A cooling device

Abstract

This invention discloses a cooling device, including a chassis, a heat dissipation structure, and a cooling fan structure. By integrating the heat dissipation structure and the cooling fan structure within the chassis, the installation space requirement is significantly reduced, and daily maintenance and overall replacement are facilitated. The heat dissipation structure provides power for the circulation of cooling medium through a pump, achieving the purpose of cooling the first structure to be cooled (e.g., a converter). The cooling fan structure uses a dual-output shaft drive to simultaneously drive two sets of impeller assemblies, drawing ambient air sequentially through side wall openings, the radiator, and the air inlet duct into the impeller assembly. During this process, the radiator exchanges heat with the ambient air to achieve its own cooling. The air after heat exchange continues to be blown towards the second structure to be cooled (e.g., a traction motor) through the exhaust duct. This achieves cooling of both the first and second structures to be cooled, with low energy consumption and high reliability.

[0015] The application of the technical solution of the present invention has the following beneficial effects:

[0016] (1) The cooling device of the present invention includes a chassis, a heat dissipation structure and a cooling fan structure. In the present invention, by integrating the heat dissipation structure and the cooling fan structure into the chassis, the installation space requirement can be greatly reduced, and daily maintenance and overall replacement can be facilitated. The heat dissipation structure provides the power for the circulation of cooling medium through a pump, so that the cooling medium circulates in the circulating cooling loop to achieve the purpose of cooling the first structure to be cooled (e.g., a converter). The cooling fan structure uses a dual-output shaft drive to simultaneously drive two sets of impeller assemblies to draw the ambient air into the impeller assembly through the side wall opening, the radiator and the air inlet. During this process, the radiator exchanges heat with the ambient air to achieve the cooling of the radiator itself. The air after heat exchange continues to be blown to the second structure to be cooled (e.g., a traction motor) through the exhaust duct. The cooling device of the present invention uses a set of drive components to achieve the cooling of the first structure to be cooled and the second structure to be cooled, with low energy consumption and good reliability.

[0017] (2) The chassis of the present invention is formed by the front panel, the base, the top cover, the first side panel and the second side panel; that is, the back of the chassis of the present invention adopts an open structure, which saves costs and facilitates the disassembly and maintenance of internal components. In addition, the maintenance door on the front panel also provides convenience for daily maintenance. The detachable connection of the top cover facilitates the removal of the top cover, thereby lifting the internal structure out from above, which facilitates the installation and replacement of the internal structure of the chassis.

[0018] (3) The sealing elements on the top cover, side plate one and side plate two of the present invention are used to achieve a seal between the chassis and the external installation vehicle body, which can prevent rainwater, dust and the like from entering the chassis from the back of the chassis.

[0019] (4) The chassis of the present invention is installed at the head position of the external mounting vehicle body, which makes it easy to fully integrate with the overall shape of the external mounting vehicle body, reduce the requirements for the installation position, and improve the aesthetics. By setting the light structure on the chassis, convenient driving conditions are provided for the vehicle body.

[0020] (5) In this invention, by installing an air intake filter structure on the side wall opening of the chassis, it is possible to filter out willow catkins or impurities in the air, and prevent willow catkins or impurities from entering the chassis and various structures inside the chassis, thereby avoiding affecting the normal operation of the cooling device; In this invention, the air intake filter structure preferably adopts a louver, which is simple in structure, easy to install and low in cost.

[0021] (6) In this invention, a mounting bracket 1 is fixed on the base of the chassis. The mounting bracket 1 provides a foundation for the installation of the drive component. The drive component is fixed on the mounting bracket 2. The mounting bracket 1 and the mounting bracket 2 are detachably connected, which makes it convenient to lift the entire drive component out from above or into the chassis through the mounting bracket 2 during maintenance. A shock-absorbing pad is set between the mounting bracket 1 and the mounting bracket 2 to avoid rigid vibration and noise caused by the long-term operation of the drive component and the wind turbine assembly.

[0022] (7) In this invention, a dual-output drive unit is used to achieve cooling of two sets of first structures to be cooled and one set of second structures to be cooled.

