Vc. Through the above control, in state DN, only the second temperature control liquid Lq2 circulates through the circulation circuit 150. In state DN, for example, if the temperature of the first temperature control liquid Lq1 is lower than a predetermined reference temperature, the control unit 300 may execute temperature increase control. This allows the temperature of the first temperature control liquid Lq1 to be increased so that it approaches the reference temperature. The reference temperature is determined, for example, based on the outside air temperature, as a temperature at which the first temperature control liquid Lq1 can effectively heat the temperature-controlled object OB, whose temperature has dropped.

[0036] In states DH1 to DH3, the control unit 300 controls each valve unit in the same manner as in state DN. Furthermore, the control unit 300 increases the drive amount of the pump unit 163 compared to the drive amount in state DN. More specifically, the control unit 300 controls the drive amount of the pump unit 163 so that it increases in the order of states DH1, DH2, and DH3. For example, the control unit 300 may control the cooling capacity of the cooling unit 195 so that it increases in the order of states DH1, DH2, and DH3. It is preferable that the drive amount of the pump unit 163 and the cooling capacity of the cooling unit 195 in states DH1 to DH3 be controlled so that the temperature control object OB can be appropriately cooled in each of states DH1 to DH3. As a result, in states DH1 to DH3, only the second temperature control liquid Lq2 circulates within the circulation circuit 150, similar to state DN. Furthermore, by controlling the pump unit 163 and the cooling unit 195, the higher the temperature of the temperature adjustment target OB, the more the second temperature adjustment liquid Lq2 is supplied to the temperature adjustment target OB, and the more the cooling of the second temperature adjustment liquid Lq2 by the cooling unit 195 is promoted. Therefore, the higher the temperature of the temperature adjustment target OB, the more the cooling of the temperature adjustment target OB by the second temperature adjustment liquid Lq2 is promoted. Note that in states DH1 to DH3, the control unit 300 may execute temperature increase control, similar to the case in state DN.

[0037] In states DL1 to DL3, the control unit 300 turns on the first valve unit 161 and at least one of the third valve unit 186 and the fifth valve unit 166, while turning off the other valve units. The control unit 300 increases the amount of heat applied to the first temperature control liquid Lq1 in the order of states DL1, DL2, and DL3. More specifically, when the fifth valve unit 166 is not turned on during temperature increase control, the control unit 300 turns on the third valve unit 186. When the fifth valve unit 166 is turned on during temperature increase control, the control unit 300 may turn on or off the third valve unit 186. When the fifth valve unit 166 is turned on, turning off the third valve unit 186 prevents the temperature control liquid Lq from flowing into the first container 110 via the first recovery passage 182, thereby increasing the temperature of the first temperature control liquid Lq1. Furthermore, in states DL1 to DL3, the control unit 300 increases the drive amount of the pump unit 163 compared to the drive amount in state DN. More specifically, the control unit 300 increases the drive amount of the pump unit 163 in the order of states DL1, DL2, and DL3. As a result, in states DL1 to DL3, only the first temperature control liquid Lq1 flows through the supply flow path 155. Furthermore, the first temperature control liquid Lq1 is heated by the temperature increase control. Furthermore, by controlling the pump unit 163 as described above, the lower the temperature of the temperature control target OB, the more the first temperature control liquid Lq1 is supplied to the temperature control target OB. Therefore, the lower the temperature of the temperature control target OB, the more the heating of the temperature control target OB by the first temperature control liquid Lq1 is promoted. In states DL1 to DL3, particularly when the third valve unit 186 is turned ON, it is preferable to control the cooling capacity of the cooling unit 195 to be lower than in states DH1 to DH3. For example, in states DL1 to DL3, the driving of the radiator fan of the cooling unit 195 may be stopped.

[0038] FIG. 4 is an explanatory diagram showing the second control mode of the temperature adjustment system 100. In this embodiment, the control unit 300 controls the temperature adjustment system 100 in the second control mode when the vehicle Vc is in a stopped state. The stopped state refers to a state in which the vehicle Vc is stopped and not running while the main power supply of the vehicle Vc is ON, and includes, for example, a state before the vehicle starts running, a state in which the vehicle Vc is temporarily stopped while running, and a charging state in which the drive battery of the battery pack is being charged. Like FIG. 3, FIG. 4 shows the temperature state of the temperature adjustment object OB and the control of each unit, such as the first valve unit 161, that is executed in that temperature state.

