Description

Technical Field

[0001] This utility model relates to the field of heat exchange technology, and in particular to a heat pump coupled heat replenishment device. Background Technology

[0002] In the fields of industrial production and energy utilization, heat exchange devices are widely used as key equipment to heat fluid media to the temperature required by specific processes. The core objective of these devices is to achieve efficient and stable heat transfer in order to meet production needs and save energy.

[0003] To maximize heat exchange efficiency, existing heat exchange devices are typically designed with highly integrated and enclosed structures, using insulation layers or placing the core heat exchange components entirely within a sealed enclosure. The aim is to reduce ineffective heat loss to the external environment during the heat exchange process and transfer as much energy as possible to the target medium, which is highly advantageous during equipment operation.

[0004] However, this superior insulation design has a significant technical drawback after the equipment stops operating. After the reheating operation is completed, a large amount of residual heat will accumulate inside the device, especially in the core heat exchange components. Due to its excellent sealing and insulation properties, this heat cannot be quickly dissipated into the surrounding environment, causing the entire device to remain in a high-temperature state for a long time.

[0005] Sustained high-temperature environments accelerate the thermal aging of various components inside the device. Seals become brittle, pipe materials fatigue due to thermal stress, and the performance of control elements deteriorates, thus significantly shortening the overall service life and reliability of the equipment. Existing technologies have failed to effectively coordinate the two contradictory design requirements of efficient heat replenishment and rapid heat dissipation, and lack a simple and effective integrated structure that can flexibly switch thermal management modes at different operating stages.

[0006] Therefore, this utility model proposes a heat pump coupled heating device to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems in the existing heat pump coupled heating device, which has good heat preservation effect during operation due to its highly enclosed structure, but slow heat dissipation after shutdown, thus causing thermal aging of internal components and affecting the service life of the equipment, this utility model aims to provide a heat pump coupled heating device with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a heat pump coupled heating device, including: a housing, a heating mechanism disposed inside the housing, and a heat dissipation mechanism.

[0009] The heat dissipation mechanism and the heat replenishment mechanism form a cooperative working structure. The heat dissipation mechanism includes a cover plate that is slidably connected to the top of the housing. The opening and closing of the cover plate are used to expose and close the heat replenishment mechanism, respectively, so as to realize the function switching of heat preservation or heat dissipation in different working stages.

[0010] Furthermore, the heat replenishment mechanism includes a partition with at least a hollow structure fixedly connected to the inner wall of the box. A high-temperature liquid delivery pipe and a heat replenishment medium delivery pipe are disposed in the internal cavity of the partition. The cavity of the partition is used to fill the high-temperature liquid to heat the high-temperature liquid delivery pipe and the heat replenishment medium delivery pipe. The heat replenishment mechanism also includes a heat exchange pipe. The outer wall of the heat exchange pipe is fixedly connected to the outer wall of the high-temperature liquid delivery pipe and the outer wall of the heat replenishment medium delivery pipe in sequence to form a coupled heat exchange path. The heat dissipation mechanism also includes a coupling fixedly connected to the top of the cover plate. A hook is rotatably connected to the inner wall of the coupling. A latch is fixedly connected to the front side of the outer wall of the box. The hook and the latch are detachably engaged to lock the cover plate.

[0011] Preferably, the partition has multiple circular holes penetrating its wall thickness, and an aluminum plate is fixedly connected inside the circular holes. To enhance the heat conduction effect, the end of the aluminum plate extends into the cavity of the partition and abuts against the outer wall of the heat transfer medium conveying pipe. This structure utilizes the high thermal conductivity of aluminum to create an efficient shortcut for heat transfer, significantly improving the heat transfer efficiency.

[0012] Preferably, the device further includes a heat replenishing medium storage tank, a high-temperature liquid storage tank, and an auxiliary heat source storage tank. These three storage tanks are arranged side by side on one side of the housing, and their respective output ends are connected to one end of the heat replenishing medium delivery pipe, the high-temperature liquid delivery pipe, and the heat exchange pipe through pipelines, providing a stable and reliable medium source for the continuous operation of the entire heat replenishing system.

