Description

Technical Field

[0001] This utility model relates to the technical field of brazed plate heat exchangers, specifically a flow-equalizing fast-change brazed plate heat exchanger. Background Technology

[0002] Brazed plate heat exchangers are a new type of high-efficiency heat exchanger made by brazing a series of metal plates with a certain corrugated shape. Thin rectangular channels are formed between the various plates, and heat exchange occurs through the plates.

[0003] The existing system is inconvenient for filtering the air entering and exiting the heat exchange plates, preventing blockage of the corrugated guide channels for the flow of cold / hot media and thus affecting its performance. Utility Model Content

[0004] The purpose of this invention is to provide a flow-equalizing, quick-change brazed plate heat exchanger to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flow-equalizing quick-change brazed plate heat exchanger, comprising a first protective shell and a second protective shell;

[0006] The outer wall of the first protective shell is equipped with a dustproof mechanism, which includes a connecting plate. Both ends of the connecting plate are fixedly connected to filter covers. A plug is fixedly connected to one side of the connecting plate, and the end of the plug is snapped into the outer wall of the first protective shell. A first bolt is threaded onto the outer wall of the connecting plate, and the end of the first bolt extends into the first protective shell.

[0007] Preferably, both the first protective shell and the second protective shell are equipped with a clamping mechanism. The clamping mechanism includes a telescopic rod, the outer wall of which is wound with a spring, and a pressure plate is fixedly connected to the end of the telescopic rod. One end of the telescopic rod is fixedly connected to the inner wall of the first protective shell and the second protective shell, respectively.

[0008] Preferably, the outer wall of the first protective shell has a slot adapted to the insertion rod, and the end of the insertion rod is inserted into the slot. Both the connecting plate and the outer wall of the first protective shell have a first threaded groove adapted to the first bolt.

[0009] Preferably, a refrigerant outlet pipe, a refrigerant inlet pipe, a heat inlet pipe, and a heat outlet pipe are sequentially fixedly connected above the first protective shell.

[0010] Preferably, the outer wall of the first protective shell is threaded with a second bolt, and the end of the second bolt extends into the second protective shell.

[0011] Preferably, a brazed plate heat exchanger body is placed on one side of the pressure plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. With the provided filter cover, connecting plate, insert rod and first bolt, by pushing the connecting plate to move, the connecting plate drives the filter cover and insert rod to move. When the insert rod is inserted into the first protective shell, the filter cover covers the refrigerant outlet pipe, refrigerant inlet pipe, heat inlet pipe and heat outlet pipe respectively. Then, the first bolt is rotated on the connecting plate and enters the first protective shell for fixation, so as to avoid excessive dust during use and blockage, which would affect its performance.

[0014] 2. With the provided telescopic rod, spring, and pressure plate, when the brazed plate heat exchanger body contacts the pressure plate, the pressure plate compresses the telescopic rod, which in turn compresses the spring. The spring generates a reaction force to stretch the spring, which in turn moves the telescopic rod, which in turn pushes the pressure plate to move. The movement of the pressure plate then presses the brazed plate heat exchanger body firmly, preventing it from shaking due to external impacts and affecting its performance.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example

[0021] Please see Figure 1-3 The illustration shows a preferred embodiment of the present technical solution, a flow-equalizing fast-change brazed plate heat exchanger, including a first protective shell 1 and a second protective shell 2.

[0022] A dustproof mechanism 7 is installed on the outer wall of the first protective shell 1. The dustproof mechanism 7 includes a connecting plate 702. Filter covers 701 are fixedly connected to both ends of the connecting plate 702. A plug rod 703 is fixedly connected to one side of the connecting plate 702, and the end of the plug rod 703 is snapped into the outer wall of the first protective shell 1. A first bolt 704 is threadedly connected to the outer wall of the connecting plate 702, and the end of the first bolt 704 extends into the first protective shell 1. By pushing the connecting plate 702 to move, the connecting plate 702 drives the filter cover 701 and the plug rod 703 to move. When the plug rod 703 is inserted into the first protective shell 1, the filter cover 701 covers the refrigerant outlet pipe 3, refrigerant inlet pipe 4, heat inlet pipe 5, and heat outlet pipe 6 respectively. Then, the first bolt 704 is rotated on the connecting plate 702 and enters the first protective shell 1 for fixation, preventing excessive dust from causing blockage during use and affecting its performance.

[0023] like Figure 3 As shown, clamping mechanisms 9 are installed inside both the first protective shell 1 and the second protective shell 2. The clamping mechanism 9 includes a telescopic rod 901, with a spring 902 wound around its outer wall. A pressure plate 903 is fixedly connected to the end of the telescopic rod 901, and one end of the telescopic rod 901 is fixedly connected to the inner wall of the first protective shell 1 and the second protective shell 2 respectively. When the brazed plate heat exchanger body 10 contacts the pressure plate 903, the pressure plate 903 compresses the telescopic rod 901 under force, and the telescopic rod 901 compresses the spring 902 under force. The spring 902 generates a reaction force to stretch the spring 902, and the spring 902 drives the telescopic rod 901 to move. The telescopic rod 901 pushes the pressure plate 903 to move, and the pressure plate 903 moves to press the brazed plate heat exchanger body 10 tightly to prevent it from shaking due to external impact and affecting its performance.

[0024] like Figure 2 As shown, the outer wall of the first protective shell 1 has a slot adapted to the insertion rod 703, and the end of the insertion rod 703 is inserted into the slot. Both the connecting plate 702 and the outer wall of the first protective shell 1 have first threaded grooves adapted to the first bolt 704. The slots on the outer wall of the first protective shell 1 adapted to the insertion rod 703 facilitate the insertion rod 703 to be inserted into the first protective shell 1. The first threaded grooves on the connecting plate 702 and the outer wall of the first protective shell 1 adapted to the first bolt 704 facilitate the first bolt 704 to rotate on the connecting plate 702 and enter into the first protective shell 1 to fix the connecting plate 702.

[0025] like Figure 2As shown, a refrigerant outlet pipe 3, a refrigerant inlet pipe 4, a heat transfer inlet pipe 5, and a heat transfer outlet pipe 6 are sequentially fixedly connected above the first protective shell 1.

[0026] like Figure 1 , 2 As shown in Figure 3, the outer wall of the first protective shell 1 is threaded with a second bolt 8, and the end of the second bolt 8 extends into the second protective shell 2, thereby fixing the first protective shell 1 and the second protective shell 2 together.

[0027] like Figure 3 As shown, a brazed plate heat exchanger body 10 is placed on one side of the pressure plate 903.

[0028] In this embodiment, all components are first installed. During use, when the brazed plate heat exchanger body 10 contacts the pressure plate 903, the pressure plate 903 compresses the telescopic rod 901, which in turn compresses the spring 902. The spring 902 then generates a reaction force to stretch itself, causing the telescopic rod 901 to move. The telescopic rod 901 pushes the pressure plate 903 to move, thus pressing the brazed plate heat exchanger body 10 firmly to prevent damage. If the filter shakes due to an external impact, affecting its performance, the connecting plate 702 is pushed to move. The connecting plate 702 moves the filter cover 701 and the insert rod 703. When the insert rod 703 is inserted into the first protective shell 1, the filter cover 701 covers the refrigerant outlet pipe 3, refrigerant inlet pipe 4, heat inlet pipe 5, and heat outlet pipe 6 respectively. Then, the first bolt 704 is rotated on the connecting plate 702 and enters the first protective shell 1 for fixation, so as to avoid excessive dust clogging during use and affecting its performance.

[0029] The above description provides a further detailed explanation of the present invention in conjunction with specific embodiments. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present invention.
