In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
As shown in fig. 1 and 2, the radiator 4 includes a left water chamber 1 and a right water chamber 2 for storing the cooling liquid. The left water chamber 1 is arranged on the left side of the radiator 4, the right water chamber 2 is arranged on the right side of the radiator 4, and the left water chamber 1 is communicated with the right water chamber 2.
Referring to fig. 1, 3 and 4, the left water chamber 1 provided in this embodiment is provided with a water inlet 9, and the right water chamber 2 is provided with a water outlet 10. The inlet 9 is above the level of the outlet 10. The water inlet 9 is at a higher position to more conveniently inject the cooling liquid into the heat sink 4. The water outlet 10 is at a lower position, so that the cooling liquid can be more conveniently released.
The left water chamber 1 (or the right water chamber 2) is provided with a vent pipe 13, one end of the vent pipe 13 is communicated with the left water chamber 1 (or the right water chamber 2), and the other end of the vent pipe 13 is communicated with the atmosphere. The function of the breather pipe 13 is to discharge the gas (air) of the radiator 4 during operation, while balancing the air pressure of the coolant in the radiator 4, and a hose is connected to the expansion tank 21.
The left water chamber 1 (or the right water chamber 2) is provided with a pressure release valve 14, one end of the pressure release valve 14 is communicated with the left water chamber 1 (or the right water chamber 2), and the other end of the pressure release valve 14 is communicated with the atmosphere. The relief valve 14 is a relief valve of the radiator 4, and functions to relieve pressure when the operating pressure in the radiator 4 is excessive, and may serve as an outlet for discharging the coolant in the radiator 4 at the time of after-sales maintenance.
The radiator 4 further comprises a left fixing column 11 and a right fixing column 12, the left fixing column 11 is arranged on the left side of the radiator 4, the right fixing column 12 is arranged on the right side of the radiator 4, and the left fixing column 11 and the right fixing column 12 are used for being connected with an automobile where the radiator 4 is located. The driving road condition of the automobile is variable, and the bumping degree of the automobile is related to the driving road condition. The left and right water chambers 1 and 2 contain cooling fluid therein, and thus the weight of the radiator 4 itself cannot be ignored. On a bumpy road surface, the inertia of the radiator 4 is larger, and the radiator 4 needs to be firmly fixed through the left fixing column 11 and the right fixing column 12, so that the possibility of damage to the radiator 4 in a bumpy road condition can be reduced. Therefore, the radiator 4 needs to be firmly fixed by the left and right fixing columns 11 and 12 to reduce the possibility of damage to the radiator 4.

As shown in fig. 1 to 4, schematic structural diagrams of different angles of an automotive radiator cleaning apparatus provided in this embodiment are shown.
The embodiment provides a cleaning device including: a water pump 19, a water storage chamber 20 and a water channel 3. The water storage chamber 20 is communicated with the water channel 3, and the water pump 19 is arranged in the water storage chamber 20. Wherein the water pump 19 may be disposed at a middle-lower position within the storage chamber 20 such that the water pump 19 can drive the detergent in the storage chamber 20.
The water storage chamber 20 is used for storing detergent, which may be ordinary clear water, glass water, or other detergent, and the embodiment is not limited thereto.
The capacity of the reservoir 20 may be determined according to the area of the radiator 4. For example, for a radiator 4 with a small area, which needs to be cleaned, the storage chamber 20 with a small capacity can be selected to store a cleaning agent for cleaning the radiator 4; for a radiator 4 with a large area, which needs to be cleaned, the water storage chamber 20 with a large capacity can be selected to store more cleaning agent for cleaning the radiator 4.
The capacity of the reservoir 20 may also be determined according to the severity of the environment in which the vehicle is traveling. For example, in a vehicle traveling in a region with heavy wind and sand, the radiator 4 is more likely to accumulate dirt, and therefore the number of times of cleaning is large, and the water storage chamber 20 with a large capacity can be arranged; in a vehicle running in a region with little wind and sand, the radiator 4 has low dirt accumulation capacity, so that the cleaning frequency is low, and a water storage chamber 20 with low capacity can be configured, so that the vehicle counterweight can be reduced, the vehicle maneuverability is improved, the vehicle energy consumption can be reduced, and the vehicle use cost is reduced. The shape of the water storage chamber 20 can be set according to the vehicle model requirement. The present embodiment does not limit this.
