Detailed Description
The present invention is further illustrated by the following examples, but is not limited to the contents of the specification.
According to the utility model discloses an aspect discloses a plate heat exchanger with water conservancy diversion structure, include: the plate 10 is provided with a heat dissipation surface 11 for dissipating heat, and the heat dissipation surface 11 is provided with a flow guide structure for guiding cooling water so as to prolong the flow time of the cooling water. The utility model discloses a set up the water conservancy diversion structure on the slab and carry out the water conservancy diversion to the cooling water to increase the time that the cooling water flows on the slab, thereby the time of extension cooling water formation water film on the slab has greatly improved evaporation effect and cooling efficiency.
In the first embodiment shown in fig. 1 and 2, the flow guiding structure includes a plurality of flow guiding grooves 12, and the plurality of flow guiding grooves 12 are arranged at intervals. The flow velocity of water flow can be relieved by arranging a plurality of guide grooves 12, the time of forming a water film is prolonged, the evaporation capacity is increased, and the cooling efficiency is greatly improved.
In the above embodiment, the guide grooves 12 have a corrugated structure, and the cooling water flows along a corrugated path in the guide grooves 12 to prolong the flow time of the cooling water. The cooling water is mostly sprayed on the upper half part of the plate under the action of the spray pipe when the unit operates, then the cooling water flows through the corrugated grooves on the plate, because the corrugated diversion trench 12 is in a left-right zigzag form, the cooling water can be staggered left and right along a curve and repeatedly split and combined when flowing on the diversion trench 12, the cooling water can be split and combined left and right to flow downwards by utilizing the staggered shape of the left and right curved surfaces in the same diversion trench 12, the distance between the diversion trench 12 and the diversion trench 12 is short, so that the plate has the most effective area and is in full contact with the cooling water, the effective time for forming the water film on the plate can be prolonged, and the positions of the water film distribution are also uniform, thereby greatly improving the evaporation effect and the cooling efficiency.
In the second embodiment shown in fig. 3 and 4, the flow guiding structure comprises a first chute 13 and a second chute 14, and the first chute 13 and the second chute 14 are arranged in a staggered manner to form the flow guiding structure. The number of the first inclined grooves 13 is multiple, and the multiple first inclined grooves 13 are arranged at intervals; the second inclined grooves 14 are multiple, and the second inclined grooves 14 are arranged at intervals; the first chutes 13 and the second chutes 14 are staggered with each other to form a grid-type flow guide structure. The grid type flow guide structure has the advantages that the strip-shaped distribution is complicated, so that the resistance to cooling water is large, the flowing time of the cooling water in the flow guide structure is longer, the effective time of forming a water film on the plate is prolonged, and the overall evaporation effect and the cooling efficiency of the heat exchanger are greatly improved.
In the above embodiment, the plate 10 has heat dissipating surfaces 11 on both sides, and each heat dissipating surface 11 is provided with a flow guiding structure. The flow guiding structures on the two heat dissipation surfaces 11 are correspondingly arranged. Through all setting up the water conservancy diversion structure at the slab two-sided, dual increase cooling water and the effectual area of contact between the slab to the time that the extension cooling water flowed on the slab and the time that forms the water film have greatly improved the holistic evaporation effect of heat exchanger like this and have cooled down the effect.
In the above embodiment, the plate heat exchanger further includes a bracket assembly 20, where the bracket assembly 20 is used to fix the plate 10; the plate 10 is plural, and the plural plates 10 are arranged on the bracket assembly 20 at intervals. The sheet bar is fixed at two ends by using a clamping groove of the support component, one end of the sheet bar is fixed at a processed groove position on the support component, the sheet bar is clamped by using the limitation of the groove position, then a sheet metal part with holes is sleeved into a handle head at the other end of the sheet bar, the handle head and the sheet metal part are welded and fixed, and the sheet metal part and the support component are welded in a positioning manner, so that each sheet bar is fixed on the support component; and then, the spray pipe and the fixing piece are directly placed above the plate and firmly fixed on the bracket component, and then the whole plate type heat exchanger externally connected with a water source is assembled.
