Description

Technical Field

[0001] This utility model belongs to the field of vehicle radiator technology, specifically relating to a two-in-one radiator device for underground coal mine vehicles. Background Technology

[0002] Cooling devices for underground coal mine vehicles are mainly used to cool the liquid cooling systems of the drive motors or diesel engines in these vehicles. The cooling capacity of these devices is mostly designed to be matched to the vehicle's specifications. When additional equipment is added to the vehicle requiring thermal management, regardless of whether the equipment uses the same liquid cooling system or a different cooling medium, the original vehicle's cooling system cannot meet the requirements and therefore cannot be used directly.

[0003] Currently, most underground coal mine vehicles are not equipped with onboard air conditioning. The condenser core of the air conditioning system is also a device that needs heat dissipation, and its heat dissipation medium is refrigerant. Due to the difference in the medium and the increase in heat dissipation power, when underground coal mine vehicles need to install air conditioning, the original vehicle's heat dissipation device cannot be used directly. Traditional modification solutions, due to the addition of air conditioning, result in insufficient heat dissipation power, layout conflicts, and high modification costs.

[0004] Therefore, a specially designed cooling device for underground coal mine vehicles is needed, which can meet the requirements of air conditioning installation and the use of the original liquid cooling system. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing cooling devices for underground coal mine vehicles that cannot meet actual needs, and to provide a two-in-one cooling device for underground coal mine vehicles that integrates an air conditioning cooling system and a power cooling system, and is small in size and highly adaptable.

[0008] case;

[0009] The cooling fan, the drive cooling assembly, and the air conditioning condenser assembly are installed sequentially on the housing from top to bottom.

[0010] The drive cooling component is fixedly installed on the lower end face of the housing via a snap-fit ​​component and is connected to the vehicle drive cooling system piping; the air conditioning condenser component is fixedly installed on the lower part of the housing via a fixing component and is connected to the vehicle air conditioning system piping.

[0011] Furthermore, the drive heat dissipation assembly includes a drive heat dissipation core, a coolant inlet and a coolant replenishment inlet located on one side of the drive heat dissipation core, and a coolant outlet located on the other side of the drive heat dissipation core.

[0012] The coolant inlet and outlet joints form a circulation loop with the vehicle drive system through pipelines. An explosion-proof pump motor or explosion-proof pump motor is installed on the circulation loop to drive the circulation of coolant.

[0017] Furthermore, the housing includes an upper shell, a first side shell, a second side shell, a front shell, and a rear shell;

[0018] The upper shell has a cavity for installing a cooling fan; both the first and second side shells have clearance grooves to avoid the coolant inlet or outlet joint.

[0019] Furthermore, the air conditioning condensing assembly includes a condensing heat dissipation core, a condensate inlet connector and a condensate outlet connector disposed on one side of the condensing heat dissipation core;

[0020] The condensate inlet is connected to the compressor line in the vehicle's air conditioning system via a pipeline, and the condensate outlet is connected to the liquid line of the liquid reservoir in the vehicle's air conditioning system via a pipeline.

[0021] Furthermore, the fixing assembly includes: two first fixing plates symmetrically fixedly mounted on the front shell and two second fixing plates symmetrically disposed on the rear shell;

[0023] Furthermore, connecting parts are provided between the condensate inlet and the housing, and between the condensate outlet and the housing;

[0024] The connector includes a connecting plate fixedly mounted on the housing at one end and an arc-shaped opening at the other end of the connecting plate; the condensate inlet or condensate outlet is fixedly mounted to the connecting plate by bolts.

[0025] Furthermore, the cooling fan includes a heat dissipation shell mounted on the housing, an explosion-proof motor mounted inside the heat dissipation shell, and blades coaxially arranged with the output shaft of the explosion-proof motor.

[0026] Furthermore, both the heat dissipation outer shell and the housing are made of non-light metal materials, meeting the explosion-proof requirements of MA for mining.

