Description

Blower fan unit of the environmental simulation chamber

[0001] The present invention relates to a blower fan unit of an environmental simulation chamber, and more particularly, to a blower fan unit of an environmental simulation chamber capable of quickly implementing temperature conversion conditions required for components or products that require testing in a high or low temperature environment.

[0002]

[0003] In general, an environmental simulation chamber refers to testing equipment used to test the durability, reliability, and thermal shock of parts and products under high or low temperature environments.

[0004] These environmental simulation chambers heat or cool the air inside the chamber through heaters or coolers after placing the parts or products for testing inside.

[0005] At this time, the air is regulated to a temperature that matches the set test temperature conditions, and a blower fan unit is provided to maintain the temperature inside the chamber uniformly.

[0006] The blower fan unit functions to control the temperature inside the chamber by generating air circulation inside the chamber. The temperature inside the chamber is maintained uniformly by an impeller (or various types of fans such as cross fans) that is dynamically connected to a motor and rotates inside the chamber.

[0007] Since these conventional blower fan units are installed inside a chamber, they are continuously subjected to harsh high or low temperature conditions, which can cause damage to component parts, and in particular, there is a problem of accelerating damage to the motor as unnecessary heat is transmitted to the motor.

[0008] In addition, when installing or maintaining the blower fan unit, there were inconveniences in the work of connecting or separating each component within the limited space of the chamber.

[0009]

[0010] The present invention has been devised to solve the problems of the above-mentioned prior art, and its purpose is to provide a blower fan unit of an environmental simulation chamber that can prevent damage to the motor due to heat by blocking the transmission of a heat source to the motor.

[0011] In addition, the purpose is to provide a blower fan unit of an environmental simulation chamber that can facilitate repair or replacement of damaged parts by integrating the parts that constitute the invention to facilitate installation and removal within the chamber.

[0012]

[0013] In order to solve the above-described problem, the blower fan unit of the environmental simulation chamber according to the present invention comprises: a motor; an insulation box having an outer surface on which the motor is coupled, an inner space filled with insulation, and mounted within the chamber so that the motor is positioned outside the environmental simulation chamber; a blower fan including a housing, an impeller provided within the housing, and a shaft provided at a side end of the impeller and penetrating the side surface of the housing; and a coupling connecting the shaft of the blower fan and the rotational axis of the motor penetrating the insulation box to provide rotational force of the motor to the shaft, thereby causing the impeller to rotate.

[0014] In addition, the present invention further comprises a protective cover installed on one side of the housing of the blower fan and housing the shaft of the blower fan, the rotational axis of the motor penetrating the insulation box, and the coupling therein.

[0015] Here, a bearing that rotatably supports the rotational axis of the motor is installed on the housing side of the blower fan, and the bearing is accommodated inside the protective cover.

[0016] In addition, the present invention further comprises a heat dissipation part, one side of which is in close contact with the outer surface of the protective cover and the other side of which penetrates the insulating box and then protrudes out of the chamber, thereby dissipating heat inside the protective cover out of the chamber.

[0017] Here, the heat dissipation unit is composed of a heat absorption panel that is in close contact with the outer surface of the protective cover; a plurality of heat absorption fins that are spaced apart from the heat absorption panel; a heat pipe that has one end connected to the heat absorption panel and the other end that penetrates the insulation box and then protrudes outside the chamber; and a plurality of heat dissipation fins that are provided on the outer surface of the heat pipe.

[0018] Additionally, a protective device is provided inside the insulation box to surround and support the rotational axis of the motor.

[0019] Meanwhile, the motor, insulation box, blower fan, coupling, protective cover and heat dissipation part are integrated and inserted into the chamber through a mounting hole formed on the side of the chamber.

[0020]

[0021] The blower fan unit of the environmental simulation chamber of the present invention, configured as described above, has the advantage of being unaffected by the temperature inside the chamber, as the motor is exposed to the exterior of the environmental simulation chamber. Furthermore, the heat inside the chamber can be prevented from transferring to the motor by the insulation, thereby significantly reducing the impact of the temperature inside the chamber.

[0022] In addition, the coupling connecting the shaft of the blower fan and the rotational axis of the motor and the bearing that rotatably supports the shaft are protected by a protective cover, thereby preventing damage to the coupling or bearing due to external force, foreign substances, or water droplets. In addition, by using the coupling with the rotational axis of the motor, there is the advantage of preventing vibration due to rotational resistance and eccentricity.

