As shown in fig. 1, the present embodiment provides an excavator cooling system, which is designed to solve the problem that an existing water cooling system is not easy to meet the cooling requirement of equipment due to a large power and a large heat generation amount of an excavator, and to solve the problem that the heat dissipation effect is affected and the cooling requirement of the equipment is not easily met due to a complex working environment of the excavator and that substances such as dust in a working place block the radiator 1; therefore, the present embodiment is improved based on the existing excavator water cooling system, and the water storage tank 2 is added to assist in heat dissipation of the heat sink 1.
Specifically, the excavator cooling system of the present embodiment includes a radiator 1, a water storage tank 2, a first pipeline 3, a second pipeline 4, a first temperature detection component 5 and a controller 6; the radiator 1 of the present embodiment is an existing excavator water-cooled radiator 1, and therefore, the present embodiment will not be described in detail with respect to a specific operation process and a structural form thereof. The water storage tank 2 of the present embodiment is a tank structure capable of accommodating a water body, and the size of the tank structure is not much smaller than that of the radiator 1 as shown in the figure, and the specific structural size is designed accordingly according to the heat dissipation requirement.
The first pipeline 3 and the second pipeline 4 of the present embodiment are both of water pipe structures, the first temperature detection component 5 and the second temperature detection component 7 described below of the present embodiment may be temperature sensors, etc., and the controller 6 of the present embodiment may be any controller 6 capable of receiving data, processing data, and sending control instructions, such as a PLC, etc., so the present embodiment does not describe the structures and the operation principles of the components such as the controller 6 and the temperature detection components.
In order to realize the communication between the radiator 1 and the water storage tank 2, the radiator 1 of the embodiment is provided with a first water inlet 8 and a first water outlet 9, correspondingly, the water storage tank 2 of the embodiment is provided with a second water inlet 10 and a second water outlet 11, one end of the first pipeline 3 of the embodiment is connected with the first water outlet 9, and the other end of the first pipeline is connected with the second water inlet 10; one end of the second pipeline 4 of this embodiment is connected to the second water outlet 11, and the other end is connected to the first water inlet 8. In addition, the first pipeline 3 of the present embodiment is connected with a first water distributor 12 capable of guiding the water in the radiator 1 into the water storage tank 2; the second pipeline 4 is provided with a second water distributor 13 which can guide the water in the water storage tank 2 into the radiator 1. The first temperature detection component 5 of the present embodiment is used for detecting the temperature of the heat sink 1, specifically, detecting the temperature of the outer surface of the heat sink 1, and the temperature of the outer surface of the heat sink 1 can more visually display the overall temperature of the heat sink 1.
The controller 6 of the present embodiment is respectively connected to the first temperature detecting component 5, the first water distributor 12 and the second water distributor 13, and the connection manner may be a line connection or a wireless signal connection; the temperature detection means of the present embodiment detects the temperature of the heat sink 1 in real time and transmits the temperature data to the controller 6, the controller 6 makes a comparison determination, when it is judged that the temperature of the heat sink 1 detected by the first temperature detecting part 5 reaches the first preset value, the controller 6 of this embodiment opens the first water distributor 12 and the second water distributor 13, introduces the water in the radiator 1 into the water storage tank 2 through the first water outlet 9, the first pipeline 3 and the second water inlet 10 in sequence, and the water in the water storage tank 2 is led into the radiator 1 through the second water outlet 11, the second pipeline 4 and the first water inlet 8 in turn, so that the water body with lower temperature in the water storage tank 2 and the water body with higher temperature in the radiator 1 complete heat exchange, and then reduce the water temperature in radiator 1 to reduce radiator 1 overall temperature, ensure that radiator 1 is in good heat dissipation state.
Above-mentioned structure has newly increased storage water tank 2 as auxiliary cooling device in cooling system, and when water temperature was too high in radiator 1, can lower the temperature to radiator 1 through the water of storage in the storage water tank 2, ensures that the excavator temperature is in reasonable temperature state, avoids the high temperature and influences its radiating effect, has guaranteed the reliable operation of radiating working part of needs.