In this embodiment, an injection port 22 is formed at the top of the storage chamber 20 to supply the cleaning agent to the storage chamber 20. In this embodiment, an outlet (i.e., the connection between the waterway and the storage chamber 20) is provided at the bottom of the storage chamber 20, so that the cleaning agent in the storage chamber 20 can flow out of the storage chamber 20 as much as possible. The water storage chamber 20 is higher than the water channel, so that the water channel 3 has certain hydraulic pressure in a natural state, and the load driven by the water pump 19 is reduced.
The water storage chamber 20 is provided with water level indicating lines including a highest water level indicating line and a lowest water level indicating line, and the level where the highest water level indicating line is located is higher than the lowest water level indicating line.
The water channel 3 is arranged on the top of the radiator 4, the water channel 3 is provided with a plurality of nozzles 5, the nozzles 5 correspond to the gaps 7 between the fins 6 on the radiator 4 one by one, and each nozzle 5 faces the corresponding gap 7. One nozzle 5 corresponds to one gap 7.
The water pump 19 is used for driving the cleaning agent in the water storage chamber 20 to flow in the water channel 3, so that the cleaning agent is sprayed out through the nozzle 5 in the process of flowing in the water channel 3, and the gap 7 between two adjacent fins 6 on the radiator 4 is cleaned.
The cleaning agent is sprayed towards the gaps 7 through the nozzles 5 corresponding to the gaps 7, the gaps 7 can be cleaned one to one, and the nozzles 5 are sprayed downwards from the tops of the gaps 7, so that on one hand, stains in the gaps 7 can be washed through the impact force of the cleaning agent sprayed from the nozzles 5, stubborn stains adhered to the fins 6 can be removed, on the other hand, the washed stains can be taken away from the fins 6 through the cleaning agent, the heat radiator 4 is further cleaned, the cleanliness of the heat radiator 4 is improved, and the heat radiation performance of the heat radiator 4 is guaranteed to be in a good state.
The present embodiment provides the following three forms for the waterway 3 including the nozzles 5, specifically including:
[ FORM I ]
As shown in fig. 5, the water passage 3 includes a main pipe 31 and a water spray pipe 32, the nozzles 5 are provided on the water spray pipe 32, and the water spray pipe 32 is provided on the top of the radiator 4. There is only one communication between the main conduit 31 and the water spray conduit 32, and the cleaning solution in the reservoir 20 flows through the main conduit 31 into the water spray conduit 32. The junction of the main pipe 31 and the water spray pipe 32 may be disposed at any position of the water spray pipe 32, and it is shown in fig. 5 that the junction of the main pipe 31 and the water spray pipe 32 is disposed at the end of the water spray pipe 32. Preferably, the connection between the main pipe 31 and the water spraying pipe 32 can be arranged in the middle of the water spraying pipe 32, so that when the detergent flows into the water spraying pipe 32, the hydraulic pressure of the nozzles 5 near the two sides of the connection will be more uniform.
It is to be noted that the schematic structures shown in fig. 1-4 are coordinated with the structure shown in fig. 5.
[ FORM II ]
As shown in fig. 6, the water channel 3 provided with the nozzles 5 includes N groups of water spraying assemblies, each group of water spraying assemblies includes a sub-transmission pipe 33 and a sub-water spraying pipe 34, one end of the sub-transmission pipe 33 is communicated with the water storage chamber 20, the other end of the sub-transmission pipe is communicated with the sub-water spraying pipe 34, the nozzles 5 are provided on the sub-water spraying pipe 34, the sub-water spraying pipe 34 is provided on the top of the radiator 4, and N is a positive integer.
Preferably, the connection position of the sub transport pipe 33 and the sub water spray pipe 34 is located at the middle of the sub water spray pipe 34.
