Description

Technical Field

[0001] This invention relates to the field of heat exchange technology, specifically a heat exchange device with controllable flow path. Background Technology

[0002] Heat exchangers are indispensable key equipment in industrial production and energy utilization processes. Their performance directly affects energy conversion efficiency, production costs, and system operation stability.

[0003] A heat exchange device with publication number CN207472108U includes a heat exchange section and a water collection device. The heat exchange section includes multiple heat exchange plates, with channels for the flow of heat exchange medium restricted between adjacent heat exchange plates. The water collection device is located below the heat exchange section to collect condensate dripping from the surface of the heat exchange plates. According to this invention, the water collection device can collect condensate formed on the surface of the heat exchange section, preventing condensate from dripping onto equipment below the heat exchange section and accelerating corrosion of the equipment below the heat exchange section, thereby extending the service life of the equipment below the heat exchange section.

[0004] Although this device can effectively collect condensate to protect the equipment below compared with existing technologies, it still has certain limitations in practical applications. It cannot achieve active control of the heat exchange flow path, making it difficult to flexibly adjust the fluid flow path to match changes in heat load under different operating conditions, thus affecting further improvement of heat exchange efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a heat exchange device with controllable flow path to solve the problems raised in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a heat exchange device with controllable flow path, comprising a controller, the heat exchange device comprising a housing, wherein a heat exchange component and an adjustment component are disposed inside the housing, the adjustment component comprising an adjustment tube, an adjustment motor disposed above the adjustment tube, an adjustment wheel and a pressure regulating component disposed inside the adjustment tube, the adjustment tube being connected to the heat exchange component, and a conversion component being installed above the heat exchange component, the conversion component being electrically connected to the controller via a wire; The regulating component, in conjunction with the pressure regulating component, adjusts the flow rate and pressure of the medium within the heat exchanger. The conversion component is used to convert thermal energy into electrical energy to supplement the controller; Existing heat exchangers can only influence the internal medium through a water pump, primarily for adjusting the flow rate. They cannot balance the internal pressure of the heat exchanger through a simple structure. This application, through adjustment and pressure regulating components, can regulate the flow rate and internal pressure of the heat exchanger. Adjusting the flow rate can increase the heat exchange speed, and balancing the internal pressure can accelerate the heat exchange efficiency.

[0007] Furthermore, the pressure regulating component includes a limiting frame, a filter screen and a pressure regulating wheel between the limiting frame, the pressure regulating wheel being mounted on the limiting frame via a bearing, and a mating wheel being mounted on the adjusting wheel via a support rod, the mating wheel meshing with the adjusting wheel; When a water pump regulates the pressure inside a heat exchanger, it needs to continuously inject a medium into the heat exchanger to increase the internal pressure. However, simply increasing the internal pressure without balancing the internal pressure will not increase the heat exchange efficiency. This invention can work with the pressure regulating component to balance the internal pressure of the heat exchanger, thereby accelerating the heat exchange efficiency.

[0008] Furthermore, the adjusting wheel is installed inside the adjusting tube via a bearing, a mating disc is installed at one end of the adjusting wheel, the adjusting motor is installed on the adjusting tube via a support rod, a driving disc is installed at the output end of the adjusting motor, and the driving disc is magnetically coupled to the mating disc. Conventional transmission structures use gears or belts, which are prone to mechanical wear and noise under long-term high-speed operation, and have poor sealing performance, which may lead to leakage of the medium inside the pipe. This invention adopts a magnetic coupling connection between the drive disc and the mating disc. This design not only avoids the wear problem of traditional mechanical transmission and extends the service life of the equipment, but also effectively isolates the inside and outside of the regulating pipe, improves the sealing performance of the device, prevents the medium leakage from affecting the operation of the equipment, and reduces the noise during operation.

[0009] Furthermore, the heat exchange assembly includes several sets of heat exchange units. Each set of heat exchange units is provided with a hot flow plate, a cold flow plate and a fixed plate. The hot flow plate and the cold flow plate are provided with an inlet, an outlet and two sets of sealing ports at their four corners, respectively. The fixed plate is provided with four sets of sealing ports at its four corners.

[0010] Existing heat exchange components mostly adopt a single plate structure or a simple stacked plate group, with a fixed flow channel design, making it difficult to flexibly adjust the medium flow path according to different heat load requirements, resulting in low heat exchange efficiency under certain operating conditions. This invention divides the heat exchange component into several independent heat exchange units. Each unit is composed of a hot flow plate, a cold flow plate, and a fixed plate. By setting inlets, outlets, and sealing ports at the four corners of the hot flow plate and the cold flow plate, and cooperating with the sealing port of the fixed plate, multiple units can be connected in series or in parallel, thereby flexibly changing the overall flow channel length and cross-sectional area to adapt to different flow rates and heat exchange requirements.