Based on the above structure, the inventor finds that, after the first water distributor 12 and the second water distributor 13 are opened, the radiator 1 and the water storage tank 2 are always in a water circulation state, so that the water in the water storage tank 2 cannot be reduced to be consistent with the outside temperature, and the radiator 1 cannot be cooled in the next heat dissipation process, and it is very inconvenient to manually close the first water distributor 12 and the second water distributor 13, because it is not known whether the water storage tank 2 sufficiently cools the radiator 1, therefore, in order to achieve the automatic closing of the first water distributor 12 and the second water distributor 13, the excavator heat dissipation system of this embodiment further includes a second temperature detection part 7, the second temperature detection part 7 of this embodiment is connected with the controller 6, and the connection mode may be wireless connection or line connection.
Specifically, the second temperature detecting component 7 of this embodiment is installed in the water storage tank 2 and is used for detecting the temperature of the water in the water storage tank 2 in real time, and then transmits the temperature data to the controller 6, and the controller 6 performs comparison and judgment, and when it is judged that the temperature of the water in the water storage tank 2 detected by the second temperature detecting component 7 reaches the second preset value, the controller 6 of this embodiment closes the first water distributor 12 and the second water distributor 13, and cuts off the communication between the water storage tank 2 and the radiator 1.
In order to simplify the structure and reduce the installation space, the first water distributor 12 and the second water distributor 13 of the present embodiment do not use a water pump or the like, but use an electromagnetic control valve having a water pumping function to introduce and discharge water.
In addition, the excavator cooling system of this embodiment may further include an alarm prompting device (not shown in the figure), the alarm prompting device is connected to the controller 6, when the temperature of the water in the water storage tank 2 reaches a third preset value, the controller 6 turns on the alarm prompting device, the third preset value is greater than the first preset value and the second preset value, and when the third preset value is reached, it is described that the temperature of the radiator 1 is already high, and the working part of the equipment is easily damaged, so that the alarm prompting device reminds the operator, and the operator may turn off the excavator, and replace the water in the water storage tank 2 and the radiator 1, so as to achieve the purpose of cooling.
In addition, the present embodiment also provides an excavator, which has the excavator heat dissipation system according to the above technical solution, and since the excavator of the present embodiment is improved only by the heat dissipation system, other structures of the excavator are not illustrated in the present embodiment.
With reference to fig. 1 and 2, based on the excavator cooling system, the present embodiment further provides a cooling method using the excavator cooling system, which specifically includes the following steps:
acquiring temperature data of the radiator 1 of the excavator, and judging whether the temperature data reaches a first preset value;
when the temperature data reaches a first preset value, the water in the radiator 1 is guided into the water storage tank 2, and the water in the water storage tank 2 is guided into the radiator 1.
Specifically, the data acquisition process is to monitor the temperature of the outer surface of the heat sink 1 in real time through the first temperature detection component 5, and transmit the temperature data to the controller 6. The judgment process is to preset a first preset in the controller 6 and judge whether the temperature data reaches the first preset value through a comparison module in the controller 6.
In addition, in order to realize the automatic closing of the first water distributor 12 and the second water distributor 13, the heat dissipation method further includes acquiring the temperature of the water body in the water storage tank 2 through the second temperature detection component 7, and when the temperature of the water body in the water storage tank 2 reaches a second preset value, the controller 6 closes the conduction between the heat radiator 1 and the water storage tank 2.
Preferably, in the heat dissipation method, the first preset value is smaller than the second preset value, because the temperature of the outer surface of the heat sink 1 is generally lower than the temperature of the water in the heat sink 1, if the first preset value is greater than or equal to the second preset value, it indicates that the temperature of the water in the heat sink 1 is definitely greater than the temperature of the water in the water storage tank 2, that is, the two are not sufficiently heat-exchanged, therefore, in order to make the water in the two sufficiently exchange heat, the first preset value is designed to be smaller than the second preset value in the present embodiment, and a specific difference between the first preset value and the second preset value is determined according to the corresponding difference between the inside and.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
