Abstract
This application relates to a cooling device that sprays a coolant received from a coolant reservoir toward a target region to cool the target region. In one aspect, the cooling device includes a spraying unit from which the coolant is sprayed, a valve configured to regulate a flow of the coolant, and a control unit configured to control opening and closing of the valve, wherein, when cooling starts. The control unit controls a first cooling mode in which a temperature of the target region is decreased and a second cooling mode in which the temperature of the target region is maintained in a predetermined temperature range to be sequentially performed.
Claims10
A hand-held device for spraying a coolant to a target area, comprising:
- a coolant storing unit configured to store the coolant;
- a nozzle configured to provide a pathway of the coolant, transferred from the coolant storing unit, to an external space of the hand-held device;
- a valve disposed between the coolant storing unit and the nozzle and configured to control a flow of the coolant based on an electrical signal;
- a temperature sensor configured to sense a temperature of the target area;
- and
- a controller configured to set a cooling mode of the hand-held device as a first cooling mode or a second cooling mode according to the sensed temperature of the target area, and to apply the electrical signal to the valve such that the valve is fully-opened and then fully-closed repeatedly according to a predetermined time gap of the cooling mode,
- wherein, when the hand-held device is in the first cooling mode, the controller receives the sensed temperature of the target area consecutively,
- wherein, when the sensed temperature of the target area is equal to or less than a first criterion value, the controller changes the cooling mode from the first cooling mode to the second cooling mode,
- wherein, at the first cooling mode, the valve is controlled to open per a first time gap such that a first plurality of cooling pulses with the first time gap are generated,
- wherein, at the second cooling mode, the valve is controlled to open per a second time gap such that a second plurality of cooling pulses with the second time gap are generated, and
- wherein the first time gap is shorter than a second time gap such that an average change rate of the temperature of the target area over the second plurality of cooling pulses in the second cooling mode is smaller than an average change rate of the temperature of the target area over the first plurality of cooling pulses in the first cooling mode.