[0023] (8) In this invention, the air from the exhaust duct is diverted to the second cooling structure through the transition pipe, which reduces the requirements for the installation position of the second cooling structure. Furthermore, the transition pipe is made of a flexible material, which allows the transition pipe to be bent arbitrarily to adapt to complex installation environments.

[0024] (9) In this invention, by setting an expansion tank, the pressure in the circulating cooling circuit is kept stable, and the cooling circuit is replenished with liquid, thereby ensuring the cooling effect. The expansion tank is set on the impeller assembly of the cooling fan structure. During maintenance, the expansion tank can be lifted out of the casing along with the cooling fan structure.

[0025] (10) In this invention, ball valve one and ball valve two are set to control the flow of cooling medium in the circulating cooling circuit. The filter screen plays the role of filtering impurities in the circuit. The filter screen is located between ball valve one and ball valve two. When the filter screen needs to be removed for maintenance, ball valve one and ball valve two can block the cooling medium from both sides of the filter screen to prevent leakage, thereby making it easy to remove the filter screen.

[0026] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the figures. Attached Figure Description

[0039] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0040] Example:

[0041] A cooling device includes a chassis 1, a heat dissipation structure 2, and a cooling fan structure 3. Both the heat dissipation structure 2 and the cooling fan structure 3 are housed within the chassis 1. In this embodiment, there are two sets of heat dissipation structures 2, and the cooling fan structure 3 is located in the center of the chassis 1. The two sets of heat dissipation structures 2 are respectively located on the left and right sides of the cooling fan structure 3. Figure 1 As shown in Figure 9, the details are as follows:

[0042] The chassis 1 is installed on an external mounting car body (e.g., a shunting locomotive), specifically at the front of the external mounting car body.

[0043] like Figure 1 and Figure 2 As shown, the chassis 1 is formed by a front panel 1.1, a base 1.2, a first side panel 1.3, a second side panel 1.4, and a top cover 1.5. That is, the back of the chassis 1 adopts an open design. The base 1.2 is horizontally fixed to the front of the external mounting vehicle body; the front panel 1.1 is fixed to the base 1.2 and is located in front of the mounting vehicle body; the first side panel 1.3 and the second side panel 1.4 are both fixed to the base 1.2 and are fixed together with the front panel 1.1. The first side panel 1.3 and the second side panel 1.4 serve as the left and right side walls of the chassis 1, respectively; the top cover 1.5 is detachably connected to the front panel 1.1, the first side panel 1.3, and the second side panel 1.4 (e.g., bolted connection) so that the top cover 1.5 can be opened during maintenance.

[0044] In this embodiment, as Figure 3As shown, the top cover 1.5, side panel 1.3 and side panel 2 1.4 are all provided with sealing grooves 6 on the rear side away from the front panel 1.1. Sealing elements (such as sealing strips) are provided in the sealing grooves 6. That is, the sealing strips on the top cover 1.5, side panel 1.3 and side panel 2 1.4 form a U-shaped sealing structure. The function of the sealing strip is to achieve the sealing between the chassis 1 and the external mounting vehicle body, and to prevent rainwater, dust and other substances from entering the interior of the chassis 1 from the back.

[0045] Preferably, the top cover 1.5 is also provided with a lamp structure 1.51, and the illumination direction of the lamp structure 1.51 is consistent with the driving direction of the externally mounted vehicle body.

[0046] Side wall openings 1.a (rectangular openings) are provided on both the left and right side panels 1.3 and 1.4. The side wall openings 1.a are provided to facilitate the intake of ambient air by the cooling fan structure 3 inside the chassis 1 (as shown in F1). An air intake filter structure 7 is provided at the side wall opening 1.a. The air intake filter structure 7 can block impurities such as willow catkins from the outside environment. In this embodiment, the air intake filter structure 7 is preferably a louver or a filter screen 2.6 or other structure that can filter air impurities.