[0027] Furthermore, both the drive heat dissipation core and the condensation heat dissipation core include pipes on both sides and several fins disposed between the pipes; the pipes are made of copper pipes and the fins are made of light metal materials, meeting the friction ignition performance requirements of mining MA.

[0028] The beneficial effects of this utility model of a two-in-one cooling device for underground vehicles in coal mines are:

[0041] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0042] like Figures 1-8 The present invention provides a specific embodiment of a two-in-one cooling device for underground vehicles in coal mines, comprising a housing 1, a cooling fan 2, a drive cooling component 3, and an air conditioning condenser component 4, which are installed sequentially from top to bottom on the housing 1. Specifically, the drive cooling component 3 is fixedly installed on the lower end face of the housing 1 by a snap-fit ​​component 5 and is connected to the vehicle's drive cooling system pipeline; the air conditioning condenser component 4 is fixedly installed on the lower part of the housing 1 by a fixing component 6 and is connected to the vehicle's air conditioning system pipeline.

[0043] Furthermore, the vehicle drive cooling system is existing technology. When adding air conditioning to a coal mine, the vehicle drive cooling system is not modified; it is simply connected to the two-in-one cooling device for coal mine vehicles in this embodiment. Therefore, the other structures of the vehicle drive cooling system will not be described in detail here. Similarly, the vehicle air conditioning system includes not only the air conditioning condenser assembly 4 in this embodiment, but also the compressor, liquid receiver tank, and other structures inherent to the air conditioning system. These are technologies well-known to those skilled in the art, and the other structures in the air conditioning system will not be described in detail here either.

[0044] This embodiment integrates the drive cooling component 3 and the air conditioning condenser component 4 into a single design. This integrates the liquid cooling of the drive system and the cooling of the air conditioning condenser core 41 into a single device, solving the problem of requiring separate cooling modules when adding an air conditioner to traditional vehicles. It achieves efficient compatibility of multiple system cooling needs within the limited space of underground coal mine vehicles, while meeting underground coal mine safety standards. This also solves the problems of insufficient cooling power, layout conflicts, and high modification costs associated with adding an air conditioner in traditional solutions. The cooling fan 2 is located on the upper part of the housing 1, forming forced convection and simultaneously improving the cooling capacity of the liquid cooling system and the condenser core 41, adapting to the high temperature and humidity environment underground.

[0045] like Figure 2 and Figure 5 As shown, in this embodiment, the drive cooling assembly 3 includes a drive cooling core 31, a coolant inlet connector 32 and a coolant replenishment connector 33 located on one side of the drive cooling core 31, and a coolant outlet connector 34 located on the other side of the drive cooling core 31. The coolant inlet connector 32 and the coolant outlet connector 34 form a circulation loop with the vehicle drive system through pipelines. An explosion-proof pump motor or explosion-proof pump motor is installed on the circulation loop to drive the circulation of coolant. That is, the coolant inlet connector 32 and the coolant replenishment connector 33 in the drive cooling assembly 3 are connected to an external pump motor or pump motor through pipelines to circulate the coolant in the vehicle drive cooling system and achieve the function of heat dissipation. The coolant replenishment connector 33 is connected to the external coolant storage tank through pipelines to replenish the coolant in the vehicle drive cooling system.

[0046] Specifically, see Figure 6 The snap-fit ​​assembly 5 includes an L-shaped fixing member 51 and a snap-fit ​​member 52 fixedly disposed on the outside of the housing 1. The snap-fit ​​member 52 includes an arc-shaped snap-fit ​​portion 521 that engages with both sides of the drive heat sink core 31 and a horizontal portion 522 fixedly connected to the arc-shaped snap-fit ​​portion 521. The L-shaped fixing member 51 and the horizontal portion 522 are fixedly connected by bolts. Both the L-shaped fixing member 51 and the horizontal portion 522 have through holes for bolts to pass through. During installation, the L-shaped fixing member 51 is first fixed to the outside of the housing 1, and then the arc-shaped snap-fit ​​portion 521 of the snap-fit ​​member 52 engages with the drive heat sink core 31. The through holes of the snap-fit ​​member 52 and the through holes of the L-shaped fixing member 51 are aligned, and the two are fixed by bolts. The installation is simple and reliable.

