DETAILED DESCRIPTION

[0033] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below in conjunction with specific embodiments.

[0034] Please refer to Figures 1-9 The embodiment of the present application provides a digital intelligent temperature control heat dissipation system, which comprises a heat dissipation device, a temperature control assembly, an oil inlet pipeline 3 and an oil outlet pipeline 4. The heat dissipation device comprises a fan 1 and a composite heat dissipation assembly 2 arranged at the air outlet end of the fan 1. The composite heat dissipation assembly 2 is in communication with a hydraulic station through the oil inlet pipeline 3 and the oil outlet pipeline 4.

[0035] The digital intelligent temperature control heat dissipation system is used for heat dissipation and temperature control of the hydraulic oil of a hydraulic system 10, and is preferably suitable for temperature control of the hydraulic system 10 of an engineering vehicle. The composite heat dissipation assembly 2 of the heat dissipation device is in communication with the hydraulic station through the oil inlet pipeline 3 and the oil outlet pipeline 4. The composite heat dissipation assembly 2 is arranged at the air outlet end of the fan 1, and the hydraulic oil is cooled and heat-dissipated through the air cooling effect of air cooling and the water cooling effect of water cooling.

[0036] In the embodiment of the present application, the composite heat dissipation assembly 2 comprises an oil delivery net pipe member 23 and a water cooling channel member 24 which are perpendicular to the air outlet direction of the fan 1, the oil inlet end of the oil delivery net pipe member 23 is communicated with the oil inlet pipeline 3, the oil outlet end of the oil delivery net pipe member 23 is communicated with the oil outlet pipeline 4, the oil delivery net pipe member 23 comprises a water cooling pre-cooling area 232 and an air cooling area 233 which is communicated with the water cooling pre-cooling area 232, the water cooling channel member 24 comprises a water cooling cavity 241 which is surrounded outside the water cooling pre-cooling area 232 and a net pipe air cooling part 242 which is communicated with the water cooling cavity 241, the net pipe air cooling part 242 is oppositely arranged with the air cooling area 233, and the pipe connection of the net pipe air cooling part 242 and the pipe connection of the air cooling area 233 are staggered arranged in the air outlet direction of the fan 1;

[0037] The oil delivery net pipe member 23 and the water cooling channel member 24 of the composite heat dissipation assembly 2 are perpendicular to the air outlet direction of the fan 1, so that the vertical arrangement of the line and the surface can improve the air cooling effect. The structure of the oil delivery net pipe member 23 is similar to that of a capillary net pipe, which has a channel for the flow of hydraulic oil. The hydraulic oil with heat can enter the oil delivery net pipe member 23 through the oil inlet pipeline 3, and then flow out through the oil outlet pipeline 4 after heat dissipation and cooling. The oil delivery net pipe member 23 includes a water cooling pre-cooling area 232 and an air cooling area 233 in communication with the water cooling pre-cooling area 232. The water cooling pre-cooling area 232 is arranged in the water cooling chamber 241 of the water cooling channel member 24, and the air cooling area 233 is located outside the water cooling chamber 241. The water cooling chamber 241 of the water cooling channel member 24 and the air cooling area 233 are filled with a cooling liquid, which can be water, a cooling medium such as refrigerant, or an existing cooling liquid. The selection and configuration of the cooling liquid are not limited and can be selected according to the heat dissipation requirements or actual conditions. When the hydraulic oil enters the water cooling pre-cooling area 232, heat exchange can be performed through the cooling liquid wrapped outside the net pipe of the water cooling pre-cooling area 232, so as to realize pre-cooling of the hydraulic oil. The hydraulic oil that has been cooled further enters the net pipe of the air cooling area 233 and is further air-cooled by the fan 1, so as to realize better heat dissipation effect and make the heat dissipation system meet the higher heat dissipation requirements of the hydraulic system 10. The cooling liquid in the water cooling chamber 241 of the water cooling channel member 24 can be air-cooled and heat-dissipated through the net pipe air-cooling part 242, so as to reduce the temperature of the cooling liquid, prolong the cooling time of the cooling liquid, and maintain the temperature of the cooling liquid in a small fluctuation range. Since the net pipe of the oil delivery net pipe member 23 and the net pipe air-cooling part 242 of the water cooling channel member 24 are both capillary net pipe structures, and the pipe connection parts of the net pipe air-cooling part 242 and the air cooling area 233 are staggered in the air outlet direction of the fan 1, the contact area between the net pipe and the air is larger, the heat dissipation effect is better, and the cooling of the cooling liquid and the hydraulic oil can be realized at the same time under the action of air cooling. The air cooling of the net pipe air-cooling part 242 and the air cooling of the air cooling area 233 basically do not affect or interfere with each other, and the structural design is more reasonable.

[0038] In order to realize intelligent temperature control, in the embodiment of the present application, the temperature control assembly is connected with the fan 1, and the temperature control assembly is used to control the rotating speed of the fan 1 according to the temperature of the hydraulic oil in the oil inlet pipeline 3 and the oil outlet pipeline 4.

