Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchange, and in particular relates to a heat exchange plate and a heat exchange device. Background Art

[0002] The interlayer heat exchanger is formed by a sandwich between two adjacent plates. The cold and hot fluids are separated by a solid wall (tube or plate) and do not mix. It involves the transfer and conversion of heat. The heat exchange is carried out through the interlayer to make the fluid temperature reach the specified index of the process to meet the needs of the process conditions. The gap between the two plates is usually connected by a pipe or a sealing gasket to form a closed environment that can loosely accommodate the flow and transfer of materials. It is suitable for high temperature, high pressure, high viscosity, and easy to scale fluids.

[0003] When the heat exchanger of the prior art is exchanging heat, the fluid enters and exits between the two heat exchange plate interlayers. Since the heat exchange medium inside the heat exchange plate will be affected by the external environment at the edge, heat loss of the heat exchange medium in the edge part of the heat exchange plate will occur, and the heat exchange effect in the middle position of the heat exchange surface of the heat exchange plate is better than the heat exchange effect at the edge position of the heat exchange surface; however, the heat exchange plate of the prior art is not provided with a guide structure. When the fluid exchanges heat on the heat exchange surface of the heat exchange plate from the blanking position, the surface blanking will pass through not only the middle position but also the edge position, and the fluidity of the fluid at the edge position is poor, which will cause the fluid to flow slowly at the edge position where the heat exchange effect is poor, resulting in poor heat exchange effect of the fluid in the heat exchanger. In addition, in the existing heat exchanger, the upper part of the heat exchange plate not only acts as a heat exchange wall for heat exchange, but also plays a bearing role in supporting the top of the heat exchange plate. During design, in order to ensure the bearing capacity of the heat exchange plate, the wall thickness of the heat exchange plate is usually designed to be larger, which is not conducive to heat transfer and heat exchange. Utility Model Content

[0004] The purpose of the utility model is to solve the deficiencies in the prior art and provide a heat exchange plate and a heat exchange device.

[0005] In order to achieve the above-mentioned purpose, a heat exchanger plate includes a heat exchange core, wherein the upper surface of the heat exchange core is provided with a plurality of guide channels, and the heat exchange core is provided with a plurality of confluence outlets, one end of each guide channel extends to the edge of the heat exchange core, and the other end is connected to each confluence outlet, and the confluence outlet is connected to the blanking position on the upper surface of the heat exchange core through the guide channel. In this solution, the heat exchange plate is provided with a guide channel extending to the edge so that the fluid can be guided into the guide channel, which helps to guide the fluid from the edge position with poor heat exchange effect to the middle position with good heat exchange effect, reduce the residence time of the fluid at the edge position of the heat exchange plate, and improve the heat exchange efficiency. In addition, by constructing a guide channel on the upper surface of the heat exchange core, the wall thickness between the bottom surface of the guide channel and the inner surface of the heat exchange core can be effectively reduced while ensuring the bearing capacity of the heat exchange core, which is more conducive to heat transfer and heat exchange. Moreover, by constructing a guide channel on the upper surface of the heat exchange core, the surface area of ​​the upper surface of the heat exchange core can be further increased, thereby effectively increasing the contact area between the external liquid and the upper surface of the heat exchange core, which is more conducive to heat transfer and heat exchange and achieves better heat exchange effects.

[0006] Optionally, the guide channel is arranged on the upper surface of the heat exchange core, and the upper surface of the heat exchange core is an inclined surface, and the inclined surface is inclined downward in the direction of the confluence outlet.

[0007] Among them, under the inclination of the inclined surface, the fluid on the heat exchange plate can be drained to the inclined lower end of the heat exchange plate, driving the fluid to flow faster on the inclined surface, and the inclination angle of the inclined surface is set between 1-3° to control the flow speed of the fluid within a controllable range, so that the fluid speed will not be too fast to affect the heat exchange effect.

