Abstract
The utility model discloses a simple and feasible independent air duct structure, which comprises a radiator, an air inlet, an air outlet and a PCBA board, wherein the air inlet is just opposite to one end of the radiator, and a wind shielding mechanism is arranged between the two ends of the radiator and the air inlet and the air outlet; the utility model provides a current wind channel structure expensive complicated, need the problem that the die sinking could realize.
Description
Technical Field
The utility model belongs to the technical field of the converter, concretely relates to simple and feasible independent wind channel structure.
Background
The service environment of servo driver, converter exists a large amount of dust, metal fillings, greasy dirt, can blow or convulsions through the fan and bring into the machine, makes the electrical components short circuit in the machine and stop working, and serious a bit can lead to the ann rule distance not enough, makes the machine explode the machine. Therefore, the air duct must be separated from the internal components and devices to form an independent air duct in the design stage. The design of the existing independent air duct usually adopts two forms of aluminum alloy die casting or plastic injection molding, and although the two structures can well realize the independence of the air duct, the two structures are complex and expensive and can be realized only by opening the die.
In the prior art, a frequency converter with an independent air duct, such as that provided by chinese patent publication No. CN208424172U, includes a reactor, a rectifying radiator, an inverting radiator, a capacitor bank, a fan, an independent air duct region, an upper control region, a first device mounting region and a second device mounting region disposed at two sides of the independent air duct region, the independent air duct region includes three independent sections and a tail junction region; above-mentioned technical scheme sets up three independent wind channel and solves the problem, but three independent wind channel occupation space is big, and the cost will be high.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a simple and feasible independent wind channel structure to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
a simple and feasible independent air duct structure, comprising:
a radiator, an air inlet, an air outlet and a PCBA board,
the air inlet is opposite to one end of the radiator, and a wind shielding mechanism is arranged between the two ends of the radiator and the air inlet and the air outlet.
Preferably, the wind shielding mechanism is a wind shielding strip which is arranged on the side edge of the end part of the radiator close to the PCBA board.
Preferably, a fan is arranged at the air outlet and is opposite to the radiator.
Compared with the prior art, the beneficial effects of the utility model are that: adopt the fan convulsions, can be on fine assurance heat dissipation basis, according to the trend of distinguished and admirable, ingenious utilization wind gap and the strip that keeps out the wind, keep off distinguished and admirable in radiator tooth department, and can not get into the PCBA board region that has circuit and electronic components, solved current wind channel structure expensive complicated, need the die sinking problem that can realize.
Drawings
FIG. 1 is a schematic view of an embodiment of the present invention;
fig. 2 is a rear view of the present invention.
In the figure: 1 radiator, 2 air intakes, 3 air outlets, 4 PCBA boards, 5 weather strips, 6 fans.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution:
a simple and feasible independent air duct structure comprises a radiator 1, an air inlet 2, an air outlet 3 and a PCBA board 4, wherein the air inlet 2 is over against one end of the radiator 1, and a wind shielding mechanism is arranged between two ends of the radiator 1 and the air inlet 2 and the air outlet 3;
the wind shielding mechanism is a wind shielding strip 5 and is arranged on the side edge of the end part of the radiator 1 close to the PCBA board 4. And a fan 6 is arranged at the air outlet 3, and the fan 6 is opposite to the radiator 1.
As shown in figure 1, in the device, air enters from the air inlet, passes through the tooth sheets of the radiator 1, takes away heat, and then passes through the fan 6 to be discharged from the air outlet 3. Wherein, the air inlet 2 is over against the fins of the radiator 1, and between the air inlet 2 and the radiator 1, the wind-shielding strip 5 is used to lead the wind flow to only go away from the fins of the radiator 1 and not to enter the PCBA board of the box body; at air outlet 3, fan 6 is just right with 1 tooth of radiator, take wind out from 1 tooth of radiator, the wind current is by 3 outflow boxes of air outlet, and the air outlet is opened very greatly, can guarantee the quick outflow box of the wind of taking out, also have weather strip 5 simultaneously between fan 6 and radiator 1, prevent that the wind backward flow of taking out from getting into the box, thereby form the design of independent wind channel, this simple structure is reliable, install and remove the convenience, do not increase too much cost, do not increase the weight of machine self.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
