Description

Technical Field

[0001] This invention relates to the field of heat exchange equipment technology for refrigeration systems, and in particular to an integrated, pressurized microchannel condenser. Background Technology

[0002] Microchannel heat exchangers are widely used in many industries such as aerospace, metallurgy, chemical engineering, and cryogenics due to their compact structure, high pressure resistance, high heat exchange efficiency, strong adaptability, and good economic performance. However, because the welding process of their heat exchange core and end caps is relatively complex, the manufacturing cost of pressure-bearing microchannel heat exchangers by domestic manufacturers is currently high and the manufacturing process is relatively complicated.

[0003] Among existing microchannel heat exchanger fabrication technologies, printed plate heat exchangers, as a novel, more efficient, and compact type of microchannel heat exchanger, have attracted widespread attention from numerous enterprises and scholars. This type of heat exchanger uses chemical etching to create bottomed microchannels on its surface to facilitate the flow of the heat exchange medium. Multiple layers of heat exchange plates are then stacked and connected together via diffusion welding. However, the flow channels formed on the heat exchange plates in this type of heat exchanger are single channels with limited shape, preventing sufficient mixing and turbulence of the fluid, resulting in inadequate heat transfer. Summary of the Invention

[0004] In this section, as well as in the abstract and title of this application, some simplifications or omissions may be made to avoid obscuring the purpose of this section, the abstract, and the title of this application, and such simplifications or omissions shall not be used to limit the scope of the invention.

[0005] The purpose of this invention is to provide an integrated, pressurized microchannel condenser.

[0006] Therefore, its purpose is to solve the following problems: the flow channels formed on the heat exchange plates of current high-pressure microchannel heat exchangers are single channels, which prevents the fluid from being fully mixed and forming turbulence, resulting in insufficient heat exchange, and the problem that welding of the end caps can easily cause heat exchanger leakage.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0040] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0041] Example 1

[0042] Reference Figure 1-3 This is the first embodiment of the present invention, which provides an integrated pressure-bearing microchannel condenser, including a guard plate assembly 100, which includes two symmetrically distributed upper and lower guard plates 101, and a flange connecting block 102 disposed at one end of the upper and lower guard plates 101; a heat exchange assembly 200 disposed within the guard plate assembly 100, the heat exchange assembly 200 including a cold flow assembly 201 and a hot flow assembly 202 alternately disposed inside the upper and lower guard plates 101, and an intermediate partition 203 separating each heat exchange assembly 200; a hot fluid assembly 300, which includes hot fluid side guide members 301 fixedly disposed at both ends of the fluid inlet and outlet of the heat exchange assembly 200; and a cleaning assembly 400, which includes a rotating member 401 disposed on the flange connecting block 102, and a power member 402 for driving the rotating member 401 to rotate is installed inside the flange connecting block 102.

[0043] Specifically, by installing the hot fluid side guide 301 at the fluid inlet and outlet of the heat exchange component 200, the uniform distribution of fluid within the heat exchange component 200 is facilitated, reducing flow dead zones. When high-temperature, high-pressure refrigerant gas enters the interior of the heat exchange component 200 from the inlet end, the fluid impacts, tumbles, splits, and merges within the flow channel of the hot fluid component 202. Compared to traditional printed plate heat exchangers, the fluid flow is more diverse, and heat exchange is more thorough.

[0044] Furthermore, a gasket 102a is provided between the flange connecting block 102 and the upper and lower guard plates 101. The upper and lower guard plates 101 are fixed to the flange connecting block 102 and the gasket 102a by bolts. A cold fluid inlet pipe 102b communicating with the liquid inlet end of the heat exchange assembly 200 is fixed on the flange connecting block 102. The cold flow assembly 201 includes a cold fluid channel 201a and a cold fluid seal 201b, and the hot flow assembly 202 includes a hot fluid channel 202a and a hot fluid seal 202b. A single heat exchange core is composed of several layers of cold fluid channels 201a and hot fluid channels 202a. Both the cold fluid seal 201b and the hot fluid seal 202b are fixedly installed on the upper and lower guard plates 101. The interior of the hot fluid channel 202a adopts a serrated fin or irregular fin structure, and the height of the cold fluid seal 201b and the hot fluid seal 202b is slightly lower than the height of the heat exchange assembly 200. The hot fluid side guide 301 includes a first guide 301a and a second guide 301b. The first guide 301a is vertically fixed to the second guide 301b. The upper and lower guard plates 101 are provided with two connecting pipes 302 that are respectively connected to the inlet and outlet ends of the hot fluid side guide 301.

