Abstract
The invention relates to a block construction of a diesel generator set, in particular to a heat dissipation structure of a box type diesel generator set. The structure comprises a box body, an inner chamber of which is internally provided with a power generator, a diesel engine and an air inlet duct; the front end of the power generator is provided with an air blower coaxial with the power generator; the air blower is provided with two coaxial impellers which are respectively in a front working chamber and a rear working chamber; the air inlet duct arranged on the front working chamber is arranged at the front end of the air blower and is communicated with the inner chamber of box body; the air inlet duct arranged on the rear working chamber is arranged at the rear end of the air blower and is communicated with the front end of the inner chamber of a power generator shell; the two working chambers share a fan outlet located at the top of the air blower and an air exhausting duct communicated with an air exhausting port at the top of the box body is arranged above the fan outlet. The invention features reasonable heat dissipation path, good heat dissipation effect, simplified inner structure and wiring of the equipment, improved operation reliability and reduced costs.
Description
Technical field
The present invention relates to a kind of modular construction of diesel generating set, specifically is a kind of heat dissipation structure of box type diesel generator set.
Background technique
Silencing type air-cooled diesel generator set generally is that generator set is installed in the box structure, should carry out sound insulation, noise reduction, vibration damping processing, will guarantee that also unit ventilation and heat in case is good; The hot environment reliably working that can require; Because unit endogenous pyrogen air-flow is mixed and disorderly, generally be that the cooling fan by the 220V driven by motor that quantity does not wait is installed in quiet case, owing to consider to install cooling fan; Just need to select suitable position and wind path trend and line arrangement and control; Also to propose very high requirement simultaneously, thereby bring complexity for the design of quiet case, increase the rate of fault of unit the resistance to high temperature of fan motor; Reduce the unit whole reliability, also increased manufacture cost.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of simple in structure, cost is low, operational reliability is high, the heat dissipation structure of box type diesel generator set of good heat dissipation effect.
Institute of the present invention heat dissipation structure of box type diesel generator set includes a casing, is mounted with generator in the cabinets cavity front portion, and the cabinets cavity rear portion is mounted with DENG, and the cabinets cavity rear end is mounted with and is communicated with the inside and outside air inlet duct of casing; Said generator front end is provided with a blower fan with generator coaxle; Said blower fan has two coaxial impellers; Two impellers lay respectively in former and later two active chambers; The intake grill that is positioned at anterior active chamber is positioned at the blower fan front end and communicates with cabinets cavity; The intake grill that is positioned at the active chamber at rear portion is positioned at the blower fan rear end and communicates with generator body intracoelomic cavity front end, two shared fan outlets that are positioned at the blower fan top of active chamber, and the fan outlet top is provided with the air exhaust channel that communicates with casing top exhaust port.
The outlet of leading to cabinets cavity of said air inlet duct has two, and these two outlets lay respectively at both sides, cabinets cavity rear end.
The present invention utilizes alternator shaft to drive two-way blower fan as heat radiation power, and part two-way circulation in device external and the generator housing of radiating airflow in the casing can be dispelled the heat its reasonable heat dissipation path, good heat dissipation effect simultaneously to the equipment inside and outside; Simultaneously, relative traditional heat-dissipating structure, it has reduced the quantity that is provided with of cooling fan, has simplified equipment inner structure and wiring, has improved reliability of operation, has reduced cost.

Fig. 2 is the decomposition texture schematic representation of blower fan of the present invention.
Embodiment
As shown in the figure, this heat dissipation structure of box type diesel generator set includes a casing 1, is mounted with generator 2 in the cabinets cavity front portion, and the cabinets cavity rear portion is mounted with DENG 3, and the cabinets cavity rear end is mounted with and is communicated with the inside and outside air inlet duct 4 of casing; The generator front end is provided with a blower fan 5 with generator coaxle; Blower fan has two coaxial impellers 51; Two impellers lay respectively in former and later two active chambers; The intake grill 52 that is positioned at anterior active chamber is positioned at the blower fan front end and communicates with casing 1 inner chamber; The intake grill 53 that is positioned at the active chamber at rear portion is positioned at the blower fan rear end and communicates with generator 2 housing inner chamber front ends, two shared fan outlets 54 that are positioned at the blower fan top of active chamber, and the fan outlet top is provided with the air exhaust channel 6 that communicates with casing top exhaust port.The outlet 41 of leading to cabinets cavity of air inlet duct 4 has two, and these two outlets lay respectively at both sides, cabinets cavity rear end.
In the working procedure of the present invention; The casing air outside gets into cabinets cavity by air inlet duct 4 from both sides; Air-flow from motor 3 outsides through after be divided into two-way: one road air-flow gets in the generator housing from the radiation hole on generator 2 housings; Dispelled the heat in generator inside, get into the active chamber at blower fans 5 rear portions then from the intake grill 53 of the active chamber that is positioned at the rear portion, upwards discharge by the impeller at blower fan rear portion again; Another road air-flow is outside through generator, and external cavity heat radiation back is got into the anterior active chamber of blower fan from the intake grill 52 that is positioned at anterior active chamber, is upwards discharged by the anterior impeller of blower fan again.
