Description

Technical Field

[0001] This utility model belongs to the field of evaporator equipment technology, specifically relating to a finned tube evaporator. Background Technology

[0002] Evaporation is the physical process of transforming a liquid into a gaseous state. Generally speaking, an evaporator is an object that transforms a liquid substance into a gaseous state. There are a large number of evaporators in industry, among which the evaporator used in refrigeration systems is one type. The evaporator is a very important component of the four major components of refrigeration. Low-temperature condensed liquid passes through the evaporator, exchanges heat with the outside air, vaporizes and absorbs heat, thus achieving the cooling effect.

[0003] Evaporators require rapid air intake for heat exchange to achieve rapid evaporation. Generally, heat dissipation is increased by increasing the contact area with fins, but this method is not effective enough and needs further improvement. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a finned tube evaporator.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a finned tube evaporator, including two side plates, two top plates and two door frames, wherein the two side plates, two top plates and two frames form a protective frame, characterized in that: air inlets are provided on both door frames, a pipe assembly is provided inside the protective frame, multiple heat dissipation fins are arranged laterally at the middle of the pipe assembly corresponding to the front and rear air inlets, an air inlet channel is provided on the left side of the pipe assembly, air outlet channels are provided at both ends of the air inlet channel, the two air outlet channels extend to the top and bottom of the pipe assembly respectively, multiple through holes are opened on the surface of the two air outlet channels facing the pipe assembly, and the other end of the air outlet channel extends to the right side of the pipe assembly.

[0006] Preferably, both top plates have multiple ventilation openings.

[0007] Preferably, the pipeline as a whole includes multiple front pipes, multiple rear pipes, and bends. The multiple front pipes are arranged vertically on the front side, and the multiple rear pipes are arranged vertically and vertically on the rear side of the front pipes, with intervals between them. The right sides of adjacent front pipes are connected by bends that extend backward. The left side of each front pipe is connected to one end of the corresponding rear pipe. The right sides of the multiple rear pipes are connected vertically. The front pipe at the top has an inlet, and the front pipe at the bottom has an outlet. The inlet and outlet are respectively connected through two side plates.

[0008] Preferably, the air intake channel is inserted into multiple bends from top to bottom, and a material clamping cavity is formed at each bend. The air intake channel is connected to multiple air intake pipes corresponding to each material clamping cavity, and a rotatably connected flap is provided at the opening of each air intake pipe.

[0009] Preferably, multiple annular hoops are provided on the right side of the entire pipe, and multiple auxiliary fins are provided on the inner side of each annular hoop.

[0010] The beneficial effects of this utility model are as follows: By setting up an integral pipe inside, and combining multiple front pipes, rear pipes and bends, the feed length of the liquid is greatly increased, and the overall contact area is increased, thereby achieving a better evaporation effect. Then, by setting a protective frame around the outer ring of the integral pipe, and opening multiple air inlets at the air inlet channel in the protective frame, gas can be quickly introduced. Combined with the two air outlet channels at both ends and multiple air outlets on the surface of the air outlet channels, the incoming gas can be well diverted, thereby forming a faster flow rate inside the entire protective frame, thus accelerating the evaporation effect of the entire pipe. At the same time, by forming multiple auxiliary fins between one end of the two air outlet channels, and installing the auxiliary fins on the integral pipe through annular clamps, the air outlet channels can be used to further accelerate the evaporation effect inside the integral pipe.

Detailed Implementation

[0016] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0017] Example: A finned tube evaporator, such as Figures 1-4 As shown, the structure includes two side panels 11, two top panels 14, and two door frames 12. These components form a protective frame. The two top panels 14 are located at the top and bottom between the two sides, and the two door frames 12 are located at the front and back, respectively. Multiple vents 15 are provided within each of the two top panels 14 to guide and discharge any trapped gas. The vents 15 on the bottom top panel 14 collect and discharge any condensed liquid from the surface of the entire pipe 2. Air inlets 13 are provided on each of the two door frames 12. The entire pipe 2 is housed within the protective frame. The main body 2 and the main pipe 2 have multiple heat dissipation fins 27 horizontally arranged at the air inlets 13 opened at the front and rear. The main pipe 2 has an air inlet channel 31 on the left side. The two ends of the air inlet channel 31 have air outlet channels 32. The two air outlet channels 32 extend to the top and bottom of the main pipe 2 respectively. The surfaces of the two air outlet channels 32 have multiple through holes facing the main pipe 2. The multiple through holes are opened towards the side of the heat dissipation fins 27, so that the flowing gas can be sprayed towards the side of the heat dissipation fins 27, thereby greatly accelerating the evaporation effect. The other end of the air outlet channel 32 extends to the right side of the main pipe 2.

[0018] The pipeline assembly 2 includes multiple front pipes 22, multiple rear pipes 23, and bends 24. The multiple front pipes 22 are arranged vertically on the front side, and the multiple rear pipes 23 are arranged vertically and vertically on the rear side of the front pipes 22. The right sides of adjacent front pipes 22 are connected to the bends 24 that are set to the rear. The left side of the front pipes 22 is connected to one end of the corresponding rear pipe 23. The right sides of the multiple rear pipes 23 are connected vertically. One end of the front pipe 22 at the top is provided with a feed inlet 21, and one end of the front pipe 22 at the bottom is provided with a discharge outlet 26. The feed inlet 21 and the discharge outlet 26 are respectively set through two side plates 11. The air intake channel 31 is inserted into the multiple bends 24 from top to bottom. A material clamping cavity 25 is formed at the bend 24. The air intake channel 31 is connected to multiple air intake pipes 33 corresponding to each material clamping cavity 25. Each air intake pipe 33 has a rotating flap 34 at its opening.

[0019] By setting up an internal pipe assembly 2, which is combined with multiple front pipes 22, rear pipes 23 and bends 24, the feed length of the liquid is greatly increased, and the overall contact area is increased, resulting in a better evaporation effect. Then, by setting a protective frame around the outer ring of the pipe assembly 2, multiple air inlet pipes 33 are opened at the air inlet channel 31 in the protective frame, which can quickly allow gas to enter. Together with the two air outlet channels 32 at both ends and the multiple air outlets on the surface of the air outlet channels 32, the incoming air can be well diverted, thereby forming a faster flow rate inside the entire protective frame, thus accelerating the evaporation effect of the entire pipe.

[0020] Multiple annular hoops 28 are respectively installed on the right side of the pipe assembly 2. Multiple auxiliary fins 281 are installed inside each annular hoop 28. The multiple fins are located between the other ends of the two air outlet channels 32, so that heat can be dissipated through the rapidly flowing gas. At the same time, by forming multiple auxiliary fins 281 between one end of the two air outlet channels 32, the auxiliary fins 281 are installed on the pipe assembly 2 through the annular hoop 28, so as to further accelerate the evaporation effect inside the pipe assembly 2 in conjunction with the air outlet channel 32.

[0021] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and many variations are possible. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