[0047] The heat dissipation structure 2 includes a pump component 2.2 (such as a water pump) and a radiator 2.1; both the pump component 2.2 (such as a water pump) and the radiator 2.1 are installed inside the chassis 1;

[0048] The first cooling structure 4 (preferably the converter on the shunting locomotive in this embodiment) is connected to the inlet of the radiator 2.1 through a circulation pipe one. The outlet of the radiator 2.1 is connected to the pump 2.2 through a circulation pipe two. The pump 2.2 is connected to the first cooling structure 4 through a circulation pipe three. That is, the first cooling structure 4, circulation pipe one, radiator 2.1, circulation pipe two, pump 2.2 and circulation pipe three are connected in sequence to form a circulating cooling circuit. The pump 2.2 provides power for the cooling medium to circulate in the circulating cooling circuit.

[0049] Preferably, the heat dissipation structure 2 further includes ball valve 2.4, ball valve 2.5, and filter screen 2.6; ball valve 2.4, ball valve 2.5, and filter screen 2.6 are all installed on the circulation pipe 3. Ball valve 2.4 and ball valve 2.5 are used to control the flow of cooling medium in the circulation cooling circuit; filter screen 2.6 is located between ball valve 2.4 and ball valve 2.5 and serves to filter impurities.

[0050] Preferably, the heat dissipation structure 2 in this embodiment further includes an expansion tank 2.3; the inlet of the expansion tank 2.3 is connected to the first circulation pipe through a pipe, and the outlet of the expansion tank 2.3 is connected to the second circulation pipe through a pipe; in this embodiment, the expansion tank 2.3 is installed on the cooling fan structure 3 (specifically, the volute 3.21 of the impeller assembly).

[0051] In this embodiment, the two sets of heat dissipation structures 2 are located on the left and right sides of the chassis 1, respectively, and the two sets of heat dissipation structures 2 are used to dissipate heat and cool down the two sets of first structures to be cooled 4.

[0052] like Figure 8 As shown, the cooling fan structure 3 includes a drive component 3.1 (e.g., a motor) and two sets of impeller assemblies 3.2; the drive component 3.1 has dual output ends, that is, in this embodiment, the drive component 3.1 is a motor with dual output shafts, preferably the output ends of the drive component 3.1 are axially perpendicular to the side plate 1.3 or the side plate 1.4 of the chassis 1;

[0053] like Figures 3 to 5 As shown, the specific installation structure of the drive component 3.1 inside the chassis 1 is as follows: a mounting bracket 1 8 is fixed on the base 1.2 of the chassis 1, and a mounting bracket 2 9 is detachably connected to the mounting bracket 1 8 (the detachable connection method here is, for example, bolt connection). The drive component 3.1 is fixedly installed on the mounting bracket 2 9; a shock-absorbing pad 10 (e.g., a rubber pad) is provided between the mounting bracket 1 8 and the mounting bracket 2 9.

[0054] The specific installation method of the shock-absorbing pad 10 is as follows: Figure 5 As shown: The shock-absorbing pad 10 is vertically fixed to the mounting bracket 8 by bolts. The mounting bracket 9 has mounting holes that are coaxially fitted onto the outer periphery of the shock-absorbing pad 10. The shock-absorbing pad 10 also has a stepped surface for supporting the lower end face of the mounting bracket 9. The shock-absorbing pad 10 and the mounting bracket 9 are fixed together by bolts. In this embodiment, there are four sets of shock-absorbing pads 10, which are located at the four corners of the mounting bracket 9.

[0055] The two output terminals of the drive unit 3.1 are respectively connected to two sets of impeller assemblies 3.2. When the drive unit 3.1 is working, it can drive both sets of impeller assemblies 3.2 to work simultaneously, thereby drawing ambient air from outside the chassis 1 into the impeller assemblies 3.2 from the side wall opening 1.a in the horizontal direction. The air intake direction is as follows: Figure 9 As shown in F1.

[0056] like Figure 8As shown, the wind turbine assembly 3.2 refers to the existing structure. In this embodiment, the wind turbine assembly 3.2 preferably includes a volute 3.21 and a wind turbine (not shown). The wind turbine is disposed in the volute 3.21 and is connected to one output end of the drive component 3.1. The volute 3.21 has an air inlet duct 3.2a in its axial direction and an exhaust duct 3.2b in its circumferential direction. When the wind turbine rotates, the ambient air enters the volute 3.21 from the air inlet duct 3.2a and is discharged from the exhaust duct 3.2b toward the second cooling structure 5 (in this embodiment, the second cooling structure 5 is preferably the traction motor on the shunting locomotive).

