Abstract
A plate type condenser heat exchange plate is formed by welding edges of two plates, wherein the edges of the plate are welded with an inlet and an outlet which are connected with an inner cavity of the heat exchange plate, and the plate is provided with a plurality of baffling lines so as to form a circulating baffling flow channel. Round and oval convex points are arranged in the flow channel area to carry out turbulence and enhance heat exchange, the round convex points not only play roles in enhancing the pressure resistance of the flow channel, but also play a role in turbulence, and the oval convex points improve the dynamic performance of the medium flow channel; it is made by two methods: firstly, rolling and forming, and then carrying out resistance welding on salient points of the plate; secondly, the two superposed sheets are welded at fixed points and then formed in a blowing mode. The round and oval convex points not only enhance the heat exchange, but also increase the mechanical strength of the plate; the plate type condensation heat exchanger has the advantages of compact structure, easy assembly, high temperature and high pressure resistance, high heat exchange efficiency and long service life.
Description
Technical Field
The invention belongs to the field of efficient heat exchange energy-saving equipment, and relates to a heat exchange plate for a plate-type condensation heat exchanger.
Background
At present, a gas-liquid phase change heat exchanger is usually a finned tube heat exchanger. The phase-change medium runs in the tube, the other medium runs on the fin side, and cross flow heat exchange is adopted between the phase-change medium and the other medium, but the heat exchange effect of the fin tube type heat exchanger is poor, so that the medium in the tube cannot be completely changed in phase, and a large amount of energy is wasted; on the other hand, the fin tube type heat exchanger has poor heat exchange capacity, needs to consume a large amount of tubes, has poor mechanical sealing performance, is easy to accumulate dust on the fin side, and simultaneously, the fins are easy to fall off to cause the increase of contact thermal resistance, so that the heat exchange capacity of the heat exchanger is greatly reduced, and the service life is reduced.
Among the prior art, the report to phase transition plate heat exchanger is less, and plate heat exchanger has compact structure, and area is little, characteristics such as heat transfer efficiency height, but traditional plate heat exchanger is compact structure, but the runner is complicated, and medium both sides flow resistance is great, and traditional plate heat exchanger needs the rubber circle to be sealed simultaneously, is not suitable for high temperature steam heat transfer, and steam takes place the phase transition simultaneously and can cause the volume to reduce by a wide margin, and traditional plate-type does not have the change on the runner sectional area, causes the fluid flow velocity after the phase transition to reach the torrent, and the heat transfer effect reduces. The salient points of other heat exchange plates on the heat exchange surface are basically circular, but the biggest defect of the circular structure is the defect of a dynamic flow channel, and heat exchange dead angles are easy to generate.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a plate type condenser heat exchange plate which has compact structure, high heat exchange efficiency and better dynamic flow,
the technical scheme adopted by the invention is as follows: the utility model provides a plate condenser heat transfer plate, its edge welding has import and the export of connecting the heat transfer plate inner chamber, and its characteristics are: the plate is provided with a plurality of baffling lines so as to form a flow passage, and the flow area of the flow passage is gradually reduced along with the deepening of the condensation process.
Furthermore, a plurality of round and oval convex points for disturbing flow and enhancing heat exchange are arranged in the flow channel area of the heat exchange plate, and the heat exchange plate is manufactured by two methods: firstly, rolling and forming, and then carrying out resistance welding on salient points of the plate; secondly, welding two overlapped plates at fixed points, and molding in a blowing mode, wherein the ratio range of the major axis and the minor axis of the ellipse is 1: 1-0.6: 0.4, and the diameter of the circular salient point is 1mm-50 mm.
The invention has the beneficial effects that: set up a plurality of baffling lines on the slab to this forms the runner, and along with the phase transition medium condensation, the volume significantly reduces, and runner flow area reduces gradually, has overcome the heat transfer process and has leaded to the volume reduction to make the velocity of flow descend because of the medium condensation phase transition is become liquid by the gaseous state, thereby influences the problem of heat transfer. Circular and oval salient points are arranged in the flow channel area to disturb flow and enhance heat exchange, and the circular and oval salient points enhance heat exchange and mechanical strength of the plate.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in figure 1, the heat exchange plate for the plate-type condensation heat exchanger is formed by welding edges of two plates, an inlet 1 and an outlet 2 which are connected with a plate heat exchange channel are welded on the edges of the two plates, a plurality of baffling lines 3 are arranged on the plates so as to form a flow channel, a condensing medium enters from the inlet 1 of the flow channel, the condensing medium is changed from a gas state to a liquid state along with the deepening of a condensation process, the volume is reduced, the flow area of the flow channel is gradually reduced by the baffling lines 3, and the problem that the flow speed is reduced due to the reduction of the volume caused by the change of the medium condensation phase from the gas state to the liquid state in the heat transfer process, so that.
Meanwhile, the circular and elliptical salient points 4 are arranged in the flow channel area for turbulence and heat exchange enhancement, and the heat exchanger can be manufactured by two methods, namely firstly, rolling forming is carried out, and then resistance welding is carried out on the salient points of the plate; secondly, the two superposed plates are welded at fixed points and then are molded in a blowing mode, and the heat exchange is enhanced and the mechanical strength of the plates is enhanced due to the round and oval salient points 4. The ratio of the major axis to the minor axis of the ellipse on the heat exchange plate ranges from 1:1 to 0.6:0.4, and the diameter of the circular salient point ranges from 1mm to 50 mm. The plate type condensation heat exchanger has the advantages of compact structure, easiness in assembly, high temperature and high pressure resistance, high heat exchange efficiency, long service life and easiness in automatic production.
The heat exchange plate sheet of the plate-type condensing heat exchanger disclosed by the invention is within the spirit and principle of the patent of the invention, and any modification, equivalent replacement, improvement and the like made by the plate-type condensing heat exchanger are included in the protection scope of the patent of the invention.
