Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, and relates to cooling packs in engineering machinery. Specifically, it relates to an auxiliary device for emergency cooling of cooling packs in engineering machinery. Background Technology

[0002] In the field of construction machinery, the efficient operation of equipment relies on the coordinated work of key components, among which the cooling system plays a crucial role. As construction machinery continues to develop towards larger sizes and higher power, its heat dissipation requirements are becoming increasingly prominent. As a core heat dissipation unit, the performance of the cooling pack directly affects the stability and service life of the equipment.

[0003] The cooling pack in construction machinery primarily functions to maintain the operation of critical components such as the engine and hydraulic system within a suitable temperature range, preventing performance degradation or malfunctions due to overheating. The cooling pack uses a forced-circulation cooling medium to transfer heat from high-temperature components to the radiator, where it exchanges heat with the outside air through the radiator fins to cool down before returning to the system for further circulation. This mechanism effectively avoids localized overheating, ensures stable viscosity of hydraulic and engine oils, thereby optimizing the machine's transmission efficiency and response speed, improving the reliability of construction machinery operation, and supporting the high-intensity operational demands of modern construction machinery in infrastructure construction.

[0004] Current cooling packs are susceptible to heat dissipation efficiency issues due to external conditions. When construction machinery operates in extreme heat, the coolant evaporates too quickly, failing to meet the cooling demands of large machinery. This leads to frequent activation of overheat protection mechanisms, disrupting operational continuity. The only current solution to improve the cooling capacity of these packs is to replace them with larger ones. However, existing construction machinery often lacks sufficient space to accommodate larger cooling packs due to space constraints. Consequently, existing machinery struggles to operate normally in extreme heat environments, impacting construction progress and reducing its adaptability to different working conditions. Summary of the Invention

[0005] This utility model addresses at least one of the aforementioned technical problems in the background art by proposing an auxiliary device for cooling an emergency cooling pack in extreme high-temperature conditions, thereby ensuring the cooling performance of the cooling pack under extreme high-temperature conditions.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: In one aspect, this utility model proposes an auxiliary device for cooling an emergency cooling package at extreme high temperatures, comprising: The spray pipe is located above the cooling core and is used to spray cooling water onto the surface of the cooling core. A water collection tank is used to collect cooling water flowing down from the surface of the cooling core. A water storage tank, used to store cooling water; A water pump, which is connected to the water storage tank, is used to draw cooling water from the water storage tank and deliver it to the spray pipe for spraying. A temperature sensing module, which is installed on the cooling core, is used to detect the temperature of the cooling medium entering and exiting the cooling core; The control module receives the inlet and outlet temperatures of the cooling medium from the temperature sensing module and adjusts the operating state of the water pump based on the temperature difference.

[0007] In some embodiments of this application, an inlet temperature sensor and an outlet temperature sensor can be provided in the temperature sensing module. The inlet temperature sensor detects the temperature of the cooling medium entering the cooling pack core and generates an inlet temperature detection signal, which is sent to the control module. The outlet temperature sensor detects the temperature of the cooling medium exiting the cooling pack core and generates an outlet temperature detection signal, which is sent to the control module. The control module calculates the temperature difference between the inlet and outlet refrigerants. When the temperature difference stabilizes above a preset threshold, it indicates that the cooling capacity of the cooling pack has been restored. At this point, the control module can control the water pump to stop running, ending the process of spraying cooling water onto the cooling pack core.

[0008] In some embodiments of this application, the inlet temperature sensor and the outlet temperature sensor can be arranged diagonally on the cooling core, with the inlet temperature sensor located at the bottom of the cooling core and the outlet temperature sensor located at the top of the cooling core, in order to improve the accuracy of detecting the temperature difference between the cooling medium entering and exiting the cooling core.

[0009] In some embodiments of this application, to prevent cooling water from splashing everywhere, a shroud can be further provided around the cooling core to cover it. A fixing bracket can be further installed on the top of the inner wall of the shroud, and the spray pipe can be installed on the fixing bracket to position the spray pipe directly above the cooling core, so that the sprayed cooling water can cover the entire surface of the cooling core as much as possible, thereby improving the cooling efficiency of the cooling core.

[0010] In some embodiments of this application, the water receiving tank can be connected to the water pump via a return water pipe, and the control module can be configured to control the water pump to draw the cooling water collected in the water receiving tank back to the water storage tank after the spraying is completed, so as to realize the recycling of cooling water.

