Description

Technical Field

[0001] The utility model relates to the technical field of surface coolers, in particular to an antifreeze type surface cooler. Background Art

[0002] Surface cooler, full name surface cooler, its principle is to let the heat medium or cool medium or refrigerant flow through the inner cavity of the metal pipe, and the air to be treated flows through the outer wall of the metal pipe for heat exchange to achieve the purpose of heating or cooling the air. According to the literal meaning, it can be understood as a finned heat exchanger. In actual engineering, the fluid medium in the surface cooler tube is usually water, ethylene glycol solution, antifreeze, etc.

[0003] According to the authorization announcement number: CN220489455U, a surface cooler antifreeze device relates to the field of surface cooler antifreeze technology, including a surface cooler main frame with a water pipe inside, a cavity for placing the water pipe is opened inside the surface cooler main frame, and insulation components are provided on the front and back sides of the cavity to achieve insulation of the water pipe and facilitate replacement or maintenance. The top of the surface cooler main frame is provided with an antifreeze component to achieve antifreeze of the water pipe and prevent the water pipe from freezing in winter, which affects user use. The insulation component includes an insulation board wrapped around the outer periphery of the water pipe. The utility model can replace the insulation board by sliding the handles on both sides of the insulation board up and down on the L-shaped slide groove. At the same time, the air pump works to circulate the gas inside the surface cooler main frame, extract it, heat it, and then send it into the surface cooler main frame through a number of suction pipes.

[0004] Based on the above-mentioned antifreeze device for the surface cooler, the antifreeze component and the insulation component are cooperated to make the built-in heat exchange tubes of the surface cooler obtain the effects of insulation and antifreeze, thereby avoiding freezing during use and further avoiding the internal liquid from being unable to be discharged due to freezing when it needs to be emptied. However, since the heat exchange tubes inside the device are arranged in a forward horizontal sequence as a whole, when emptying, due to the height difference and the small diameter of the heat exchange tubes, the liquid will still generate viscosity when flowing through, thereby increasing the flow resistance, making it difficult to empty the liquid in the surface cooler, thereby affecting subsequent work.

[0005] Therefore, in summary, there is an urgent need for an antifreeze type surface cooler that is easy to empty. Utility Model Content

The drain pipe 6 is arranged longitudinally, and its top end is in a closed state, and its bottom end passes through the right part of the shell 2. The drain pipe 6 is communicated with all the first connecting tubes 5 and can be used for liquid discharge. The middle part of the seven first connecting tubes 5 is penetrated by a rotatable connecting shaft 7. The connecting shaft 7 is provided with seven stop valves 71 at intervals from top to bottom. The stop valve 71 is placed inside the first connecting tube 5, and its shape is a sphere, which can be used to limit the circulation of water flow. The stop valve 71 is rotatably contacted and matched with the first connecting tube 5 of the same height. A water valve 72 is arranged on the top of the connecting shaft 7. The rotation of the water valve 72 drives the connecting shaft 7 to rotate, and then the stop valve 71 rotates. After the stop valve 71 rotates, there is no obstruction inside the first connecting tube 5, so that the liquid can circulate.

[0027] like Figure 5 As shown, a heater 8 and a first fan 9 are also included. The interior of the base 1 is hollow, and the heater 8 is fixedly installed inside the base 1. The first fans 9 are symmetrically arranged on both sides of the top of the heater 8. The first fan 9 can convert the heat generated by the heater 8 into wind power, and the top of the first fan 9 is embedded in the bottom of the outer shell 2. The two are connected to allow hot air to enter the interior of the outer shell 2.

[0028] like Figure 2 , Figure 5 and Figure 6 As shown, it also includes a second connecting pipe 10, a guide plate 101 and a second fan 11. The second connecting pipe 10 is arranged at the rear of the outer shell 2. The bottom end of the second connecting pipe 10 is communicated with the base 1, and the top end thereof is communicated with the outer shell 2, forming a state in which the upper and lower layers are interconnected. The guide plates 101 are arranged on both the upper and lower sides of the second connecting pipe 10. The guide plates 101 are streamlined and suitable for the circulation of gas. The second fan 11 is arranged inside the top end of the second connecting pipe 10. The second fan 11 is used for wind conversion of heat in the second connecting pipe 10, thereby forming a state in which upper and lower hot air converge.

[0029] like Figure 7 As shown, it also includes a sliding plate 12 and a fixed block 13. An empty slot is opened on the left side of the shell 2. The empty slot is located at the upper side of the shell 2 and is suitable for the height of the water valve 72, which can assist in its opening operation. The sliding plate 12 is slidably arranged in the empty slot of the shell 2. The sliding plate 12 slides up and down, and a fixed block 13 is arranged on the upper side of the left part of the sliding plate 12.

[0030] like Figure 7 As shown, a fixing plate 14 and a hook 15 are also included. The fixing plate 14 is arranged on the left part of the housing 2. The fixing plate 14 is located above the empty slot of the housing 2. A hook 15 is rotatably arranged on the fixing plate 14. The hook 15 is snap-fitted with the fixing block 13. The fixing block 13 is clamped by the hook 15 to fix the sliding plate 12, thereby realizing the limiting of the sliding plate 12.

[0031] When it is necessary to drain the cooler 4, the staff first places the device on a horizontal surface so that the base 1 is in a stable state, and then rotates the hook 15 so that the hook 15 rotates counterclockwise on the fixed plate 14, thereby disengaging the fixed block 13 on the sliding plate 12, and then moves the sliding plate 12 downward to slide downward, opening the empty slot on the shell 2, and then the internal water valve 72 can be seen. The staff twists the water valve 72, and the water valve 72 drives the connecting shaft 7 connected thereto to rotate during the rotation process, and then drives the stop valve 71 connected to the connecting shaft 7 to rotate, so that a gap for liquid circulation is formed between the first connecting pipe 5 and the inside through the twisting, and the liquid flows toward the heat exchange pipe of the cooler 4 without the obstruction of the stop valve 71. The liquid flows in the direction of inclination toward the first connecting pipe 5 and then gathers into the drain pipe 6. Then, the valve on the drain pipe 6 can be opened to discharge the liquid. If the temperature is cold, the staff can start the heater 8 and then start the first fan 9, so that the first fan 9 fills the shell 2 with hot air to defrost the internal cooler 4. At the same time, the second connecting pipe 10 will also guide the heat generated by the heater 8, so that it passes through the second connecting pipe 10 and enters the upper layer of the shell 2 under the guidance of the guide plate 101. Then, the hot air is poured into the interior through the second fan 11 to form a hot air circulation, so that the hot air is evenly distributed in the upper and lower layers of the shell 2, and the cooler 4 can obtain a more uniform heating effect, thereby achieving a better antifreeze effect.
