Description

Technical Field

[0001] The utility model belongs to the technical field of plate heat exchangers, and particularly relates to a plate heat exchanger equipped with a multi-functional housing. Background Art

[0002] A plate heat exchanger is an efficient heat exchanger formed by stacking a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is carried out through the plates. The plate heat exchanger is an ideal device for liquid-liquid and liquid-gas heat exchange. It has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small floor area, wide application, long service life, etc. Currently, the plate heat exchangers are directly exposed in the pump room without a device to protect the plate heat exchanger. In this way, the plate heat exchanger will be corroded by the surrounding environment, resulting in a decrease in service life; when the plate heat exchanger is directly exposed in the pump room, heat loss will occur in the plate heat exchanger, and the heat exchange efficiency cannot be effectively improved.

[0003] The existing publicly disclosed patent number is CN209013800U, and the public name is a plate heat exchanger equipped with a multi-functional housing, which includes a fixed plate, a rear bracket and a movable plate. An upper guide rod is installed between the upper part of the fixed plate and the upper part of the rear bracket, and a lower guide rod is installed between the lower part of the fixed plate and the lower part of the rear bracket. The upper and lower ends of the movable plate are respectively sleeved on the upper guide rod and the lower guide rod, and the movable plate slides back and forth along the upper guide rod and the lower guide rod. A plate is installed between the fixed plate and the movable plate, and multi-functional housings are sleeved on both sides of the plate. The fixed plate and the movable plate are fixed by screws and nuts.

[0004] Although the above-mentioned plate heat exchanger can improve the service life of the plate heat exchanger and can also improve the heat exchange efficiency, during the use of the above-mentioned plate heat exchanger, due to the different internal and external temperatures, water droplets are likely to be generated on the surface of the heat exchanger, resulting in rust on the surface of the heat exchange plate, thereby reducing the service life of the plate heat exchanger body.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment

[0026] Please refer to Figures 1-5 , the technical solution provided in this embodiment is as follows:

[0027] A plate heat exchanger equipped with a multi-functional housing includes: two fixed pressing plates 1. A plurality of heat exchange fins 2 are installed inside the two fixed pressing plates 1. A first air change valve 3 and a second air change valve 4 are installed on the surface of one fixed pressing plate 1, and the second air change valve 4 is located above the first air change valve 3. A plurality of guide rods 5 are arranged on both sides of the two fixed pressing plates 1. A water scraping mechanism 6 for cleaning the heat exchange fins 2 is installed on the surface of the guide rods 5 on both sides. An outer bracket 7 is installed on the surface of the fixed pressing plate 1. Two support and shock absorption mechanisms 8 for supporting the heat exchange fins 2 are installed on the surface of the outer bracket 7. The distance between the two fixed pressing plates 1 can be adjusted through the guide rods 5, and the plurality of heat exchange fins 2 are limited and fixed. Subsequently, the interior of the heat exchange fins 2 is ventilated through the first air change valve 3 and the second air change valve 4. The water scraping mechanism 6 can scrape off the water droplets on the surface of the plurality of heat exchange fins 2, thereby reducing the probability of corrosion of the surface of the heat exchange fins 2 by water droplets. At the same time, the support and shock absorption mechanism 8 can support the plurality of heat exchange fins 2, thereby reducing the probability of damage to the heat exchange fins 2 due to shaking.

[0028] Specifically, the water scraping mechanism 6 includes two protection frames 601 slidably connected to the surface of the guide rod 5. A threaded rod 602 is rotatably connected to the opposite inner surfaces of the protection frames 601. An internally threaded block 603 is threadedly connected to the surface of the threaded rod 602. A water scraping plate 605 adapted to the plurality of heat exchange fins 2 is arranged inside the internally threaded block 603. A servo motor 604 is installed on the top of the protection frame 601, and the output shaft of the servo motor 604 is fixedly connected to one end of the threaded rod 602. Two fixing bolts 608 are arranged on the surface of the internally threaded block 603, and the internally threaded block 603 is fixedly connected to the water scraping plate 605 through the two fixing bolts 608.

