Description

Technical Field

[0001] The utility model relates to the technical field of plate heat exchangers, in particular to a plate heat exchanger which is convenient to assemble. Background Art

[0002] The plate heat exchanger is a high-efficiency heat exchanger made of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between the various plates, and heat is exchanged through the plates.

[0003] For example, a Chinese patent document with a publication number of CN218034590U discloses a plate heat exchanger pipe assembly structure, which includes a plate heat exchanger body and a heat exchange tube, wherein water exchange tubes are fixedly arranged at the water inlet and the water outlet of the plate heat exchanger body, a fixed tube is welded to the end of the heat exchange tube close to the plate heat exchanger, and the fixed tube extends into the water exchange tube, and a first connecting plate is fixedly arranged at the end of the water exchange tube away from the plate heat exchanger body, and a second connecting plate is fixedly arranged at the end of the heat exchange tube close to the plate heat exchanger body, and the first connecting plate is hingedly provided with fixing plates at the upper and lower ends of one side close to the plate heat exchanger body, respectively, and the internal thread of the fixing plate away from the end of the plate heat exchanger body is connected with a bolt, and the end of the bolt close to the first connecting plate is detachably connected to the second connecting plate.

[0004] It can be seen from the above disclosed content that in the above technical solution, through the provision of the first fixing plate and the bolts, the first connecting plate and the second connecting plate can be easily installed and fixed, making the installation and disassembly between the heat exchange tube and the plate heat exchanger more convenient.

[0005] However, during the installation of the plates, adjacent plates need to be installed in a centrally symmetrical manner to ensure that after all plates are installed, a honeycomb shape is formed on the sides of the plates. However, in the above technical solution, there is a lack of identification marks on the plates, which may lead to incorrect installation. Therefore, an inspection is required after the installation is completed, which makes the overall installation somewhat inconvenient. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a plate heat exchanger that is easy to assemble and can facilitate the correct installation of the plates to improve the convenience of the overall installation.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a plate heat exchanger that is easy to assemble, comprising a base and a pressure seat, a plate is arranged between the base and the pressure seat, a guide rod extending in a horizontal direction is fixed on the base, the plate slides toward the base through the guide rod, the pressure seat is used to press adjacent plates, an installation frame is arranged on the outer periphery of the plate, a positioning hole and a positioning protrusion extending to both sides are arranged on the installation frame, the positioning hole and the positioning protrusion are centrally symmetrical, and the positioning protrusion is adapted to the positioning hole.

[0008] The utility model is further configured as follows: an arc groove opposite to the guide rod is provided on the installation frame, an embedding groove connected to the arc groove is provided in the arc groove, a ball matched with the embedding groove is provided in the embedding groove, the ball can roll in the embedding groove and partially extend outside the embedding groove as a coupling part, the coupling part contacts the guide rod and can form a sliding fit between the two.

[0009] The utility model is further configured as follows: the base and the pressure seat side walls are respectively provided with a first card slot and a second card slot, the second card slot is opposite to the first card slot, a locking rod is provided between the first card slot and the second card slot, the locking rod can form a card-fitting fit with the first card slot and the second card slot, and threaded portions are provided at both ends of the locking rod, and the threaded portions are connected to locking nuts that can form a threaded fit with the threaded portions.

[0010] The utility model is further configured as follows: the length of the positioning protrusion is not greater than half the depth of the positioning hole.

[0011] The utility model is further configured as follows: the thickness of the installation frame is the same as the thickness of the plate.

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

[0013] By providing a mounting frame on the periphery of the plate, and providing positioning holes and positioning protrusions on the mounting frame, since the positioning holes and the positioning protrusions are centrally symmetrical with each other, when multiple plates are installed, after the subsequent plate is rotated 180 degrees, the positioning holes and positioning protrusions on the plate can respectively correspond to the positioning protrusions and positioning holes of the previous plate. Therefore, the fool-proof design can prevent adjacent plates from overlapping each other when installing multiple plates, that is, if adjacent plates are installed in the same direction, the positioning protrusions on adjacent plates will interfere with each other. Therefore, the technical problem in the prior art that there is no identification on the plate and it is easy to install the plate incorrectly is effectively solved. Furthermore, when installing each plate, it can be judged whether there is an error in the current installation direction of the plate, making it more convenient and quick to correctly install each plate.

