Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of commercial vehicle diesel engine, in particular to a matrix engine fan. BACKGROUND

[0002] The current commercial vehicle engine adopts a single fan, and its main shortcomings are high energy consumption, high noise and high maintenance cost. In order to meet the cooling needs of the engine, when a single fan is used, a fan with a large enough diameter is needed to suck air from the radiator to enhance the cooling of the radiator, and at the same time, the air blown by the fan covers the entire engine. The large-diameter fan consumes a large output power of the engine, which accounts for 3%-8% of the engine output power under normal working conditions, and up to 10%-15% of the engine output power under high load, directly affecting the vehicle power and fuel economy.

[0003] The large-diameter fan causes significant noise pollution. The tip speed of the large-diameter fan blade is high, which can reach 98 meters per second at the rated speed of the engine. The noise generated by the fan rotating at high speed is one of the main noise sources of commercial vehicles. The noise can reach more than 80 decibels at high load, which is higher than the comfort standard of 65 decibels in the cabin, and long-term driving can easily lead to fatigue.

[0004] The maintenance cost of the single fan is high. The diameter of the single fan is large, so the load of the fan is high, and the driving system of the fan, such as the belt, bearing, tensioner, etc., will be prematurely aged due to the high load of the fan, resulting in high maintenance frequency and cost.

[0005] The industry is constantly optimizing through technical upgrades: for example, using low-drag bionic blades to reduce noise and energy consumption, combining intelligent control (such as electronic silicone oil clutch) to shorten the response delay, or through the whole vehicle thermal management system (such as a flow guide cover, active closed louvers) to improve the heat dissipation efficiency. However, these measures cannot fundamentally solve the above problems.

[0006] Therefore, a solution is needed. SUMMARY

[0043] Scheme analysis:

[0044] 1. Reduce power consumption and improve power economy: four small-diameter fans 35 are used to replace the traditional large-diameter single fan, the small-diameter fan 35 has high blowing efficiency, and the total power consumption is 15%-20% less than that of the single fan under the same cooling demand. Through the linkage of the fan clutch assembly 310 and the engine load, the power consumption is reduced when starting and running at low load, and the engine power is reduced when running at high load, thereby improving the power and fuel economy of the vehicle and solving the high energy consumption problem of the single fan.

[0045] 2. Reduce noise pollution and optimize driving experience: the tip speed of the small-diameter fan 35 is reduced to 51-55 m / s (the tip speed of the traditional single fan is 98 m / s), and the noise caused by the tip cutting air is significantly reduced. At the same time, the matrix layout is matched with intelligent clutch control, and the fan 35 runs at low speed under low load to further reduce noise, thereby solving the problem of driving fatigue caused by high noise of the single fan and improving driving comfort.

[0046] 3. Reduce maintenance cost and prolong component life: the four small fans 35 distribute the load, the driving system (belt, bearing, etc.) is subjected to reduced stress, the aging speed is slowed down, and the maintenance frequency is reduced. The fan support 31 optimizes the structure through the lightening groove and the reinforcing rib, and takes into account the strength and lightweight, thereby reducing the risk of deformation of the support, and solving the problem of high maintenance cost of the single fan driving system which is prone to premature aging from the aspects of structural design and load distribution.

[0047] 4. Intelligent adaptation to working conditions, precise heat dissipation temperature control: The fan clutch assembly 310 intelligently engages / disengages according to the engine heat dissipation demand (coolant temperature), and links four fan 35 variable speeds. Low power consumption ensures continuous cruising at cold start / small load, and strong heat dissipation protects the engine at heavy load, achieving dynamic balance between heat dissipation and energy consumption, breaking through the limitations of traditional technology "optimization but not fundamentally solving", and building a more intelligent and efficient heat dissipation system.

[0048] Technical effects of implementing the present solution:

[0049] The present solution achieves multi-dimensional technical breakthroughs through structural innovation and intelligent control: replacing a single large fan with four small-diameter fans, combined with intelligent clutch adaptation to working conditions, reducing power consumption and improving power and economy; reducing tip speed, reducing noise and optimizing driving experience at low load; dispersing load, optimizing support, and reducing maintenance costs; intelligently dissipating heat on demand, precisely controlling temperature and protecting the engine, fully solving the pain points of single-fan high energy consumption, high noise, and high maintenance costs, and building a more efficient and intelligent heat dissipation system.

[0050] Working principle:

[0051] The matrix fan 35 is installed at the front end of the engine assembly 1. In the working state, the four fans 35 are driven to rotate by the drive belt 316, sucking air from the radiator, strengthening the radiator heat dissipation, and blowing air to the engine assembly 1 to cool the engine.

[0052] The engine accessory belt drive clutch drives the fan clutch assembly 310 to rotate. The fan clutch assembly 310 drives the four fan pulleys 34, which in turn drive the four fans 35 to rotate, sucking air from the radiator and blowing air to the engine to cool it.

[0053] Under different working conditions of the engine, the fan clutch assembly 310 will engage and disengage according to the engine heat dissipation demand, driving the four fans 35 to rotate at different speeds to achieve different degrees of cooling for different loads of the engine.

[0054] When the engine is cold-starting or running at low load, the engine coolant is at a low temperature, and the air blown by the radiator onto the fan clutch assembly 310 is relatively low in temperature. The fan clutch assembly 310 is in a disengaged state, and the fan clutch assembly 310 is idling at a low speed, with a speed of about 10%-30% of the engine speed. At this time, the fan clutch assembly 310 drives the four fans 35 to rotate at a low speed, and the four fans 35 rotate at a low speed, reducing power consumption and noise.

[0055] When the engine cooling liquid temperature is high, the heat of the radiator blows on the fan clutch assembly 310, the high temperature makes the fan clutch assembly 310 engage, so that the fan clutch assembly 310 rotates at a high speed, close to 90% of the engine speed, at this time the fan clutch assembly 310 drives the four fans 35 to rotate at a high speed, the four fans 35 rotate at a high speed, and the heat dissipation effect is enhanced.

[0056] When the engine cooling liquid temperature is low, the heat of the radiator blows on the fan clutch assembly 310, the fan clutch assembly 310 disengages, and the fan clutch assembly 310 rotates at a low speed, at this time the fan clutch assembly 310 drives the four fans 35 to rotate at a low speed, and the fan 35 returns to a low load state.

The present application improves the fan cooling efficiency, reduces the fan power consumption, improves the economy of the whole vehicle, reduces the noise of the fan, and reduces the maintenance frequency and maintenance cost of the fan.
