[0002] Geothermal heat pump system, also known as ground source heat pump, uses ground energy, soil, groundwater, surface water, low-temperature geothermal water and tail water as the cooling source for heat pump cooling in summer and the low-temperature heat source for heating in winter. It is also a system for achieving heating, cooling and domestic hot water. It is used to replace the traditional mode of using refrigerators and boilers for air conditioning, heating and heating. It is an effective way to improve the urban atmospheric environment and save energy. It is also a new development direction for domestic ground source energy utilization.

[0003] The existing ground source heat pump heat exchanger has a clamping plate that can only be in use on one side, while the other side is idle, resulting in low utilization of the clamping plate and low heat exchange efficiency of the ground source heat pump heat exchanger. Summary of the Invention

The plywood assembly includes a double-sided plywood, and a frame gap is opened in the middle of the front and rear frames of the double-sided plywood. A rubber sealing frame is embedded in the inner side of the frame gap, and a memory alloy frame is embedded in the interlayer between the rubber sealing frame and the frame gap. When heated, it can expand forward and backward along the radial depth direction of the frame gap. A transducer is installed in the middle of the inner wall frame of the double-sided plywood;

[0006] A front panel is installed at the front end of the double-sided plywood and is used for heat exchange with ground source heat. A rear panel is installed at the rear end of the double-sided plywood and is installed symmetrically with the front panel. The front panel and the rear panel have the same structure, which can effectively utilize the back side of the double-sided plywood.

[0007] Preferably, the outer surface of the memory alloy frame is penetrated by deformation grooves arranged in a ring shape, and a convex corner is provided in the middle of the curved wall of the deformation groove, which is used to cooperate with the deformation groove to provide a shrinkage space for the cooling and rebound of the memory alloy frame, and is connected to the inner wall surface of the memory alloy frame.

[0008] Preferably, connecting parts are provided at both ends of the deformation groove and connected to the inner wall of the memory alloy frame, which perform tensioning and limiting on the two ends of the deformation groove to prevent excessive deformation and help the memory alloy frame to rebound to its initial state after cooling.

DETAILED DESCRIPTION

[0028] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0029] The first embodiment, as Figures 1 to 9 As shown, the present invention provides a technical solution: a ground source heat pump heat exchanger, comprising a shell plate 1, wherein flange pipes 2 are installed at the front and rear corners of the shell plate 1;

[0030] The housing further comprises a plywood assembly 3, which is stacked and assembled on the inner side of the outer shell 1 for heat exchange with ground source heat. The plywood assembly 3 comprises a double-sided plywood 31, and a frame gap 34 is formed in the middle of the front and rear frames of the double-sided plywood 31. A rubber sealing frame 32 is embedded in the inner side of the frame gap 34, and a memory alloy frame 35 is embedded in the interlayer between the rubber sealing frame 32 and the frame gap 34. When heated, the memory alloy frame 35 can expand forward and backward along the radial depth direction of the frame gap 34. A transducer 33 is installed in the middle of the inner wall frame of the double-sided plywood 31.

[0031] The front panel 4 is installed at the front end of the double-sided plywood 31 and is used for heat exchange with ground source heat. The rear end of the double-sided plywood 31 is installed with a rear panel 5, which is installed symmetrically with the front panel 4, and the front panel 4 and the rear panel 5 have the same structure.

[0032] The outer surface of the memory alloy frame 35 is penetrated by a ring-shaped deformation groove 36. A convex corner 37 is provided in the middle of the curved wall of the deformation groove 36 to cooperate with the deformation groove 36 to provide a shrinkage space for the cooling and rebound of the memory alloy frame 35, and is connected to the inner wall surface of the memory alloy frame 35.

[0033] Both ends of the deformation groove 36 are provided with connecting parts 38, which are connected to the inner wall of the shape memory alloy frame 35.

[0034] During use, the two end parts of the deformation groove 36 are tension-limited through the connecting parts 38 to prevent excessive deformation of the main body of the shape memory alloy frame 35. At the same time, it helps the shape memory alloy frame 35 to automatically rebound to the initial state after cooling; by using the shape memory alloy frame 35 to expand and deform when heated, one side of the rubber sealing frame 32 close to the double-sided splint 31 or the outer shell plate 1 can be extruded, making the installation between the structures more closely fitted. When the heat exchanger exchanges heat, the structure between the splint components is compact, light and flexible, reducing heat loss and having high heat exchange efficiency.

[0035] It can effectively utilize the back of the double-sided splint 31. Through the symmetrical installation of the front plate member 4 and the rear plate member 5 on the front and back sides of the double-sided splint 31, the heat exchange efficiency between liquids can be doubled.

