And a plurality of air guiding units 3 disposed at the outer cover body 2, wherein the outer cover body 2 has a T shape, and the outer cover body 2 includes a space region 20 provided with a hollow closed shape, and a communication body The air inlet 20 is located at the air inlet port 21 at the outer side of the outer cover body 2, and the air inlet port 21 is assembled and fitted at the heat sink or the air outlet pipe or the roof to serve as internal hot air through the heat sink or the air outlet pipe. And directly flowing into the closed space region 20; the air guiding unit 3 includes at least a guiding channel 30 extending transversely to the closed space region 20 of the outer cover 2, and disposed on the guiding channel 30 to The air intake and exhaust port 31 between the closed space region 20, the drainage channel 32 that protrudes from the outer side of the outer cover body 2 and communicates with the guiding channel 30, and the protruding channel 30 are protruded from the guiding channel 30. And the guiding piece 33 at the drainage channel 32, and the position of the contact surface between the air guiding unit 3 and the outer cover 2 The outer side of the outer cover body 2 is protruded and protruded from the outer side of the outer cover body 2, and the maximum end face diameter of the air guiding unit 3 that protrudes outside the outer cover body 2 is a diameter larger than a contact surface formed at a contact position between the outer cover 2 and the air guiding unit 3 (ie, a cone In addition, the air intake and exhaust port 31 must be disposed in the space region 20 of the outer cover body 2, and cannot be disposed at a position below the center horizontal line of the guide channel 30, and protruded from the outer cover. A drainage channel 32 is formed at the air guiding unit 3 outside the body 2, and the drainage channel 32 is connected to the guiding channel 30. Further, the guiding channel 30 and the drainage channel 31 are formed with a protrusion. The guiding piece 33 is used to guide the flow of the airflow; and the air guiding unit 3 is at least one or more tubular bodies, or at least one open tubular body having a curved cross section, or For at least one of the sheets; when the sunlight is directly incident on the roof 5, the exhaust port 50 of the roof 5 is connected to the air inlet 21 of the outer cover 2, so that the interior and the The closed space region 20 of the outer cover body 2 is in communication with each other such that the internal hot air inside the house can be lifted up and flowed into the closed space region 20 of the outer cover body 2, at this time, since the outer cover body 2 The space area 20 is directly connected to the guide by the setting action of the air intake and exhaust port 31 At the guiding passage 30 of the unit 3, the rising internal hot air can be directly flowed into the guiding passage 30; at this time, the external cold air flows through the drainage passage 32 due to the drainage passage 32. The diameter of the outer end surface is larger than the diameter of the contact surface, in other words, the maximum end surface diameter of the air guiding unit 3 that protrudes outside the outer cover 2 is larger than the outer cover 2 and the air guiding unit 3 The diameter of the contact surface formed at the contact position is such that the flow rate to the drain channel 32 is less than the flow rate to the guide channel 30 (since the cross-sectional diameter of the guide channel 30 is smaller than the drain channel 32) In addition, the guiding piece 33 extends from the drainage channel 32 to the guiding channel 30 to form a direction protruding in the axial direction, thereby causing the guiding piece 33 to flow through the guiding piece 33. The flow rate between the guiding passages 30 is greater than the flow rate of the internal hot air flowing into the guiding passages 30, in addition to being able to directly flow into the guiding The internal hot air in the passage 30 flows outside the other side, and at the same time, the external cold air flowing through the guide passage 30 is quickly passed through the surface of the air suction exhaust port 31, thereby causing the external The cold air can generate a suction or traction effect after the flow at the suction and exhaust port 31 to accelerate the internal hot air that has been sucked in the intake and exhaust port 31 and mixed into the external cold air in the guide passage 30.