[0011] In some embodiments of this application, the water receiving tank can be arranged below the cooling core to collect as much cooling water as possible and reduce waste.

[0012] In some embodiments of this application, the water pump may be a high-pressure electronic water pump, which includes a motor and a flow path switching valve. The control module is configured to generate a control signal based on the detected temperature difference of the cooling medium and send it to the high-pressure electronic water pump to control the flow path switching valve in the high-pressure electronic water pump to connect the water storage tank to the spray pipe or the water storage tank to the return water pipe. This is combined with the forward and reverse rotation control of the motor to achieve automatic switching between the two working modes of cooling water spraying and cooling water recycling.

[0013] In some embodiments of this application, a level sensor can be further installed in the water storage tank to detect the remaining amount of cooling water in the tank and generate a level detection signal to be sent to the control module. The control module is configured to issue an early warning when the cooling water is insufficient to remind staff to replenish the cooling water in a timely manner to ensure the normal operation of the auxiliary device.

[0014] In another aspect, this utility model also proposes an engineering machine, including a cooling core and an auxiliary device for rapidly cooling the cooling core; wherein the auxiliary device includes: The spray pipe is located above the cooling core and is used to spray cooling water onto the surface of the cooling core. A water collection tank is used to collect cooling water flowing down from the surface of the cooling core. A water storage tank, used to store cooling water; A water pump, connected to the water storage tank, is used to draw cooling water from the water storage tank and deliver it to the spray pipe for spraying. A temperature sensing module, which is installed on the cooling core, is used to detect the temperature of the cooling medium entering and exiting the cooling core; The control module receives the inlet and outlet temperatures of the cooling medium from the temperature sensing module and adjusts the operating status of the water pump based on the temperature difference.

[0015] In some embodiments of this application, the water pump and water tank can be located near the driver's cab. This facilitates the driver in replenishing the water tank with coolant and allows for easy maintenance and disassembly of auxiliary devices. The control module can be a control system with an instrument panel installed on the dashboard inside the driver's cab. When the coolant level in the water tank is severely low, a warning can be issued to the driver via the instrument panel.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are mainly reflected in: 1. This utility model equips the cooling pack core with a cooling water spray system, and simultaneously detects the temperature of the cooling medium entering and exiting the cooling pack core. Based on the temperature difference, it judges the cooling capacity of the cooling pack. When the cooling capacity is insufficient, the spray system is automatically activated to spray cooling water onto the surface of the cooling pack core, thereby helping the cooling pack core to quickly reduce the temperature of the cooling medium flowing inside, restore the cooling performance of the cooling pack, and thus continuously meet the heat dissipation requirements of the equipment.

[0017] 2. The cooling pack cooling auxiliary device of this utility model can achieve intelligent control without human intervention, with a high degree of automation and precise control. The whole device has a simple structure and can be quickly installed on existing equipment; when not in use, it can also be quickly disassembled for easy recycling.

[0018] 3. Applying the auxiliary device of this utility model to construction machinery can assist in cooling the core of the cooling pack in construction machinery. The modification cost is low and the modification cycle is short. It can enhance the cooling capacity of the cooling pack in extreme high temperature environments, avoid the power reduction problem of construction machinery, ensure the continuous and efficient operation of construction machinery under harsh working conditions, and improve the adaptability of construction machinery to harsh working environments.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, an integral molding, or an internal connection of components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. In the description of the embodiments, specific features, structures, materials, or characteristics can be combined in any suitable manner in one or more embodiments or examples.

[0026] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0027] In order to ensure the cooling capacity of the cooling pack, this embodiment designs a cooling auxiliary device for the core of the cooling pack to assist the inherent heat dissipation system inside the cooling pack and achieve emergency cooling of the cooling medium (coolant or air) flowing through the core of the cooling pack.

[0028] like Figure 1 As shown, the cooling pack cooling auxiliary device in this embodiment mainly includes key components such as a water storage tank 1, a water pump 2, a spray pipe 3, a water receiving tank 4, a temperature sensing module, and a control module 9.

[0029] The water storage tank 1 is used to hold cooling water. A liquid level sensor 11 can be installed at the bottom to detect the remaining amount of cooling water in the water storage tank 1 and generate a liquid level detection signal to send to the control module 9 so that when the cooling water in the water storage tank 1 is insufficient, it can remind personnel to replenish it in time.

