Description

Technical Field

[0001] The invention relates to the technical field of engine cooling wire harnesses, and in particular to a forced cooling wire harness structure. Background Art

[0002] A large number of sensors and actuators need to be arranged on modern engines, and the wiring harness is connected to the sensor or actuator through a connector; the connectors used to connect these sensors and actuators to the wiring harness are all injection molded parts, and the ambient temperature they can withstand is limited. As a thermal engine, there are a large number of high-temperature parts on the engine, so it is inevitable that some sensors and actuators will be affected by high temperatures. When the temperature is higher than the allowable temperature of the connector, wire, and wire protective layer, it will cause damage to the parts. At present, the wire harness is generally improved by improving the wire and protective layer to improve the temperature resistance level, but it is not enough to just be heat resistant. In order to ensure the stable reception of sensor and actuator signals and to ensure that the connectors of the sensor and actuator do not fail due to high temperature, it is necessary to cool down. Although there is currently a water cooling method for cooling the wiring harness, the actual use effect is not good, and it is easy to leak and short circuit during use. Serious faults, such as, therefore, the current market will not consider the use of water cooling, and the use of air cooling is undoubtedly the most market-potential solution, but there are still many technical problems with the use of air cooling, mainly the cooling efficiency ratio and energy consumption, and the low cooling efficiency of the wire inside the insulator. So far, there is no effective means to improve it.

Summary of the invention

[0004] In view of the above technical problems, the present invention provides a forced cooling harness structure with good cooling effect.

[0005] To achieve the above object, the present invention adopts the following technical solution:

[0006] A forced cooling harness structure comprises a ventilation and heat dissipation pipe, an air joint and an enhanced cooling flap; the air joint is connected to an air intake pipe on the upper side of its main pipe body, and its front end is connected to one end of the ventilation and heat dissipation pipe; the enhanced cooling flap is nearly funnel-shaped, and the inner cavity of the pipe body in the middle thereof is provided with a plurality of axially distributed tooth convex strips; the outer edge of the enhanced cooling flap is tightly combined with the inner cavity of the ventilation and heat dissipation pipe; the inner cavity of the ventilation and heat dissipation pipe is distributed with a plurality of the enhanced cooling flaps; the harness to be cooled is distributed through the inner cavity of the pipe body in the middle of the enhanced cooling flap.

[0007] Furthermore, the enhanced cooling flaps are reversely connected in pairs to form an enhanced cooling flap assembly in a nearly "X" shape, and a plurality of the enhanced cooling flap assemblies are distributed alternately, and a circulating cooling cavity is formed between two adjacent enhanced cooling flap assemblies.

[0008] Furthermore, a circle of heat dissipation holes is provided on the tube wall of the ventilation and heat dissipation tube corresponding to the middle part of the enhanced cooling flap assembly.

[0009] Furthermore, it also includes a cooling protection sleeve head, which is set at the connection between the wiring harness and the sensor / actuator and is connected to the other end of the ventilation and heat dissipation pipe; the sensor / actuator end of the cooling protection sleeve head is provided with a plurality of air outlet holes, and the air outlet holes are in close contact with the outer surface of the sensor / actuator.

[0010] Furthermore, the enhanced cooling flap is made of silicone material.

[0011] Furthermore, the plurality of enhanced cooling flap assemblies are spaced 0.5 cm, 1 cm, 1.5 cm, 1.8 cm, 2.0 cm or 2.5 cm apart from each other.

[0015] The beneficial effects of the present invention compared with the prior art are as follows:

[0016] (1) The present invention provides a ventilation heat dissipation pipe, an air joint, and a cooling protection cover, so that the wiring harness is first air-cooled, and then the cooling air is ejected from the air outlet to perform jet cooling on the sensor / actuator, etc., thereby significantly reducing the temperature.

[0017] (2) The present invention provides a plurality of enhanced cooling flap assemblies in the ventilation and heat dissipation pipe to form a circulating cooling chamber. The cooling air enters the ventilation and heat dissipation pipe from the bell mouth of the enhanced cooling flap and then sprays to the other side from the gap between the teeth and ridges of the small-diameter opening of the enhanced cooling flap. At this time, the airflow is enhanced and directly sprayed onto the outer surface of the wiring harness for forced cooling with good cooling effect. At the same time, the airflow continues to enter the circulating cooling chamber and circulates. In the circulating flow process, the wiring harness is fully heat-conducted to quickly reduce the heat of the wiring harness body, improve the effective heat transfer utilization rate of the cooling air, and reduce energy consumption. Then, the cooling air is sprayed to the other side from the gap between the teeth and ridges of the small-diameter opening of the next enhanced cooling flap, and the flow is conducted step by step, which significantly improves the heat transfer efficiency and the rapid and efficient cooling effect. At the same time, the heat dissipation holes and heat dissipation bosses provided on the pipe wall of the ventilation and heat dissipation pipe can improve the heat dissipation effect of the enhanced cooling flap.

[0018] (3) The non-return membrane provided on the air joint can effectively seal the wiring harness and prevent the cooling air flow from leaking from this place.

[0019] (4) The air inlet pipe of the air connector adopts a bamboo joint structure to improve the stability of connecting the high-pressure air pipe. BRIEF DESCRIPTION OF THE DRAWINGS

The outer edge of the enhanced cooling flap 7 is tightly combined with the inner cavity of the ventilation and heat dissipation pipe 1 to prevent air leakage; the enhanced cooling flaps 7 of this embodiment are reversely docked in pairs to form an enhanced cooling flap assembly that is nearly "X" shaped, and a plurality of the enhanced cooling flap assemblies are arranged at intervals of 0.5 cm, 1 cm, 1.5 cm, 1.8 cm, 2.0 cm, or 2.5 cm. A circulating cooling cavity 8 is formed between two adjacent enhanced cooling flap assemblies.
