Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of high-temperature fans, in particular to a heat insulation device for high-temperature fans. Background Art
[0002] High temperature fans are special fans, mainly used for high temperature operations, and are specially used in high temperature workplaces. The operating temperature is generally between 100-180°C. The material has strong resistance to high temperature and high pressure. High temperature fans mainly include stainless steel high temperature fans, transmission high temperature fans, centrifugal high temperature fans, etc. High temperature fans are widely used in chemical industry, petroleum, metallurgy, forging, electric power, nuclear power plants, environmental protection and other fields.
[0003] At present, high-temperature fans are in use. Since high-temperature fans work in a high-temperature environment for a long time, they are very easy to age due to the high-temperature environment, which greatly reduces the service life of the high-temperature fans. Therefore, high-temperature fans are usually equipped with heat dissipation devices to dissipate heat and cool the high-temperature fans. However, traditional heat dissipation devices are usually arranged inside the high-temperature fans. When heat dissipation is performed, the high-temperature airflow has already contacted the components inside the high-temperature fan. It is impossible to effectively insulate before the high-temperature airflow enters the heat dissipation fan and contacts the components, resulting in poor heat dissipation effect.

[0004] The purpose of the utility model is to provide a high-temperature fan heat insulation device with good heat dissipation effect, which effectively solves the problems raised in the above-mentioned background technology.
[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.
[0006] A high-temperature fan heat insulation device comprises a heat dissipation cylinder and a heat dissipation pipe. The heat dissipation pipe is installed on the high-temperature fan, and the heat dissipation cylinder is fixed on the end of the heat dissipation pipe. One end of the heat dissipation cylinder has an air inlet, and the other end has an air outlet. One end of the heat dissipation pipe is communicated with the air outlet, and the other end is communicated with the inlet of the high-temperature fan. A heat exchange type heat dissipation mechanism is provided on the heat dissipation cylinder, and a liquid cooling type heat dissipation mechanism is provided on the heat dissipation pipe.
[0007] It can be seen that the utility model can transfer the temperature of the incoming airflow to the outside of the heat sink through the heat exchange heat dissipation mechanism on the heat sink, thereby realizing heat exchange cooling; the airflow passing through the heat sink can be water-cooled and dissipated through the liquid-cooled heat dissipation mechanism on the heat sink, and then before the high-temperature airflow enters the high-temperature fan, the heat insulation device can cool the airflow, thereby playing a good heat insulation role, preventing the high-temperature airflow from directly contacting the internal parts of the fan and aggravating damage, thereby increasing the service life of the high-temperature fan, and combining the heat exchange cooling effect and the water-cooled heat dissipation effect to realize two-stage cooling and cooling, with better cooling and heat insulation effects, thereby providing better protection for the high-temperature fan.
[0008] Furthermore, the heat exchange type heat dissipation mechanism includes a round rod, a plurality of heat dissipation fins and a plurality of diverter plates. The round rod is arranged in the heat dissipation tube and remains coaxial with the heat dissipation tube. The heat dissipation fins are arranged in an annular array on the outer wall of the round rod and extend through and to the outside of the heat dissipation tube. A heat exchange cavity is formed between two adjacent heat dissipation fins. The diverter plate annular array is arranged on the end face of the round rod away from the air outlet, and a diverter cavity is formed between two adjacent diverter plates.
[0009] Furthermore, the liquid-cooled heat dissipation mechanism includes a first annular cavity, a second annular cavity, a plurality of cooling cavities, a water inlet and a water outlet, the first annular cavity is arranged in the heat dissipation pipe and on a side close to the heat dissipation tube, the second annular cavity is arranged in the heat dissipation pipe and on a side away from the heat dissipation tube, and the plurality of cooling cavities are arranged in the heat dissipation pipe in an annular array around the axis of the heat dissipation tube, one end of each heat dissipation tube is communicated with the first annular cavity, and the other end is communicated with the second annular cavity, the water inlet is fixed on the heat dissipation tube and is communicated with the first annular cavity, and the water outlet is fixed on the heat dissipation tube and is communicated with the second annular cavity.
