Based on this, the present application intends to provide a solution to the above technical problem, the details of which will be explained in the following embodiments.
The utility model discloses a multi-flow heat exchange plate structure for a closed cooling tower, please refer to fig. 1 to 3 together, fig. 1 is a first structural schematic diagram of the multi-flow heat exchange plate structure for the closed cooling tower provided by the utility model; FIG. 2 is a second structural diagram of a multi-flow heat exchange plate structure for a closed cooling tower according to the present invention; fig. 3 is a working principle diagram of a multi-flow heat exchange plate structure for a closed cooling tower provided by the utility model. The multi-flow heat exchange plate structure for the closed cooling tower comprises two heat exchange plates which are attached, wherein the two heat exchange plates form a group, and the two heat exchange plates have the same structure and are symmetrically attached; wherein the heat exchanger plate comprises: plate body 100, liquid inlet hole 110, liquid outlet hole 120 and flow channel 130; specifically, the plate body 100 is rectangular, for example, rectangular; optionally, the plate body is made of a flexible material, the liquid inlet hole 110 and the liquid outlet hole 120 are disposed on the plate body 100, the liquid inlet hole 110 is used for entering liquid, such as a medium to be cooled (hereinafter, this is taken as an example), and the liquid outlet hole 120 is used for discharging the liquid.
The plurality of flow channels 130 are disposed on the plate body 100 at intervals, for example, each flow channel 130 is recessed at a predetermined distance from each other and disposed on the plate body 100, in practical use, the flow channels 130 can be formed by pressing the plate body 100 through a mold, the distribution of the flow channels 130 can be set according to practical requirements, for example, the flow channels 130 are distributed on the plate body 100 according to an "S" shape or distributed according to an "M" shape, the specific distribution condition is not limited herein, and of course, the purpose is to increase the flow path of the medium to be cooled, so that the disturbance is greater when the medium to be cooled flows, and the heat exchange is more sufficient. As shown in fig. 3, the flow channel 130 of any one of the heat exchanger plates is communicated with the flow channel 130 of another one of the heat exchanger plates to form a flow channel 200 (indicated by arrows in fig. 3), and the liquid outlet 110 and the liquid inlet 120 are respectively communicated with the flow channel 200.
Further, the flow channels 130 adjacent to the liquid inlet hole 110 and the liquid outlet hole 120 are respectively communicated with the liquid inlet hole 110 and the liquid outlet hole 120, wherein the flow channels 130 communicated with the liquid inlet hole 110 flow into the medium to be cooled through the liquid inlet hole 110, and the flow channels 130 communicated with the liquid outlet hole 120 flow out of the medium to be cooled through the liquid outlet hole 120.
In a specific embodiment, the flow channels 130 in the two heat exchange plates are communicated; therefore, flow channels of a medium to be cooled are formed, for example, the flow channels 130 on the plates are distributed according to an "S" shape, when two heat exchange plates are attached to each other, the mouth of the flow channel 130 in any one heat exchange plate is opposite to and communicated with the mouth of the flow channel 130 on the other heat exchange plate, so that the medium to be cooled is in a neglected moving state when flowing between the flow channels 130 (as shown in fig. 3), thereby ensuring that the medium to be cooled generates disturbance when flowing in the flow channels, and accelerating the loss of heat of the medium to be cooled (the principle is similar that the medium to be cooled is cooled faster when hot water is stirred).
It is worth to be noted that, a premise is needed when two heat exchange plates are attached together to achieve communication of the flow channels 130, as shown in fig. 3, the flow channels 130 on two heat exchange plates need to be arranged in a staggered manner, and a single flow channel 130 on any one heat exchange plate is communicated with two adjacent flow channels 130 on another heat exchange plate, so that the flow channels 130 on two heat exchange plates can be communicated with each other; further, after the flow channels 130 on the two heat exchange plates are communicated with each other, a flow channel 200 capable of flowing is formed, at this time, the medium to be cooled is injected from the liquid inlet hole 110, and an arrow in the figure shows a movement track of the medium to be cooled flowing along the flow channel 200; due to the special structure that the plurality of flow channels 130 are arranged on the plate body at intervals, when the medium to be cooled flows in the flow channel 200, the medium to be cooled needs to flow through all the flow grooves 130 on the two heat exchange plates, so that the flow path of the medium to be cooled is actually quite long, the heat exchange of the medium to be cooled can be more sufficient due to the long flow path, and the medium to be cooled can be rapidly subjected to heat exchange due to the fact that the long flow path is combined with the flow path and a disturbance state can occur simultaneously.