[0030] The water pump 2 is connected to the water storage tank 1 through the inlet and outlet water pipes 21. On the one hand, it can transport the cooling water in the water storage tank 1 to the spray pipe 3, and after pressurizing the cooling water, it can spray it onto the cooling core 10 in the state of a high-pressure water column to accelerate the heat dissipation of the cooling core 10. On the other hand, it can pump the cooling water collected in the water receiving tank 4 back to the water storage tank 1 to realize the recycling of cooling water.

[0031] To meet the above design requirements, in some embodiments, the water pump 2 may specifically be a high-pressure electronic water pump with a built-in motor and flow path switching valve 22. By controlling the forward or reverse rotation of the motor and adjusting the selection direction of the flow path switching valve 22, the flow direction of the cooling water can be changed, so that the high-pressure electronic water pump 2 can work in the cooling water spray mode or the cooling water recovery mode.

[0032] Specifically, the common port of the high-pressure electronic water pump 2 can be connected to the water storage tank 1 through the inlet and outlet pipes 21, one of the selected ports of the high-pressure electronic water pump 2 can be connected to the spray pipe 3 through the outlet pipe 23, and the other selected port of the high-pressure electronic water pump 2 can be connected to the water receiving tank 4 through the return pipe 24. The high-pressure electronic water pump 2 is configured to be connected to the control module 9 through a communication cable to receive control signals from the control module 9 to determine the direction of motor rotation and the selection direction of the flow path switching valve 22.

[0033] In addition, a separate battery 7 can be configured to power the high-voltage electronic water pump 2 to meet the power requirements of the high-voltage electronic water pump 2.

[0034] In some embodiments, the spray pipe 3 can be arranged above the cooling core 10 so that the high-pressure cooling water jet sprayed through the spray pipe 3 can basically cover the entire surface of the cooling core 10, thereby accelerating the cooling speed and achieving balanced heat dissipation of the cooling core 10.

[0035] As a specific installation method for the spray pipe 3, a casing 8 can be installed around the cooling core body 10, such as... Figure 1 As shown, a housing 8 is used to enclose the cooling core 10 to prevent sprayed cooling water from splashing everywhere and polluting the environment. A fixing bracket 31 is installed on the top surface of the inner wall of the housing 8, and the fixing bracket 31 can extend downward from the top surface of the inner wall of the housing 8 to directly above the cooling core 10. A spray pipe 3 is installed on the fixing bracket 31, so that the spray pipe 3 is directly above the cooling core 10 and extends along the length or width direction of the cooling core 10, so as to expand the spray area of ​​the cooling water and prevent local overheating of the cooling core 10.

[0036] A water collection tank 4 is placed directly below the cooling core 10 to collect the cooling water flowing down from the surface of the cooling core 10 after heat exchange, so as to achieve recycling.

[0037] To achieve automatic control of the auxiliary device's operating mode, this embodiment installs a temperature sensing module on the cooling core 10. By detecting the temperature of the cooling medium entering and exiting the cooling core 10, the cooling capacity of the cooling core 10 is determined based on the temperature difference. When the cooling capacity is insufficient, the water pump 2 is activated to draw cooling water from the water storage tank 1 and deliver it to the spray pipe 3. Cooling water is sprayed onto the surface of the cooling core 10 to achieve auxiliary cooling. Once the cooling capacity of the cooling core 10 is restored, the spraying process stops, the water pump 2 is restarted to collect the cooling water collected in the water receiving tank 4, and returns it to the water storage tank 1, thus achieving the recycling of cooling water.

[0038] In some embodiments, two temperature sensors can be configured in the temperature sensing module: an inlet temperature sensor 5 for detecting the temperature of the cooling medium entering the cooling core 10, and an outlet temperature sensor 6 for detecting the temperature of the cooling medium flowing out of the cooling core 10. The temperature detection signals generated by the inlet temperature sensor 5 and the outlet temperature sensor 6 are transmitted to the control module 9 to calculate the temperature difference between the inlet and outlet of the cooling medium. The larger the temperature difference, the stronger the cooling capacity of the cooling core 10; conversely, the weaker the cooling capacity. When the temperature difference drops below a set threshold, the auxiliary cooling function needs to be activated to help the cooling core 10 quickly return to its normal heat dissipation level.

