Abstract
An embodiment of the present disclosure relates to a construction machine and a heat management device installed therein. The construction machine comprises: a power supply device that provides power to the construction machine; a hydraulic oil cooling device that cools hydraulic oil for operating the construction machine; an indoor temperature control device that supplies cooled or heated air to an operator; and a heat management device which controls the temperature of the power supply device by using the hydraulic oil that flows into the hydraulic oil cooling device or through heat exchange with the indoor temperature control device, wherein a fluid passes through the inside of the heat management device.
Claims16
A construction machine comprising:
- a power unit configured to provide power to the construction machine;
- a hydraulic oil cooling device configured to cool hydraulic oil for operating the construction machine;
- an interior temperature control device configured to supply cooled or heated air to an operator;
- and
- a heat management device through which fluid passes and which controls temperature of the power unit through heat exchange with hydraulic fluid flowing into the hydraulic fluid cooling device or with the interior temperature control device.
A construction machine comprising:
- a power unit configured to provide power to the construction machine;
- an interior temperature control device including a heater core capable of supplying heated air into a cabin by operating during heating and a cooling member capable of supplying cooled air into the cabin by operating during cooling;
- and
- a heat management device configured to control temperature of the power unit by exchanging heat with a refrigerant flowing into the cooling member during cooling and by supplying fluid, which has passed through the heater core, during heating.
A heat management device that is installed in a construction machine including a power unit configured to provide power to the construction machine, a hydraulic oil cooling device being operated by the power unit and configured to cool hydraulic oil for operating the construction machine, and an interior temperature control device capable of controlling temperature of the inside of a cabin, and that controls temperature of the power unit, the heat management device comprising:
- a heating unit capable of increasing the temperature of the power unit by recovering thermal energy during heating by the interior temperature control device;
- a cooling unit configured to reduce the temperature of the power unit by exchanging thermal energy with a refrigerant of the interior temperature control device;
- and
- a first valve configured to control the temperature of the power unit by selectively controlling flow of fluid passing through the heating unit or the cooling unit.