[0039] 4 indicates a state in which the temperature of the temperature control object OB is within the optimum temperature range when the vehicle Vc is stopped. Stop In the state SH1, the temperature of the temperature control target OB is in a temperature range higher than the optimum temperature range. In state SH2, the temperature of the temperature control target OB is in a temperature range higher than state SH1. In state SH3, the temperature of the temperature control target OB is in a temperature range higher than states SH2 and SH1. States SL1, SL2, and SL3 represent states in the stopped state where the temperature of the temperature control target OB is in a temperature range lower than the optimum temperature range. In state SL2, the temperature control target OB is in a temperature range lower than state SL1. In state SL3, the temperature control target OB is in a temperature range lower than states SL2 and SL1. In this embodiment, the temperature ranges of the temperature control target OB in states SH1 to SH3 are the same as the temperature ranges of the temperature control target OB in states DH1 to DH3, respectively, but may be different from each other. Furthermore, the temperature ranges of the temperature control target OB in states SL1 to SL3 are the same as the temperature ranges of the temperature control target OB in states DL1 to DL3, respectively, but may be different from each other.

[0040] 4, in state SN, the control unit 300 turns off the first valve unit 161 to the fourth valve unit 187. The control unit 300 also sets the drive amount of the pump unit 163 to zero. In state SN, the control unit 300 may execute temperature increase control when the temperature of the first temperature adjustment liquid Lq1 is lower than the reference temperature, as in state DN. However, by not executing temperature increase control even when the temperature of the first temperature adjustment liquid Lq1 is lower than the reference temperature in state SN, it is possible to reduce power consumption of the driving battery in a stopped state.

[0041] In states SH1 to SH3, the control unit 300 turns on the second valve unit 162 and the fourth valve unit 187 and turns off the first valve unit 161 and the third valve unit 186, similarly to states DH1 to DH3. The control unit 300 also increases the drive amount of the pump unit 163 in the order of states SH1, SH2, and SH3. As a result, in states SH1 to SH3, the temperature control object OB is cooled by the second temperature control liquid Lq2, similarly to states DH1 to DH3. In this embodiment, the drive amount of the pump unit 163 in state SH1 is zero. As shown in FIGS. 3 and 4, the drive amount of the pump unit 163 in state SH2 is smaller than the drive amount of the pump unit 163 in state DH2, and the drive amount of the pump unit 163 in state SH3 is smaller than the drive amount of the pump unit 163 in state DH3. This reduces the power consumption of the driving battery due to the drive of the pump unit 163 in the stopped state. In other embodiments, for example, the drive amount of the pump unit 163 in state SH2 may be equal to or greater than the drive amount of the pump unit 163 in state DH2. Also, the drive amount of the pump unit 163 in state SH3 may be equal to or greater than the drive amount of the pump unit 163 in state DH3.

[0042] In states SL1 to SL3, the control unit 300 turns on the first valve unit 161 and at least one of the third valve unit 186 and the fifth valve unit 166, and turns off the other valve units, similarly to states DL1 to DL3. The control unit 300 also controls the heating amount of the first temperature control liquid Lq1 so that it increases in the order of states SL1, SL2, and SL3. The control unit 300 also controls the drive amount of the pump unit 163 so that it increases in the order of states DL1, DL2, and DL3. As a result, in states SL1 to SL3, the temperature control target OB is heated by the first temperature control liquid Lq1, similarly to states DL1 to DL3. In this embodiment, the drive amount of the pump unit 163 in state SL1 is zero. 3 and 4, the drive amount of pump unit 163 in state SL2 is smaller than the drive amount of pump unit 163 in state DL2, and the drive amount of pump unit 163 in state SL3 is smaller than the drive amount of pump unit 163 in state DL3. This makes it possible to reduce power consumption of the driving battery due to drive of pump unit 163 in the stopped state. In other embodiments, for example, the drive amount of pump unit 163 in state SL2 may be equal to or greater than the drive amount of pump unit 163 in state DL2. Furthermore, the drive amount of pump unit 163 in state SL3 may be equal to or greater than the drive amount of pump unit 163 in state DL3.