Meanwhile, under the condition of a large number of flow channels, the flow channel 130 can be designed to be narrow, and if the flow channel 200 formed by the flow channel 130 is narrow, the flow area of the medium to be cooled is small, so that the flow velocity of the medium to be cooled is increased, the heat of the medium to be cooled is accelerated to be lost along with the increase of the flow velocity, and the heat exchange of the medium to be cooled is further accelerated.
As a further alternative, the flow channel 200 is a serpentine flow channel, and the flow channels 130 are arranged side by side along the extending direction of the serpentine flow channel; specifically, a plurality of rows of flow channels 130 in the serpentine flow channel are distributed along the width direction of the plate body 100, as shown in fig. 1, the upper and lower directions of the plate body 100 are the width direction thereof, four rows of flow channels 130 are arranged from top to bottom, and each row of flow channels 130 is distributed along the length direction of the plate body 100; in the specific embodiment, when the number of the flow channels 130 is four, the liquid inlet hole 110 is communicated with the first flow channel 130 in the first row, and correspondingly, the liquid outlet hole 120 is communicated with the last flow channel 130 in the fourth row; therefore, the flow channels 130 are uniformly distributed on the plate body 100 in a plurality of rows, so that the area of the plate body 100 can be maximally utilized, the flow path of the medium to be cooled is longer, and the heat exchange is more sufficient. It should be understood that the number of rows for the flow channels 130 is merely exemplary, and may be multiple rows in practical use, such as 6 rows, 8 rows, and so on.
In some preferred embodiments, in order to maximize the realization of multiple processes, the liquid inlet holes 110 and the liquid outlet holes 120 are symmetrically arranged along the width direction of the plate body 100 or the liquid inlet holes 110 and the liquid outlet holes 120 are symmetrically arranged along the length direction of the plate body. When the liquid inlet hole 110 and the liquid outlet hole 120 are symmetrically arranged in the width direction of the plate body, that is, the liquid inlet hole 110 and the liquid outlet hole 120 are both located on the shorter side edge of the plate body 100, with continuing to combine with fig. 1, the vertical direction of the plate body 100 is the width direction thereof, the liquid inlet hole 110 is arranged at the upper right corner of the plate body 100, and the liquid outlet hole 120 is arranged at the lower right corner of the plate body 100; when the liquid inlet 110 and the liquid outlet 120 are symmetrically disposed in the length direction of the plate body, the plate body 100 may be continuously combined with fig. 2, the up-down direction of the plate body 100 is the width direction, the liquid inlet 110 is disposed at the upper right corner of the plate body 100, and the liquid outlet 120 is disposed at the lower left corner of the plate body 100.
Further, for coordinating the positions of the liquid inlet hole 110 and the liquid outlet hole 120, when the liquid inlet hole 110 and the liquid outlet hole 120 are symmetrically disposed along the width direction of the plate body 100, the number of rows of the flow channel 130 is an even number, and when the liquid inlet hole 110 and the liquid outlet hole 120 are symmetrically disposed along the length direction of the plate body, the number of rows of the flow channel 130 is an odd number. Of course, such an arrangement is not meaningless, because the number of the flow channels 130 can be obviously increased by the even rows compared with the number of the flow channels 130 of the odd rows, and the increase of the number of the flow channels 130 means that the distance that the medium to be cooled can flow in the flow channels 130 is more, the flow path is longer, and therefore, the heat dissipation effect is better, and the heat exchange is more sufficient. It should be understood that the even or odd rows for the flow channels should be set according to actual requirements.
Specifically, the flow channels 130 on one end of each two rows away from the liquid inlet 110 or the liquid outlet 120 are communicated with each other; the flow channels 130 positioned between the liquid inlet holes 110 and the liquid outlet holes 120 in every two rows are communicated; referring to fig. 1, the liquid inlet hole 110 is used as a reference, the liquid inlet hole 110 is connected to the rightmost flow channel 130 in the first row of flow channels 130, and the leftmost flow channel 130 in the first row is communicated with the leftmost flow channel 130 in the second row, so that the purpose of the design is that when two heat exchange plates are attached to each other, the medium to be cooled which previously flows in the first row of flow channels 130 needs to be diverted to the second flow channel 130, and therefore, the structure can facilitate the diversion of the medium to be cooled. Similarly, the leftmost flow channel 130 in the third row is communicated with the leftmost flow channel 130 in the fourth row, so as to divert the medium to be cooled flowing in the third row flow channel 130 to the fourth flow channel 130.
