Detailed description of the invention
The attached drawing constituted part of this application is used to provide a further understanding of the present invention, the utility model Illustrative embodiments and their description are not constituteed improper limits to the present invention for explaining the utility model.In attached drawing In:
Fig. 1 is the structural schematic diagram of the embodiment one of frequency converter according to the present utility model;
Fig. 2 is the structural schematic diagram of the embodiment two of frequency converter according to the present utility model.
Specific embodiment
For the purpose of this utility model, technical solution and advantage is more clearly understood, below with reference to embodiment and attached Figure, is described in further details the utility model.Here, the exemplary embodiment and its explanation of the utility model are for solving The utility model is released, but is not intended to limit the scope of the present invention.
In existing radiating subassembly, heat dissipation wind channel part also includes heat dissipation wind channel 11 and is formed in heat dissipation wind channel 11 substantially First end air inlet 12, and be formed in the air outlet 13 of the second end of heat dissipation wind channel 11.It can be arranged at air inlet 12 One big fan imports air-flow, and a small fan export air-flow can be arranged at air outlet 13.
It finds after study, when heat dissipation wind channel 11 is larger, small fan forms vacuum effect deficiency, and it is suitable also to will affect air-flow Channel Group is logical.At this moment, big fan air-flow is too strong, and preposition small fan flow velocity is too low, and the air quantity poured in from entrance is exported greater than small fan Air quantity, the presence of small fan also partial occlusion exhaust outlet influences airflow smooth circulation, causes the whole gas velocity to spend slowly, Influence overall heat exchange.
Based on the above issues, in the technical solution of the utility model, small fan is cancelled, also increases air outlet, is made Air outlet is more convenient for air draft.As shown in Figure 1, in the technical solution of embodiment one, radiating subassembly include heat dissipation wind channel part and Fan part 20, heat dissipation wind channel part are used to treat the element radiating of heat dissipation.Heat dissipation wind channel part includes heat dissipation wind channel 11 and is formed in The air inlet 12 of the first end of heat dissipation wind channel 11, and it is formed in the air outlet 13 of the second end of heat dissipation wind channel 11, air outlet 13 Form opposite outwardly extending first flaring structure of heat dissipation wind channel 11.Fan part 20 is correspondingly arranged with air inlet 12, for into It divulges information in air port 12.
Using the technical solution of the utility model, the fan being arranged at air outlet 13 is eliminated, only sets fan part 20 It sets in position corresponding with air inlet 12, reduces and go out wind resistance at air outlet 13.Meanwhile also by air outlet 13 formed to First flaring structure of outer extension reduces by 13 inner wall of air outlet for air-flow so that air-flow is more convenient for being discharged from air outlet 13 Resistance, so that heat dissipation wind velocity lift, and then improve radiating efficiency.
As a preferred embodiment, as shown in Figure 1, air inlet 12 to form opposite heat dissipation wind channel 11 outwardly extending Second flaring structure.Since the wind of the first fan part 20 blowout can have expansion trend with the flowing of air-flow, and 11 shape of air inlet At flaring structure be then conducive to gather the air-flow of the first fan part 20 blowout, prevent air-flow from being formed in corner and be vortexed and stop. In addition, according to continuity equation in hydrodynamics, the area of the air intake surface of air inlet 11 is since air inlet 11 is flaring structure V1, wind speed A1, the area of the outlet air surface of air inlet 11 is V2, wind speed A2, i.e. V1A1=V2A2, due to area A1 > A2, then It will lead to V1 < V2.I.e. when the first fan part 20 blows to the air intake surface of air inlet 11, speed is smaller, after air inlet 11, just Meeting improves radiating efficiency so that wind velocity lift.
Optionally, in the technical solution of embodiment one, radiating subassembly further includes radiating fin, for being arranged wait radiate Element on, heat dissipation wind channel part be arranged on radiating fin.Heat dissipation wind channel can be cooperated by radiating fin with increasing heat radiation area Part uses, and helps to improve radiating efficiency.
As a preferred embodiment, as shown in Figure 1, in the technical solution of embodiment one, radiating subassembly includes First grid 41, the first grid 41 are arranged on air outlet 13, can effectively the anti-sundries of insect prevention enter, enhance safety.
Under normal conditions, due to there is the presence of fan part 20, the anti-sundries of insect prevention can be played the role of and entered.But in order into One step enhances the effect that the anti-sundries of insect prevention enters, as shown in Figure 1, in the technical solution of embodiment one, radiating subassembly further includes Second grid 42, the second grid 42 are arranged on air inlet 12.
As an optional embodiment, in the technical solution of embodiment one, the section of air inlet 12 and air outlet 13 For inclined-plane.As shown in Figure 1, air inlet 12 is formed by the baffle being obliquely installed, the baffle is relative to horizontal-extending heat dissipation wind channel 11 angled α settings.Optionally, air outlet 13 is also formed by the baffle being obliquely installed, which dissipates relative to horizontal-extending The angled β of hot-flow flue 11 setting.Preferably, angle [alpha] and β need to be adjusted by actual conditions.
As other optional embodiments, it is also feasible that the section of air duct part 10, which is curved surface,.
Fig. 2 shows the embodiment two of the radiating subassembly of the utility model, the technical solutions and embodiment one of embodiment two Technical solution compare, difference be, in the technical solution of embodiment two, radiating subassembly further includes ventilation air duct part 30, Ventilation air duct part 30 is connected between fan part 20 and air inlet 12.Directly fan part 20 can be produced by ventilation air duct part 30 Anger circulates into air inlet 12, guarantees the wind speed of air-flow.
The utility model additionally provides a kind of frequency converter, which uses above-mentioned radiating subassembly.It is dissipated using above-mentioned The radiating efficiency of frequency converter can be improved in the frequency converter of hot component, guarantees that frequency converter is run with security and stability.
The frequency converter of the utility model includes electric heat elements 50, and heat dissipation wind channel part is corresponding with electric heat elements 50 to be set It sets, for radiating to electric heat elements 50.When in use, electric heat elements 50 are sufficiently dissipated by heat dissipation wind channel part Heat, to guarantee the stable operation of frequency converter.
Optionally, frequency converter further includes electrical appliance kit 60, and electric heat elements 50 and heat dissipation wind channel part are arranged in electrical appliance kit 60 Interior, air inlet 12 and air outlet 13 extend to the surface of electrical appliance kit 60.