[0018] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0020] like Figures 1 to 4 As shown, the utility model discloses a plate heat exchanger which is easy to assemble, including a base 1 and a pressure seat 2, a plate 3 is arranged between the base 1 and the pressure seat 2, a guide rod 4 extending in the horizontal direction is fixed on the base 1, the plate 3 slides toward the base 1 through the guide rod 4, the pressure seat 2 is used to press the adjacent plates 3, a mounting frame 5 is arranged on the periphery of the plate 3, a positioning hole 51 and a positioning protrusion 52 extending to both sides are arranged on the mounting frame 5, the positioning hole 51 is centrally symmetrical with the positioning protrusion 52, the positioning protrusion 52 is adapted to the positioning hole 51, and since the positioning hole 51 and the positioning protrusion 52 are centrally symmetrical with each other, Therefore, when installing multiple plates 3, after the subsequent plate 3 is rotated 180 degrees, the positioning hole 51 and the positioning protrusion 52 on the plate 3 can be respectively opposite to the positioning protrusion 52 and the positioning hole 51 of the previous plate 3. The fool-proof design can prevent adjacent plates 3 from overlapping each other when installing multiple plates 3. That is, if adjacent plates 3 are installed in the same direction, the positioning protrusions 52 on adjacent plates 3 will interfere with each other. Then, when installing each plate 3, it can be determined whether there is an error in the installation direction of the current plate 3, making it more convenient and quick to correctly install each plate 3.

[0021] In this embodiment, an arc groove 53 opposite to the guide rod 4 is further provided on the installation frame 5, and an embedding groove 54 connected to the arc groove 53 is provided in the arc groove 53, and a ball 6 matched with the embedding groove 54 is provided in the embedding groove 54. The ball 6 can roll in the embedding groove 54 and partially extend to the outside of the embedding groove 54 as a coupling portion. The coupling portion contacts the guide rod 4 and can form a sliding fit between the two. During the installation of the plate 3, the ball 6 coupled to the guide rod 4 through the coupling portion can roll with the push of the plate 3, thereby guiding the push of the plate 3, and because the ball 6 can rotate in the embedding groove 54, the friction generated when the ball 6 contacts the guide rod 4 is rolling friction, thereby reducing the friction force on the plate 3 during the pushing process, thereby facilitating the installation of the plate 3.

[0022] In this embodiment, a first card slot 201 and a second card slot 101 are respectively provided on the side walls of the base 1 and the pressure seat 2, the second card slot 101 is opposite to the first card slot 201, and a locking rod 7 is provided between the first card slot 201 and the second card slot 101, the locking rod 7 can be snap-fitted with the first card slot 201 and the second card slot 101, and threaded portions 71 are provided at both ends of the locking rod 7, and the threaded portion 71 is connected with a locking nut 8 that can be threadedly fitted with the threaded portion 71. The locking rod 7 is snap-fitted with the first card slot 201 and the second card slot 101, so that the locking rod 7 can be disassembled. After each plate 3 is installed, the pressure seat 2 is slid toward the base 1 so that the pressure seat 2 contacts the plate 3, and then the locking nut 8 is screwed into the threaded portion 71, so that each plate 3 can be tightly pressed through the pressure seat 2.

[0023] In this embodiment, the length of the positioning protrusion 52 is not greater than half the depth of the positioning hole 51, so that the positioning hole 51 on the plate 3 can simultaneously accommodate the positioning protrusion 52 on the plates 3 on both sides, thereby ensuring that adjacent plates 3 can contact each other. In addition, the thickness of the mounting frame 5 should be the same as the thickness of the plate 3, thereby preventing the setting of the mounting frame 5 from interfering when adjacent plates 3 contact, thereby ensuring that adjacent plates 3 can contact each other.

[0024] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
