Description

TECHNICAL FIELD

[0001] The utility model relates to bridge engineering cooling technical field, concretely relates to a natural cooling device for equipment circulating liquid cooling in high and cold region. BACKGROUND

[0002] The statements herein only provide background technology related to the utility model and do not necessarily constitute prior art.

[0003] The climate of Qinghai-Tibet Plateau and Tianshan region permafrost zone is bad, and the ice freezing period is about 8 months a year, and the average annual temperature is -2 DEG C to 6 DEG C, and the construction of cast-in-place concrete in high mountain permafrost region means that the mixing, transportation and pouring of concrete can only be carried out at low temperature, and for concrete, the strength and curing temperature are directly related, and if the curing temperature is not suitable, the strength of concrete will rise slowly, and even cannot reach the design strength, and then seriously disturb the frozen soil, and affect the freezing of the frozen soil around the pile. Therefore, for the pile foundation engineering in cold region, it is of great significance to study how to improve the cooling efficiency of pile foundation.

[0004] For the concrete bored pile in permafrost region, the natural freezing method is generally used in the actual engineering at the present stage, and the negative temperature environment around the pile foundation is the curing temperature of the pile foundation concrete. A large amount of hydration heat released in the hydration reaction process of the pile foundation concrete will cause great thermal disturbance to the frozen soil around the pile, cause the frozen soil around the pile to melt, cause problems such as hole expansion and water accumulation, and affect the freezing time of the frozen soil around the pile. In the permafrost region, the bearing capacity of the pile foundation is mostly from the freezing force of the frozen soil around the pile, and the freezing time of the frozen soil around the pile has important influence on the formation of the bearing capacity of the pile foundation and the subsequent construction time. Only by effectively controlling the temperature of the hydration process of the pile foundation and making it react at negative temperature, the stability of the frozen soil around the pile can be ensured.

[0005] As the key substance for controlling the temperature of the hydration process of the pile foundation, the circulating liquid is transported to the inside of the pile foundation through the pipeline system, and absorbs the heat in the soil through heat exchange with the pile body and the surrounding soil. Therefore, in order to ensure the stability of the frozen soil around the pile, the key is to realize the effective cooling of the circulating liquid. When the equipment circulating liquid is cooled, the inventor finds that the existing cooling device generally has one or more problems of high energy consumption, high cost or poor cooling efficiency.

[0007] The cooling tank is a long rectangular cavity box body with an upper opening, and a plurality of heat-conducting partitions are arranged in the cavity box body of the cooling tank.

[0008] Along the length direction of the cooling tank, liquid inlet pipe and liquid outlet pipe are arranged at the front and back ends respectively; circulating liquid flows into the cooling tank through the liquid inlet pipe and flows out through the liquid outlet pipe.

[0009] As a further technical solution, the cooling tank is arranged with an inclination angle relative to the horizontal direction.

[0010] As a further technical solution, the liquid inlet pipe and the liquid outlet pipe are respectively located near the corners of the front and back ends of the cooling tank.

[0021] Figure 1 A structure schematic view of the natural cooling device for circulating liquid of equipment in high-cold region in the first embodiment of the present application.

[0022] In the figure, 1 is a filter control speed net; 2 is a liquid inlet pipe; 3 is a heat-conducting partition plate; 4 is a liquid outlet pipe; and 5 is a cooling tank.

[0023] Embodiment I

[0024] The specific implementation manner of the present embodiment will be described below in combination with the accompanying drawings. Figure 1

[0025] As shown in the figure, the present embodiment provides a natural cooling device for circulating liquid of equipment in high-cold region, which comprises a cooling tank 5. Figure 1 The cooling tank 5 is a long rectangular cavity box body with an open upper part, and a plurality of heat-conducting partition plates 3 are arranged in the cavity box body of the cooling tank 5.

[0026] Along the length direction of the cooling tank 5, a liquid inlet pipe 2 and a liquid outlet pipe 4 are arranged at the front and rear ends of the cooling tank 5 respectively; the circulating liquid flows into the cooling tank 5 through the liquid inlet pipe 2 and flows out through the liquid outlet pipe 4.