[0039] The rotating speed of the fan 1 can be adjusted by the temperature control assembly according to the temperature of the hydraulic oil, so as to realize automatic temperature control of the hydraulic oil and better realize temperature control of the hydraulic oil.

[0040] Through the technical solution, the composite heat dissipation assembly 2 can realize effective combination of water cooling and air cooling, can pre-cool the oil delivery net pipe member 23 through water cooling of the water cooling chamber 241, can further air cool through the heat dissipation structure similar to the capillary pipe under the action of air cooling, and the cooling liquid of the water cooling chamber 241 after absorbing heat can be air cooled through the net pipe air cooling part 242, so that the cooling liquid can be more persistent in water cooling heat dissipation, and the pipe connection positions of the net pipe air cooling part 242 and the air cooling area 233 are staggered with each other, so that the two can be air cooled and heat dissipated at the same time under the air cooling action of the fan 1, and the air cooling action is maximized, the heat dissipation upper limit of the heat dissipation system is effectively improved, and the heat dissipation demand of the high-pressure hydraulic system 10 is better met.

[0041] In an embodiment, the oil delivery net pipe member 23 and the net pipe air cooling part 242 are both channel members with flow channels 231 formed by a plurality of branch pipes intersecting and communicating, and the branch pipes are spaced to form air passing parts 25.

[0042] In this way, the channel member formed by the plurality of branch pipes intersecting and communicating can facilitate forming the channel structure of the capillary pipe network, improve the surface area in contact with air, and prolong the path length in the flow channel 231, thereby increasing the time of hydraulic oil flowing inside and improving the heat dissipation effect, and the air passing parts 25 formed between the branch pipes can facilitate air passing and heat exchange during air passing.

[0043] Further, to more fully utilize the air cooling action of the fan 1 to air cool and heat dissipate the net pipe air cooling part 242 and the air cooling area 233, the air passing part 25 is a polygonal air passing opening, and the projection of the branch pipe connection center of the net pipe air cooling part 242 on the air outlet direction of the fan 1 is located at the center of the air passing opening of the air cooling area 233.

[0044] In this way, the polygonal air passing opening can make the air cooling area 233 of the oil delivery net pipe member 23 and the flow path of the net pipe air cooling part 242 have at least one bend, thereby prolonging the length of the flow channel 231 to increase the residence time of hydraulic oil inside, and the projection of the branch pipe connection center of the net pipe air cooling part 242 on the air outlet direction of the fan 1 is located at the center of the air passing opening of the air cooling area 233, which can more greatly reduce the mutual influence between the net pipe air cooling part 242 and the air cooling area 233 under the air cooling action, thereby achieving more full utilization of air cooling.

[0045] Preferably, the oil feeding direction of the oil feeding net pipe member 23 is from top to bottom, and the air passing hole is a vertically arranged prismatic structure. By the downward flow of the hydraulic oil in the flow passage 231 of the oil feeding net pipe member 23, the flowability and the convenience of the delivery can be improved by gravity, and by the vertically arranged prismatic structure of the air passing hole, the downward flow of the hydraulic oil under the action of gravity can be facilitated, and the flow path length of the hydraulic oil in the oil feeding net pipe member 23 can be prolonged, thereby prolonging the residence time of the hydraulic oil in the oil feeding net pipe member 23, and better performing air cooling and water cooling.

[0046] In order to improve the heat exchange effect of the hydraulic oil in the cooling and / or water cooling process, the water cooling pre-cooling area 232 is provided with heat dissipation fins one (not shown in the figure) on the pipe wall; and / or, the net pipe air cooling part 242 is provided with heat dissipation fins two (not shown in the figure) on the pipe wall, and the air cooling area 233 is provided with heat dissipation fins three (not shown in the figure) on the pipe wall.

[0047] In this way, the heat of the hydraulic oil can be transferred to the heat dissipation fins through the pipe wall made of heat-conducting metal material, thereby improving the heat exchange efficiency and the heat dissipation effect under the action of air cooling.

[0048] In order to improve the cooling effect of the cooling liquid, in an embodiment, the water cooling passage member 24 is connected with a circulating pipeline 5, and the circulating pipeline 5 is provided with a circulating pump 52 and a cooling liquid storage tank 51.

[0049] The water cooling passage member 24 can realize a closed circulating flow path by connecting the circulating pipeline 5, and the cooling liquid can circulate in the flow path, thereby realizing the replacement circulation of the cooling liquid in the water cooling chamber 241 through the flow of the cooling liquid, improving the water cooling effect, and further reducing the temperature of the cooling liquid after absorbing heat under the action of air cooling in the air cooling area 233, so that the temperature fluctuation range of the cooling liquid is smaller, the temperature control is more stable, and the high and low temperature cooling liquids after absorbing heat can be hedged through the cooling liquid storage tank 51, thereby balancing and relieving the temperature fluctuation, and further significantly stabilizing the temperature fluctuation range of the cooling liquid, controlling the fluctuation range to be smaller, and improving the cooling capacity of the water cooling of the heat dissipation system, so that it is more suitable for long-time operation and temperature reduction under high pressure.