[0043] The first control mode and the second control mode described above are each an example of control of the temperature regulation system 100. Therefore, for example, the control unit 300 may have another control mode in addition to or in addition to the first control mode and the second control mode. For example, the control unit 300 may control the temperature regulation system 100 in different control modes during normal driving when the vehicle Vc is traveling at a speed lower than a predetermined reference speed (e.g., 80 km / h) and during high-speed driving when the vehicle Vc is traveling at a speed equal to or higher than the reference speed. The control unit 300 may also have a control mode corresponding to "starting" when the vehicle Vc switches from a stopped state to a running state. The control unit 300 may also be configured to use different control modes, for example, during a stopped state in which the vehicle Vc is temporarily stopped and during a charging state.

[0044] According to the temperature adjustment system 100 for the vehicle Vc in this embodiment described above, the supply flow path 155 includes a first partial flow path 156 that allows the first temperature adjustment liquid Lq1 to flow from the first storage unit 110 toward the temperature adjustment object OB, a second partial flow path 157 that allows the second temperature adjustment liquid Lq2 to flow from the second storage unit 120 toward the temperature adjustment object OB, and an adjustment unit 160 that is configured to adjust the flow rate of the temperature adjustment liquid flowing through the first partial flow path 156 and the second partial flow path 157. The first partial flow path 156 and the second partial flow path 157 merge in the supply flow path 155 upstream of the temperature adjustment object OB. Thus, by adjusting the flow rate of the temperature adjustment liquid Lq flowing through the first partial flow path 156 and the second partial flow path 157 using the adjustment unit 160, the temperature of the temperature adjustment liquid Lq flowing through the supply flow path 155 toward the temperature adjustment object OB can be adjusted with good responsiveness. Therefore, the temperature of the temperature control object OB can be adjusted with good responsiveness.

[0045] Furthermore, in this embodiment, because the first partial flow path 156 and the second partial flow path 157 merge, it is possible to shorten the overall length of the piping that forms the flow path of the temperature control liquid Lq and reduce the number of components, such as pumps, that are arranged in the flow path, compared to when, for example, the flow path that flows the first temperature control liquid Lq1 toward the temperature control object OB and the flow path that flows the second temperature control liquid Lq2 toward the temperature control object OB are configured as separate flow paths that do not merge. This makes it easier to achieve space savings and a simpler configuration for the temperature adjustment system 100.

[0046] Furthermore, in this embodiment, the first container 110 has a first heater 115 that heats the first temperature control liquid Lq1. Therefore, by heating the first temperature control liquid Lq1 with the first heater 115, the temperature of the first temperature control liquid Lq1 can be easily made higher than the temperature of the second temperature control liquid Lq2.

[0047] Furthermore, this embodiment includes a tank 101 having a first storage section 110 and a second storage section 120, and the first storage section 110 and the second storage section 120 are disposed adjacent to each other via a first insulating section 140. This allows the first storage section 110 and the second storage section 120 to be disposed compactly, and prevents the temperatures of the first temperature adjustment liquid Lq1 and the second temperature adjustment liquid Lq2 from unintentionally changing due to heat exchange between the first temperature adjustment liquid Lq1 and the second temperature adjustment liquid Lq2.

[0048] Furthermore, in this embodiment, the first heat insulating section 140 has a first air layer AL1 disposed between the first storage section 110 and the second storage section 120. Therefore, the first air layer AL1 can more easily suppress heat exchange between the first temperature adjustment liquid Lq1 and the second temperature adjustment liquid Lq2.

[0049] Furthermore, in this embodiment, the tank 101 has a heat insulating wall 103 for insulating the inside of the tank 101 from the outside. Therefore, it is possible to prevent the temperatures of the first temperature control liquid Lq1 and the second temperature control liquid Lq2 in the tank 101 from unintentionally changing due to heat exchange with the outside of the tank 101.

[0050] Furthermore, in this embodiment, the insulating wall 103 is formed to surround the periphery of the tank 101. Therefore, it is possible to more effectively prevent the temperatures of the first temperature control liquid Lq1 and the second temperature control liquid Lq2 in the tank 101 from unintentionally changing due to heat exchange with the outside of the tank 101.

