Detailed Description
Example one
An embodiment of the present invention provides a method for controlling a heat sink flow, as shown in fig. 1, the method includes:
Each heat source system comprises an environment-controlled liquid cooling system, a hydraulic system and an engine lubricating oil system. The acquisition mode is as follows: and collecting temperature values of each system through temperature sensors of each heat source system, and sending the temperature values to a computer for judgment.
And 102, when the temperature of the target heat source system in each heat source system is not in the target preset range of the target heat source system, adjusting the heat dissipation flow until the temperature of each heat source system is in the corresponding preset range.
And when the temperature of the target heat source system in each heat source system is within the target preset range of the target heat source system, the heat dissipation flow is kept unchanged.
Further, step 102 specifically includes:
and 1021, increasing a first preset amount for the heat dissipation flow when the temperature of the target heat source system is greater than the upper limit of the target preset range.
The method of increasing the first predetermined amount for the heat dissipation flow may be adjusted by controlling a flow regulating valve.
When any one of the temperatures of the environment-controlled liquid cooling temperature, the hydraulic temperature and the generator lubricating oil temperature exceeds the upper temperature limit, the flow regulating valve is increased by an opening value, for example, the opening is increased by 10 degrees. Here, the opening degree value is the first preset amount in the present embodiment.
And 1022, when the temperature of the target heat source system is smaller than the lower limit of the target preset range, reducing a second preset amount for the heat dissipation flow.
When the temperatures of the environment-controlled liquid cooling temperature, the hydraulic temperature and the generator lubricating oil temperature are lower than the lower temperature limit, the flow regulating valve is reduced by an opening value. For example, the opening degree is decreased by 5 degrees. Here, the opening value is the second preset amount in the present embodiment.
The first predetermined amount and the second predetermined amount may be the same or different.
Further, step 101 specifically includes:
and step 1011, obtaining the end time of the last adjustment of the heat dissipation flow.
And recording the end time of the last adjustment of the heat dissipation flow.
And 1012, acquiring the temperature of each heat source system when the time length from the ending time to the current time is greater than or equal to the preset time length.
And starting timing from the last time when the heat dissipation flow is adjusted, and judging the temperature of each heat source system when the preset time is reached. For example, timing is started after the last adjustment of the heat dissipation flow is finished, the temperature of each heat source system is judged again after the time reaches 5s, and how to control the flow regulating valve is decided according to the judgment result.
Further, the method further comprises:
and 103, detecting whether an acceleration instruction is received.
For example, the acceleration command is a boost signal, and it is detected whether the boost signal is received.
And 104, increasing the heat dissipation flow to the maximum value when an acceleration instruction is received.
For example, when the force application signal is detected, the opening degree of the flow rate adjustment valve is adjusted to the maximum. Here, the magnitude of the heat dissipation flow rate is determined by the opening degree of the flow regulating valve, and the larger the opening degree of the flow regulating valve is, the larger the heat dissipation flow rate is; the smaller the opening of the flow rate adjusting valve is, the smaller the heat radiation flow rate is.
Further, after step 104, the method further comprises:
and 105, acquiring the temperature of each heat source system when receiving the acceleration canceling instruction.
For example, when the cancellation of the energization signal is detected, the opening degree of each heat source system temperature adjustment flow rate adjustment valve is determined.
The embodiment realizes real-time and fine control of the heat dissipation flow, controls the temperature of each heat source system within a reasonable range, meets the heat dissipation requirements of each system, and improves the oil consumption and heat dissipation capacity of the engine.
Example two
The embodiment of the invention provides a heat sink flow control method, which is applied to a fuel oil heat management system and comprises the following steps:
And step 204, acquiring the temperature of each heat source system when an acceleration canceling instruction is received.
And step 206, when the temperature of the target heat source system is smaller than the lower limit of the target preset range, reducing a second preset amount for the heat dissipation flow.
The advantages are that: when the engine consumes oil greatly, the flow of the heat dissipation path is controlled to be maximum, so that the engine consumes oil to take away more heat as far as possible, and the heat load of the airplane is reduced.
The technical scheme is as follows: the principle of the scheme is shown in figure 3, and after being pressurized by a fuel pump, the fuel heat sink sequentially flows through the environment-controlled liquid cooling radiator, the hydraulic radiator and the generator lubricating oil radiator and then returns to the fuel supply pipe to be consumed by the engine. A flow regulating valve is arranged on a pipeline at the outlet of the generator lubricating oil radiator, and the opening of the flow regulating valve is controlled in real time to control the heat dissipation flow through the environment-controlled liquid cooling temperature, the hydraulic temperature and the generator lubricating oil temperature which are acquired in real time. On the premise of meeting the heat dissipation flow requirements of an environment control system, a hydraulic system and a generator system, the heat sink flow of a heat dissipation path is reduced as much as possible, so that the heat dissipation flow is in an optimized and reasonable range, and the temperature of fuel at the inlet of an engine is increased. The specific control mode is as follows:
when any one of the temperature of the environment-controlled liquid cooling temperature or the hydraulic temperature or the temperature of the lubricating oil of the generator exceeds the upper temperature limit, the flow regulating valve is increased by an opening value;
when the temperatures of the environment-controlled liquid cooling temperature, the hydraulic temperature and the generator lubricating oil temperature are lower than the lower temperature limits, the flow regulating valve is reduced by an opening value;
when the temperature of the environment-controlled liquid cooling temperature, the hydraulic temperature and the temperature of the lubricating oil of the generator are all between the upper temperature limit and the lower temperature limit, the opening of the flow regulating valve is kept unchanged.
