Description

Technical Field

[0002] As an efficient and compact heat exchange device, the plate heat exchanger is widely used in industries, buildings, food processing and other fields. Its core technology lies in achieving heat transfer between hot and cold fluids by the close contact between multiple heat conduction plates. This heat exchange unit adopts a design concept convenient for cleaning. By setting a left clamping plate and a right clamping plate of the unit, and arranging multiple heat conduction plates therebetween, these plates are closely attached to ensure effective heat transfer. The unit realizes the stable fixation of the plates through the combination of clamping plate connecting screws and fixing nuts. At the same time, the setting of the support bottom plate and the installation fixing plate provides a stable support and installation method. The introduction of U-shaped heat medium pipes and U-shaped refrigerant pipes enables the heat medium and the refrigerant to fully exchange heat outside the heat conduction plates, and the setting of externally connected flanges at the pipe orifices simplifies the pipeline connection process and improves the installation convenience of the equipment. The overall design not only meets the requirements of efficient heat exchange, but is also easy to maintain and clean, and is applicable to a variety of application scenarios.

The plurality of heat conduction plates 4 are mutually attached. A plurality of clamping plate connecting screws 3 are equidistantly connected between the front and rear ends and the top end of the left clamping plate 2 of the unit and the right clamping plate 5 of the unit. Fixing nuts 8 are externally threaded on the left and right ends of the plurality of clamping plate connecting screws 3. The plurality of clamping plate connecting screws 3 are fixedly connected to the left clamping plate 2 of the unit and the right clamping plate 5 of the unit through the fixing nuts 8. A support bottom plate 12 is connected between the bottom ends of the left clamping plate 2 of the unit and the right clamping plate 5 of the unit. Installation fixing plates 11 are welded to the left end of the bottom of the left clamping plate 2 of the unit and the right end of the bottom of the right clamping plate 5 of the unit. A plurality of installation screw holes are arranged inside the installation fixing plates 11. A U-shaped heat medium pipe 6 is arranged on the front side at the center of the right clamping plate 5 of the unit. A U-shaped refrigerant pipe 9 is arranged on the rear side at the center of the right clamping plate 5 of the unit. The U-shaped openings of the U-shaped heat medium pipe 6 and the U-shaped refrigerant pipe 9 are both located on the right side of the outer wall of the right end of the right clamping plate 5 of the unit. The left ends of the U-shaped heat medium pipe 6 and the U-shaped refrigerant pipe 9 are both close to the left clamping plate 2 of the unit. The plurality of heat conduction plates 4 are all sleeved outside the U-shaped heat medium pipe 6 and the U-shaped refrigerant pipe 9. Pipe orifice external flanges A 7 are arranged outside the two openings at the right end of the U-shaped heat medium pipe 6. Pipe orifice external flanges B 10 are arranged outside the two openings at the right end of the U-shaped refrigerant pipe 9. When using this heat exchange unit, it is necessary to directly place the heat exchange unit on a special placement rack or the ground, and then firmly install the installation fixing plates 11 on the special placement rack or the ground through the screws on the two installation fixing plates 11, so that the heat exchange unit can be firmly installed and fixed. Then, it is necessary to fixedly connect the heat medium inlet pipe and the heat medium outlet pipe to the two pipe orifice external flanges A 7 at the right end of the U-shaped heat medium pipe 6 respectively, and fixedly connect the refrigerant inlet pipe and the refrigerant outlet pipe to the two pipe orifice external flanges B 10 at the right end of the U-shaped refrigerant pipe 9 respectively. Then, the heat medium can be conveyed into the U-shaped heat medium pipe 6 through the heat medium inlet pipe, and the refrigerant can be conveyed into the U-shaped refrigerant pipe 9 through the refrigerant inlet pipe. During this process, the refrigerant and the heat medium will be mutually transferred between the heat conduction plates 4, so as to achieve the purpose of heat exchange.

[0021] As Figure 1 , Figure 2 and Figure 3As shown in the figure, a cleaning-type protection device 1 is provided at the left end of the left clamping plate 2 of the unit. The cleaning-type protection device 1 includes a U-shaped protective cover 14, a heat insulation pad 16, a push-pull anti-disengagement track 17, and high-temperature resistant cleaning bristles 18. Two push-pull anti-disengagement tracks 17 are symmetrically arranged at the left end of the top of the left clamping plate 2 of the unit. The two push-pull anti-disengagement tracks 17 are respectively welded at the corners of the front and rear ends of the top of the left clamping plate 2 of the unit. A U-shaped protective cover 14 is sleeved outside the two push-pull anti-disengagement tracks 17. The U-shaped protective cover 14 is arranged in a U-shaped opening facing downwards. A heat insulation pad 16 is fixed on the inner wall of the U-shaped part of the U-shaped protective cover 14. The heat insulation pad 16 is integrally in a U-shaped structure. Multiple groups of high-temperature resistant cleaning bristles 18 are arranged at equal intervals on the inner wall of the U-shaped part of the heat insulation pad 16. The U-shaped protective cover 14 can slide left and right outside the two push-pull anti-disengagement tracks 17. The U-shaped protective cover 14 can be completely sleeved outside the left clamping plate 2 of the unit, the front, rear and top ends of multiple heat conduction plates 4 and the right clamping plate 5 of the unit through the heat insulation pad 16.

Push-pull blocks 13 are arranged at the front, rear and top ends of the left side of the center of the U-shaped protective cover 14. When the cleaning-type protection device 1 is not in use, the U-shaped protective cover 14 is completely sleeved outside the two push-pull anti-disengagement tracks 17 at this time, so that the heat exchange unit will be completely exposed. When the heat exchange unit is put into use and the U-shaped protective cover 14 needs to be installed for protection and heat preservation, at this time, the U-shaped protective cover 14 needs to be pushed to the right through the push-pull block 13. The U-shaped protective cover 14 will slide to the outside of the heat exchange unit under the guidance of the push-pull anti-disengagement track 17 until the U-shaped protective cover 14 completely protects the outside of the heat exchange unit. In this way, it can not only protect the heat exchange unit through the U-shaped protective cover 14, but also block the influence of the external temperature on the heat exchange unit through the heat insulation pad 16. During the process of sliding the U-shaped protective cover 14 to the outside of the heat exchange unit, multiple groups of U-shaped high-temperature resistant cleaning bristles 18 on the inner wall of the heat insulation pad 16 will clean the dust and dirt attached to the outer wall of the heat exchange unit, so as to achieve the purpose of timely cleaning of the heat exchange unit.