Correspondingly, the rightmost flow channels 130 in the second row and the rightmost flow channels 130 in the third row, which are located between the liquid inlet hole 110 and the liquid outlet hole 120, are communicated, and the same is to divert the medium to be cooled flowing in the flow channels 130 in the second row to the flow channels 130 in the third row, and the principle is similar to that described above, and is not described herein again.
More specifically, the side wall of the flow channel 130 is arc-shaped, so that smooth flow of the medium to be cooled can be ensured, and stagnation in the flow channel 130 is avoided; further, the bottom surface of the flow channel 130 is a plane, because in practical use, a plurality of multi-flow heat exchange plate structures for the closed cooling tower need to be assembled together for heat exchange of a medium to be cooled, and the bottom surface of the flow channel 130 is set to be a plane, and the outer part of the flow channel is also a plane, so that the bottom surface of the flow channel 130 which is in a plane shape can be smoothly contacted when two multi-flow heat exchange plate structures for the closed cooling tower are assembled, and the dislocation is not easy. Optionally, the bottom surface of the flow channel 130 is rectangular. Of course, the above description of the shape of each part of the flow channel is only an example, and the specific shape of the flow channel can be set according to actual requirements.
Furthermore, the flow channel 200 includes a plurality of rows of flow channels, and the row-to-row spacing between two adjacent rows of flow channels 130 is equal, that is, the row spacing between two rows of flow channels 130 is consistent, so that it can be ensured that the medium to be cooled does not flow out of a certain row of flow channels 130 when flowing through the certain row of flow channels 130; optionally, the adjacent flow channels 130 in each row of flow channels 130 have the same spacing distance, so that the area of the plate body 100 is maximally utilized, and the flow channels 130 are conveniently machined.
In other preferred embodiments, a sealing ring 150 is provided on the outer side of the plate body 100 to match the shape of the plate body 100, so as to prevent the leakage of the medium to be cooled from the flow channel 130. Further, the distance between the rows of the two adjacent rows of the flow channels 130 forms a separation strip 140, specifically, when two heat exchange plates are attached together, the flow channels 130 on the two plates are in a mutually communicated state, and the other parts are attached together, that is, the plate body 100 between the two rows of the flow channels 130 serves as the separation strip 140, and the separation strip 140 is used for preventing the medium to be cooled from leaking when the two heat exchange plates are attached together.
It is worth mentioning that the multi-flow heat exchange plate structure for the closed cooling tower has the characteristic of being detachable, does not need to weld the heat exchange plates, saves a large amount of welding materials, reduces the skill requirements on production personnel, and prolongs the service life of products. Benefit from simultaneously increasing the dismantled state between board and the board, increased the flexible volume in space to the material that combines to heat transfer plate selects flexible material, makes it possess anti-icing function.

in the first aspect, two heat exchange plates are attached together in a staggered manner, so that the flow channels 130 of the two heat exchange plates are communicated with each other; after the flow channels 130 on the two heat exchange plates are communicated with each other, a flow channel 200 capable of flowing is formed, at this time, the medium to be cooled is injected from the liquid inlet hole 110, and the medium to be cooled is in a fluctuating motion state when flowing in the flow channel 200 formed by the flow channels 130, so that the medium to be cooled generates disturbance when flowing in the flow channel, the heat loss of the medium to be cooled is accelerated, and the heat exchange is accelerated.
In the second aspect, due to the special structure that the plurality of flow channels 130 are arranged on the plate body at intervals, when the medium to be cooled flows in the flow channel 200, the medium to be cooled needs to flow through all the flow grooves 130 on the two heat exchange plates, so that the flow path of the medium to be cooled is quite long, and the long flow path makes the heat exchange of the medium to be cooled more sufficient.
In the third aspect, when the number of the flow channels 130 is large, the flow channel 130 is designed to be narrow, and the flow area of the medium to be cooled is small due to the narrow flow channel 130, and the small flow area increases the flow velocity of the medium to be cooled, and the heat of the medium to be cooled is accelerated to be lost along with the increase of the flow velocity, so that the heat exchange of the medium to be cooled is further accelerated.
In summary, the present invention provides a multi-flow heat exchange plate structure for a closed cooling tower, including two heat exchange plates attached to each other, wherein the heat exchange plates include: the plate comprises a plate body, a liquid inlet hole and a liquid outlet hole, wherein the liquid inlet hole and the liquid outlet hole are formed in the plate body; the runners are arranged on the plate body at intervals; the flow channel of any one heat exchange plate is communicated with the flow channel of the other heat exchange plate to form a flow channel, and the liquid outlet hole and the liquid inlet hole are respectively communicated with the flow channel.
