[0021] As Figures 1 to 3 Shown in one kind of cable material conveying path cooling device, including conveying water tank 10, heat exchange plate group 20, two pairs of vertical arm 30, a pair of cross arm 40 and with two cross arm 40 one to one corresponding two fans 50. The fan 50 is preferably duct fan, and preferably the fan 50 is fixed at the width of the cross arm 40 (front and back) central position. Figure 1

[0022] ​The wall of the vertical arm 30 is formed with a cavity extending in vertical direction, and the wall of the horizontal arm 40 is formed with a horizontal cavity. Two horizontal arms 40 are respectively matched with a pair of vertical arms 30. The horizontal cavity of the horizontal arm 40 and the cavity of the pair of vertical arms 30 form a reverse U-shaped flow channel structure.

[0023] The heat exchange plate group 20 is fixed in the cavity of the conveying water tank 10, and includes a front side plate group 21 and a rear side plate group 22 arranged oppositely. The front side plate group 21 and the rear side plate group 22 each include a plurality of (two in the figure) heat exchange plates arranged alternately in vertical direction. The plate body of the heat exchange plate is formed with a fluid passage extending in left-right direction.

[0024] The side wall of the conveying water tank 10 is provided with an air inlet 23 connected with the fluid passage in the heat exchange plate.

[0025] The vertical arm 30 is fixed on the side wall of the conveying water tank 10, and two pairs of vertical arms 30 are respectively arranged at the left end and the right end of the heat exchange plate group 20, and are respectively connected with the fluid passage of the heat exchange plate arranged at the same side. That is, the two vertical arms 30 in the left pair of vertical arms 30 are respectively matched with the left end of the front side plate group 21 and the left end of the rear side plate group 22, and can form a connected cavity structure. The two vertical arms 30 in the right pair of vertical arms 30 are respectively matched with the right end of the front side plate group 21 and the right end of the rear side plate group 22, and can also form a connected cavity structure.

[0026] The two horizontal arms 40 are respectively fixed at the upper end of the left pair of vertical arms 30 and the upper end of the right pair of vertical arms 30, forming a reverse U-shaped frame structure. After the two horizontal arms 40 are respectively connected with the two vertical arms 30 matched therewith, the fluid passage in the front side plate group 21 and the fluid passage in the rear side plate group 22 can be connected.

[0027] The fan 50 is fixedly assembled on the horizontal arm 40 and can be connected with the horizontal cavity of the horizontal arm 40. The flange part 41 for assembling the fan 50 is arranged on the horizontal arm 40.

[0028] When the fan 50 is activated, it draws in ambient cold air from the front and rear sides of the water tank 10 through the air inlet 23. This air enters the fluid channels of the front plate assembly 21 and the rear plate assembly 22, and flows through the two vertical arms 30 on the front and rear sides, respectively, into the left and right horizontal arms 40, and is finally discharged upwards to the outside by the fan 50. This technical solution utilizes circulating air to cool the cooling water in the water tank 10, increasing the heat exchange rate between the cooling water and the outside environment, thus maintaining the cooling water in the water tank 10 within a more reasonable (relatively lower) temperature range. This technical solution not only reduces the amount of cooling water used but also reduces evaporation loss, resulting in water conservation. Furthermore, it reduces the footprint of the entire cooling device.

[0029] Therefore, in the technical solution of this application, cold air can be introduced into the fluid channels of each heat exchange plate in the front plate assembly 21 and the fluid channels of each heat exchange plate in the rear plate assembly 22 through each air inlet 23 to cool the water contained in the conveying water tank 10, so that the water in the conveying water tank 10 can maintain a good cooling temperature. It should be noted that the conveying water tank 10 still has a circulation relationship with the external circulating water tank. By setting up an air-cooling system, the total amount of cooling water required for the entire cooling process can be reduced compared to existing cooling devices, and it also helps to significantly reduce the volume and floor space of the external circulating water tank.