[0011] Furthermore, each of the hot flow plate, cold flow plate, and fixed plate has a flow channel on one side. The flow channels at the upper and lower ends of the hot flow plate and cold flow plate are staggered. The flow channel in the middle of the hot flow plate and cold flow plate is herringbone shaped. Sealing rings are provided on the hot flow plate, cold flow plate, and fixed plate. Sealing rings are also provided around the sealing openings on the hot flow plate, cold flow plate, and fixed plate.

[0012] Conventional hot runners and cold runners typically have simple flow channels, often straight or with simple curves. This makes it easy for fluids to flow in a laminar state, leading to an increased boundary layer thickness and limited heat exchange efficiency. This invention employs a staggered flow channel design at the top and bottom of the hot runners and cold runners. When fluid enters, the staggered flow channels can divert and guide the fluid. The middle section is designed with a herringbone-shaped flow channel. This structure further enhances the turbulence of the fluid. The herringbone-shaped concave and convex structure causes the fluid to constantly change direction during flow, forming strong vortices and mixing effects, which greatly thins the heat transfer boundary layer and improves convective heat transfer efficiency.

[0013] Furthermore, when the fluid enters the hot runner or cold runner: the fluid passes through the staggered flow channels, and the staggered flow channels distribute the fluid evenly into the herringbone flow channels, balancing the pressure on the hot runner and cold runner. Conventional flow channel structures are relatively simple. While they can easily divert the medium when it enters, a single flow channel can only adapt to high pressures. However, this can affect the subsequent distribution of the medium, thus impacting its heat exchange efficiency. In this invention, even when high-pressure media enter, the staggered flow channels first distribute the high-pressure media evenly within the herringbone flow channels, thereby accelerating the heat exchange efficiency of the medium.

[0014] Furthermore, the hot runner plate, cold runner plate, and fixing plate are all made of stainless steel.

[0015] Traditional hot and cold flow plates are often made of materials like ordinary carbon steel or aluminum alloy, considering cost. While ordinary carbon steel is inexpensive, it has poor corrosion resistance and is prone to rusting in heat exchange environments where it is in long-term contact with water or corrosive media. This not only affects heat exchange efficiency but also causes impurities from rust to clog flow channels and shorten equipment lifespan. Aluminum alloys, while having low density and decent thermal conductivity, have relatively low strength and are prone to deformation under high operating pressures. Furthermore, their surface oxide film is not stable enough in certain media, posing a corrosion risk. In contrast, this invention uses stainless steel for the hot and cold flow plates and the fixing plate. Stainless steel, with its excellent corrosion resistance, can effectively resist the erosion of various media during heat exchange, ensuring that the plates maintain a good surface condition and structural integrity over a long period, thereby maintaining stable heat exchange performance.

[0016] Furthermore, the conversion component includes two ceramic plates, with multiple sets of N-type semiconductors and P-type semiconductors disposed between the two ceramic plates, and copper plates installed between adjacent N-type semiconductors and P-type semiconductors. The conversion component is electrically connected to the controller via wires. Existing heat exchange devices often have a large amount of waste heat that is not effectively utilized during operation. This waste heat is usually wasted directly in the form of heat dissipation, which not only reduces energy utilization but may also affect the ambient temperature around the equipment. The conversion component set in this invention converts thermal energy into electrical energy, and the generated electrical energy is transmitted to the controller through wires. At the same time, the conversion component can also accelerate the heat exchange efficiency of the heat exchange component.