[0050] The net-pipe area of the water-cooling chamber 241 can be arranged outside the air outlet area of the fan 1, so that the air flow passing through will not be blocked. In order to make full use of the air cooling, the net-pipe area of the water-cooling chamber 241 can be arranged in the air outlet area, such as the upper part of the air outlet area. On this basis, the water-cooling chamber 241 is provided with penetrating ventilation pipes 2412, the ventilation pipes 2412 pass through the net-pipe gap of the water-cooling pre-cooling area 232, and the water-cooling chamber 241 is provided with a smooth transition conical transition area 2411 between the outer wall of the windward side and the pipe opening of the ventilation pipe 2412. By arranging the penetrating ventilation pipes 2412 in the water-cooling chamber 241, the air flow passing through can be facilitated, the noise can be reduced, and the heat transferred by the water-cooling chamber 241 can also be taken away in the process of air flow passing through. Of course, the side wall of the water-cooling chamber 241 is made of heat-conducting metal material, so that the heat can be taken away. The ventilation pipes 2412 pass through the net-pipe gap of the water-cooling pre-cooling area 232, which can also be arranged by using the gap structure of the net-pipe, and the design is more reasonable. At the same time, the water-cooling chamber 241 is provided with a smooth transition conical transition area 2411 between the outer wall of the windward side and the pipe opening of the ventilation pipe 2412, which can guide the air flow and facilitate the air flow passing through, and can further reduce the noise generated.

[0051] Preferably, the total area of the conical transition area 2411 accounts for more than two-thirds of the area of the outer wall of the windward side of the water-cooling chamber 241. Such proportion can more significantly reduce the blockage of the air flow and further reduce the noise generated.

[0052] In the specific implementation process, the oil conveying net-pipe component 23 further includes an oil inlet shunt channel 26 in communication with the pipeline of the water-cooling pre-cooling area 232 and an oil outlet shunt channel 27 in communication with the pipeline of the air-cooling area 233. The oil inlet shunt channel 26 is the first flow channel for the hydraulic oil entering the composite heat dissipation assembly 2, which is in communication with the net-pipe branches of the water-cooling pre-cooling area 232, thereby playing a shunt role. The oil outlet shunt channel 27 is in communication with the net-pipe branches of the air-cooling area 233, thereby playing a backflow discharge role.

[0053] In order to realize intelligent temperature control, the temperature control assembly is combined with the temperature detection device one 6, the temperature detection device two 8, the temperature detection device three 7 and the controller. Figure 9 As shown in the drawings, in the embodiment of the present application, the temperature control assembly includes a temperature detection device one 6, a temperature detection device two 8, a temperature detection device three 7 and a controller. The temperature detection device one 6 is used to collect the temperature data one of the hydraulic oil in the oil inlet pipeline 3, the temperature detection device two 8 is used to collect the temperature data two of the hydraulic oil in the oil outlet pipeline 4, the temperature detection device three 7 is used to collect the temperature data three of the cooling liquid in the water-cooling chamber 241, and the controller is used to adjust the rotating speed of the fan 1 according to the temperature data one, the temperature data two and the temperature data three.

[0054] The temperature of the hydraulic oil entering and flowing out of the composite heat dissipation assembly 2 can be obtained by the temperature detection device one and the temperature detection device two 8, the rotating speed of the fan 1 is controlled according to the real-time temperature of the hydraulic oil, and the real-time temperature of the cooling liquid when pre-cooling the hydraulic oil can be obtained through the temperature detection device three 7, and the circulating pump 52 is controlled to circulate according to the temperature, so that intelligent temperature control and heat dissipation can be realized. In the specific implementation process, the controller can adopt a PLC controller 9, and the PLC controller 9 can be connected with a large-screen display or a touch screen, so as to centrally display and control the related data. In addition, a temperature sensor four can also be arranged on the cooling liquid storage tank 51, so as to know the temperature of the cooling liquid therein, and avoid the overload condition caused by long-time work under high-intensity operation.

[0055] In the specific implementation process, the composite heat dissipation assembly 2 further comprises a shell 21, the shell 21 is open at the air inlet side, and an air outlet grille 22 is arranged at the air outlet, and the circulating pipeline 5 and the oil inlet pipeline 3 and the oil outlet pipeline 4 all pass through the shell and are communicated with the corresponding components on the inner side.

[0056] The digital intelligent temperature control and heat dissipation system of the embodiment of the present application can start the water cooling circulation of the cooling liquid according to the working condition during use, for example, the circulating pump 52 can not be started to circulate under the condition of low operation intensity, so that the energy consumption can be reduced, and the circulating pump 52 can be started to circulate under the condition of high operation intensity.

[0057] Compared with the heat dissipation device of the traditional hydraulic system 10, the overall size does not change too much, so that the space occupation is not increased, and the circulating pipeline 5 can be selected and configured according to the demand.

[0058] The above is only the preferred embodiment of the present application, and it should be pointed out that the above preferred embodiment should not be regarded as the limitation of the present application, and the protection scope of the present application should be limited by the scope defined by the claims. For ordinary skilled in the art, several improvements and refinements can be made without departing from the spirit and scope of the present application, and these improvements and refinements should also be regarded as the protection scope of the present application.