[0057] It should be noted that, as Figure 9 As shown, in the horizontal direction (i.e., the axial direction of the output end of the drive unit 3.1, i.e., the left-right direction, i.e., the air intake direction of the air intake duct 3.2a), the side wall opening 1.a, the radiator 2.1, and the air intake duct 3.2a are arranged sequentially. When the impeller rotates, the ambient air outside the chassis 1 enters the volute 3.21 of the impeller assembly 3.2 through the air intake filter structure 7 on the side wall opening 1.a, the radiator 2.1, and the air intake duct 3.2a. The ambient air passes through the radiator 2.1, exchanges heat with the radiator 2.1, and then enters the volute 3.21, and is discharged from the exhaust duct 3.2b toward the second structure to be cooled 5. It should be noted that in this embodiment, the cooling of the first structure to be cooled 4 is indirectly achieved by the ambient air exchanging heat with the radiator 2.1.

[0058] like Figures 6 to 7 As shown, in this embodiment, the radiator 2.1 has a conical shell 2.11 on the side near the volute 3.21 (the axial side of the volute). Specifically, the radiator 2.1 is fixed inside the chassis 1, the large opening of the conical shell 2.11 connects to the radiator 2.1, and the small opening of the conical shell 2.11 communicates with the air inlet duct 3.2a. A sealing ring is used to seal the small opening of the conical shell 2.11 and the air inlet duct 3.2a (i.e., between the conical shell 2.11 and the volute 3.21). Referring to existing technology, the radiator 2.1 in this embodiment is selected to allow ambient airflow to pass through it and exchange heat with it before entering the volute 3.21 from inside the conical shell 2.11.

[0059] Preferably, the cooling fan structure 3 in this embodiment further includes a transition pipe (not shown), which is configured in a one-to-one correspondence with the exhaust duct 3.2b of the impeller assembly 3.2. That is, one end of the transition pipe is connected to the exhaust duct 3.2b, and the other end of the transition pipe discharges the ambient air after heat exchange toward the second cooling structure 5. In this embodiment, the transition pipe is made of a flexible material, which can accommodate bending of any shape.

[0060] In this embodiment, the two sets of heat dissipation structures 2 are located at the left and right ends of the drive component 3.1, respectively, and the air intake filter structure 7, the heat dissipation structure 2 and the impeller assembly 3.2 are set in a one-to-one correspondence.

[0061] The working principle of the cooling device in this embodiment is as follows:

[0062] The working principle of the circulating cooling circuit is as follows (arrow F3 indicates the direction of cooling medium flow): Pump 2.2 starts working, and the cooling medium circulates in the circulating cooling circuit. When the cooling medium flows through the first structure to be cooled 4, the cooling medium exchanges heat with the first structure to be cooled 4. The cooled medium that has exchanged heat enters the radiator 2.1 for heat exchange. In addition, the radiator 2.1 exchanges heat with the ambient air entering from the side wall opening 1.a of the chassis 1 to reduce the temperature of the radiator 2.1 itself. Then, pump 2.2 continues to work, and the cooling medium circulates, thereby continuously cooling the first structure to be cooled 4.

[0063] The left and right sets of circulating cooling circuits operate on the same principle.

[0064] The working principle of the cooling fan structure 3 is as follows: the driving component 3.1 drives the left and right sets of impeller assemblies 3.2 to rotate simultaneously. The impeller assembly 3.2 draws the ambient air from outside the chassis 1 through the air intake filter structure 7 on the side wall opening 1.a, the radiator 2.1 and the air intake duct 3.2a into the interior of the impeller assembly 3.2, and blows it out from the exhaust duct 3.2b of the impeller assembly 3.2 toward the second structure to be cooled 5, so as to achieve the purpose of cooling the second structure to be cooled 5.

[0065] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