[0051] Furthermore, in this embodiment, at least a portion of the insulating wall 103 defines at least a portion of the first storage section 110. This allows the tank 101 to be configured more compactly, and also prevents the temperature of the first temperature control liquid Lq1 from unintentionally changing due to heat exchange with the outside.

[0052] In this embodiment, the heat insulating wall 103 has a double-wall structure having a pair of walls sandwiching the second air layer AL2, which makes it possible to configure the heat insulating wall 103 more simply.

[0053] B. Second embodiment: FIG. 5 is an explanatory diagram showing the schematic configuration of a temperature adjustment system 100b in the second embodiment. In FIG. 5, as in FIG. 1, the flow of temperature adjustment liquid Lq is schematically indicated by outlined arrows. Unlike the first embodiment, the temperature adjustment system 100b in this embodiment includes a third container 130. Furthermore, the supply flow path 155b in this embodiment has a third partial flow path 159. Portions of the configuration of the temperature adjustment system 100b in the second embodiment that are not particularly described are the same as those in the first embodiment.

[0054] 6 is a cross-sectional view showing a schematic configuration of the tank 101b in this embodiment. In this embodiment, the third container 130 is disposed in the tank 101b, similar to the first container 110 and the second container 120. The third container 130 is a container different from the first container 110 and the second container 120. The third container 130 contains a temperature control liquid Lq in a third internal space 131 formed therein, the temperature control liquid Lq being at a temperature different from that of the first temperature control liquid Lq1 and the second temperature control liquid Lq2. Hereinafter, the temperature control liquid Lq contained in the third container 130 will also be referred to as the third temperature control liquid Lq3.

[0055] In this embodiment, the temperature of the second temperature control liquid Lq2 is maintained higher than the temperature of the second temperature control liquid Lq2 in the first embodiment by a second heater 125 provided in the second storage section 120. The second heater 125 is configured, for example, by a heater similar to the first heater 115. In this embodiment, the temperature of the third temperature control liquid Lq3 is lower than the temperature of the second temperature control liquid Lq2. More specifically, the temperature of the third temperature control liquid Lq3 is maintained at approximately the same temperature as the second temperature control liquid Lq2 in the first embodiment.

[0056] The third internal space 131 communicates with the outside via a third opening Op3 formed in a third upper end 132, which is the upper end of the third storage unit 130. The third opening Op3 is disposed within the opening Op of the tank 101 so as to open vertically upward. The third opening Op3 is opened and closed by attaching and detaching the lid 108. The third opening Op3 is opened, for example, when the temperature control liquid Lq is replenished into the third storage unit 130 via the third opening Op3.

[0057] In this embodiment, the third storage section 130 is disposed on the opposite side of the first storage section 110, with the second storage section 120 sandwiched between them. The third storage section 130 and the second storage section 120 are disposed adjacent to each other via a second insulating section 145 that insulates the third storage section 130 from the second storage section 120. That is, in this embodiment, the first storage section 110, the first insulating section 140, the second storage section 120, the second insulating section 145, and the third storage section 130 are disposed linearly side by side along the horizontal direction. In this embodiment, the tank 101b has a folded section 107 between the first storage section 110 and the second storage section 120, as well as between the second storage section 120 and the third storage section 130. In this embodiment, the folded section 107 between the second storage section 120 and the third storage section 130 functions as the second insulating section 145 having an air layer. Furthermore, the heat insulating wall 103b in this embodiment has a third wall 133 facing the third internal space 131. A second air layer AL2 is formed between the third wall 133 and the outer wall 106b. The tank 101b is manufactured, for example, in the same manner as the tank 101 described in the first embodiment, by joining multiple parts that make up the tank 101b by welding or the like.

[0058] 5, the supply flow path 155b of the circulation circuit 150b in this embodiment is connected to the third storage section 130 in addition to the first storage section 110 and the second storage section 120, and is configured to be able to supply the temperature adjustment liquid Lq from the third storage section 130 to the temperature adjustment object OB. Furthermore, the recovery flow path 180b is connected to the third storage section 130 in addition to the first storage section 110 and the second storage section 120, and is configured to be able to recover the temperature adjustment liquid Lq from the temperature adjustment object OB to the third storage section 130.