[0036] Second embodiment, on the basis of the first embodiment, please refer to Figures 5 to 8 As shown, the front plate member 4 includes a main plate piece 41 installed at the front end of the double-sided splint 31. One side of the main plate piece 41 is connected with a first sub-plate piece 42, and the other side is connected with a second sub-plate piece 43. And a wide slot 44 is opened in the middle of the side of the main plate piece 41 away from the double-sided splint 31; guide bars 45 are installed in a linear array on the inner sides of the first sub-plate piece 42 and the second sub-plate piece 43, and are arranged in an inclined shape to increase the contact area and improve the heat conduction efficiency; auxiliary rib members 46 are installed at equal intervals on the inner side of the wide slot 44, and are arranged close to the short side edge of the main plate piece 41. Main rib members 47 are installed at equal intervals on the inner side of the wide slot 44, and are arranged close to the long side edge of the main plate piece 41.

[0037] A return belt 48 is connected to the long side edge of the main plate piece 41, and is installed inside the wide slot 44 and located between the main rib member 47 and the long side edge of the main plate piece 41. A spring 49 is connected to the middle of the long side edge of the main plate piece 41, and the other end is connected to the middle of the return belt 48. Edge cavities 410 are left between the two ends of the auxiliary rib members 46 and the main rib members 47 and the curved side edges of the main plate piece 41 respectively, facilitating the autonomous flow of the heat conduction medium at the edge of the wide slot 44, so that the heat conduction medium inside the wide slot 44 will not be isolated from each other due to the installed auxiliary rib members 46 and main rib members 47, improving the overall heat exchange effect of the heat conduction medium itself. A metal groove film 411 is installed in a spiral shape on the side of the main plate piece 41 facing the double-sided splint 31.

[0038] The main reinforcement member 47 includes a main reinforcement rod 471, which is integrally in a curved bow shape. Both ends of the main reinforcement rod 471 are fixedly connected with joints 472, and the joints 472 are connected to the curved edge of the main board piece 41. On the side of the surface of the main reinforcement rod 471 close to the open slot 44, a first web belt 473 is connected. On the side of the surface of the main reinforcement rod 471 far from the open slot 44, a second web belt 474 is connected. And through holes 475 are evenly spaced on the surfaces of the first web belt 473 and the second web belt 474.

[0039] In the middle of the surface of the main reinforcement rod 471, a diameter rod 476 is fixedly inserted. On the outer surface of the diameter rod 476, retaining plates 477 are installed at equal intervals, and are symmetrically installed on the front and back sides of the main reinforcement rod 471. One main reinforcement member 47 or auxiliary reinforcement member 46 corresponds to the middle of every two groups of retaining plates 477. The main structure of the auxiliary reinforcement member 46 is the same as that of the main reinforcement member 47. The difference is that the main body of the auxiliary reinforcement rod in the middle of the auxiliary reinforcement member 46 is in a wavy shape. One end of the diameter rod 476 passes through the elastic return belt 48 and is inserted into the long edge of the main board piece 41 through a spring 49, and is elastically installed with the long edge of the main board piece 41 under the cooperation of the spring 49 and the elastic return belt 48.

[0040] The other end of the diameter rod 476 passes through the main reinforcement member 47 and the auxiliary reinforcement member 46 and is connected to the output end of the transducer 33, and the output end of the transducer 33 is exposed inside the open slot 44; large through holes are penetrated at the corners of the main board piece 41, the first auxiliary board piece 42 and the second auxiliary board piece 43.

[0041] During use, the transducer 33 can drive the main reinforcement member 47 and the auxiliary reinforcement member 46 to jointly perform acoustic vibration on the heat-conducting medium, improve the activity and fluidity of the heat-conducting medium inside the open slot 44, and improve the heat exchange efficiency. By starting the transducer 33, while activating the heat-conducting medium to improve the activity and fluidity of the heat-conducting medium inside the open slot 44, it can drive the auxiliary reinforcement member 46 and the main reinforcement member 47 to oscillate inside the open slot 44. Under the overall swing of the heat-conducting medium jointly by the first web belt 473 and the second web belt 474, the flow rate and activity intensity of the internal heat-conducting medium are accelerated, further improving the heat conduction efficiency of the heat-conducting medium and the overall heat conduction efficiency of the heat exchanger, and improving the practicability.

[0042] Under the cross-flow action of the through holes 475 and the edge cavity 410, the heat-conducting medium inside the open slot 44 will not show the phenomenon of local stagnation and being fixed in one place, ensuring the overall high-efficiency heat exchange function of the front plate member 4 for the ground source heat; and by continuously oscillating the heat-conducting medium, it can effectively avoid the precipitation of foreign matters that may exist in the heat-conducting medium, ensuring that the inside of the open slot 44 will not be blocked.

[0043] The flange nozzle 2 can be installed on the outer shell plate 1 through the large through hole by passing through the front plate member 4, providing a guiding path and direction for the heat exchange between liquids, and making the heat exchange between liquids more rapid and fast under the combined use of the front plate member 4 and the rear plate member 5.

[0044] It is possible to utilize the flow of the heat conduction medium inside the open tank 44 and the agitating action of the transducer 33 to further generate a local resonance effect on the heat conduction medium through the metal tank film 411, and enhance the thermal energy of the heat conduction medium itself through the oscillating action, so as to assist in increasing the heat exchange effect of the heat exchanger.

[0045] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art and related fields based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention shall be implemented by conventional means in the art without special instructions and limitations.
