[0004] However, the heat dissipation effect of the above patent is not good. The water and wind entering cannot fully contact the MVR evaporator.

[0008] As a preferred technical solution, a plurality of exhaust pipes connected to the heat dissipation channel are installed in an annular structure on the outer wall surface of the tube body, and the exhaust pipes are all arranged in an "L"-shaped structure.

[0009] As a preferred technical solution, a fixing bracket is installed on the top of each cooling fan, and the other end of each fixing bracket is installed on the inner side surface of the annular air guide portion.

[0011] As a preferred technical solution, the tube body and the ring body are both made of stainless steel.

[0012] As a preferred technical solution, a plurality of heat dissipation fins are installed on the outer wall surface of the tube body.

[0013] The beneficial effects of the utility model are as follows: the utility model has a simple structure, and the water discharged from the water inlet pipe is directly sprayed on the outer wall surface of the MVR evaporator body and flows downward along the outer wall surface, thereby increasing the contact area with the MVR evaporator body, and because only a thin layer of water is covered on one side of the outer wall surface of the MVR evaporator body, it can evaporate quickly, and the heat on the MVR evaporator body can be quickly absorbed through evaporation, and the wind energy generated by the heat dissipation fan is directly blown into the annular heat dissipation channel, thereby concentrating the wind and flowing downward along the outer wall of the MVR evaporator body until it is discharged along the exhaust pipe, and the heat in the steam and the annular heat dissipation channel is taken away by the wind energy, thereby further providing a heat dissipation effect.

[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0021] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, an MVR multi-effect evaporator of the utility model comprises an MVR evaporator body 1, the outer part of the MVR evaporator body 1 is sleeved with a tube body 2, a ring body is installed between the lower end of the tube body 2 and the MVR evaporator body 1, an annular heat dissipation channel is formed between the tube body 2, the ring body and the MVR evaporator body 1, the upper end of the tube body 2 is bent outward to form an annular guide portion 3, the interior of the annular guide portion 3 is annularly structured and a plurality of heat dissipation fans 6 are arranged, the upper end of the MVR evaporator body 1 is sleeved with an upper annular tube 4, the lower end of the MVR evaporator body 1 is sleeved with a lower annular tube 7, a plurality of water inlet pipes 11 are installed on the bottom surface of the upper annular tube 4, and a plurality of water outlet pipes 10 connected with the annular heat dissipation channel are installed between the lower annular tube 7 and the ring body.

[0023] In this embodiment, the lower end of the water inlet pipe 11 is bent toward the MVR evaporator body 1, and the water outlet end of the water inlet pipe 11 is arranged close to the outer wall of the MVR evaporator body 1. A water delivery pipe is installed on one side of the upper annular tube 4, and the other end of the water delivery pipe is bent upward and passed through the annular guide part 3. A drain pipe 8 is installed on one side of the lower annular tube 7.

[0024] In this embodiment, a plurality of exhaust pipes 9 connected to the heat dissipation channel are installed in an annular structure on the outer wall surface of the tube body 2. The exhaust pipes 9 are all arranged in an "L"-shaped structure, so that water entering the annular heat dissipation channel cannot be discharged from the exhaust pipe, while the entered gas can be discharged along the exhaust pipe.

[0025] In this embodiment, a fixing frame is installed on the top of each of the heat dissipation fans 6 , and the other end of each of the fixing frames is installed on the inner side surface of each of the annular air guide portions 3 .

[0026] In this embodiment, a plurality of connecting rods are installed between the upper annular tube 4 and the MVR evaporator body 1, so that the upper annular tube can be fixed on the MVR evaporator body, avoiding movement of the upper annular tube to ensure the stability of drainage.

[0027] In this embodiment, the tube body 2 and the ring body are both made of stainless steel, which prevents rust and increases the service life.

[0028] In this embodiment, a plurality of heat dissipation fins are installed on the outer wall surface of the tube body 2, and the heat dissipation fins increase the natural heat dissipation effect outside the tube body.

[0029] When in use, the water injection pipe is connected to an external water source, so that external water can be injected into the upper annular pipe along the water injection pipe until it is discharged along the water inlet pipe. Since the lower end of the water inlet pipe is bent toward the MVR evaporator body, the discharged water can be directly sprayed on the outer wall surface of the MVR evaporator body and flow downward along the outer wall surface, increasing the contact area with the MVR evaporator body. Since only a thin layer of water is covered on one side of the outer wall surface of the MVR evaporator body, it can evaporate quickly, and the heat on the MVR evaporator body can be quickly absorbed through evaporation. The water can eventually be discharged into the lower annular pipe along the water outlet pipe until it is discharged along the drain pipe. The discharged water can be collected to avoid waste.

[0030] During the water cooling process, the cooling fan can be started. The wind generated by the cooling fan can be blown directly into the annular heat dissipation channel along the annular guide part, thereby concentrating the wind and flowing downward along the outer wall of the MVR evaporator body until it is discharged along the exhaust pipe. The wind can take away the heat in the steam and the annular heat dissipation channel, further providing a heat dissipation effect.

[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