[0013] Preferably, to maximize heat exchange efficiency, the heat exchange tube is fixed sequentially to the outer wall of the high-temperature liquid conveying pipe and the outer wall of the heat replenishing medium conveying pipe in a spiral winding manner. This tight spiral winding structure not only greatly increases the effective contact surface area between the heat exchange tube and the two conveying pipes, but also correspondingly extends the flow heat exchange time of the auxiliary heat source liquid on the outer wall of the pipe, thereby achieving a more thorough heat exchange.

[0014] Preferably, to facilitate user operation, a handle is fixedly connected to the top of the cover plate. The handle provides a clear and ergonomic point of force application, making it convenient for users to apply pulling force to slide open or close the cover plate, greatly improving the human-computer interaction friendliness and ease of operation of the device.

[0015] Preferably, in order to make the locking state of the cover plate more stable and reliable, there are two couplings and two hooks, which are symmetrically arranged on the top of the cover plate. There are also two latches, which are fixed to the outer wall of the box body in correspondence with the position of the hooks. This symmetrical locking system can make the locking force evenly distributed on the cover plate, effectively preventing loosening or deformation problems that may be caused by uneven force on one side.

[0016] Preferably, in order to improve the overall heat exchange capacity and throughput of the device, there are multiple partitions, and the multiple partitions are arranged in parallel and spaced along the length of the box. The high-temperature liquid delivery pipe and the heat replenishment medium delivery pipe pass through all the partitions in sequence. This design expands a single heat exchange unit into a large-scale array heat exchange structure, thereby achieving a multiple increase in heat exchange area.

[0017] This utility model has the following beneficial effects: 1. This utility model, by setting a hollow partition, and setting a high-temperature liquid conveying pipe, a heat replenishing medium conveying pipe and a heat exchange pipe wound around the outer wall of the two pipes in sequence inside the partition, forms a coupled heat exchange path. At the same time, the aluminum plate inserted into the partition enhances the heat conduction, which solves the problems of multiple heat transfer links, large losses and low heat replenishing efficiency in the existing heat replenishing device, and achieves the technical effects of heat cascade utilization, efficient conduction and improved overall heat replenishing efficiency. 2. This utility model, by setting a sliding cover plate on the top of the box and using a locking device composed of a coupling, hooks and latches, allows the cover plate to be easily opened after use, so that the core heating components of the internal partition are fully exposed to the external environment. This solves the problem in the prior art that after the use of the heating device, the internal heat accumulates and is difficult to dissipate quickly, which leads to accelerated aging of internal components and shortened service life. It achieves the technical effect of simple structure, convenient operation, and rapid heat dissipation after use, thus protecting the equipment. 3. This utility model combines the core heating component partition of the heating mechanism with the opening and exposure function of the heat dissipation mechanism, organically unifying the two core functions of heating and heat dissipation in a clever structural design. This solves the problem of complex structure and poor overall integrity caused by the implementation of different functions in the prior art, and achieves the technical effect of compact structure, ingenious design, multi-purpose function, and significantly improved practicality and durability of the device.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Example: Please refer to Figures 1 to 6 This utility model provides a heat pump coupled heating device, which aims to solve the problems of large heat loss during the transfer process and slow dissipation of internal residual heat after the equipment is stopped in the prior art.