[0023] In addition, by mounting a heat dissipation part including a heat absorbing fin, a heat pipe, and a heat dissipation fin on the outside of the protective cover, the heat inside the protective cover is released to the outside of the chamber, which has the advantage of extending the life of the bearing and coupling.

[0024] In addition, since the main elements constituting the invention are integrated and installed through the mounting holes of the chamber, there is an advantage in that they are easy to attach and detach, and broken components can be easily repaired outside the chamber.

[0029]

[0030] Hereinafter, an embodiment of a blower fan unit of an environmental simulation chamber according to the present invention will be described in detail with reference to the attached drawings.

[0031] FIG. 1 and FIG. 2 are perspective views showing a blower fan unit of an environmental simulation chamber according to the present invention, FIG. 3 is a cross-sectional view of a blower fan unit of an environmental simulation chamber according to the present invention, and FIG. 4 is a view showing the blower fan unit shown in FIG. 1 mounted in an environmental simulation chamber.

[0032]

[0033] The blower fan unit according to the present invention is used in an environmental simulation chamber for testing the reliability of parts and products, etc., in a high or low temperature environment, and can be installed and used in a constant temperature and humidity chamber, a CO2 incubator, a battery test chamber, etc., and is installed inside a chamber (C) to circulate air inside the chamber (C) to control the temperature inside the chamber (C).

[0034] The present invention comprises a motor (10), an insulation box (20) to which the motor (10) is coupled on the outer surface and installed on one side of a chamber (C), a blower fan (30) installed inside the chamber (C), a coupling (40) that transmits the rotational force of the motor (10) to the blower fan (30), a protective cover (50) installed on one side of the blower fan (30), and a heat dissipation unit (60) that releases heat inside the protective cover (50) to the outside of the chamber (C).

[0035]

[0036] The above motor (10) is installed on the outer surface of the insulation box (20) and is located outside the chamber (C) when the insulation box (20) is mounted in the chamber (C). At this time, the rotation shaft (11) provided in the motor (10) extends horizontally toward the inside of the chamber (C) and penetrates the insulation box (20) and the protective cover (50).

[0037]

[0038] The above insulation box (20) is filled with insulation (20a) in the internal space and, when installed on one side of the chamber (C), the motor (10) is positioned outside the chamber (C).

[0039] In detail, the insulation box (20) is composed of a body (21) with one side open, and a cover (22) that seals the open side of the body (21) and to which the motor (10) is coupled.

[0040] The above body (21) has an open side in the shape of a square container, and is filled with insulation (20a) on the inside. Since this body (21) is located inside the chamber (C) when the insulation box (20) is coupled to the chamber (C), it is not exposed outside the chamber (C) when installed in the chamber (C).

[0041] In addition, a sealing projection (21a) may be formed on the outer surface of the body (21). Accordingly, when the body (21) is inserted into the chamber (C), the sealing projection (21a) can be in close contact with the corner portion of the chamber (C) around the mounting hole (C1) described later.

[0042] The above cover (22) is formed as a square panel and is tightly fixed to the outer surface of the chamber (C). It is bolted to the outer surface of the chamber (C) around the mounting hole (C1) while being joined to one surface of the body (21). Since this cover (22) is fixed to the outer wall surface of the chamber (C) from the outside of the chamber (C), it is exposed outside of the chamber (C).

[0043] Meanwhile, inside the insulation box (20), a protective device (70) is provided to surround and support the rotational shaft (11) of the motor (10).

[0044] As described above, the inside of the body (21) of the insulation box (20) is filled with insulation (20a), and a protective device (70) is provided to prevent the insulation (20a) from affecting the rotational movement of the rotational shaft (11) of the motor (10) or from causing any other physical / chemical effects.

[0045] In addition, a protective device (70) is provided to support the rotational axis (11) of the motor (10) in a horizontal state and to block heat inside the chamber (C) from flowing toward the motor (10) through the periphery of the rotating rotational axis (11). Accordingly, a sealing ring (71) is provided inside the protective device (70) to tightly fit the outer surface of the rotational axis (11) and prevent the occurrence of a gap.

[0046]

[0047] The above blower fan (30) is configured to include a housing (31), an impeller (32) provided inside the housing (31), and a shaft (33) provided on both sides of the impeller (32).

[0048] The above housing (31) is provided inside the chamber (C) and the impeller (32) is rotatably supported.