The water channel 3 structure shown in fig. 6 can make the pressure of each nozzle 5 more uniform, and compared with the first form, the pressure of each nozzle 5 is larger, so that the cleaning force of the gap between the fins 6 is also larger, and the cleaning effect is better. And, within a reasonable range, the larger N (or closer to the number of nozzles), the better the cleaning effect on the heat sink 4.
[ FORM III ]
As shown in fig. 7, the water channel 3 provided with the nozzle 5 includes a main pipe 31, a water spraying pipe 32 and M connecting pipes 35, one end of the main pipe 31 is communicated with the water storage chamber 20, one end of each connecting pipe 35 of the M connecting pipes 35 is communicated with the main pipe 31, the other end of each connecting pipe 35 is communicated with the water spraying pipe 32, and a controllable valve is arranged at the connection position of each connecting pipe 35 and the main pipe 31; the water spraying pipe 32 is distributed with nozzles 5 and arranged on the top of the radiator 4, wherein M is a positive integer.
Preferably, the connection positions of the M connection pipes 35 and the water spray pipe 32 are uniformly distributed on the water spray pipe 32. The diameter of the water spraying pipe 32, the diameter of the connection pipe 35, and the diameter of the main pipe 31 increase in order.
The water channel structure shown in fig. 7 is an improvement of the water channel structure shown in fig. 5, the number of joints between the main pipe 31 and the water spraying pipe 32 is increased, a controllable valve is arranged at each joint, and the water pressure at each joint can be adjusted by opening the number of controllable valves, when the number of the controllable valves is increased, the hydraulic pressure at each joint where the controllable valve is opened is relatively lower (it should be noted that the hydraulic pressure at each joint where the controllable valve is not opened has no influence on the pressure in the water spraying pipe 32).
In fig. 7, 4 connecting pipes 35 are provided, and as shown in the figure, the valves are sequentially marked as a first valve, a second valve, a third valve and a fourth valve from top to bottom, when only one of the valves is opened, for example, the second valve is opened, the hydraulic pressure at the connection part corresponding to the second valve is highest, and the water spray pressure of the nozzle 5 near the second valve is the largest, so that the clearance of the corresponding fin 6 is cleaned more cleanly. The farther the distance between the nozzle 5 and the second valve is, the smaller the water spraying pressure is, and the smaller the cleaning force of the gap of the corresponding fin 6 is. And the rest valves are analogized.
Therefore, the cleaning force for different areas of the radiator 4 can be adjusted by controlling the matching of the opening and closing of the valves, and compared with the first form, the cleanliness is higher. And, the larger M (or closer to the number of nozzles), the better the cleaning effect on the heat sink 4.
The controllable valves can be connected with a controller in a subsequent scheme, and the controller controls the opening and closing of each controllable valve, so that the convenience is improved.
On the basis of the above scheme, the present embodiment further provides an optimization scheme:
the cleaning equipment provided by the embodiment further comprises a controller, a front pressure sensor 18, a rear pressure sensor 8 and an air speed sensor, wherein the water pump 19, the front pressure sensor 18, the rear pressure sensor 8 and the air speed sensor are respectively connected with the controller;
the front pressure sensor 18 and the wind speed sensor are arranged on the front side of the radiator 4, and the rear pressure sensor 8 is arranged on the rear side of the radiator 4;
the controller is used for receiving the front pressure data detected by the front pressure sensor 18, the rear pressure data detected by the rear pressure sensor 8 and the wind speed data of the wind speed sensor, determining the degree of dirt on the surface of the radiator 4 according to the front pressure data, the rear pressure data and the wind speed data, and determining whether to control the water pump 19 to drive the cleaning agent in the water storage chamber 20 to flow in the water channel 3 or not according to the degree of dirt.
Specifically, when the automobile is in a running state, the front pressure sensor detects front pressure data, the rear pressure sensor detects rear pressure data, and the front wind speed sensor detects wind speed data. And determining the actual wind resistance of the radiator 4 according to the front pressure data and the rear pressure data, wherein the actual wind resistance is the pressure difference between the front pressure data and the rear pressure data.
