Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, specifically a high-efficiency and energy-saving heat dissipation structure for a hydraulic station. Background Technology

[0002] A hydraulic power unit is a hydraulic source device or a hydraulic device including control valves, consisting of a hydraulic pump, a drive motor, an oil tank, a directional valve, a throttle valve, and a relief valve.

[0003] Existing technologies may rely excessively on external power equipment to drive the flow of coolant, increasing energy consumption and equipment costs. At the same time, if the power equipment fails, the coolant circulation will be affected, leading to the failure of the heat dissipation system. To address this, we propose a high-efficiency and energy-saving heat dissipation structure for hydraulic power stations. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency and energy-saving heat dissipation structure for hydraulic stations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency and energy-saving hydraulic station heat dissipation structure, including a liquid storage tank, a heat dissipation box connected to the upper end of the liquid storage tank, six flow dividers connected to the inner wall of the liquid storage tank, a manifold connected between each flow divider, and both ends of the manifold connected to the inside of the flow divider respectively. A second connecting pipe is connected to the left side of the liquid storage tank, and both ends of the second connecting pipe are connected to the inside of the liquid storage tank and the heat dissipation box respectively. A one-way valve is connected to the right side of the liquid storage tank, a first connecting pipe is connected to the side of the one-way valve, and both ends of the first connecting pipe are connected to the one-way valve and the inside of the heat dissipation box respectively. Heat dissipation fins are connected to the upper end of the heat dissipation box. A fixing frame is connected to the inner wall of the one-way valve, a limit rod is connected to the side of the fixing frame, a valve block is slidably connected to the surface of the limit rod, and a spring is sleeved on the surface of the limit rod.

[0006] As a further embodiment of this utility model: the right side of the liquid storage tank is connected to an inlet pipe, one end of which penetrates the inner wall of the liquid storage tank and is connected to one of the diversion channels.

[0007] As a further embodiment of this utility model: a drain pipe is connected to the left side of the liquid storage tank, and one end of the drain pipe penetrates the inner wall of the liquid storage tank and is connected to one of the diversion plates.

[0008] As a further embodiment of this utility model: one end of the spring is connected to the side of the fixing frame.

[0009] As a further embodiment of this utility model: the other end of the spring is connected to the side of the valve block.

[0010] As a further embodiment of this utility model: the side of the valve block matches the inner wall of the one-way valve.

[0011] As a further embodiment of this utility model: one end of the one-way valve is connected to the inside of the liquid storage tank.

[0012] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0013] 1. This utility model utilizes the temperature difference generated after heat exchange between high-temperature hydraulic oil and coolant to enable natural convection of coolant. Natural convection drives the coolant to circulate between the reservoir and the heat sink, eliminating the need for additional external power equipment and avoiding dependence on external power equipment, thereby reducing energy consumption. Compared with the prior art, it saves the electrical energy and other energy required to drive the coolant flow, achieving the goal of energy saving.

[0014] 2. This utility model uses the combination of a flow divider and a manifold to ensure that the hydraulic oil is evenly distributed in the reservoir, allowing it to fully contact and exchange heat with the coolant. This increases the heat exchange area and improves the heat exchange efficiency. The heat dissipation fins on the top of the heat dissipation tank further increase the heat dissipation area and accelerate the cooling speed of the coolant, enabling the coolant to cool down quickly. This achieves efficient heat dissipation of the hydraulic oil, ensuring that the hydraulic oil maintains a suitable temperature during operation and maintaining stable system operation.

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0024] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Please see the appendix Figure 1 - Appendix Figure 6 This utility model discloses a high-efficiency and energy-saving hydraulic station heat dissipation structure, including a liquid storage tank 1. A heat dissipation box 5 is connected to the upper surface of the liquid storage tank 1. Six flow dividers 8 are connected to the inner wall of the liquid storage tank 1, and a manifold 9 is connected between each flow divider 8. Both ends of the manifold 9 are connected to the interior of the flow divider 8. A second connecting pipe 10 is connected to the left side of the liquid storage tank 1, and both ends of the second connecting pipe 10 are connected to the interior of both the liquid storage tank 1 and the heat dissipation box 5. A one-way valve 7 is connected to the right side of the liquid storage tank 1, and a first connecting pipe 4 is connected to the side of the one-way valve 7. The two ends of 4 are respectively connected to the one-way valve 7 and the interior of the heat sink 5. The upper end of the heat sink 5 is connected to the heat sink fins 6. The inner wall of the one-way valve 7 is connected to the fixing bracket 14. The side of the fixing bracket 14 is connected to the limit rod 12. The surface of the limit rod 12 is slidably connected to the valve block 11. The surface of the limit rod 12 is sleeved with a spring 13. One end of the spring 13 is connected to the side of the fixing bracket 14. The other end of the spring 13 is connected to the side of the valve block 11. The side of the valve block 11 matches the inner wall of the one-way valve 7. One end of the one-way valve 7 is connected to the interior of the liquid storage tank 1.

[0026] In Example 1, an inlet pipe 2 is connected to the right side of the liquid storage tank 1. One end of the inlet pipe 2 penetrates the inner wall of the liquid storage tank 1 and is connected to one of the diversion plates 8.

[0027] Specifically, the inlet pipe 2 is the channel for hydraulic oil to enter the reservoir 1. One end is connected to an external hydraulic oil source, and the other end passes through the inner wall of the reservoir 1 and connects to one of the diverter plates 8, guiding the hydraulic oil into the diverter plate 8 and then dispersing it into the interior of multiple diverter plates 8.

[0028] In Example 2, a drain pipe 3 is connected to the left side of the liquid storage tank 1, and one end of the drain pipe 3 penetrates the inner wall of the liquid storage tank 1 and is connected to one of the diversion plates 8.

[0029] Specifically, the drain pipe 3 is used to drain the hydraulic oil in the reservoir 1. The hydraulic oil undergoes heat exchange in the distributor plate 8 and then flows out through the drain pipe 3.

[0030] Working principle:

[0031] First, hydraulic oil flows into the distributor plate 8 through the inlet pipe 2. The distributor plate 8 evenly disperses the hydraulic oil. At this time, the high-temperature hydraulic oil comes into full contact with the coolant in the reservoir 1, and heat transfer occurs. Due to the temperature difference, the hydraulic oil transfers heat to the coolant, causing its own temperature to decrease. The coolant absorbs heat and its temperature rises, creating a temperature difference in the reservoir 1, which in turn causes the coolant to flow. The coolant undergoes convection due to the temperature difference, and the hot coolant flows into the radiator 5 through the second connecting pipe 10. The radiator fins 6 on the radiator 5 increase the heat dissipation area, accelerating the dissipation of coolant into the surrounding environment. The heat causes the coolant temperature to drop. After cooling, the coolant flows back to the reservoir 1 through the first connecting pipe 4 under the action of the pressure difference and the one-way valve 7. The one-way valve 7 ensures that the coolant can only flow in one direction to prevent backflow and ensure stable circulation of the coolant. The coolant flowing back to the reservoir 1 exchanges heat with the high-temperature hydraulic oil that newly flows into the distributor plate 8 again, repeating the above heat dissipation process. High-temperature hydraulic oil continuously flows in, and the coolant continues to circulate, continuously carrying away the heat of the hydraulic oil, thereby maintaining the hydraulic oil within a suitable temperature range and ensuring the stable operation of the hydraulic station. At this point, the entire working process ends.