[0009] Among them, the middle part of the heat exchange core is the position with the best heat exchange effect, and the guide channels are symmetrically distributed from the middle position of the heat exchange plate to both sides. In order to ensure that the fluid on the heat exchange plate can fully exchange heat, multiple guide channels are arranged on the heat exchange plate to guide the fluid distributed on the side and the fluid in the middle part on the heat exchange plate and improve the utilization rate of the heat exchange plate area, thereby improving the heat exchange effect.

[0010] Optionally, a fluid cavity is provided inside the heat exchange core, and a water inlet interface and a water outlet interface are provided on both sides of the heat exchange core, respectively. The water inlet interface and the water outlet interface are connected to the fluid cavity inside the heat exchange core, and a reinforcing rib plate is provided in the fluid cavity. The reinforcing rib plate in the fluid cavity forms one or more water channels between the water inlet interface and the water outlet interface, so that the fluid in the fluid cavity stays longer, thereby improving the heat exchange effect of the heat exchanger.

[0011] The heat exchanger fins in the prior art heat exchanger adopt a horizontal structure. The connection of the heat exchanger is often connected by a number of hexagonal screws, which is complicated to install and the fastening method is unreliable. The poor sealing effect of the heat exchanger leads to poor heat exchange efficiency. In order to solve this technical problem, the utility model provides a heat exchange device, which also includes an upper sealing plate, a bottom plate and a fastening mechanism. Several layers of heat exchange fins are stacked between the upper sealing plate and the bottom plate. The fastening mechanism is arranged on the side of the upper sealing plate, the bottom plate and the heat exchange fins.

[0013] Optionally, a Z-shaped material layer is formed between the heat exchange fins.

[0014] Among them, the converging outlets of two adjacent heat exchanger plates coincide with the blanking positions of the guide channels on the heat exchanger plates. The two adjacent heat exchanger plates are placed in opposite directions so that the converging outlets are staggered to form a Z-shaped material flow layer, which fully utilizes the material flow layer area of ​​the heat exchanger plates to improve the heat exchange effect.

Compared with fixing methods such as screws or adhesion, it will not cause damage to the heat exchanger, thereby improving the installation and disassembly efficiency.

[0025] In order to make the purpose, technical solutions and advantages of the embodiments more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the attached claims.

[0026] It should be noted that all actions to obtain signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located, and with the authorization given by the owner of the corresponding device.

[0027] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", are defined according to the corresponding parts' own contours. The terms used in the present disclosure, such as "first" and "second", etc., are used to distinguish one element from another element and do not have order and importance.

[0028] Example 1

[0029] Basically as attached Figure 1 To Attachment Figure 2 As shown, a heat exchange plate provided in this embodiment includes a heat exchange core 1, which is a heat transfer structure made of a metal plate with good thermal conductivity and an internal cavity for liquid flow. A fluid cavity 4 is arranged inside the heat exchange core 1, and the upper surface of the heat exchange core 1 is arranged as an inclined surface 5. Hot fluid flows into the fluid cavity 4, and cold fluid flows into the upper surface of the heat exchange core 1, and heat is transferred through the metal plate of the heat exchange core 1.

[0030] Among them, at least one guide channel 2 is provided on the upper surface of the heat exchange core 1, and at least one confluence outlet 3 is provided on the heat exchange core 2. The head end of the guide channel 2 extends to the corner position of the heat exchange core 1, and the end of the guide channel 2 extends to the confluence outlet 3 on the heat exchange plate. The guide channel 2 is used to guide the cold fluid flowing into the heat exchange core 1, so that the cold fluid is guided to the confluence outlet 3 along the path specified by the guide channel 2. The heat exchange plate is provided with a guide channel extending to the edge so that the fluid can be guided into the guide channel 2, which helps to guide the fluid from the edge position with poor heat exchange effect to the middle position with good heat exchange effect, reduce the residence time of the fluid at the edge position of the heat exchange plate, and improve the heat exchange efficiency.