[0039] To accurately detect the temperature of the cooling medium entering and exiting the cooling core 10, the inlet temperature sensor 5 and the outlet temperature sensor 6 can be positioned diagonally opposite each other in the cooling core 10, such as... Figure 1 As shown, the inlet temperature sensor 5 is located at the lower part of the cooling core 10. It can be specifically installed at the medium inlet of the cooling core 10, or it can be installed on the surface of the cooling core 10 at any position at the same horizontal level as the medium inlet, so as to accurately measure the temperature of the cooling medium entering the cooling core 10. The outlet temperature sensor 6 is located at the upper part of the cooling core 10. It can be specifically installed at the medium outlet of the cooling core 10, or it can be installed on the surface of the cooling core 10 at any position at the same horizontal level as the medium outlet, so as to accurately measure the temperature of the cooling medium flowing out of the cooling core 10.

[0040] The configuration control module 9 automatically controls the start and stop of the water pump 2 and adjusts the working status of the water pump 2 based on the temperature signals fed back by the inlet temperature sensor 5 and the outlet temperature sensor 6, so as to realize the intelligent operation of the auxiliary device.

[0041] Industrial applicability

[0042] The cooling pack cooling auxiliary device of this embodiment is applied to construction machinery (such as excavators, road rollers, etc.) to achieve emergency cooling of the cooling pack core inside the construction machinery when the construction machinery is working in an extreme high temperature environment.

[0043] Specifically, the auxiliary device, including the engine cover 8, spray pipe 3, water tank 4, and temperature sensing module, can be installed in the equipment room where the cooling pack is located. The water tank 1 and water pump 2 can be located near the driver's cab 20 to facilitate the driver in replenishing the cooling water in the water tank 1. The control module 9 can be a control system with an instrument panel installed on the control panel inside the driver's cab 20, so that when the cooling water in the water tank 1 is insufficient, a warning message can be displayed on the instrument panel to remind the driver to replenish the cooling water in time.

[0044] After the construction machinery is started, the temperature sensing module transmits the temperature of the cooling medium entering and exiting the cooling core 10 to the control system in the cab 20 in real time. The control system calculates the temperature difference between the cooling medium entering and exiting the cooling core 10. If the temperature difference is greater than a set threshold, such as greater than 90°C, the cooling capacity of the cooling core 10 is considered normal, and there is no need to activate the cooling auxiliary device. When the temperature difference is less than the set threshold, the control system generates a control signal and sends it to the water pump 2, controlling the motor in the water pump 2 to rotate forward and adjusting the flow path switching valve 22 in the water pump 2 to connect the water tank 1 and the spray pipe 3. After the water pump 2 starts, it draws cooling water from the water tank 1 and pressurizes it to be delivered to the spray pipe 3. The water is then sprayed onto the surface of the cooling core 10 as a high-pressure water jet through the spray pipe 3 to assist in the rapid cooling of the cooling core 10 and restore its cooling capacity.

[0045] During the spraying of cooling water onto the surface of the cooling core 10, the temperature of the cooling medium entering and exiting the cooling core 10 is monitored in real time. When the temperature difference stabilizes above the set threshold, the water pump 2 is controlled to stop running, ending the auxiliary cooling process.

[0046] Afterwards, the control system generates a control signal and sends it to water pump 2, controlling the motor in water pump 2 to reverse and adjusting the flow path switching valve 22 in water pump 2 to connect the water storage tank 1 and the water receiving tank 4. After water pump 2 restarts, it pumps the cooling water collected in the water receiving tank 4 back to the water storage tank 1 to achieve recycling.

[0047] The control system uses the liquid level sensor 11 to detect the remaining cooling water in the water storage tank 1 in real time. If the spraying process lasts for a long time, resulting in insufficient cooling water in the water storage tank 1, the control system first controls the water pump 2 to end the spraying process, recovers the cooling water in the water receiving tank 4, and then restarts the spraying process.

[0048] If the coolant in the reservoir 1 is still insufficient after the coolant recovery process is completed, the control system will generate a warning message and send it to the control panel in the cab 20. The message will be displayed on the instrument panel to remind the driver to replenish the coolant in time and ensure that the cooling pack cooling auxiliary device can operate normally.

[0049] The cooling pack cooling auxiliary device of this embodiment has a simple structure and can be quickly installed and removed from existing construction machinery with minimal impact on its normal operation. By installing the cooling pack cooling auxiliary device of this embodiment on construction machinery, the machinery can operate normally and efficiently in extremely high temperatures or when the cooling capacity of the cooling pack is insufficient due to other reasons, thus avoiding the problem of reduced power output of the construction machinery.

[0050] Of course, the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