[0059] More specifically, the supply flow path 155b has a third partial flow path 159 in addition to the first partial flow path 156 and the second partial flow path 157. The third partial flow path 159 is a flow path different from the first partial flow path 156 and the second partial flow path 157, and is a flow path that flows the third temperature adjustment liquid Lq3 from the third storage unit 130 toward the temperature adjustment target OB. The third partial flow path 159 merges with the first partial flow path 156 and the second partial flow path 157 upstream of the temperature adjustment target OB in the supply flow path 155b. More specifically, in this embodiment, the third partial flow path 159 merges with the second partial flow path 157 and then with the first partial flow path 156. Therefore, in this embodiment, the first temperature adjustment liquid Lq1, the second temperature adjustment liquid Lq2, and the third temperature adjustment liquid Lq3 can flow through the junction 158b.

[0060] The adjustment unit 160b is configured to be able to adjust the flow rate of the temperature control liquid Lq flowing through the third partial flow path 159, in addition to the flow rate of the temperature control liquid Lq flowing through the first partial flow path 156 and the second partial flow path 157. The adjustment unit 160b has a sixth valve unit 164 provided in the third partial flow path 159, in addition to the first valve unit 161, the second valve unit 162, and the pump unit 163 described in the first embodiment. The sixth valve unit 164 is configured as an electromagnetic on-off valve that opens and closes the third partial flow path 159 under the control of the control unit 300. A check valve (not shown) is arranged in the third partial flow path 159.

[0061] In this embodiment, the recovery flow path 180b is configured as a flow path that branches at a first branch point 190 and then further branches at a second branch point 191. In this embodiment, the recovery flow path 180b has, in addition to the common flow path 181, the first recovery flow path 182, and the second recovery flow path 183b, a connection flow path 185 that connects the first branch point 190 and the second branch point 191, and a third recovery flow path 184 for recovering the temperature control liquid Lq to the third container 130. In this embodiment, the second recovery flow path 183b corresponds to the flow path that connects the second branch point 191 and the second container 120. The third recovery flow path 184 corresponds to the flow path that connects the second branch point 191 and the third container 130. A seventh valve unit 189 is disposed in the third recovery flow path 184. The seventh valve unit 189 is configured as an electromagnetic on-off valve that opens and closes the third recovery flow path 184 under the control of the control unit 300. The third recovery passage 184 is provided with a check valve (not shown).

[0062] The temperature adjustment system 100b according to the second embodiment described above includes the third container 130, and the supply flow path 155b has a third partial flow path 159 that allows the third temperature adjustment liquid Lq3 to flow from the third container 130 toward the temperature adjustment target OB. The adjustment unit 160b is configured to adjust the flow rate of the temperature adjustment liquid Lq flowing through the third partial flow path 159. The third partial flow path 159 merges with the first partial flow path 156 and the second partial flow path 157 in the supply flow path 155b upstream of the temperature adjustment target OB. Therefore, by adjusting the flow rate of the temperature adjustment liquid Lq flowing through the third partial flow path 159 in addition to the first partial flow path 156 and the second partial flow path 157 using the adjustment unit 160b, it is easy to adjust the temperature of the temperature adjustment liquid Lq flowing through the supply flow path 155b toward the temperature adjustment target OB to a desired temperature. For example, in this embodiment, since the temperature of the third temperature control liquid Lq3 is lower than the temperature of the second temperature control liquid Lq2, when the temperature of the temperature control object OB rises rapidly, the temperature of the temperature control object OB can be lowered more rapidly by increasing the flow rate of the temperature control liquid Lq flowing through the third partial flow path 159. In this way, the temperature of the temperature control object OB can be more appropriately adjusted.