[0010] Furthermore, a spiral body is fixed inside the heat dissipation pipe, and a spiral channel is formed between the outer surface of the spiral body and the inner wall of the heat dissipation pipe.
[0011] Furthermore, a filter is installed in the air inlet.
[0012] Furthermore, the filter is fixed inside the externally threaded cylinder, and the inner wall of the air inlet is provided with an internal thread for matching and installing with the threads of the externally threaded cylinder.
[0013] Compared with the prior art, the beneficial effects of the present invention are as follows.
[0014] 1. The utility model can transfer the temperature of the incoming airflow to the outside of the heat dissipation tube through the heat exchange type heat dissipation mechanism on the heat dissipation tube, thereby realizing heat exchange cooling. The airflow passing through the heat dissipation tube can be water-cooled by the liquid cooling type heat dissipation mechanism on the heat dissipation tube. Then, before the high-temperature airflow enters the high-temperature fan, the heat insulation device can cool the airflow, thereby playing a good heat insulation role, avoiding direct contact between the high-temperature airflow and the internal parts of the fan to aggravate damage, and prolonging the service life of the high-temperature fan.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.
[0026] See also Figure 1-Figure 5 The utility model provides a high-temperature fan insulation device, including a heat dissipation tube 1 and a heat dissipation pipe 2. The heat dissipation pipe 2 is installed on the high-temperature fan, and the heat dissipation tube 1 is fixed on the end of the heat dissipation pipe 2. One end of the heat dissipation tube 1 has an air inlet 11, and the other end has an air outlet 12. One end of the heat dissipation pipe 2 is communicated with the air outlet 12, and the other end is communicated with the inlet of the high-temperature fan. A heat exchange type heat dissipation mechanism 3 is provided on the heat dissipation tube 1, and a liquid cooling type heat dissipation mechanism 4 is provided on the heat dissipation pipe 2.
[0027] When the high-temperature fan is working, the high-temperature air flows into the heat sink 1 through the air inlet 11, and then flows into the heat sink 2 through the air outlet 12, and then enters the high-temperature fan through the heat sink 2 and the air inlet of the high-temperature fan, and is finally discharged through the outlet. In this process, the temperature of the incoming airflow can be exchanged to the outside of the heat sink 1 through the heat exchange heat dissipation mechanism 3 on the heat sink 1 to achieve heat exchange cooling, and the airflow flowing through the heat sink 2 can be water-cooled by the liquid-cooled heat dissipation mechanism 4 on the heat sink 2. Before the high-temperature airflow enters the high-temperature fan, the heat insulation device can cool the airflow and play a good heat insulation role, thereby preventing the high-temperature airflow from directly contacting the internal parts of the fan and aggravating damage, thereby increasing the service life of the high-temperature fan. In addition, the heat exchange cooling effect achieved by the heat exchange heat dissipation mechanism 3 and the water-cooling heat dissipation effect achieved by the liquid-cooled heat dissipation mechanism 4 achieve two-stage cooling and cooling, and the cooling and heat insulation effect is better, thereby providing better protection for the high-temperature fan.
[0028] Specifically, the heat exchange type heat dissipation mechanism 3 includes a round rod 31, a plurality of heat dissipation fins 32 and a plurality of diverter plates 33. The round rod 31 is arranged in the heat dissipation tube 1 and is coaxial with the heat dissipation tube 1. The heat dissipation fins 32 are arranged in an annular array on the outer wall of the round rod 31 and extend through the outside of the heat dissipation tube 1. A heat exchange cavity 321 is formed between two adjacent heat dissipation fins 32. The diverter plates 33 are arranged in an annular array on the end surface of the round rod 31 away from the air outlet 12. A diverter plate 33 is formed between two adjacent diverter plates 33. When the airflow enters the heat dissipation tube 1 through the air inlet 11, the airflow is first diverted to each diversion cavity 331 through the diverter plate 33, and then flows into each heat exchange cavity 321 through the diverter cavity 331, so that the high-temperature airflow is diverted in advance to avoid excessive heat accumulation and improve the uniformity of the heat dissipation effect. The temperature of the airflow entering the heat exchange cavity 321 is absorbed by the aluminum heat dissipation fins 32 and is transmitted to the outside of the heat dissipation tube 1 through the heat dissipation fins 32, thereby realizing diversion heat exchange cooling and heat dissipation.
