[0002] A heat exchanger is a device used to transfer heat between two different fluids. It is widely used in various industrial processes to achieve thermodynamic processes such as heating, cooling, evaporation, and condensation. The basic principle of a heat exchanger is to transfer heat through fluid contact and heat exchange, so that the temperature of one fluid increases and the temperature of the other fluid decreases.

[0003] Traditional tube heat exchangers and shell heat exchangers are bulky and require a large installation space, which leads to space waste and difficult layout. Therefore, the inner wall of the tube of traditional tube heat exchangers and shell heat exchangers is prone to scaling and needs to be cleaned and maintained regularly, but cleaning and maintenance inside the tube is difficult and requires a lot of manpower and material resources. Therefore, it is of great significance to study a plate heat exchanger with efficient heat exchange. Utility Model Content

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

DETAILED DESCRIPTION

[0019] 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.

[0020] See also Figure 1-4 The utility model provides a technical solution: a plate heat exchanger with high efficiency in heat exchange, comprising a frame plate 1, a cold outlet flange 2 welded on the front of the frame plate 1, a hot inlet flange 5 welded on the front of the frame plate 1, a hot outlet flange 22 welded on the front of the frame plate 1, a cold inlet flange 21 welded on the front of the frame plate 1, an upper guide rod 6 clamped on the back of the frame plate 1, a lower guide rod 10 clamped on the back of the frame plate 1, a movable pressing plate 13 is clamped on the outer surfaces of the upper guide rod 6 and the lower guide rod 10, a support column 11 is clamped on the outer surfaces of the upper guide rod 6 and the lower guide rod 10, four clamping grooves 17 are opened on the front of the frame plate 1, a plate 20 is clamped on the outer surfaces of the upper guide rod 6 and the lower guide rod 10, and a gasket 19 is fixedly connected to the back of the plate 20.

[0021] Among them, the outer surface of the cold outlet flange 2 is fixedly connected with a first flow meter 3, and the outer surface of the hot inlet flange 5 is fixedly connected with a second flow meter 4. The first flow meter 3 and the second flow meter 4 can monitor the fluid flow entering and leaving the plate heat exchanger in real time, thereby helping the operator to understand the working status and performance of the heat exchanger.

[0022] Among them, the inner walls of the cold outlet flange 2, the hot inlet flange 5, the cold inlet flange 21 and the hot outlet flange 22 are all fixedly connected with an anti-collision plate 14. In the plate heat exchanger, the fluid usually passes through the fluid channel at a high speed, impacting the surface of the plate 20. This impact may cause the plate 20 to deform or be damaged, thereby affecting the heat exchange effect and the service life of the equipment. The anti-collision plate 14 can reduce the impact of the fluid on the plate 20 and protect the plate 20 from damage.

[0023] Among them, a support seat 18 is welded to the bottom surface of the support column 11, a base 15 is welded to the bottom surface of the frame plate 1, and two support feet 16 are welded to the bottom surface of the base 15. The support feet 16 can disperse the weight of the plate heat exchanger to the ground, improve the stability of the equipment, and prevent the equipment from shifting or tipping over during use.

[0024] The back of the movable pressure plate 13 is fixedly connected with a temperature sensor 8, and the temperature sensor 8 can monitor the temperature of the fluid entering and leaving the plate heat exchanger in real time, and help the operator understand the working status and performance of the heat exchanger.

[0025] Among them, the inner wall of each slot 17 is clamped with a limit rod 7, which can limit the movement range of the plate 20 to prevent the plate 20 from shifting or misaligning during the heat exchange process, thereby ensuring that the fluid is evenly distributed between the plates 20. The outer surface of each limit rod 7 is threadedly connected with two first bolts 9.

[0026] Among them, the back side of the support column 11 is threadedly connected with two second bolts 12, and the second bolts 12 can enhance the structural strength of the plate heat exchanger and improve the reliability and stability of the equipment.

[0027] Working principle: When in use, move the device to the place of use, first install the upper guide rod 6 and the lower guide rod 10, clamp the plate 20 between the upper guide rod 6 and the lower guide rod 10, and then use the movable pressure plate 13 to press and ensure it is firm. Connect the hot outlet flange 22, the hot inlet flange 5, the cold outlet flange 2, and the cold inlet flange 21 with the upper water pipeline, let the hot fluid enter from the hot inlet flange 5, and transfer the heat to the plate 20 through the fluid channel. The plate 20 evenly disperses the heat to the entire surface of the plate 20. The cold fluid enters from the cold inlet flange 21, receives the heat from the plate 20, and then takes the heat away through the fluid channel, thereby completing the heat exchange process. The anti-collision plate 14 can reduce the impact of the fluid on the plate 20 and protect the plate 20 from damage.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
