[0014] The following further describes the utility model in detail with reference to the drawings and specific embodiments. According to the following description, the advantages and features of the utility model will be clearer.

[0015] As Figure 1 shown, this embodiment specifically provides a geotextile cooling device with multi-channel uniform air flow, including a fan 1, a heat exchanger 2, an upper air chamber 3, a lower air chamber 4, an air distribution system and a clamping device 9. The air distribution system includes a guide plate 5, a static pressure box 6 and an air outlet plate 8. The fan 1 is installed on one side of the device body, and the heat exchanger 2 is located on one side of the upper air chamber 3 and the lower air chamber 4, on the same side as the fan 1. Both ends of the guide plate 5 are respectively connected to the heat exchanger 2 and the static pressure box 6. The static pressure boxes 6 are symmetrically distributed on the lower side of the upper air chamber and the upper side of the lower air chamber. The static pressure box air inlet 7 is located in the air duct separated by the guide plate 5. The clamping device 9 is in the middle of the upper and lower static pressure boxes and is fixed on the left and right sides of the device body, clamping the geotextile 10 and moving forward.

[0016] The heat exchanger of the utility model adopts a plate heat exchanger, which has a large heat exchange area; the cooling medium is cooling water, which has good heat transfer performance and fluidity, and can increase the heat exchange efficiency.

[0017] A temperature control sensor is provided at the air outlet of the heat exchanger of the utility model, which can monitor and regulate the temperature of the cooling air and accelerate the cooling efficiency.

[0018] The guide plate of the utility model divides the air chamber into several non-communicating air ducts, and the corner of the guide plate is 90°, which can reduce the sharp turn of the air flow, reduce the resistance of the air flow during the turning process, and make the air flow flow more smoothly.

[0019] The static pressure box of the utility model is communicated with the air chamber, and the air inlets are evenly distributed in the air duct to ensure uniform air inlet of the static pressure box.

[0020] The surface of the air outlet plate of the present utility model has evenly arranged air outlet holes, which can evenly discharge cooling air to avoid uneven cooling caused by air flow concentration or uneven distribution.

[0021] The clamping device of the present utility model adopts a needle plate for clamping, which is convenient to operate and can evenly provide clamping force to prevent the geotextile from deforming. At the same time, it promotes the uniform flow of cooling air on the geotextile, thereby improving the cooling efficiency and effect.

[0022] The working principle of the present utility model is as follows: First, set the required temperature of the cooling air and start the cooling and shaping device; then, the fan inhales fresh air in the environment into the device, and the air enters the heat exchanger in the upper and lower air chambers through the air inlet. Through the heat exchange effect, the heat in the air is transferred to the cooling water, thereby realizing the cooling of the air flow. The cooled air flow is blown out through the air outlet of the heat exchanger, and the guide plate guides the blown cooling air flow to independent air ducts respectively. Subsequently, the cooling air flow enters the static pressure box through the air inlet of the inner static pressure box of the air duct. The flow velocity of the air flow entering the static pressure box decreases, and the dynamic pressure is converted into static pressure. Finally, the static pressure air flow blows the cooling air towards the geotextile through the evenly arranged blowing holes on the air outlet plate. The two sides of the geotextile are clamped by needle plates, and the needle plates are fixed on the needle cheek chain to clamp the geotextile and move forward, realizing the counter blowing cooling of the upper and lower surfaces of the geotextile.