[0017] Furthermore, the controller is installed inside the enclosure, and a control panel is provided outside the enclosure. The control panel and the controller are connected by electrical signals via wires. Existing plate heat exchangers are not equipped with integrated intelligent control systems and mostly rely on complex external control equipment or manual adjustment, which is cumbersome to operate and has a slow response speed, making it difficult to achieve precise real-time control. When using this invention, the operator can control the controller through the control panel to indirectly operate the device.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. By adjusting the regulating wheel, pressure regulating component and regulating motor in the regulating component, the medium flow rate and pressure can be adjusted in real time according to the actual heat exchange requirements, optimize the heat exchange process, avoid energy waste, and improve the system response speed and operation stability; 2. The heat exchange components adopt an alternating stacked design of hot flow plates, cold flow plates and fixed plates, with staggered flow channels and herringbone flow channels inside the plates, which makes the medium distribution more uniform, enhances the turbulence effect, destroys the thermal boundary layer, and significantly improves the heat exchange efficiency and heat transfer uniformity. 3. The conversion component utilizes the Seebeck effect to directly convert the thermal energy generated during the heat exchange process into electrical energy, which powers the controller, sensors, and other components inside the device. This achieves energy recovery and self-supply, improving overall energy utilization efficiency and system sustainability. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example: Figures 1-9 As shown, the present invention provides a heat exchange device with controllable flow path, including a controller 6. The heat exchange device includes a housing 1, inside which a heat exchange component 2 and an adjustment component 3 are arranged. The adjustment component 3 includes an adjustment pipe 31, an adjustment motor 33 is arranged above the adjustment pipe 31, and an adjustment wheel 32 and a pressure regulating component 5 are arranged inside the adjustment pipe 31. The adjustment pipe 31 is connected to the heat exchange component 2, and a conversion component 4 is installed above the heat exchange component 2. The conversion component 4 is electrically connected to the controller 6 through a wire. The regulating component 3, in conjunction with the pressure regulating component 5, adjusts the flow rate and pressure of the medium within the heat exchange device. The conversion component 4 is used to convert thermal energy into electrical energy to supplement the controller 6; When using this device, an external input terminal is required to allow the heat exchange medium to enter the device. The medium first passes through the regulating component 3, which is located at the input terminal of the heat exchange component 2. The regulating component 3 regulates the flow rate and pressure of the medium entering the heat exchange component 2, thus adjusting the pressure of the medium inside the heat exchange component 2. The reason why the regulating component 3 and the pressure regulating component 5 are located at the input terminal of the heat exchange component 2 is to stabilize the flow rate and pressure entering the heat exchange component 2. Regulating the flow rate at the input terminal of the heat exchange component 2, compared to regulating the flow rate at the output terminal, allows for pressure balance within the heat exchange component 2. Under a balanced pressure state, the medium can be absorbed more quickly within the heat exchange component 2. In heat exchange, under the drive of the regulating motor 33, the regulating wheel 32 rotates, thereby increasing or decreasing the flow rate of the medium by the blades at the bottom of the regulating wheel 32. During the rotation of the regulating wheel 32, the pressure regulating component 5 is driven to adjust or reduce the internal pressure of the heat exchange component 2, so as to balance the heat exchange component 2 and enable the heat exchange component 2 to exchange heat with the medium more quickly. At the same time, the conversion component 4 of the device can absorb a certain amount of heat, thereby accelerating the heat exchange process. The conversion component 4 can convert the thermal energy in the device into electrical energy. The conversion component 4 is connected to the controller 6, and the generated electricity can supplement the regional equipment for use.

[0023] like Figure 2 and Figure 4 As shown, in this embodiment, specifically, the pressure regulating component 5 includes a limiting frame 51, a filter screen and a pressure regulating wheel 52 between the limiting frames 51, the pressure regulating wheel 52 is mounted on the limiting frame 51 by a bearing, and a mating wheel 53 is mounted on the adjusting wheel 32 by a support rod, the mating wheel 53 meshing with the adjusting wheel 32; When the pressure regulating component 5 is in use, the mating wheel 53 will rotate under the drive of the adjusting wheel 32. Since the mating wheel 53 meshes with the pressure regulating wheel 52, its rotation will directly drive the pressure regulating wheel 52 to rotate synchronously within the limiting frame 51. The filter screen is fixedly installed between the limiting frames 51 to perform preliminary filtration of the heat exchange medium flowing through, preventing impurities from entering the subsequent heat exchange component 2 and causing blockage. When the pressure regulating wheel 52 rotates, its blades will form different relative positional relationships with the filter screen. When the pressure regulating wheel 52 stops, it will block the filter screen and also block the flow cross-sectional area of ​​the medium, thereby increasing the resistance to the flow of the medium and reducing the pressure of the medium entering the heat exchange component 2. Meanwhile, the pressure regulating wheel 52 rotates forward and backward multiple times, which can disrupt the stable medium flow rate and thus significantly reduce the medium flow rate. Conversely, the eddies generated by the rotation of the pressure regulating wheel 52 can also increase the medium flow rate, thereby increasing the pressure when the medium enters the heat exchange component 2.