[0029] Specifically, the liquid-cooled heat dissipation mechanism 4 includes a first annular cavity 41, a second annular cavity 42, a plurality of cooling cavities 43, a water inlet 44 and a water outlet 45. The first annular cavity 41 is arranged in the heat dissipation pipe 2 and is close to the side of the heat dissipation tube 1. The second annular cavity 42 is arranged in the heat dissipation pipe 2 and is away from the side of the heat dissipation tube 1. The plurality of cooling cavities 43 are arranged in the heat dissipation pipe 2 in an annular array around the axis of the heat dissipation pipe 2. One end of each heat dissipation pipe 2 is connected to the first annular cavity 41, and the other end is connected to the second annular cavity 42. The water inlet 44 is fixed on the heat dissipation pipe 2 and is connected to the first annular cavity 41. The water outlet 45 is fixed on the heat dissipation pipe 2 and is connected to the The second annular cavity 42 is interconnected, and the coolant enters the first annular cavity 41 through the water inlet 44, flows into the second annular cavity 42 through the cooling cavity 43, and is finally discharged through the water outlet 45. In this process, when the airflow enters the heat dissipation pipe 2, the heat is absorbed by the inner wall of the heat dissipation pipe 2, and then the heat is transferred to the heat dissipation pipe 2, and the coolant flowing through the cooling cavity 43 can absorb the heat on the heat dissipation pipe 2 and discharge it, thereby realizing water-cooled heat dissipation. In addition, a plurality of cooling cavities 43 are distributed around the heat dissipation pipe 2 array to ensure that the water-cooled heat dissipation points are evenly distributed, sufficient to cover the heat dissipation of the entire heat dissipation pipe 2, and the heat dissipation effect of the airflow in the heat dissipation pipe 2 is uniform and thorough.
[0030] Specifically, a spiral body 21 is fixed in the heat dissipation pipe 2, and a spiral channel 22 is formed between the outer surface of the spiral body 21 and the inner wall of the heat dissipation pipe 2. By installing the spiral body 21 in the heat dissipation pipe 2, the spiral channel 22 is formed in the heat dissipation pipe 2. After the airflow enters the heat dissipation pipe 2, it flows along the spiral channel 22 in a spiral trajectory, which increases the circulation distance of the airflow in the heat dissipation pipe 2, thereby extending the time for the airflow to be cooled in the heat dissipation pipe 2, so that the airflow is cooled more fully in the heat dissipation pipe 2, and the cooling effect of the airflow is further improved.
[0031] Specifically, a filter 111 is installed in the air inlet 11, and the filter 111 can filter out particulate impurities in the airflow to prevent them from entering the heat dissipation cylinder 1 and the heat dissipation tube 2 and excessively accumulating on components to affect the normal circulation of the airflow.
[0032] Specifically, the filter 111 is fixed inside the externally threaded cylinder 112, and an internal thread is provided on the inner wall of the air inlet 11 for the externally threaded cylinder 112 to be threadedly matched and installed. The externally threaded cylinder 112 is threadedly matched and screwed into the air inlet 11 to achieve a detachable installation of the filter 111. Long-term filtration work causes a large amount of dust particles to accumulate on the filter 111. The detachable installation method can facilitate the regular removal of the filter 111 and the externally threaded cylinder 112 as a whole from the air inlet 11 for cleaning.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