[0029] In a specific embodiment of the present utility model, when the servo motor 604 is started, its output shaft drives the threaded rod 602 to rotate. The rotation of the threaded rod 602 drives the internally threaded block 603 to move. The movement of the internally threaded block 603 drives the water scraping plate 605 to scrape off the water droplets on the surface of the heat exchange fins 2. The water scraping plate 605 can be conveniently disassembled from the surface of the internally threaded block 603 through the fixing bolts 608.

[0030] Specifically, reinforcing rods 606 are fixedly connected to both sides of the surface of the protection frame 601 and located on both sides of the threaded rod 602. Two sliding blocks 607 are fixedly connected to the surface of the wiper blade 605, and the two sliding blocks 607 are respectively slidably connected to the surfaces of the two reinforcing rods 606.

[0031] In a specific embodiment of the present utility model, when the wiper blade 605 moves, it drives the sliding block 607 to move on the surface of the reinforcing rod 606, thereby increasing the stability of the wiper blade 605 during movement.

[0032] Specifically, the support and shock absorption mechanism 8 includes a support frame 801 installed on the surface of the outer support 7. Both sides of the inner wall of the support frame 801 are fixedly connected with spring telescopic rods 802. One end of the inner side of the spring telescopic rod 802 is fixedly connected with a connecting shaft 803. A connecting member 804 is rotatably connected to the surface of the connecting shaft 803. The upper end of the connecting member 804 is rotatably connected with a support tray 805. A convex plate 806 in contact with a plurality of heat exchange fins 2 is fixedly connected to the top of the support tray 805. First chutes adapted to the connecting shaft 803 are provided on both sides of the support frame 801, and a second chute adapted to the connecting member 804 is provided on the upper surface of the support frame 801.

[0033] In a specific embodiment of the present utility model, when a longitudinal force acts on the heat exchange fin 2, the convex plate 806 transmits the force to the support tray 805. At this time, the support tray 805 transmits the force to the spring telescopic rod 802 through the connecting member 804 and the connecting shaft 803. At the same time, the connecting member 804 moves on the surface of the second chute, and the connecting shaft 803 moves on the surface of the first chute. At this time, the spring telescopic rod 802 absorbs the force.

[0034] Specifically, two mounting seats 807 are fixedly connected to the surface of the support frame 801. A damper 808 is installed on the surface of the mounting seat 807, and the top of the damper 808 is in contact with the convex plate 806. A buffer spring 809 is sleeved outside the damper 808, and both ends of the buffer spring 809 are respectively in contact with the mounting seat 807 and the convex plate 806.

[0035] In a specific embodiment of the present utility model, at the same time, the damper 808 and the buffer spring 809 also absorb the force generated by the convex plate 806, thereby increasing the support and buffer effect of the support and shock absorption mechanism 8.

[0036] Working principle: The distance between the two fixed pressing plates 1 can be adjusted through the guide rod 5, and a plurality of heat exchange fins 2 are limited and fixed. Subsequently, the inside of the heat exchange fins 2 is ventilated through the first ventilation valve 3 and the second ventilation valve 4. When the servo motor 604 starts, its output shaft drives the threaded rod 602 to rotate. The rotation of the threaded rod 602 drives the internally threaded block 603 to move. The movement of the internally threaded block 603 drives the wiper plate 605 to scrape the water droplets on the surface of the heat exchange fins 2. When the wiper plate 605 moves, it drives the sliding block 607 to move on the surface of the reinforcing rod 606. The wiper plate 605 can be conveniently disassembled from the surface of the internally threaded block 603 through the fixing bolt 608, thereby reducing the probability of corrosion of the surface of the heat exchange fins 2 by water droplets. When the heat exchange fins 2 are subjected to a longitudinal force, the convex plate 806 will transmit the force to the support tray 805. At this time, the support tray 805 transmits the force to the spring telescopic rod 802 through the connecting piece 804 and the connecting shaft 803. At the same time, the connecting piece 804 moves on the surface of the second chute, and the connecting shaft 803 moves on the surface of the first chute. At this time, the spring telescopic rod 802 absorbs the force. At the same time, the damper 808 and the buffer spring 809 also absorb the force generated by the convex plate 806, thereby reducing the probability of damage to the heat exchange fins 2 due to shaking.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
