The battery temperature regulating device includes a heat transfer unit that transfers heat of a part of the battery groups to another battery group. | 02-06-2014 |
20140041826 | VEHICLE TEMPERATURE CONTROL APPARATUS AND IN-VEHICLE THERMAL SYSTEM - A vehicle temperature control apparatus for controlling temperature of a temperature control object, which is at least one of inside air of a vehicle compartment and a vehicle component, includes a heat capacitive element capable of storing heat, a refrigeration cycle in which heat is absorbed from a low temperature side and is dissipated to a high temperature side, a heat exchanger that causes the heat capacitive element to exchange heat with refrigerant of the refrigeration cycle, and a heat dissipation portion which dissipates heat in the refrigerant of the refrigeration cycle to the temperature control object. Thus, a temperature control by using the heat capacitive element can be effectively performed. | 02-13-2014 |
20140374081 | VEHICLE THERMAL MANAGEMENT SYSTEM - A heat medium discharge side of a first pump and a heat medium discharge side of a second pump are connected to a first switching valve in parallel with each other. Respective heat medium inlet sides of a plurality of temperature adjustment devices are connected to the first switching valve in parallel with each other.

A heat medium suction side of the first pump and a heat medium suction side of the second pump are connected to the second switching valve in parallel with each other. Each of the temperature adjustment devices is switched between a state in which the heat medium circulates between the device and the first pump, and another state in which the heat medium circulates between the device and the second pump. | 12-25-2014 |
20150017492 | TEMPERATURE REGULATION DEVICE - A heat pump cycle includes a refrigerant circuit and a coolant circuit. A first heat exchanger and a second heat exchanger are disposed between the refrigerant circuit and the coolant circuit. The first heat exchanger includes an exterior heat exchanger that functions as an evaporator in a heating operation, and a radiator for radiating heat of a coolant. The second heat exchanger transmits a heat of high-pressure refrigerant to the coolant in the heating operation. A temperature of refrigerant within the second heat exchanger is higher than a temperature of refrigerant within the first heat exchanger. The heat obtained from the second heat exchanger is supplied to the first heat exchanger through the coolant. Further, the heat obtained from the second heat exchanger is stored in the coolant. In defrosting operation, the coolant that has stored the heat therein is supplied to the first heat exchanger. | 01-15-2015 |
20150017495 | BATTERY TEMPERATURE REGULATING DEVICE - A battery temperature regulating device includes batteries, inter-battery passages, and a fluid driving device. The batteries are connected to be capable of energization and arranged in a stacking manner. Each of the inter-battery passages is defined between corresponding adjacent two of the batteries. The fluid driving device is configured to flow temperature regulating fluid for regulating temperature of the batteries through the inter-battery passages. Each of the inter-battery passages includes a first inter-battery passage and a second inter-battery passage. Between the corresponding adjacent two of the batteries, a direction in which temperature regulating fluid flows into the first inter-battery passage and a direction in which temperature regulating fluid flows into the second inter-battery passage are different from each other. A flow direction of temperature regulating fluid flowing through the first inter-battery passage is opposite from a flow direction of temperature regulating fluid flowing through the second inter-battery passage. | 01-15-2015 |
20150101789 | THERMAL MANAGEMENT SYSTEM FOR VEHICLE - First circulation portions switch a flow of a heat medium such that one of the heat media for two systems selectively circulates through a radiator flow path or a first bypass flow path. Second circulation portions switch the flow of the heat medium such that the heat media for the two systems selectively circulate with respect to a second flow path group. The first circulation portions and the second circulation portions are adapted to switch the flow of the heat medium so as to form a first circulation circuit for allowing the heat medium to circulate among a first flow path group, the second flow path group, and a first pump, as well as a second circulation circuit for allowing the heat medium to circulate among the first flow path group, the second flow path group, and a second pump. | 04-16-2015 |
20150121939 | REFRIGERATION CYCLE DEVICE - When a refrigerant flow-path switch performs switching to a first refrigerant flow path, an interior condenser heating air blown into an interior as a first temperature-adjustment subject and an auxiliary heat exchanger are connected in parallel, and the auxiliary heat exchanger heats air blown to a battery as a second temperature-adjustment subject. In contrast, when the refrigerant flow-path switch performs switching to a second refrigerant flow path, an interior evaporator cooling air blown into the interior and the auxiliary heat exchanger are connected in parallel, and the auxiliary heat exchanger cools the air blown to the battery. With this arrangement, one common auxiliary heat exchanger can cool or heat the air for the battery, thereby leading to reduction in size of an entire refrigeration cycle device. | 05-07-2015 |
20150128632 | VEHICULAR THERMO-CONTROL DEVICE - A vehicular thermo-control device adjusts a temperature of a battery. The device has a primary system through which cooling water circulates, and a secondary system through which a refrigerant circulates. The primary system has a heat exchanger which performs heat exchange between the battery and the cooling water, and a heat exchanger which performs heat exchange between the cooling water and an ambient air. The secondary system is a refrigerating cycle. Both heat exchangers on a high temperature side and a low temperature side of the refrigerating cycle are thermally coupled with the primary system. Only one heat exchanger provides heat exchange with the ambient air. The pump of the primary system can switch circulating direction of the cooling water. A controller controls devices to perform cooling and heating operation. | 05-14-2015 |
