Description

Technical Field

[0001] This utility model relates to the field of heat exchangers, and in particular to a corrugated plate condensing heat exchanger. Background Technology

[0002] A plate heat exchanger is a new type of high-efficiency heat exchanger composed of a series of metal plates with a specific corrugated shape. Thin rectangular channels are formed between the plates, through which heat exchange occurs. Plate heat exchangers are ideal devices for liquid-liquid and liquid-vapor heat exchange. They feature high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, easy installation and cleaning, wide application, and long service life.

[0003] The existing corrugated plate condensing heat exchanger requires multiple corrugated metal sheets to be stacked and pressed together during installation and use. Then, multiple fastening bolts and screws are used to fix and lock the fastening plate. However, during the tightening process, external force is required to keep the multiple metal sheets pressed together and prevent them from misaligning and falling off, making the overall installation process quite troublesome.

[0004] Therefore, it is necessary to provide a new corrugated plate condensing heat exchanger to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a corrugated plate condensing heat exchanger.

[0006] This utility model provides a corrugated plate condensing heat exchanger comprising: a base, with side frames fixedly connected to both ends of the base, a beam frame fixedly connected to the top of the two side frames, multiple corrugated pipe plates on the base, multiple water exchange ports on one end of the side frame, and a fastening plate on the base; a convenient pre-tightening mechanism, comprising a preset pressure plate located on one side of the fastening plate, with positioning rods fixedly connected to both ends of the preset pressure plate, two symmetrically positioned side cylinders on the side wall of the other end of the side frame, each of the two positioning side cylinders having an insertion port, the two positioning rods being slidably connected to the insertion ports on the two positioning side cylinders respectively, each of the two positioning rods having a slot, and a secondary cylinder fixedly connected to each of the two positioning side cylinders.

[0007] Preferably, an embedded groove is provided on one side wall of the fastening plate, the embedded groove is aligned with the preset pressure plate, and two limiting rods are symmetrically provided between the two side frames, with the two ends of the preset pressure plate slidably connected to the two limiting rods respectively.

[0008] Preferably, each of the two positioning side cylinders has a through-hole on its wall, the two auxiliary cylinders are aligned with the two through-holes respectively, and the interior of each of the two auxiliary cylinders is provided with a locking component.

[0009] Preferably, the locking assembly includes a stop rod, which is slidably connected to one end of the secondary cylinder wall. A locking head is fixedly connected to one end of the stop rod. An internal disc is provided inside the secondary cylinder, which is fixedly connected to the stop rod. A spring is sleeved on the stop rod, with one end of the spring connected to the internal disc and the other end of the spring connected to the inner wall of the secondary cylinder.

[0010] Preferably, a pull plate is fixedly connected to the other end of the abutment rod.

[0011] Preferably, multiple crossbars are symmetrically fixedly connected between the two side frames, and multiple sliding holes are provided on the fastening plate. The fastening plate is slidably connected to the multiple crossbars, and each of the multiple crossbars is a threaded rod, with fastening bolts installed on each of the multiple crossbars.

[0012] Compared with related technologies, the corrugated plate condensing heat exchanger provided by this utility model has the following beneficial effects:

[0013] 1. This utility model uses a sliding preset pressure plate to make its two ends slide stably relative to two limiting rods. The preset pressure plate drives the two positioning rods at its two ends to move closer to the insertion ports of the two positioning side cylinders. At the same time, the preset pressure plate slides and presses against multiple corrugated pipe plates. The preset pressure plate is used to pre-press multiple corrugated pipe plates, which facilitates subsequent locking and installation. It is very convenient.

[0014] 2. This utility model uses a preset pressure plate to move two positioning rods at both ends into the slots of two positioning side cylinders. When one end of the two positioning rods abuts against the inclined surface of one end of the clamp, the two clamps drive the two abutment rods to slide back, causing both springs to undergo elastic deformation. When the two clamps move to the slots on the two positioning rods and align with each other, the two springs restore their elastic deformation, causing the two abutment rods to drive the two clamps to reset and enter the two slots, automatically completing the locking of the two positioning rods.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figures 1 to 3 A corrugated plate condensing heat exchanger includes: a base 1, with side frames 11 fixedly connected to both ends of the base 1, and a beam frame 12 fixedly connected to the top of the two side frames 11. Multiple corrugated pipe plates 2 are provided on the base 1, and multiple water inlets 3 are provided on one side frame 11. A fastening plate 4 is provided on the base 1. A convenient pre-tightening mechanism includes a preset pressure plate 5, which is located on one side of the fastening plate 4. Positioning rods 51 are fixedly connected to both ends of the preset pressure plate 5. Two positioning side cylinders 52 are symmetrically arranged on the side wall of the other side frame 11. Each positioning side cylinder 52 has an insertion port. The two positioning rods 51 are slidably connected to the insertion ports on the two positioning side cylinders 52, and each positioning rod 51 has a slot. A secondary cylinder 53 is fixedly connected to each of the two positioning side cylinders 52.