[0031] The confluence outlet 3 is set as a through hole to connect the upper surface and the lower surface of the heat exchange plate. The through hole of the confluence outlet 3 is separated from the fluid cavity 4 inside the heat exchange core 1 by a sleeve and sealed with a sealing structure to prevent external cold flow from entering the fluid cavity 4.

[0032] Basically as attached Figure 3 As shown, the cold fluid on the upper surface of the heat exchange core 1 flows into the confluence outlet 3 after heat exchange, and the number of the confluence outlets 3 is not less than one; according to the temperature, viscosity and functional properties of the cold fluid introduced, multiple guide channels 2 can be selected to correspond to multiple confluence outlets 3, and the flow path of the guide channel 2 is set to be curved or straight, and the end of the guide channel 2 extends to the confluence outlet 3, so that the cold fluid can make full use of the heat exchange area of ​​the heat exchange plate and improve the heat exchange effect.

[0033] The heat exchange plate used in this embodiment is rectangular in shape, and the guide channel 2 is connected to and guides the position on the side of the heat exchange plate where it is difficult to guide the fluid. The guide channel 2 formed by the upper metal plate of the heat exchange plate and the flow position on the side of the heat exchange plate are stamped and set to form a concave sheet metal structure. The bottom of the guide channel 2 and the corner of the heat exchange plate is a downward concave arc surface. The height of the guide channel 2 is 1-5mm. The guide channel 2 helps the flow of the fluid and reduces the loss on the side of the heat exchange plate.

[0034] The cold fluid falling from the upper confluence outlet 3 to the side drop of the guide channel 2 of the lower heat exchange plate is guided at the downward arc surface formed by the guide channel 2, so that the cold fluid can be gathered from the side position to the middle position with better heat exchange effect to the guide channel 2 for heat exchange.

[0035] Example 2

[0036] The upper metal plate constituting the heat exchange core 1 in the heat exchange plate in this embodiment is tilted to form an inclined surface 5, and the inclined surface 5 is tilted downward in the direction of the confluence outlet 3, and the inclination angle of the inclined surface 5 is 1-3°. The cold fluid can flow in the direction of the confluence outlet 3 under the action of gravity on the inclined surface 5. The inclined surface 5 is the heat exchange plane of the heat exchange plate. If the inclination angle of the inclined surface 5 is too large, the flow speed of the cold fluid on the heat exchange plate will be too fast. The cold water flow enters the confluence outlet for discharge before it has fully contacted with the heat exchange plane for heat exchange, resulting in poor heat exchange effect. If the inclination angle of the inclined surface 5 is too small, the effect of accelerating drainage cannot be achieved under the action of fluid tension. In this embodiment, the inclination angle of the inclined surface 5 is set to between 1-3°, so that the speed of the fluid flow is controlled within a controllable range, and the speed of the fluid will not be too fast to affect the heat exchange effect.

[0037] The inclination angle formed by the inclined surface 5 toward the converging outlet 3 cooperates with the arc surface at the end of the guide flow 2 of the heat exchange core 1 to form a guide cooperation.

[0038] When the cold fluid is attached to the heat exchange plate, after the cold fluid on the heat exchange plate is collected through the guide channel 2 , the inclined surface of the heat exchange plate accelerates the guide of the cold fluid entering the guide channel 2 .

[0039] The upper and lower metal plates of the heat exchange core 1 are selected from materials with excellent thermal conductivity such as titanium, stainless steel, copper, and alloys, and matching path grooves are processed according to the characteristics of the guide channel set in this embodiment. The metal plates of the heat exchange core 1 are coated on their surfaces after processing and shaping.

The number and area of ​​the heat exchange plates are determined according to the volume and properties of the cold fluid to be heat exchanged. The heat exchange device is a sealed rectangular container. The height of the material passing layer 13 formed between the upper sealing plate 8 and the heat exchange plates and between the plurality of heat exchange plates is set to 5-20 cm. The outer side of the material passing layer 13 formed by the upper sealing plate 8 and the plurality of layers of heat exchange plates is sealed by an elastic sealing ring 10.

