[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides a heat insulation device for a plate heat exchanger, such as Figure 1-Figure 4 As shown, it includes a heat insulation cover 2, which is a U-shaped plate structure. The heat insulation cover 2 covers the outside of the plate heat exchanger 1, the open side of the heat insulation cover 2 is located on the front of the plate heat exchanger 1, and the closed side is located on the back of the plate heat exchanger 1. A flip cover 4 is installed on the top of the heat insulation cover 2, and the plate heat exchanger 1 is isolated from the outside space by the heat insulation cover to avoid the loss of the side wall of the plate heat exchanger 1 and improve the heat exchange efficiency of the service heat exchanger 1. A plurality of locking components 3 are installed on the side of the heat insulation cover 2, and the locking components 3 include a pressing plate 31, and a threaded rod 32 is installed on the back of the pressing plate 31. A groove 21 is provided on the inner side of the heat insulation cover 2, and a threaded hole 22 is provided in the middle of the inner part of the groove 21. The threaded hole 22 is threadedly connected with the threaded rod 32, and the heat insulation cover 2 is conveniently locked on the plate heat exchanger 1 through the locking components 3, and it is convenient to disassemble.

[0025] In this embodiment, one side of the flip cover 4 is rotatably connected to the top of the heat insulation cover 2 via a hinge, so that the flip cover 4 can be opened and closed easily.

[0026] Specifically, the size of the groove 21 matches that of the pressing plate 31 , ensuring that the pressing plate 31 is positioned in the groove 21 without deviation.

[0027] Furthermore, a handle 33 is installed at the outer end of the threaded rod 32 to facilitate the operation of screwing the threaded rod 32 .

[0028] Furthermore, the heat insulation cover 2 is divided into three layers from the inside to the outside, the inner layer is a flexible layer 23, the middle layer is a heat insulation layer 24, and the outer layer is a protective layer 25. The flexible layer 23 is used to protect the plate heat exchanger 1 from wear, the heat insulation layer 24 has a good heat insulation effect, and the protective layer 25 has a protective effect to avoid external collision or extrusion.

[0029] Furthermore, the flexible layer 23 is made of silicone material, the heat insulating layer 24 is made of ceramic fiber material, and the protective layer 25 is made of stainless steel material.

[0030] Furthermore, a sealing strip 41 is installed on the bottom side of the flip cover 4 to ensure the sealing performance after the flip cover 4 is closed.

[0031] Furthermore, the flexible layer 23 , the heat insulating layer 24 and the protective layer 25 are bonded to each other through waterproof glue to ensure that the flexible layer 23 , the heat insulating layer 24 and the protective layer 25 are connected and fixed.

[0032] When the heat insulation device for a plate heat exchanger of the utility model is used, firstly, the opening side of the heat insulation cover 2 is aligned with the front side of the plate heat exchanger 1, and the closed side is pressed against the back side of the plate heat exchanger 1, ensuring that the heat insulation cover 2 is tightly fitted to the side wall of the plate heat exchanger 1.

[0033] Then, the locking assembly 3 is installed on the side of the heat shield 2. The pressing plate 31 of the locking assembly 3 matches the size of the groove 21 inside the heat shield 2, and the pressing plate 31 is placed in the groove 21 and is threadedly connected to the threaded hole 22 inside the groove 21 through the threaded rod 32. By rotating the handle 33 at the outer end of the threaded rod 32, the pressing plate 31 can be easily fixed in the groove 21, so that the heat shield 2 is locked on the plate heat exchanger 1.

[0034] Next, close the flip cover 4. The flip cover 4 is rotatably connected to the top of the heat insulation cover 2 through a hinge, so that the user can easily open or close it. When the flip cover 4 is closed, the sealing strip 41 on the bottom side can ensure good sealing and prevent heat from being lost through the top.

[0035] The three-layer structure of the heat insulation cover 2 plays a key role. The inner flexible layer 23 (made of silicone material) is tightly attached to the outer side of the plate heat exchanger 1, providing protection and buffering to prevent the plate heat exchanger 1 from being worn. The middle insulation layer 24 (made of ceramic fiber material) is the core part of the insulation device, which can effectively isolate the transfer of heat and reduce the heat loss of the side wall of the plate heat exchanger 1, thereby improving the heat exchange efficiency. The outer protective layer 25 (made of stainless steel material) provides solid protection, can resist external collision or extrusion, and protect the insulation layer 24 from damage. The flexible layer 23, the insulation layer 24 and the protective layer 25 are bonded to each other by waterproof glue, which ensures that the connection between the layers is firm, and also prevents moisture penetration, further enhancing the insulation effect.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