[0063] In other embodiments, the temperature of the third temperature control liquid Lq3 may be, for example, higher than the temperature of the first temperature control liquid Lq1, or may be lower than the temperature of the first temperature control liquid Lq1 and higher than the temperature of the second temperature control liquid Lq2. When the first to third storage units 110 to 130 are arranged linearly, as in this embodiment, it is preferable to arrange the first to third storage units 110 to 130 so that a storage unit containing a temperature control liquid Lq of an intermediate temperature is sandwiched between a storage unit containing a higher-temperature temperature control liquid Lq and a storage unit containing a lower-temperature temperature control liquid Lq. The first to third storage units 110 to 130 do not have to be arranged linearly; for example, one storage unit may be arranged adjacent to two other storage units. The temperature adjustment system 100 may also include, for example, four or more storage units containing temperature control liquids Lq of different temperatures.

[0064] C. Third embodiment: FIG. 7 is a cross-sectional view showing a schematic configuration of a tank 101c in the third embodiment. In this embodiment, unlike the first embodiment, the outer wall 106c of the insulating wall 103c does not have a folded portion 107. As a result, in this embodiment, the bottom 109b of the tank 101c is formed to extend uniformly along a horizontal plane. Furthermore, in this embodiment, the air layer formed between the first storage section 110 and the second storage section 120, more specifically, the air layer formed between the opposing first wall 104 and second wall 105, forms the first air layer AL1 of the first insulating section 140b. Portions of the configuration of the temperature adjustment system 100 in the third embodiment that are not specifically described are the same as those in the first embodiment.

[0065] According to the third embodiment described above, the first air layer AL1 in the first heat insulating section 140b can also more easily suppress heat exchange between the first temperature regulating liquid Lq1 and the second temperature regulating liquid Lq2.

[0066] D. Other Embodiments: (D1) In the above embodiment, the first valve section 161 is configured as an on-off valve that simply opens and closes the first partial flow path 156. In contrast, the first valve section 161 may be configured, for example, as a valve that can adjust the opening degree of the first partial flow path 156 in a stepwise or stepless manner. Similarly, each of the second valve section 162 to the seventh valve section 189 may be configured as a valve that can adjust the opening degree of the flow path in which each valve section is provided. In this case, when adjusting the temperature of the temperature adjustment target OB, the control section 300 may not only switch between opening and closing each valve section, but also adjust the opening degree of the flow path in which each valve section is provided. Furthermore, the supply flow path 155 does not necessarily have to be provided with the first valve unit 161 and the second valve unit 162. For example, a single valve unit may be disposed at the junction of the first partial flow path 156 and the second partial flow path 157, the valve unit being configured to be capable of closing the first partial flow path 156 and opening the second partial flow path 157, and to be capable of opening the first partial flow path 156 and closing the second partial flow path 157. In this way, each valve unit may be configured to function as one or more other valve units. Furthermore, for example, two or more valve units may be configured to operate in conjunction with each other.

[0067] (D2) In the above embodiment, the first container 110 is provided with the first heater 115. However, if the temperature of the first temperature control liquid Lq1 can be made higher than the temperature of the second temperature control liquid Lq2, the first container 110 does not need to be provided with a heater. For example, the first recovery flow path 182 or the heating flow path 165 may be provided with a heater that heats the temperature control liquid Lq in each flow path. Furthermore, for example, the temperature of the first temperature control liquid Lq1 may be increased only by the heating flow path 165. Similarly, if the temperature of the first temperature control liquid Lq1 can be made higher than the temperature of the second temperature control liquid Lq2, the heating flow path 165 does not need to be provided.

[0068] (D3) In the above embodiment, the first storage unit 110 and the second storage unit 120 are arranged side by side in the horizontal direction, but they do not have to be arranged in this manner. For example, the first storage unit 110 and the second storage unit 120 may be arranged side by side in the vertical direction. In this case, for example, it is preferable that the first opening Op1 and the second opening Op2 are arranged in positions that can prevent unintended outflow of the temperature control liquid Lq from the first storage unit 110 and the second storage unit 120.

[0069] (D4) In the above embodiment, the first storage section 110 and the second storage section 120 are disposed inside the same tank 101. However, the first storage section 110 and the second storage section 120 do not have to be disposed inside the same tank 101. For example, the first storage section 110 and the second storage section 120 may be configured as separate tanks. In this case, it is preferable that at least the first storage section 110 has an insulating wall that insulates the inside and outside of the first storage section 110. In addition, in this case, the first insulating section 140 does not have to be disposed between the first storage section 110 and the second storage section 120.