[0047] It should be further explained that the housing 1 in this embodiment is used to fix and integrate the two components, and also serves to protect the core. Specifically, as shown... Figure 4As shown, the housing 1 includes an upper housing 11, a first side housing 12, a second side housing 13, a front housing 14, and a rear housing 15. The upper housing 11 has a cavity for installing the cooling fan 2. The first side housing 12 and the second side housing 13 both have clearance grooves for avoiding the coolant inlet connector 32, the coolant outlet connector 34, or the coolant replenishment connector 33.

[0048] This embodiment adopts a modular design with a housing 1, which supports mass production, adapts to the limited space of underground vehicles, and avoids the need to reconfigure the overall vehicle layout due to the addition of air conditioning. It is applicable to different models of underground coal mine vehicles.

[0049] like Figure 8 As shown, the air conditioning condenser assembly 4 includes a condenser heat dissipation core 41, a condensate inlet connector 42 and a condensate outlet connector 43 disposed on one side of the condenser heat dissipation core 41; the condensate inlet connector 42 is connected to the compressor pipeline in the vehicle's air conditioning system via a pipeline, and the condensate outlet connector 43 is connected to the liquid line of the liquid receiver in the vehicle's air conditioning system via a pipeline. The condensate inlet connector 42 and the condensate outlet connector 43 are connected to the external compressor and liquid receiver via pipelines, forming the refrigerant flow of the air conditioning system, thereby realizing the air conditioning cooling function.

[0050] The fixing assembly 6 includes two first fixing plates symmetrically fixedly installed on the front shell 14 and two second fixing plates symmetrically arranged on the rear shell 15. Both the first fixing plates and the second fixing plates extend downward out of the shell 1. The condensation heat dissipation core 41 is fixedly connected to the first fixing plates and the second fixing plates by bolts.

[0051] To ensure the installation stability of the condenser heat dissipation core 41, connecting parts 7 are provided between the condensate inlet connector 42 and the housing 1, and between the condensate outlet connector 43 and the housing 1. For example, Figure 7 As shown, the connector 7 in this embodiment includes a connecting plate 71 fixedly mounted on the housing 1 at one end and an arc-shaped opening 72 at the other end of the connecting plate 71; the condensate inlet connector 42 or the condensate outlet connector 43 is fixedly mounted to the connecting plate 71 by bolts.

[0052] This embodiment includes a cooling fan 2 to accelerate heat dissipation, thereby increasing the airflow and cooling speed. The cooling fan 2 comprises a heat dissipation shell mounted on the housing 1, an explosion-proof motor installed inside the heat dissipation shell, and blades coaxially arranged with the output shaft of the explosion-proof motor. The explosion-proof motor is an explosion-proof motor that meets the MA certification requirements for underground coal mine equipment. Both the housing 1 and the heat dissipation shell are made of non-light metal materials, such as carbon steel, meeting the impact performance requirements of GB / T3836.1-2021 and the protection level requirements of GB / T4208-2017.

[0053] To meet the explosion-proof requirements of underground coal mines, both the drive heat dissipation core 31 and the condensation heat dissipation core 41 in this embodiment include pipes on both sides and several fins disposed between the pipes; the pipes are made of copper, and the fins are made of light metal materials, meeting the friction ignition performance requirements of mining MA. It should be understood that the pipe joints in this embodiment also use non-light metal materials, such as copper or carbon steel, that meet the impact performance requirements of GB / T3836.1-2021 and the protection level requirements of GB / T4208-2017.

[0054] When in use, the two-in-one heat dissipation device in this embodiment can be installed at the front of the vehicle in the mine, or in other locations with good air circulation. After installation, ensure that the air intake direction of the vehicle is consistent with the airflow direction of the cooling fan 2.

[0055] It should be understood that the specific embodiments described above are only for explaining the present invention and are not intended to limit the present invention. Obvious variations or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
