Abstract

There is provided a flight vehicle including: a wing unit; a main body unit; a battery that is arranged in the wing unit; a payload that is arranged in the main body unit; a radiator; and a heat pipe that exchanges heat between the battery, the payload, and the radiator and that has a check valve which causes a hydraulic fluid to be circulated to transfer the heat of the battery to the payload and the radiator.

Claims (51)

1 . A flight vehicle comprising:

a wing unit;

a main body unit;

a battery that is arranged in the wing unit;

a payload that is arranged in the main body unit and that includes at least any of electronic equipment or a control motor;

a radiator; and

a heat pipe that exchanges heat between the battery, the payload, and the radiator and that has a check valve which causes a hydraulic fluid to be circulated to transfer the heat of the battery to the payload and the radiator,

wherein the heat pipe has a battery corresponding portion that corresponds to the battery,

wherein the heat pipe has a radiator corresponding portion that corresponds to the radiator,

wherein the heat pipe has a payload corresponding portion that corresponds to the payload,

wherein the heat pipe has a first circulation portion that extends from the battery corresponding portion, branches at a branch unit, and is connected to each of the radiator corresponding portion and the payload corresponding portion,

wherein the heat pipe has a second circulation portion that extends from the payload corresponding portion and is connected to the radiator corresponding portion, and

wherein the heat pipe has a third circulation portion that extends from the radiator corresponding portion and is connected to the battery corresponding portion.

2 . The flight vehicle according to claim 1 , wherein the check valve is positioned in the third circulation portion.

3 . The flight vehicle according to claim 1 , comprising:

a valve that is arranged between the branch unit and the radiator corresponding portion in the first circulation portion and that is closed when a temperature of the payload is lower than a predetermined temperature threshold value, and is opened when the temperature of the payload is higher than the temperature threshold value.

4 . The flight vehicle according to claim 2 , comprising:

a valve that is arranged between the branch unit and the radiator corresponding portion in the first circulation portion and that is closed when a temperature of the payload is lower than a predetermined temperature threshold value, and is opened when the temperature of the payload is higher than the temperature threshold value.

5 . The flight vehicle according to claim 3 , wherein the valve is a thermostatic valve.

6 . The flight vehicle according to claim 4 , wherein the valve is a thermostatic valve.

7 . The flight vehicle according to claim 3 , comprising:

a valve control unit that controls the valve to close the valve when the temperature of the payload is lower than a predetermined temperature threshold value, and to open the valve when the temperature of the payload is higher than the temperature threshold value.

8 . The flight vehicle according to claim 1 , wherein the payload corresponding portion has a folded shape.

9 . The flight vehicle according to claim 2 , wherein the payload corresponding portion has a folded shape.

10 . The flight vehicle according to claim 3 , wherein the payload corresponding portion has a folded shape.

11 . The flight vehicle according to claim 4 , wherein the payload corresponding portion has a folded shape.

12 . The flight vehicle according to claim 5 , wherein the payload corresponding portion has a folded shape.

13 . The flight vehicle according to claim 1 , comprising:

an air intake unit that is formed at a position corresponding to the battery on a front side of the wing unit;

a heat sink unit that is arranged for the battery and cools the battery by air which flows in from the air intake unit and that includes a ventilation unit having a shape widening from the front side toward a rear side; and

an exhaust unit that is formed at a position corresponding to the battery on the rear side of the wing unit and that exhausts air which flows out from the heat sink unit.

14 . The flight vehicle according to claim 2 , comprising:

an air intake unit that is formed at a position corresponding to the battery on a front side of the wing unit;

a heat sink unit that is arranged for the battery and cools the battery by air which flows in from the air intake unit and that includes a ventilation unit having a shape widening from the front side toward a rear side; and

an exhaust unit that is formed at a position corresponding to the battery on the rear side of the wing unit and that exhausts air which flows out from the heat sink unit.

15 . The flight vehicle according to claim 3 , comprising:

an air intake unit that is formed at a position corresponding to the battery on a front side of the wing unit;

a heat sink unit that is arranged for the battery and cools the battery by air which flows in from the air intake unit and that includes a ventilation unit having a shape widening from the front side toward a rear side; and

an exhaust unit that is formed at a position corresponding to the battery on the rear side of the wing unit and that exhausts air which flows out from the heat sink unit.

16 . The flight vehicle according to claim 4 , comprising:

an air intake unit that is formed at a position corresponding to the battery on a front side of the wing unit;

a heat sink unit that is arranged for the battery and cools the battery by air which flows in from the air intake unit and that includes a ventilation unit having a shape widening from the front side toward a rear side; and

an exhaust unit that is formed at a position corresponding to the battery on the rear side of the wing unit and that exhausts air which flows out from the heat sink unit.

17 . The flight vehicle according to claim 5 , comprising:

an air intake unit that is formed at a position corresponding to the battery on a front side of the wing unit;

a heat sink unit that is arranged for the battery and cools the battery by air which flows in from the air intake unit and that includes a ventilation unit having a shape widening from the front side toward a rear side; and

an exhaust unit that is formed at a position corresponding to the battery on the rear side of the wing unit and that exhausts air which flows out from the heat sink unit.

18 . The flight vehicle according to claim 6 , comprising:

an air intake unit that is formed at a position corresponding to the battery on a front side of the wing unit;

a heat sink unit that is arranged for the battery and cools the battery by air which flows in from the air intake unit and that includes a ventilation unit having a shape widening from the front side toward a rear side; and

an exhaust unit that is formed at a position corresponding to the battery on the rear side of the wing unit and that exhausts air which flows out from the heat sink unit.