[0027] The open design of the cooling tank enables the circulating liquid to be in large-area contact with air, thereby quickly performing heat exchange. Therefore, the cooling device designed in the present application can effectively improve the cooling rate of the circulating liquid. In addition, the cooling device performs heat exchange with the aid of air and does not need to use auxiliary equipment to perform secondary cooling of the circulating liquid. Taking the electrolytic device commonly used in the prior art as an example, in the electrolysis process, when the electric current passes through the electrolyte solution, the electric energy is converted into chemical energy and is accompanied by heat absorption and release, and by giving special conditions, the cooling of the circulating liquid is realized. The whole process consumes a large amount of electric energy, compared with the present application, the cooling device realizes high-speed cooling and also ensures low power consumption.

[0028] As a further technical solution, the cooling tank 5 is arranged at an inclination angle with respect to the horizontal direction, which can make the circulating liquid flow more smoothly. Specifically, the cooling tank foundation is rammed at a certain angle, and the cooling tank 5 is placed on the foundation to realize the inclination angle with respect to the horizontal direction.

[0029] ​As a further technical solution, the liquid inlet pipe 2 and the liquid outlet pipe 4 are located at the near corners of the front and rear ends of the cooling tank 5. Specifically, the liquid inlet pipe 2 is located at the near corner of the high inclination angle of the cooling tank 5, and the liquid outlet pipe 4 is located at the near corner of the low inclination angle of the cooling tank 5.

[0030] The position design of the liquid inlet pipe 2 and the liquid outlet pipe 4 can maximize the effect of making the circulation liquid flow more smoothly through the inclination angle.

[0031] As a further technical solution, a plurality of heat-conducting partitions 3 are arranged along the length direction of the cooling tank 5; at the same time, the heat-conducting partitions 3 are placed transversely along the width direction of the cooling tank 5 and abut against the inner vertical surface of the cooling tank 5; when placed transversely, the width of the heat-conducting partition is consistent with the height of the cooling tank.

[0032] When the circulation liquid flows into the cooling tank 5 through the liquid inlet pipe 2, the plurality of heat-conducting partitions 3 can effectively increase the flow time of the circulation liquid in the cooling tank and increase the contact area between the circulation liquid and the heat-conducting partitions, thereby further improving the cooling efficiency of the circulation liquid.

[0033] As a further technical solution, the heat-conducting partitions 3 are made of aluminum material and are in the shape of a cuboid. Based on this design, the heat-conducting property of the heat-conducting partitions 3 can be ensured to be good and the quality is small.

[0034] As a further technical solution, one end of the heat-conducting partition 3 is provided with a filtering speed control net 1, and the filtering speed control net 1 is arranged in an "S" shape. Specifically, the end of the filtering speed control net 1 on the group of heat-conducting partitions 3 closest to the liquid inlet pipe 2 abuts against the end of the cooling tank 5 farthest from the liquid inlet pipe 2, and the filtering speed control nets 1 on the remaining groups of heat-conducting partitions 3 are arranged in an "S" shape.

[0035] The "S" shape of the filtering speed control net 1 in the heat-conducting partition 3 of the utility model can ensure that the circulation liquid needs to flow through all the heat-conducting partitions 3 after entering the cooling tank, thereby further ensuring the flow time of the circulation liquid in the cooling tank.

[0036] As a further technical solution, the aperture size of the filtering speed control net 1 and the angle of the inclination angle are adjustable. Specifically, the filtering speed control net 1 is a double-layer structure including a fixed layer and a movable layer. When the apertures of the fixed layer and the movable layer completely coincide, the liquid guide is the fastest, and the movable layer is pushed. When the apertures completely misalign, the effective aperture is the smallest and the liquid flow rate is the smallest. By adjusting the aperture size of the filtering speed control net 1 and the inclination angle of the cooling tank 5, the circulation liquid flow rate can be controlled, thereby achieving the purpose of controllable cooling and heat dissipation efficiency; at the same time, it also has the effect of filtering impurities and keeping the circulation liquid pure.

[0037] The cooling device can realize effective cooling of the circulating liquid through the cooling groove 5, the heat-conducting partition plate 3 and the filtering speed control net 1, and can meet the needs of low energy consumption, low cost and high cooling efficiency of the cooling device in the pile foundation construction process.

[0038] Although the specific embodiments of the utility model have been described in combination with the drawings, it is not a limitation on the protection scope of the utility model, and the skilled person in the art should understand that various modifications or changes made by the skilled person in the art on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
