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/air to pass therethrough; a gas/air guide device disposed at the outlet and configured to suction the air within the cabin to the outlet; and noise reduction structure disposed within the cabin, which is of a structure progressively converging to the outlet. The heat radiator is configured to enable the gas/air to enter the cabin via the inlet, then sequentially pass through the heat radiation core, a surface of the noise reduction structure and the gas/air 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/air guide device based on the temperature of the gas/air at the inlet, thereby avoiding energy waste and unnecessary noise. The smooth curved surface of the noise reduction structure can reduce noise without affecting the gas/air flow.

First claim

We claim:

1. A heat radiator, characterized in that the heat radiator comprises:
a cabin comprising an air outlet and an air inlet;
a heat radiation core disposed at the air inlet with coolant therein;
an air suction device disposed at the air outlet;
a temperature sensor disposed within the coolant for measure a temperature of the coolant;
a noise reduction structure disposed within the cabin and being progressively converging to the air outlet from a base of the cabin; and
a controller for adaptively adjust an amount of an air flow from outside of the air inlet, through the cabin, to the air outlet.

2. The heat radiator according to claim 1 , wherein the noise reduction structure comprises:
a core substrate having a hollow tower structure;
a punctured outer structure in a form of a hollow tower structure opening at the base, the punctured outer structure being sleeved outside the core substrate; and
a noise absorption material filled between the core substrate and the punctured outer structure.

3. The heat radiator according to claim 1 , wherein a surface of the noise reduction structure facing the air inlet is of a recessed shape.

4. The heat radiator according to claim 1 , wherein the noise reduction structure is shaped in a pyramid, a cone, or a truncated cone converting to the air outlet.

5. The heat radiator according to claim 1 , wherein the heat radiation core is provided with a channel for confining the coolant to cool the air flow via a heat exchange.

6. The heat radiator according to claim 5 , wherein the channel of the heat radiation core comprises a coolant inlet and a coolant outlet for circulating the coolant through the channel.

7. The heat radiator according to claim 5 , wherein the coolant comprises water or oil.

8. The heat radiator according to claim 1 , wherein the air suction device comprises a suction fan driven by a motor.

9. The heat radiator according to claim 8 , wherein the controller is configured to adjust the amount of the air flow by controlling a rotational speed of the motor according to a comparison of the measured temperature of the coolant with a temperature threshold.

10. The heat radiator according to claim 9 , wherein the controller is configured to turn off the motor when the measured temperature is below the temperature threshold.

11. The heat radiator according to claim 9 , wherein the controller is configured to control the rotational speed of the motor to be less than a rated value when the measured temperature is lower than the temperature threshold.

12. The heat radiator according to claim 9 , wherein the temperature threshold is determined at a value such that during at least half of a predetermined operation cycle of the heat radiator, the measured temperature is lower than the temperature threshold.

13. The heat radiator according to claim 1 , wherein an outer surface of the heat radiation core is provided with a louver protection layer comprising a plurality of blades each having a blade guard panel, a punctured blade panel, and a noise reduction layer disposed between the blade guard panel and the punctured blade panel.

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

15. The heat radiator according to claim 14 , wherein the air outlet is disposed at a top of the cabin.

16. The heat radiator according to claim 1 , wherein the heat radiator comprises a cabin heat radiator or a barrel heat radiator.

17. The heat radiator according to claim 1 , wherein the cabin comprises a coverable manhole for maintenance.

18. The heat radiator according to claim 17 , wherein the cabin further comprises a ladder below the coverable manhole.

19. The heat radiator according to claim 1 , wherein the cabin is disposed adjacent a turbine engine to draw circulating air around the turbine engine.
