It is usually composed of evaporator, absorber, generator and condenser, etc., and realizes heat transfer and heat exchange through the reciprocating absorption and desorption process.

[0003] The absorption chamber heat pump type heat exchanger unit currently used in the prior art installs many devices in one frame. The prior art has a movable design for the frame to facilitate the use of the unit. However, since the heat exchange efficiency of the plate heat exchanger in the unit depends on the number of plates and the interval spacing, and its frame part is a welded steel frame, the plate heat exchanger cannot be adjusted specifically, which reduces its applicability. In this regard, an absorption heat pump type heat exchanger unit is proposed to solve the above-mentioned problems. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] See also Figure 1-3 In this embodiment, an absorption heat pump type heat exchange unit includes a frame 1 and a unit device installed on the frame 1. The unit equipment specifically includes an evaporator, an absorber, a generator and a condenser for completing a cycle. A plate heat exchanger 3 for heat exchange is also installed on the frame 1. The plate heat exchanger 3, as a component of the evaporator, plays a role in rapid heat exchange.

[0021] In this embodiment, a bracket 2 for fixing the plate heat exchanger 3 is fixedly installed outside the plate heat exchanger 3, a reinforcing rod 4 is fixedly installed inside the frame 1, and a connecting member for connecting the plate heat exchanger 3 is provided between the reinforcing rod 4 and the frame 1.

[0022] It should be noted that the connecting member includes a threaded rod 6 fixedly installed between the inner walls of the frame 1 and a movable plate 5 located outside the threaded rod 6, wherein the movable plates 5 include two, and both movable plates 5 are penetrated with preset holes to facilitate threaded connection at both ends of the corresponding bracket 2.

[0023] In this embodiment, both sides of the movable plate 5 are recessed inwards, and one end of the movable plate 5 is slidably connected to the reinforcing rod 4 .

[0024] Such a design improves the sliding stability of the movable panel 5 relative to the reinforcing rod 4 .

[0025] In this embodiment, a movable tube 7 is fixedly installed on the movable plate 5, and the movable tube 7 is slidably connected to the threaded rod 6. The movable tube 7 is movable relative to the threaded rod 6, so that the movable plate 5 can be moved and adjusted relative to the threaded rod 6, so that the plates of the plate heat exchanger 3 can be disassembled or adjusted.

[0026] It should be noted that nuts 8 are rotatably installed at both ends of the movable tube 7 , and the nuts 8 are threadedly fitted to the threaded rod 6 . The rotation locking of the nuts 8 can limit the sliding of the movable tube 7 relative to the threaded rod 6 .

[0027] In this embodiment, a locking member for locking the nut 8 is further provided on the outside of the threaded rod 6 , so as to improve the stability of the movable plate 5 after adjustment.

[0028] In this embodiment, the locking member includes a first toothed ring 9 fixedly mounted on one end of the nut 8 and a second toothed ring 11 movably connected to the outside of the threaded rod 6. The toothed surfaces of the first toothed ring 9 and the second toothed ring 11 are relatively oriented, and the first toothed ring 9 and the second toothed ring 11 can be meshed with each other by bringing them relatively close.

[0029] It should be noted that a mounting ring 10 is slidably mounted on the outside of the threaded rod 6 , and the second gear ring 11 is fixedly connected to the mounting ring 10 , and the second gear ring 11 can be pulled to move by the movement of the mounting ring 10 .

[0030] It is worth noting that a limiting rod 12 is fixedly installed in the middle of the mounting ring 10 , a groove 13 is penetrated through the middle of the threaded rod 6 , and the limiting rod 12 is slidably connected to the groove 13 .

[0031] In a specific implementation, by limiting the relative sliding of the rod 12 and the groove 13, the rotation of the mounting ring 10 relative to the threaded rod 6 is restricted, and the rotation of the first gear ring 9 can be restricted by meshing the second gear ring 11 fixedly connected to the mounting ring 10 with the first gear ring 9.

[0032] In order to limit the position of the mounting ring 10 , a clamping rod 14 is fixedly installed on the outside of the mounting ring 10 in this embodiment, and a clamping plate 15 is fixedly installed on the outside of the movable tube 7 , and the clamping rod 14 is clamped to the clamping plate 15 .

[0033] Specifically, the top of the card rod 14 is equally divided into three sections, and the three sections all adopt elastic rods. The card plate 15 is preset with holes for the three sections of elastic rods at the top of the card rod 14 to pass through, so that the card rod 14 can be extended to one side of the card plate 15. At the same time, the end of the card rod 14 has an arc-shaped card block, which passes through the card plate 15 and then hooks on the outer surface of the card plate 15, so that the card rod 14 and the card plate 15 are engaged with each other.

[0034] The working principle of the above embodiment is:

[0035] By manually rotating the nuts 8 at both ends of the movable tube 7 on a movable plate 5, the movable tube 7 can be adjusted relative to the threaded rod 6. After the positions of the two movable plates 5 are adjusted, the mounting ring 10 located outside the threaded rod 6 is slid so that the mounting ring 10 and the second toothed ring 11 fixedly connected thereto and the first toothed ring 9 located outside the nut 8 are brought close to and meshed with each other. At this time, when the clamping rod 14 located on the mounting ring 10 approaches the movable tube 7, the clamping rod 14 penetrates and is clamped on the clamping plate 15 to limit the relative positions of the first toothed ring 9 and the second toothed ring 11, so that the nut 8 fixedly connected to the first toothed ring 9 is restricted in rotation and the position of the movable plate 5 is stabilized. At this time, according to the positions of the two movable plates 5 after adjustment, the plate heat exchanger 3 can be flexibly adapted and adjusted.