[0030] To allow the heat exchange plate assembly 20 to have a longer extension (along...) Figure 1 (The length in the left-right direction of the view shown) Preferably, a baffle is provided in the fluid channel of each heat exchange plate at a central position along the length to divide the fluid channel in the heat exchange plate into left and right sections. Correspondingly, air inlets 23 are provided on the water delivery tank 10, communicating with the (two sections) of fluid channels located on both sides of the baffle (left and right). According to the aforementioned limited scheme, as Figure 1 , Figure 2As shown, one air inlet 23 is arranged on the left and right sides of the partition plate respectively, corresponding to the fluid channel on each heat exchange plate. Therefore, in the illustrated scheme, four air inlets 23 are arranged on the front side groove wall of the conveying water tank 10, corresponding to the front side plate group 21, and four air inlets 23 are arranged on the rear side groove wall of the conveying water tank 10, corresponding to the rear side plate group 22. Based on the foregoing scheme, the length extension size of each heat exchange plate in the heat exchange plate group 20 can be significantly extended under the premise of ensuring the cooling effect of the cooling air (on the water in the conveying water tank 10), which helps to reduce the number of cooling devices in the cable material conveying path arranged in the length extension direction of the conveying water tank 10. It should be emphasized that the cooling devices in multiple cable material conveying paths can share one circulating water tank.

[0031] As shown in the drawings, Figure 1 As shown, four arc-shaped plates 24 are arranged in the fluid channel of each heat exchange plate and distributed in the width direction (the front-rear direction shown in the drawings), and the arch surfaces of the arc-shaped plates 24 are all directed to the side away from the inner wall of the conveying water tank 10, i.e., the arch surfaces of the arc-shaped plates 24 are directed to the free end side of the heat exchange plate, close to the central position of the groove width of the conveying water tank 10. The arrangement of multiple arc-shaped plates 24 in the fluid channel of the heat exchange plate can promote the uniform distribution of cooling air introduced into the heat exchange plate in the entire width direction (the front-rear direction shown in the drawings) of the heat exchange plate, improve the uniform distribution degree of cooling air on the heat exchange plate, and make the heat exchange plate fully exert the heat dissipation / heat exchange efficiency.

[0032] As shown in the drawings, Figure 3 As shown, the width (the left-right dimension shown in the drawings) of each heat exchange plate in the front side plate group 21 and the width of each heat exchange plate in the rear side plate group 22 are arranged in a distribution change state that the width of the heat exchange plate located at the lower part is greater than the width of the heat exchange plate located at the upper part. In other words, the width change condition between each heat exchange plate in the front side plate group 21 is a distribution change state that the width of the heat exchange plate located at the lower part is greater than the width of the heat exchange plate located at the upper part; the width change condition between each heat exchange plate in the rear side plate group 22 is a distribution change state that the width of the heat exchange plate located at the lower part is greater than the width of the heat exchange plate located at the upper part. At the same time, a large vertical spacing is formed between the heat exchange plate located at the lowermost layer and the groove bottom wall plate 11 of the conveying water tank 10, generally between 5 cm and 15 cm. Preferably, the heat exchange plate can be arranged obliquely and inclined downward from the inner wall side of the conveying water tank 10 to the central position of the groove width of the conveying water tank 10. The foregoing scheme can relatively increase the overall heat exchange area of the heat exchange plate without affecting the conveying of the cable material, and can improve the heat exchange efficiency of the heat exchange plate group 20.

[0033] As shown in the drawings, Figure 1The arrows shown: start the fan 50 set on the left side of the cross arm 40, can make the front and rear of the conveying water tank 10 air, respectively through the air inlet 23 set on the two side tank walls, flow into the left half of the fluid channel of each heat exchange plate in the front plate group 21, and after flowing through the width direction of the heat exchange plate, flow to the horizontal cavity of the cross arm 40 set on the left side through the cavity in the front and rear two vertical arms 30, and finally from the air outlet of the fan 50 to the outside; at the same time, start the fan 50 set on the right side of the cross arm 40, can make the front and rear of the conveying water tank 10 air, respectively through the air inlet 23 set on the two side tank walls, flow into the right half of the fluid channel of each heat exchange plate in the front plate group 21, and after flowing through the width direction of the heat exchange plate, flow to the horizontal cavity of the cross arm 40 set on the right side through the cavity in the front and rear two vertical arms 30, and finally from the air outlet of the fan 50 to the outside.

The present application can be improved in many aspects without departing from the general idea, and those skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application.