[0045] The cold flow assembly 201 and the hot flow assembly 202 are placed alternately, with a partition 203 separating each heat exchange assembly 200. Each heat exchange core consists of several layers of cold fluid channels 201a and hot fluid channels 202a. In this application, the height of the cold fluid seal 201b and the hot fluid seal 202b is required to be slightly lower than that of the heat exchange fluid channel 202a to prevent open welds and cracking during welding.

[0046] Furthermore, by installing the hot fluid side guide 301 at the fluid inlet and outlet of the heat exchange assembly 200, the uniform distribution of fluid within the heat exchange assembly 200 is facilitated, reducing flow dead zones. When high-temperature, high-pressure refrigerant gas enters the interior of the heat exchange assembly 200 from the inlet end, the hot fluid channel 202a can employ various structures such as serrated fins or irregularly shaped fins. The fluid collides, tumbles, splits, and merges within the flow channel of the hot fluid assembly 202. Compared to traditional printed plate heat exchangers, the fluid flow is more diverse, and heat exchange is more thorough. Cold fluid enters the heat exchange assembly 200 through the cold fluid inlet pipe 102b, exchanging heat with the high-temperature, high-pressure gas on the other side of the intermediate partition 203. The condensed and liquefied refrigerant liquid flows out of the heat exchanger through the connecting pipe 302 at the outlet end.

[0047] The hot fluid channel 202a adopts an integrated structure, which offers higher welding strength and saves labor costs compared to the traditional long seal plus short seal design. Furthermore, a positioning pin structure is installed inside the heat exchange component 200, which effectively improves assembly accuracy and saves assembly time.

[0048] The cold flow assembly 201 and the hot flow assembly 202 can be made of aluminum, stainless steel or titanium alloy plates, depending on the heat exchange and pressure requirements.

[0049] Secondly, the heat exchange component 200 is brazed in a high-temperature vacuum furnace. Traditionally, after the microchannel heat exchange core is welded in a vacuum furnace, inlet and outlet end caps on the hot fluid side and the cold fluid side need to be welded around the core. The temperature during argon arc welding exceeds 1500℃, while the secondary melting temperature of the nickel-based solder used in vacuum brazing is approximately 1150℃. Therefore, regardless of whether argon arc welding or laser welding is used, the brazing solder at the welding location of the heat exchanger core will inevitably undergo secondary melting. Furthermore, the thermal stress deformation generated during welding can cause the seals to deform and crack. Therefore, this invention allows the upper and lower protective plates 101 and the heat exchange component 200 to be welded in a vacuum furnace in one step, avoiding the problems of cracking and leakage in the heat exchange core caused by traditional argon arc welding of the end caps.

[0050] The cold fluid channel 201a is connected by flange connecting blocks and bolts. If blockage occurs, the flange connecting blocks can be disassembled and flushed and unblocked with a high-pressure water gun, avoiding the problem of blockage caused by the inability to clean the water side of traditional microchannel heat exchangers and plate heat exchangers.

[0051] Example 2

[0052] Reference Figure 2 and Figure 4-6 This is the second embodiment of the present invention. Unlike the previous embodiment, it also includes a rotating component 401, which includes a drive disk 401a rotatably disposed inside the flange connecting block 102. The drive disk 401a has drive grooves 401b spaced apart on its outer periphery. A cleaning turntable 401c is fixed on one side of the drive disk 401a. A storage tank 401d is spaced apart on the side of the cleaning turntable 401c facing the drive disk 401a. The storage tank 401d is filled with a solvent. A cleaning hole 102d communicating with a storage tank 401d is opened inside the flange connecting block 102. An annular groove is opened on the outer side of the flange connecting block 102 to expose the cleaning turntable 401c. The power component 402 includes a slide rod 402a located above the drive sloping groove 401b. A slider 402b, which slides slidably with the drive sloping groove 401b, is hinged to the bottom of the slide rod 402a. A detection housing 402c is located at the end of the slide rod 402a away from the slider 402b. A detection chamber 402d, communicating with the liquid inlet of the heat exchange assembly 200, is opened in the middle of the detection housing 402c. A piston is slidably connected inside the detection chamber 402d, and when the piston moves, it pushes the slide rod 402a to move. A trigger spring is connected between the piston and the detection housing 402c. Multiple storage tanks 401d have interconnected slots. A sealing component 401d-1 is connected inside each storage tank 401d. A magnetic sheet is located inside the flange connecting block 102 at a position corresponding to the cleaning hole 102d, and the magnetic sheet corresponds to the sealing component 401d-1.

