DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following clearly and completely describes the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present disclosure. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

[0021] The present disclosure aims to provide an air-cooled diesel generator to solve the problem in the prior art and to improve the heat dissipation performance.

[0022] To make the above objects, features, and advantages of the present disclosure more apparent, the present disclosure will be described in further detail below with reference to the accompanying drawings and detailed description of the embodiments.

[0023] The present disclosure provides an air-cooled diesel generator, which is adapt for a silent rainproof box for a high-power air-cooled diesel generator set with a V-shaped cylinder. As shown in FIG. 1, the air-cooled diesel generator comprises a box body 1 and a plurality of components provided in the box body 1, and an outside of each component is provided with a separate housing; a main air inlet 5 and a main air outlet 4 are formed in the box body 1; a sub-air inlet and a sub-air outlet are formed in each housing, each sub-air outlet communicates with the main air outlet 4 through an air duct 7, and each sub-air inlet is provided with an air guide device 6.

[0024] Where each component is correspondingly provided with a separate air duct 7 to convey hot air in the housing, the heat interference among the components is small, and the air guide device 6 is provided as a power source to make external air, air in the box body 1, and air in the housing circulate, to improve the heat dissipation efficiency of the device, and thus, the air-cooled diesel generator provided by the present disclosure has better heat dissipation performance.

[0025] Further, in order to prevent impurity particles from entering the box body 1 through the main air inlet 5 and the main air outlet 4, the main air inlet 5 and the main air outlet 4 are each provided with an isolation net.

[0026] Further, in order to prevent rainwater from entering the box body 1 through the main air inlet 5 and the main air outlet 4, the main air inlet 5 and the main air outlet 4 are each provided with a louver.

[0027] Further, in order to prevent excessive noise, the box body 1 is provided with sound-absorbing cotton, and the sound-absorbing cotton can absorb noise generated by the generator set.

[0028] Further, the maximum size of a hole on the isolation net is 12 mm to filter impurities with size larger than 12 mm.

[0029] Further, the air guide device 6 is a draught fan, and the draught fan is used to introduce the air in the box body 1 into the housing and exhaust the air in the housing out of the box body 1 through the air duct 7.

[0030] Further, the air-cooled diesel generator comprises at least two components, and the two components are a diesel engine 2 and a generator 3 respectively.

[0031] Further, in order to enhance anti-interference capability among the components, the air duct 7 is made of a thermal insulation material, and the air duct 7 is fixed in the box body 1 through a support frame.

[0032] Further, a number of the main air inlets is two.

[0033] Specific examples are used in the present disclosure to set forth the principles and embodiments of the present disclosure. The above description of the embodiments is merely used to help understand the method of the present disclosure and its core thought; and meanwhile, for a person of ordinary skill in the art, changes may be made in both specific embodiments and scope of application in accordance with the thought of the present disclosure.