[0042] The fluid chambers 4 of several layers of heat exchange plates are connected by U-shaped tubes 14. The two sides of the fluid chamber 4 are respectively provided with connecting joints of the U-shaped tubes 14. The fluid chamber 4 is connected to a water source of hot flowing water set outside through the connecting joints; the connecting joints are divided into a water inlet joint 6 and a water outlet joint 7.

After being connected in sequence, the water outlet joint 7 of the top heat exchanger is connected to the wastewater treatment mechanism, so that the fluid chambers 4 in several heat exchanger plates pass through multiple U-shaped tubes 14 so that the channel of the hot fluid is a channel that continuously flows upward.

[0044] The upper surface of the heat exchanger plate of the present application is set as an inclined surface 5, and the side of the heat exchanger plate with a higher height is set as a water outlet joint 7, and the side of the heat exchanger plate with a lower height is set as a water inlet joint 6. A reinforcing rib plate is set in the fluid cavity 4, and the reinforcing rib plate in the fluid cavity 4 forms one or more water flow channels between the water inlet interface and the water outlet interface, so that the fluid in the fluid cavity stays for a longer time, thereby improving the heat exchange effect of the heat exchanger, and slowing down the fluid speed in the fluid cavity 4 can also effectively save energy and reduce emissions.

[0045] The upper sealing plate 8 is provided with a material inlet interface 11, and the bottom plate 9 is provided with a material outlet 12. The heat exchanger is connected to the feeding device through the material inlet interface 11 provided on the upper sealing plate 8, and the cold running water enters the heat exchanger through the material inlet interface 11 and starts the heat exchange process.

[0046] The position of the feed interface 11 and the position of the confluence outlet of the heat exchanger plate set on the top layer of the heat exchange device are staggered and set on both sides of the heat exchange device. The cold water introduced by the feed interface 11 enters the inside of the heat exchanger and contacts the heat exchanger plate. The positions of the confluence outlets 3 of several heat exchanger plates between the upper sealing plate 8 and the bottom plate 9 are staggered and set on both sides of the heat exchange device. The cold fluid forms a Z-shaped heat exchange channel in the material layer 13 between the heat exchanger plates, and the cold fluid can fully exchange heat with the heat exchanger plates. The number of feed interfaces 11 and discharge ports 12 set on the upper sealing plate 8 and the bottom plate 9 is consistent with the number of confluence outlets 3 of the heat exchanger plates. The confluence outlets 3 of two adjacent heat exchanger plates overlap with the blanking positions of the guide channel 2 on the heat exchanger plates. The two adjacent heat exchanger plates are placed in opposite directions so that the confluence outlets 3 are staggered to form a Z-shaped material layer 13, making full use of the material layer area of ​​the heat exchanger plates to improve the heat exchange effect.

[0047] The position of the discharge port 12 is aligned with the position of the confluence outlet 3 of the heat exchange plate arranged at the bottom layer of the heat exchange device. The upper surface of the bottom plate 9 abuts against the heat exchange plate arranged at the bottom layer. Support feet are arranged at the bottom of the bottom plate 9.

Two or more fastening mechanisms are evenly arranged on each side of the heat exchange device, so that the force of the heat exchange device is even after assembly, and the sealing effect and stability effect of the heat exchange device are improved.

[0050] In actual use, when the upper sealing plate, several heat exchanger plates and the bottom plate are installed layer by layer in the heat exchanger, there is a height difference at the periphery of the heat exchanger plates due to a certain inclination angle of the inclined surface 5 of the heat exchanger plates. The upper sealing plate 8 and the bottom plate 9 are squeezed by the fastening mechanism, and the elastic sealing ring 10 performs adaptive height adjustment in the interlayer of the material feeding layer according to the pressure it is subjected to.