[0024] like Figures 3-4 and Figure 9As shown, in this embodiment, specifically, the adjusting wheel 32 is installed inside the adjusting tube 31 through a bearing, a mating disc 321 is installed at one end of the adjusting wheel 32, the adjusting motor 33 is installed on the adjusting tube 31 through a support rod, and a driving disc 331 is installed at the output end of the adjusting motor 33. The driving disc 331 and the mating disc 321 are magnetically coupled. The adjusting wheel 32 is mainly driven by the adjusting motor 33. In actual use, the drive disc 331 starts to rotate under the drive of the adjusting motor 33. Since the drive disc 331 and the mating disc 321 are magnetically coupled, there is no direct mechanical contact between them. Instead, power is transmitted through magnetic force. When the drive disc 331 rotates, it generates a changing magnetic field. Under the action of the magnetic force, the mating disc 321 rotates synchronously with the drive disc 331, thereby driving the adjusting wheel 32 to rotate inside the adjusting tube 31. This magnetic coupling connection method can effectively isolate the adjusting motor 33 from the medium inside the adjusting tube 31, avoiding damage to the motor due to medium leakage, while reducing mechanical wear and improving the stability and service life of the adjusting wheel 32. For example, when the regulating motor 33 receives a control signal to increase the flow rate, the drive disc 331 accelerates its rotation, and the magnetic force drives the mating disc 321 and the regulating wheel 32 to accelerate their rotation synchronously. The regulating wheel 32 then drives the mating wheel 53 to rotate through the support rod, thereby adjusting the pressure regulating component 5 to the state of increasing the flow rate. Conversely, when it is necessary to reduce the flow rate, the regulating motor 33 decelerates, the drive disc 331 speed decreases, the mating disc 321 and the regulating wheel 32 decelerate accordingly, and the pressure regulating component 5 is adjusted to the state of reducing the flow rate.

[0025] like Figures 6-8 As shown in this embodiment, specifically, the heat exchange assembly 2 includes several sets of heat exchange units. Each set of heat exchange units is provided with a hot flow plate 21, a cold flow plate 22 and a fixed plate 23. The hot flow plate 21 and the cold flow plate 22 are respectively provided with an inlet, an outlet and two sets of sealing ports at the four corners. The fixed plate 23 is provided with four sets of sealing ports at the four corners. Hot flow plate 21, cold flow plate 22 and fixed plate 23 are stacked alternately, and the four corner sealing ports cooperate with the corresponding sealing ports on hot flow plate 21 and cold flow plate 22 to form independent hot medium channels and cold medium channels. The hot flow plate 21 has a hot medium flow channel inside, and the cold flow plate 22 has a cold medium flow channel that is opposite to or crosses the flow channel of the hot flow plate 21. When the hot medium enters from the inlet of the hot flow plate 21, it will flow along the preset flow channel and exchange heat with the cold flow plate 22, and then flow out from the outlet. The cold medium flows in a similar manner in the cold flow plate 22, absorbing or releasing heat, realizing efficient heat transfer between the two media.

[0026] like Figures 6-7As shown in this embodiment, specifically, one side of the hot flow plate 21, the cold flow plate 22, and the fixed plate 23 is respectively provided with a flow channel. The flow channels at the upper and lower ends of the hot flow plate 21 and the cold flow plate 22 are respectively staggered. The flow channel in the middle of the hot flow plate 21 and the cold flow plate 22 is herringbone shaped. Sealing rings are provided on the hot flow plate 21, the cold flow plate 22, and the fixed plate 23. Sealing rings are also provided around the sealing openings on the hot flow plate 21, the cold flow plate 22, and the fixed plate 23. Because flow channels are provided on the hot flow plate 21 and the cold flow plate 22 respectively, when the medium flows inside the hot flow plate 21 and the cold flow plate 22, it can fully contact the plate body along the preset path. The staggered flow channels at the upper and lower ends of the hot runner 21 and cold runner 22 prevent direct mixing of the hot and cold media when entering and exiting the heat exchange unit, while guiding the media to be evenly distributed in the central region. The herringbone flow channel design in the middle significantly increases the flow path length and turbulence of the media within the plate, disrupting the boundary layer formed on the plate wall during media flow, thereby enhancing the convective heat transfer coefficient between the media and the plate. When the hot media flows in the herringbone flow channel of the hot runner 21, its flow direction changes continuously with the curvature of the channel, causing strong disturbance and mixing within the media, ensuring that the heat in the hot media can be quickly transferred to the hot runner 21. Similarly, when the cold media flows in the herringbone flow channel of the cold runner 22, it also enhances the heat exchange with the cold runner 22 through similar disturbances, thereby increasing the heat transferred between the hot runner 21 and the cold runner 22 through the fixed plate 23, ultimately improving the heat exchange efficiency of the entire heat exchange assembly 2.

