Description

Technical Field

[0001] The present invention relates to the technical field of internal combustion engine heat dissipation, and specifically to a control system and method for balanced operation of multiple fans of a horizontal radiator of an internal combustion engine. Background Art

[0002] When a land-based internal combustion engine operates, the cooling water temperature is mainly dissipated in the form of a cooling water tower or a horizontal radiator. At present, with the development of mobile internal combustion engine power stations, higher requirements are put forward for the independence, integrity, flexibility, and mobility of mobile internal combustion engine power stations. Therefore, a horizontal radiator with a compact structure and flexible installation has become the main equipment for cooling the cooling water of mobile internal combustion engine power stations.

[0003] The horizontal radiator is equipped with multiple groups of cooling fans. If the control logic of multiple groups of fans is unclear and unreasonable, it is extremely easy to cause unbalanced operation of the fans, that is, some fans have a short operation time and low utilization rate, while some fans have an overly long operation time and high utilization rate, resulting in overloading and overcurrent of the fans, thereby reducing the service life of the fans and affecting the reliable operation of the mobile internal combustion engine power station. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects, and provide a control system and method for balanced operation of multiple fans of a horizontal radiator of an internal combustion engine, which can balance the operation utilization rate of multiple groups of fans, avoid the problem of large losses of some fans and small losses of some fans, and overall improve the heat dissipation performance of the horizontal radiator, and can effectively solve the problems in the background art.

When the priority value is equal to the number of groups of radiator fans, the priority value automatically resets to zero;

[0014] The cooling water temperature is divided into five threshold intervals. When the logic control part detects that the cooling water temperature transmitted by the water temperature detection part reaches the first threshold value, start a group of radiator fans and simultaneously judge the value of the priority;

[0043] Compared with the prior art, the beneficial effects of the present invention are as follows: The control system and method for balanced operation of multiple fans of the horizontal radiator of the internal combustion engine compares the outlet cooling water temperature during the operation of the internal combustion engine with the defined temperature threshold value. For different temperature threshold intervals where the outlet water temperature is located, the fan group with the corresponding priority is selected to operate, so as to evenly control the operation time of the cooling fans in the horizontal radiator of the internal combustion engine, thereby maximizing the utilization rate of the cooling fans, increasing the service life of the cooling fans, and ensuring the reliable operation of the mobile internal combustion power station.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0049] Such as Figure 1 , A control system for balanced operation of multiple fans of a horizontal radiator of an internal combustion engine, including a water temperature detection part 17, a logic control part 16, and a network terminal part 18;

[0050] The water temperature detection part includes a sampling component and a temperature monitoring element. The sampling component is installed on the straight pipe section between the outlet of the internal combustion engine and the inlet of the horizontal radiator, and the temperature monitoring element is installed inside the sampling component;

[0051] Specifically, the source component is installed within the range of 0 to 45° with the horizontal center line of the straight pipeline in the lower half of the straight pipeline, and is installed against the cooling water flow direction. The axis of the source component should intersect with the axis of the straight pipeline. The temperature monitoring element detects the temperature of the cooling water out of the engine in real time during the operation of the internal combustion engine, and transmits the real-time detection value to the logic control part 16;

[0052] Based on the change data of the real-time temperature of the cooling water out of the internal combustion engine transmitted by the water temperature detection part 17, the logic control part 16 performs grouped, graded, and balanced control on the horizontal radiator cooling fans of the internal combustion engine. At the same time, it communicates the temperature of the cooling water out of the internal combustion engine and the stop, operation, and fault status of each cooling fan of the horizontal radiator to the network terminal part 18 in real time. The network terminal part 18 transmits the temperature of the cooling water out of the internal combustion engine and the stop, operation, and fault status of each cooling fan of the horizontal radiator to the mobile phone of the remote staff.

[0053] Among them, the network terminal part 18 is a WIFI gateway used to connect the lower-level devices of the EMCP Internet of Things cloud platform. It uses the WIFI network to automatically collect and transmit Modbus data, and transmits data status such as the temperature of the cooling water out of the internal combustion engine and the stop, operation, and fault status of each cooling fan of the horizontal radiator to the mobile phone of the remote staff.

[0054] Such as Figure 2 the present invention also provides a control method for the balanced operation of multiple fans of the horizontal radiator of the internal combustion engine. The logic control part 16 divides ten cooling fans into five groups, with two in each group for control;

[0055] The initial value of the priority level involved in the logic control part 16 is zero. The logic control part 16 takes the timing period T of the time element as one timing period. When the timing reaches the timing period T of the time element, the time element automatically resets to zero and starts timing again, and the priority level automatically increases by 1. When the priority level value is equal to the number of fan groups n, that is, the value is 5, the priority level value automatically resets to zero;

[0061] When the priority is 4, start the fifth group of cooling fans 5 to run, that is, the 9# cooling fan 14 and the 10# cooling fan 15 start to run.

[0062] When the cooling water temperature reaches the second water temperature threshold value T2 but is less than the third water temperature threshold value T3, enter the control logic F101, start two groups of fans, and at the same time judge the value of the priority:

[0063] When the priority is 0, start the first group of cooling fans 1 and the second group of cooling fans 2 to run, that is, the 1# cooling fan 6, the 2# cooling fan 7, the 3# cooling fan 8, and the 4# cooling fan 9 run;

[0064] When the priority is 1, start the second group of cooling fans 2 and the third group of cooling fans 3 to run, that is, the 3# cooling fan 8, the 4# cooling fan 9, the 5# cooling fan 10, and the 6# cooling fan 11 run;

[0068] When the cooling water temperature reaches the third water temperature threshold value T3 but is less than the fourth water temperature threshold value T4, enter the control logic F102, start three groups of fans, and at the same time judge the value of the priority:

[0069] When the priority is 0, start the first group of cooling fans 1, the second group of cooling fans 2, and the third group of cooling fans 3 to run, that is, the 1# cooling fan 6, the 2# cooling fan 7, the 3# cooling fan 8, the 4# cooling fan 9, the 5# cooling fan 10, and the 6# cooling fan 11 run;