[0021] In the specific implementation process, such as Figure 1 and Figure 2 As shown, an embedded groove is provided on one side wall of the fastening plate 4, which is aligned with the preset pressure plate 5. Two limiting rods 6 are symmetrically provided between the two side frames 11, and the two ends of the preset pressure plate 5 are slidably connected to the two limiting rods 6 respectively.

[0022] It should be noted that: the sliding preset pressure plate 5 makes its two ends slide stably relative to the two limit rods 6. The preset pressure plate 5 drives the two positioning rods 51 at its two ends to move closer to the insertion ports of the two positioning side cylinders 52. The preset pressure plate 5 is used to pre-press the multiple corrugated pipe plates 2, which facilitates the subsequent locking installation.

[0023] When the fastening plate 4 moves to abut against the preset pressure plate 5, the preset pressure plate 5 moves back into the recessed groove in the fastening plate 4, so that it can automatically assemble into an integrated fastener after installation.

[0024] refer to Figure 1 As shown, each of the two positioning side cylinders 52 has a through-hole on its cylinder wall, and the two auxiliary cylinders 53 are aligned with the two through-holes respectively. Each of the two auxiliary cylinders 53 has a locking component inside.

[0025] refer to Figure 1 and Figure 2 As shown, the locking assembly includes a stop rod 7, which is slidably connected to one end of the secondary cylinder 53. A locking head 71 is fixedly connected to one end of the stop rod 7. An internal disc 72 is provided inside the secondary cylinder 53, which is fixedly connected to the stop rod 7. A spring 73 is sleeved on the stop rod 7. One end of the spring 73 is connected to the internal disc 72, and the other end of the spring 73 is connected to the inner wall of the secondary cylinder 53.

[0026] It should be noted that when one end of the two positioning rods 51 abuts against the inclined surface of one end of the clamp 71, the two clamps 71 drive the two abutment rods 7 to slide back, causing the two springs 73 to undergo elastic deformation.

[0027] When the two locking heads 71 ​​move to align with the slots on the two positioning rods 51, the two springs 73 restore their elastic deformation, causing the two abutments 7 to drive the two locking heads 71 ​​to reset and enter the two slots, automatically completing the locking of the two positioning rods 51.

[0028] refer to Figure 1 As shown, the other end of the abutment 7 is fixedly connected to a pull plate 74.

[0029] It should be noted that the pull plate 74 is designed to pull out the stop rod 7, which can easily release the lock on the two positioning rods 51.

[0030] refer to Figure 1 and Figure 3 As shown, multiple crossbars 8 are symmetrically fixedly connected between the two side frames 11. Multiple sliding holes are provided on the fastening plate 4. The fastening plate 4 is slidably connected to the multiple crossbars 8. All the crossbars 8 are screw rods, and fastening bolts 81 are installed on the multiple crossbars 8.

[0031] It should be noted that by screwing in multiple fastening bolts 81 in sequence, the fastening plate 4 can be fixed.

[0032] The working principle of the corrugated plate condensing heat exchanger provided by this utility model is as follows: Multiple corrugated pipe plates 2 are stacked and pressed together in sequence. A sliding preset pressure plate 5 is used to make its two ends slide stably relative to two limiting rods 6. The preset pressure plate 5 drives the two positioning rods 51 at its two ends to move closer to the insertion ports of the two positioning side cylinders 52. At the same time, the preset pressure plate 5 slides and presses against the multiple corrugated pipe plates 2. When one end of the two positioning rods 51 abuts against the inclined surface of one end of the clamp 71, the two clamps 71 drive the two abutment rods 7 to slide back, causing the two springs 73 to undergo elastic deformation. When the two clamps 71 move to the slots on the two positioning rods 51 and align with each other, the two springs 73 restore their elastic deformation, causing the two abutment rods 7 to drive the two clamps 71 to reset and enter the two slots, automatically completing the locking of the two positioning rods 51. The preset pressure plate 5 completes the pre-pressing of multiple corrugated pipe plates 2, which is convenient for subsequent locking and installation.