[0027] like Figures 6-7 As shown in this embodiment, specifically, when the fluid enters the hot flow plate 21 or the cold flow plate 22: the fluid passes through the staggered flow channels, and the staggered flow channels evenly distribute the fluid into the herringbone flow channels, balancing the pressure on the hot flow plate 21 and the cold flow plate 22. When the medium enters the hot runner 21 or the cold runner 22, it first comes into contact with the staggered flow channels at the top and bottom. These staggered flow channels act as a flow distribution hub, which can evenly guide the incoming medium flow to the herringbone flow channel area in the middle. For example, if the hot medium flows in from the inlet of the hot runner 21, the staggered flow channels will disperse the medium flow that may have been concentrated on one side into multiple small flow streams, which are then guided to different inlet ends of the herringbone flow channels. This avoids the situation where the flow rate in a local flow channel is too large and the flow rate in other areas is insufficient due to the direct impact of the medium.

[0028] like Figures 6-8 As shown, in this embodiment, the hot flow plate 21, cold flow plate 22 and fixing plate 23 are all made of stainless steel. Because the hot flow plate 21, cold flow plate 22, and fixed plate 23 are all made of stainless steel, they have good thermal conductivity and corrosion resistance, and can adapt to long-term scouring and high-temperature environments of different types of heat exchange media. The relatively high thermal conductivity of stainless steel can effectively reduce heat loss during the transfer process of the plates while ensuring structural strength, thus ensuring the heat exchange efficiency between the hot and cold media. In addition, stainless steel also has strong compressive strength and processing performance, which can meet the precision forming requirements of the complex flow channels inside the hot flow plate 21 and cold flow plate 22, ensuring smooth flow channel surfaces, reducing medium flow resistance, and further improving heat exchange efficiency and the stability of device operation.

[0029] like Figure 5 As shown, in this embodiment, specifically, the conversion component 4 includes two ceramic plates 41, with multiple sets of N-type semiconductors 42 and P-type semiconductors 43 disposed between the two ceramic plates 41, and copper plates installed between adjacent N-type semiconductors 42 and P-type semiconductors 43. The conversion component 4 is electrically connected to the controller 6 via wires. When the conversion component is in use, when the heat exchange component 2 exchanges heat, the temperature difference between the hot medium and the cold medium will cause a temperature gradient to be generated at both ends of the ceramic plate 41 in the conversion component 4. Under the action of this temperature gradient, the N-type semiconductor 42 and the P-type semiconductor 43 located between the two ceramic plates 41 will undergo the Seebeck effect, that is, electrons and holes will move in a direction driven by the temperature difference, thereby generating an electromotive force at both ends of the semiconductor material.

[0030] like Figure 1 and Figure 3 As shown, in this embodiment, specifically, a controller 6 is installed inside the housing 1, and a control panel is provided outside the housing 1. The control panel and the controller 6 are connected by wires for electrical signals. Through the control panel, operators can intuitively set the operating parameters of the heat exchanger, such as the target heat exchange, medium flow range, and temperature threshold. The control panel is usually equipped with a display screen and buttons. The display screen is used to show the current working status of the device in real time, including key data such as real-time flow, inlet and outlet temperatures, valve core opening of regulating component 3, and power generation of conversion component 4, so that operators can monitor the operation of the device at any time.

[0031] Working Principle: When using this device, an external input terminal is required to allow the heat exchange medium to enter. The medium first passes through regulating component 3, which is located at the input terminal of heat exchange component 2. Regulating component 3 adjusts the flow rate and pressure of the medium entering heat exchange component 2, thereby regulating the pressure of the medium inside heat exchange component 2. The reason why regulating component 3 and pressure regulating component 5 are located at the input terminal of heat exchange component 2 is to stabilize the flow rate and pressure entering heat exchange component 2. Regulating the flow rate at the input terminal of heat exchange component 2, compared to regulating the flow rate at the output terminal, allows for pressure balance within heat exchange component 2. Under pressure balance, the medium can flow smoothly within heat exchange component 2. To achieve faster heat exchange, in practical use, the regulating wheel 32 rotates under the drive of the regulating motor 33, thereby increasing or decreasing the flow rate of the medium by the blades at the bottom of the regulating wheel 32. During the rotation of the regulating wheel 32, it drives the pressure regulating component 5, which adjusts or reduces the internal pressure of the heat exchange component 2 to balance the heat exchange component 2, enabling the heat exchange component 2 to exchange heat with the medium more quickly. At the same time, the conversion component 4 of the device can absorb a certain amount of heat, thereby accelerating the heat exchange process. The conversion component 4 can convert the thermal energy in the device into electrical energy. The conversion component 4 is connected to the controller 6, and the generated electricity can supplement the regional equipment for use.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