[0022] like Figure 1 , Figure 4 and Figure 5As shown, a heat pump coupled heating device includes a housing 1, with a heating mechanism 2 installed inside the housing 1 and a heat dissipation mechanism 3 installed outside the housing 1. The housing 1 serves as the mounting platform for the entire device. The heating mechanism 2 is used for efficient heating of the medium, and the heat dissipation mechanism 3 is used for rapid cooling of the heating mechanism 2 after the device stops working. The heat dissipation mechanism 3 includes a cover plate 301 slidably connected to the top of the housing 1. The opening and closing of the cover plate 301 correspond to the exposed and closed states of the heating mechanism 2, respectively. A handle 304 is fixedly connected to the top. By pulling the handle 304, the cover plate 301 can slide along the top of the box 1. In order to lock the cover plate 301 in the closed position, a coupling 302 is also fixedly connected to the top of the cover plate 301. A hook 303 is rotatably connected to the inner wall of the coupling 302. A latch 305 is fixedly connected to the front side of the outer wall of the box 1 and is detachably engaged with the hook 303. By rotating the hook 303 to engage or disengage with the latch 305, the cover plate 301 can be locked or unlocked.

[0023] like Figure 2 and Figure 4 As shown, the structure of the heat exchange mechanism 2 is a partition 201 with at least a hollow structure fixedly connected to the inner wall of the housing 1. The interior of the partition 201 forms a sealed cavity. In the inner cavity of the partition 201, a high-temperature liquid conveying pipe 205 and a heat exchange medium conveying pipe 204 are arranged side by side. The inner cavity of the partition 201 is used to fill the high-temperature liquid to heat the high-temperature liquid conveying pipe 205 and the heat exchange medium conveying pipe 204, thereby forming a basic heat exchange environment. Furthermore, the heat exchange mechanism 2 also includes a heat exchange pipe 209 for realizing coupled heat exchange. The outer wall of the heat exchange pipe 209 is fixedly connected to the outer wall of the high-temperature liquid conveying pipe 205 and the outer wall of the heat exchange medium conveying pipe 204 in sequence. The structure allows the liquid flowing out from the auxiliary heat source to first exchange heat with the high-temperature liquid conveying pipe 205, and after being heated, it continues to flow through and exchange heat with the heat exchange medium conveying pipe 204 for a second time, thereby forming an efficient coupled heat exchange path.

[0024] Please refer to Figure 3 and Figure 4 The partition 201 has multiple circular holes 202 penetrating its wall thickness. An aluminum plate 203 is fixedly connected inside each circular hole 202. The aluminum plate 203 is designed to utilize its excellent thermal conductivity to create an efficient "thermal bridge" for heat transfer. Specifically, the end of the aluminum plate 203 extends into the cavity of the partition 201 and abuts against the outer wall of the heat replenishing medium conveying pipe 204. This structure allows the heat carried by the high-temperature liquid filling the cavity of the partition 201 to be quickly and directly conducted to the outer wall of the heat replenishing medium conveying pipe 204 through the wall of the partition 201 and then through the highly thermally conductive aluminum plate 203. This significantly reduces the thermal resistance during heat transfer and greatly improves the heat replenishment efficiency of the medium inside the pipe.

[0025] Meanwhile, in order to ensure the continuous operation of the entire heat replenishment system, the device also includes a heat replenishment medium storage tank 206, a high-temperature liquid storage tank 207, and an auxiliary heat source storage tank 208. These three storage tanks are arranged side by side on one side of the housing 1. One end of the heat replenishment medium delivery pipe 204 is connected to the heat replenishment medium storage tank 206 through a pipeline to supply the medium that needs to be heated. One end of the high-temperature liquid delivery pipe 205 is connected to the high-temperature liquid storage tank 207 through a pipeline to deliver high-temperature liquid into the cavity of the partition 201. One end of the heat exchange pipe 209 is connected to the auxiliary heat source storage tank 208 through a pipeline to provide auxiliary heat source liquid for coupled heat exchange.

[0026] As a preferred embodiment, please refer to Figure 4 In order to increase the overall heat exchange area and processing capacity of the device, there are multiple partitions 201, and the multiple partitions 201 are arranged in parallel and spaced along the length of the box 1 to form an extended heat exchange area. The high temperature liquid conveying pipe 205 and the heat replenishing medium conveying pipe 204 pass through all the partitions 201 in sequence to ensure that the medium can be uniformly and fully replenished in the entire box 1.