[0049] The above impeller (32) rotates to create wind and circulate the air inside the chamber (C).

[0050] The above shaft (33) is provided on both sides of the impeller (32) and passes through both sides of the housing (31).

[0051]

[0052] The above coupling (40) connects the shaft (33) of the blower fan (30) and the rotational shaft (11) of the motor (10) that passes through the insulation box (20) to provide the rotational force of the motor (10) to the shaft (33), thereby causing the impeller (32) to rotate. That is, since the shaft (33) of the blower fan (30) and the rotational shaft (11) of the motor (10) are directly connected by the coupling (40), when the rotational shaft (11) of the motor (10) rotates, the shaft (33) rotates, and the rotation of the shaft (33) causes the impeller (32) to rotate.

[0053]

[0054] The above protective cover (50) is installed on one side of the housing (31) of the blower fan (30) and accommodates the shaft (33) of the blower fan (30) and the rotational axis (11) of the motor (10) that penetrates the insulation box (20) and the coupling (40) inside.

[0055] Meanwhile, a bearing (34) that rotatably supports the rotational axis (11) of the motor (10) is installed on the side of the housing (31) of the blower fan (30). This bearing (34) is housed inside a protective cover (50) together with the shaft (33) of the blower fan (30), the end of the rotational axis (11) of the motor, and the coupling (40).

[0056] That is, the protective cover (50) has one side open to form a space inside, and this open side is installed in close contact with the outer surface of the housing (31) of the blower fan (30), and a shaft (33) penetrating the housing (31) of the blower fan (30), a rotational shaft (11) of the motor (10) penetrating the body (21) of the insulation box (20), a coupling (40) connecting the shaft (33) and the rotational shaft (11), and a bearing (34) supporting the rotational shaft (11) are accommodated inside. Therefore, the components accommodated inside the protective cover (50) are isolated from the internal space of the housing (31).

[0057]

[0058] The above heat dissipation part (60) has one side in close contact with the outer surface of the protective cover (50) and the other side penetrates the insulation box (20) and then protrudes out of the chamber (C), thereby dissipating heat inside the protective cover (50) out of the chamber (C). It is preferable that this heat dissipation part (60) be made of a metal material with good thermal conductivity.

[0059] To explain in more detail, the heat dissipation unit (60) is composed of a heat absorption panel (61), a plurality of heat absorption fins (62) spaced apart from the heat absorption panel (61), a plurality of heat pipes (63) connected to the heat absorption panel (61), and a plurality of heat dissipation fins (64) provided on the outer surface of the heat pipes (63).

[0060] The above heat absorption panel (61) is in close contact with the outer surface of the protective cover (50) and absorbs heat inside the protective cover (50) through the surface of the protective cover (50).

[0061] The above heat-absorbing fins (62) are formed in a number of protruding pieces at close intervals on one surface of the heat-absorbing panel (61).

[0062] The above heat pipe (63) has one end connected to the heat absorption panel (61) and the other end penetrates the insulation box (20) and then protrudes outside the chamber (C). By means of this heat pipe (63), heat inside the protective cover (50) can be transferred outside the chamber (C).

[0063] The above heat dissipation fins (64) are provided in large numbers at close intervals on the outer surface of a plurality of heat pipes (63). Therefore, the heat dissipation effect can be further enhanced.

[0064]

[0065] Meanwhile, the present invention described above can be installed inside the chamber (C) by inserting it into the chamber (C) in a state where all components are integrated, that is, assembled and not disassembled.

[0066] In detail, the motor (10), insulation box (20), blower fan (30), coupling (40), protective cover (50), heat dissipation part (60), and protective gear (70) constituting the present invention are assembled and integrated, and then inserted and mounted into the chamber (C) by pushing them through the mounting hole (C1) formed on the side of the chamber (C), and when disassembling, the assembled and integrated blower fan unit can be pulled out through the mounting hole (C1) to be taken out of the chamber (C). Therefore, the assembly and disassembly of the blower fan unit becomes easy, and when some parts break down and need to be repaired or replaced, the work can be easily removed and performed outside the chamber (C), thereby increasing convenience.

[0067]

[0068] The present invention relates to a blower fan unit of an environmental simulation chamber, and is used when testing the durability and reliability of parts and products and thermal shock, etc. in high or low temperature environments, so it can be used in industries that produce equipment required for laboratories, or in industrial product manufacturers that conduct their own quality control, etc.