[0053] When fouling occurs inside the heat exchange component 200, it affects water flow, causing an increase in water pressure at the inlet of the heat exchange component 200. When the water pressure exceeds the spring force of the trigger spring, the water pressure pushes the piston to move. The piston then moves the fixedly connected slide rod 402a, which in turn moves the slider 402b. As the slider 402b moves, it drives the drive disc 401a to rotate via the drive groove 401b. In other words, the drive groove 401b is inclined. When the slider 402b passes through the drive groove 401b, it drives the drive disc 401a to rotate to a predetermined position. An angle is set, for example, 10°-25°, and the next drive sloping groove 401b corresponds to the slider 402b. This process is repeated, intermittently driving the drive disc 401a to rotate. The drive disc 401a synchronously drives the cleaning disc 401c to rotate. Therefore, the solvent in the storage tank 401d can be intermittently added to the water through the cleaning hole 102d to dissolve the dirt and achieve a self-cleaning effect. There is no need to frequently disassemble the flange connection block 102. In addition, in conjunction with Embodiment 1, when stubborn dirt is generated inside the heat exchange component 200, the high-pressure water gun can be used for flushing and unblocking.

[0054] In addition, since slider 402b is hinged, when slider 402b moves toward slider 402a, slider 402b contacts drive disk 401a and rotates, so it will not interfere with the reset of slider 402b.

[0055] Furthermore, interconnected slots are provided between multiple storage tanks 401d, and a sealing component 401d-1 is connected inside the storage tank 401d. A magnetic sheet is provided inside the flange connecting block 102 at the position corresponding to the cleaning hole 102d, and the magnetic sheet corresponds to the sealing component 401d-1.

[0056] When the storage tank 401d corresponds to the cleaning hole 102d, the liquid solvent can be mixed in the water. To improve the solvent discharge effect, magnetic sheets are installed around the cleaning hole 102d. These magnetic sheets generate a magnetic attraction to the sealing member 401d-1 in the storage tank 401d, causing the sealing member 401d-1 to deform and squeeze the solvent. This not only accelerates the discharge of the solvent but also allows the sealing member 401d-1 to deform and block the hole, preventing the solvent in the adjacent storage tank 401d from being discharged. The sealing member 401d-1 is made of magnetic material, and an elastic material is fixed between the sealing member 401d-1 and the storage tank 401d, allowing it to deform under stress.

[0057] Multiple storage tanks 401d are connected into one unit through slots, which facilitates the quick addition of solvent. In addition, the outer side of the cleaning turntable 401c has an addition slot that communicates with the storage tanks 401d, which makes it convenient for staff to add solvent.

[0058] Example 3

[0059] Reference Figure 5 and Figure 7 This is the third embodiment of the present invention, which further provides an integrated pressure-bearing microchannel condenser. It includes a cleaning assembly 400 and a pressure relief pipe 411 located above a slide rod 402a. One end of the pressure relief pipe 411 is fixed to the detection housing 402c and communicates with the liquid inlet of the heat exchange assembly 200, while the other end of the pressure relief pipe 411 passes through a flange connecting block 102. A valve plate control rod 412 is rotatably connected below the pressure relief pipe 411, and the top of the valve plate control rod 412 passes through the pressure relief pipe 411. A valve plate is fixed to the portion of the valve plate control rod 412 located within the pressure relief pipe 411, and a torsion spring connected to the pressure relief pipe 411 is sleeved on the outside of the valve plate control rod 412. A limiting block 414, perpendicularly corresponding to the valve plate control rod 412, is fixed to the top of the slide rod 402a. A limiting groove is formed in the middle of the limiting block 414, which is slidably connected to the bottom of the valve plate control rod 412.

[0060] As shown in Example 2, when the internal water pressure of the heat exchange component 200 continues to rise, the slide bar 402a will continue to move, causing the limit block 414 to separate from the valve plate control rod 412, thereby releasing the constraint on the valve plate control rod 412. When the pressure generated by the water pressure is greater than the torque of the torsion spring, the water pressure will open the valve plate, allowing water to be discharged outwards, preventing excessive water pressure from damaging the heat exchange component 200 and extending its service life. As also shown above, when the water pressure at the inlet of the heat exchange component 200 continues to rise, the corresponding sensor will send a warning signal to the operator, prompting them to shut down the equipment in time. If the operator does not observe the warning signal or the sensor malfunctions, the pressure can be released in time through the pressure relief pipe 411 to maintain the corresponding water pressure balance.

[0061] When the valve control rod 412 is located in the limiting groove on the limiting block 414, the valve control rod 412 will be constrained and unable to rotate, thereby preventing water from being discharged outward.