And determining the standard wind resistance corresponding to the wind speed data according to the acquired incidence relation between the wind speed and the wind resistance corresponding to the radiator 4. The obtained correlation between the wind speed and the wind resistance corresponding to the heat radiator 4 is as follows: based on the change rule that the wind resistance corresponding to the radiator 4 without dirt exists along with the change of the wind speed. The change rule may exist in a table form or a curve form, which is not limited in this embodiment.
As shown in fig. 8, the correlation between the wind speed and the wind resistance is a curve, and when the wind speed is 4m/s, the corresponding wind resistance is approximately 110Pa, and when the wind speed is 18m/s, the corresponding wind resistance is approximately 2000 Pa.
Based on the correlation between the wind speed and the wind resistance corresponding to the heat sink 4 and the wind speed data, the standard wind resistance corresponding to the wind speed data can be determined.
The degree of soiling of the radiator 4 is determined on the basis of the standard wind resistance and the actual wind resistance.
Specifically, a wind resistance difference is determined based on the standard wind resistance and the actual wind resistance. And if the wind resistance difference is larger than 0 and smaller than or equal to a first preset value, determining that the radiator 4 is not polluted. If the wind resistance difference is greater than the first preset value and less than or equal to the second preset value, it is determined that the degree of contamination of the radiator 4 is light contamination. And if the wind resistance difference is greater than the second preset value and less than or equal to a third preset value, determining that the degree of contamination of the radiator 4 is moderate contamination. And if the wind resistance difference is larger than the third preset value, determining that the degree of the dirt of the radiator 4 is heavy dirt.
And the first preset value is larger than 0, and the first preset value, the second preset value and the third preset value are sequentially increased.
It should be noted that the first preset values corresponding to different wind speed data are different, and similarly, the second preset values corresponding to different wind speed data are different, and the third preset values corresponding to different wind speed data are different. The first preset value, the second preset value and the third preset value can be determined according to the dangq wind speed data and the incidence relation between the wind speed and the wind resistance corresponding to the radiator 4.
When the wind resistance difference is within the range of (0, the first preset value), the radiator 4 is considered to have no contamination, or the current contamination degree of the radiator 4 is considered to have a negligible influence on the radiator performance of the radiator 4.
When the wind resistance difference is within the range of (the first preset value, the second preset value), the degree of soiling of the radiator 4 is considered to be light soiling.
When the wind resistance difference is within the range of (second preset value, third preset value), the degree of contamination of the radiator 4 is considered to be moderate contamination.
When the wind resistance difference is within the range (third preset value, infinity), the degree of contamination of the radiator 4 is considered to be heavily contaminated.
As shown in fig. 9, the curve is a schematic view of curves of wind speed and wind resistance corresponding to different contamination degrees, the curve can be obtained by simulating different degrees of blockage on fins 6 of a heat sink 4 and performing a wind resistance test of a real vehicle at different wind speeds, and can also be obtained by analyzing according to CFD fluid simulation software, which may specifically refer to related technologies, and this embodiment is not described in detail herein.
As can be seen from FIG. 9, when the current wind speed data is 18m/s, the corresponding standard wind resistance is 2000pa (i.e., the data on the curve corresponding to no fouling).
When the wind resistance difference between the actual wind resistance and the standard wind resistance is less than or equal to 500pa (i.e., the difference between 2000pa corresponding to the no-dirty curve and 2500pa corresponding to the light-dirty curve), it is determined that the heat sink 4 is currently in the no-dirty state, and no processing may be performed.
When the wind resistance difference between the actual wind resistance and the standard wind resistance is greater than 500pa (i.e., the difference between 2000pa corresponding to the no-dirty curve and 2500pa corresponding to the light-dirty curve), and is less than or equal to 900pa (i.e., the difference between 2000pa corresponding to the no-dirty curve and 2900pa corresponding to the medium-dirty curve), the heat sink 4 is considered to be in the light-dirty state.
When the wind resistance difference between the actual wind resistance and the standard wind resistance is greater than 900pa (i.e., the difference between 2000pa corresponding to the no-dirty curve and 2900pa corresponding to the moderate-dirty curve), and is less than or equal to 1300pa (i.e., the difference between 2000pa corresponding to the no-dirty curve and 3300pa corresponding to the severe-dirty curve), the heat sink 4 is considered to be in the moderate-dirty state.