[0027] As another preferred implementation, such as Figure 2 As shown, in order to maximize the contact area and efficiency of coupled heat exchange, the heat exchange tube 209 is tightly fixed to the outer wall of the high-temperature liquid conveying pipe 205 and the outer wall of the heat replenishing medium conveying pipe 204 in a spiral winding manner. This tight spiral winding structure not only increases the contact area between the heat exchange tube 209 and the two conveying pipes, but also extends the flow path of the auxiliary heat source liquid on the outer wall of the pipe, thereby achieving more complete heat exchange.

[0028] As a preferred design for the heat dissipation mechanism 3, please refer to Figure 1 and Figure 5 To ensure that the cover plate 301 can be locked stably and symmetrically, there are two couplings 302 and two hooks 303, which are symmetrically arranged on the top of the cover plate 301. Correspondingly, there are also two latches 305, which are fixed to the outer wall of the housing 1 in correspondence with the positions of the two hooks 303. This symmetrical locking structure can make the locking force evenly distributed and prevent the cover plate 301 from deforming or loosening on one side during long-term use.

[0029] As a preferred solution that is easy to operate, such as Figure 1 and Figure 5 As shown, a handle 304 is also fixedly connected to the top of the cover plate 301. The handle 304 provides a clear force point, making it convenient for users to apply pulling force to slide open or close the cover plate 301, thus improving the ease of operation.

[0030] Working principle: When the medium is reheated, the high-temperature liquid in the high-temperature liquid storage tank 207 is transported through the high-temperature liquid delivery pipe 205 fixedly connected to the outer wall to the inner wall of multiple partitions 201 fixedly connected to the inner wall of the tank 1. The medium inside the reheating medium storage tank 206 is transported through the reheating medium delivery pipe 204 fixedly connected to the outer wall of the partition 201 for circulation. Since the heat exchange pipe 209 is fixedly connected to the outer wall of the high-temperature liquid delivery pipe 205 and the reheating medium delivery pipe 204, the auxiliary heat source storage tank 208 sends its internal liquid to the outer wall of the high-temperature liquid delivery pipe 205 through the fixedly connected heat exchange pipe 209 for the first coupling heat exchange. After the heat exchange, the liquid flows along the heat exchange pipe. 209 delivers the heat-exchanged liquid to the outer wall of the heat-replenishing medium conveying pipe 204, allowing the heat-exchanged liquid and the medium to undergo a second coupled heat exchange. The aluminum plate 203 is fixedly connected to the inside of the multiple round holes 202 opened in the partition 201, so that the high-temperature liquid on the inner wall of the partition 201 has better thermal conductivity. When the medium flows, it is reheated by the high-temperature liquid on the inner wall of the partition 201 on the outer wall of the pipe, so that the medium reaches the required temperature. It then proceeds to the next step through the right side of the heat-replenishing medium conveying pipe 204. After the high-temperature liquid cools down, it is discharged through the right side of the high-temperature liquid conveying pipe 205. The cooperation between the box 1 and the heat-replenishing mechanism 2 solves the problem of how much temperature is lost during the transmission process in the prior art. Furthermore, after the reheating stops, since both hooks 303 are rotatably connected to the inner walls of the two couplings 302, and the two couplings 302 are fixedly connected to the top of the cover plate 301, the two hooks 303 are rotated through the two couplings 302, causing the two hooks 303 to separate from the two latches 305 fixedly connected to the front side of the outer wall of the box 1. Since the cover plate 301 is slidably connected to the top of the box 1, by pulling the handle 304 fixedly connected to the top of the cover plate 301, the cover plate 301 is moved, exposing the multiple partitions 201 inside the box 1 to the outside. The partitions 201 are then cooled by the external temperature. The heat dissipation mechanism 3 solves the problem that the heat dissipation inside the box 1 is slow after use in the prior art, which indirectly reduces the service life of the internal components of the box 1.
