Abstract

The present disclosure relates to a heat radiator and a turbo fracturing unit comprising the same. The heat radiator includes: a cabin; a heat radiation core disposed at the inlet and configured to allow a gas to pass therethrough; a gas guide device disposed at the outlet and configured to suction the air within the cabin to the outlet; and noise reduction core disposed within the cabin, which is of a structure progressively converging to the outlet. The heat radiator is configured to enable the gas to enter the cabin via the inlet, then sequentially pass through the heat radiation core, a surface of the noise reduction core and the gas guide device, and finally be discharged out of the cabin. The heat radiator according to the present disclosure is a suction-type heat radiator which can regulate the speed of the gas guide device based on the temperature of the gas at the inlet, thereby avoiding energy waste and unnecessary noise. The smooth curved surface of the noise reduction core can reduce noise without affecting the gas flow.

First claim

We claim:

a cabin which is provided thereon with an air outlet and an air inlet;
a heat radiation core ( 4 ) disposed at the air inlet allowing air to pass therethrough;
an air displacement device ( 6 ) disposed at the air outlet for suctioning air within the cabin to the air outlet; and
a noise reduction core ( 5 ) disposed within the cabin, the noise reduction core being of a structure progressively converging to the air outlet;
wherein the heat radiator is configured to enable the air to enter the cabin via the air inlet, then sequentially pass through the heat radiation core, flow along a surface of the noise reduction core and the air displacement device, and finally be discharged out of the cabin.

2. The heat radiator according to claim 1 , characterized in that the noise reduction core ( 5 ) comprises:
a core substrate ( 51 ) which is of a hollow tower structure;
a punching outer structure ( 52 ) which is a hollow tower structure opening at a bottom, the punching outer structure being sleeved outside the core substrate; and
a noise reduction material which is filled between the core substrate and the punching outer structure.

3. The heat radiator according to claim 1 , characterized in that the heat radiator is used for cooling a target fluid, wherein the heat radiation core is provided herein with a channel for allowing the target fluid to flow therethrough, and the heat radiation core is configured to enable heat exchange between the air and the target fluid within the channel when the air flows through the heat radiation core.

4. The heat radiator according to claim 3 , characterized in that the heat radiator further comprises:
a temperature sensor ( 16 ) which is disposed at an fluid inlet ( 41 ) of the channel and configured to sense a temperature of the target fluid at the fluid inlet; and
a control device ( 17 ) which is communicatively connected with the temperature sensor ( 16 ) and a motor ( 13 ) for controlling the air displacement device, and configured to control the air displacement device to operate at a speed less than a rated value when the temperature of the target fluid sensed by the temperature sensor is lower than a predetermined value.

5. The heat radiator according to claim 4 , characterized in that the air displacement device ( 6 ) is a fan, and the control device ( 17 ) is configured to control the fan to operate at a rotating speed less than a rated rotating speed when the temperature of the target fluid sensed by the temperature sensor ( 16 ) is lower than a predetermined value.

6. The heat radiator according to claim 4 , characterized in that the predetermined value is pre-stored in the control device ( 17 ) and is set based on the following criteria that: during at least half of a predetermined operation cycle of the heat radiator ( 100 ), the temperature of the target fluid sensed by the temperature sensor ( 16 ) is lower than the predetermined value.

7. The heat radiator according to claim 1 , characterized in that an outer surface of the heat radiation core is provided with a louver protection layer ( 15 ) that comprises a plurality of blades ( 152 ) each having a blade guard panel ( 1522 ), a blade punching panel ( 1521 ), and a blade noise reduction layer ( 1523 ) disposed between the blade guard panel and the blade punching panel.

8. The heat radiator according to claim 1 , characterized in that the cabin at the air outlet is provided with a cabin guard panel ( 2 ) surrounding the air displacement device, the cabin guard panel ( 2 ) comprising a punching panel ( 21 ), an upper guard panel, and a noise reduction material filled between the punching panel and the upper guard panel.

9. The heat radiator according to claim 1 , characterized in that the air inlet is disposed at a side of the cabin, wherein the heat radiation core is disposed at the air inlet, the heat radiation core is formed in a vertical plate structure, and the heat radiation core comprises a plurality of radiation panels connected end to end.

10. The heat radiator according to claim 9 , characterized in that the air outlet is disposed at a top of the cabin.

11. The heat radiator according to claim 1 , characterized in that a surface of the noise reduction core opposite the air inlet is of a recessed shape.

12. The heat radiator according to claim 1 , characterized in that the noise reduction core is of a shape including a pyramid, cone, or truncated cone.

13. The heat radiator according to claim 1 , characterized in that the heat radiator is a cabin heat radiator or barrel heat radiator.
