Abstract
The utility model relates to a heat dissipating back cover of the single cylinder diesel used for solving the problem that the engine oil temperature of the diesel of single cylinder and large cylinder diameter and high power is too high and the utility model belongs to the technology field of power device. The utility model mainly adopts a pad and a cover plate positioned on the back cover body and a back cover body which are assembled into integration. The back cover body is positioned with an oil channel of maze type formed by the separating ribs of fish bone shape. The exterior surface of the back cover body is provided with rib plates used for heat dissipating to the air. The utility model has simple, compact and reasonable structure. The lubricate engine oil can be introduced to the interlayer of the heat dissipating back cover and thus the flowing path of the engine oil in the back cover is lengthened and the contacting area of the engine oil and the back cover is increased. The engine oil flows through the oil channel of maze type of the heat dissipating back cover to transmit a great amount of heat to the back cover. The diesel has windward cooling in running and the heat dissipating effect is better and the temperature of the engine oil can be generally reduced more than 15 degree C.
Description
Technical field
The utility model relates to a kind of heat radiation bonnet of single cylinder diesel, is used to solve the too high problem of oil temperature of single cylinder vat caliber high power diesel engine, belongs to field of power equipment technology.
Background technique
The diesel engine bonnet is a part as single cylinder diesel, and its effect is the ear end face of capping crankcase, by the disassemble or assemble bonnet, the ear end face of crankcase is opened or closed, so that the component in the dismounting crankcase.Before the utility model was made, the bonnet of diesel engine was a typical lid shape part, only plays the effect of capping, does not have the heat sinking function that reduces the diesel engine oil temperature.
Technology contents
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provides a kind of simple, compact and reasonable for structure; A large amount of heats can be passed to bonnet, make diesel engine that the cooling of facining the wind be arranged under steam, thereby can reduce bavin machine oil temperature, the heat radiation bonnet of the single cylinder diesel that radiating effect obviously improves.
Main solution of the present utility model is achieved in that
The utility model mainly adopts installs pad 3, cover plate 2 on bonnet body 4, it is combined into one.Make mazy type oil duct 5 on bonnet body 4, mazy type oil duct 5 adopts fishbone shape muscles to constitute, and on bonnet body 4 outer surfaces fin 6 is set and dispels the heat to air.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Owing to lubricating oil can be introduced in the heat radiation bonnet interlayer, make machine oil flow path in bonnet extend, can increase the area of contact of machine oil and bonnet, machine oil flows through in the mazy type oil duct of heat radiation bonnet, a large amount of heats has been passed to bonnet, diesel engine has the cooling of facining the wind under steam, and better heat-radiation effect generally can reduce oil temperature more than 15 ℃.

Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model bonnet body left view.
Fig. 3 is the utility model bonnet body right elevation.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly is made up of screw 1, cover plate 2, pad 3, bonnet body 4, mazy type oil duct 5, fin 6 etc.Pad 3, cover plate 2 are installed in employing on bonnet body 4, by screw 1 fastening becoming one.Make mazy type oil duct 5 on bonnet body 4, mazy type oil duct 5 adopts fishbone shape muscles to constitute, and on bonnet body 4 outer surfaces fin 6 is set and dispels the heat to air.
Working principle of the present utility model and working procedure:
The utility model is that the lubricant oil with pressure of diesel engine is introduced in the heat radiation bonnet interlayer of being made by aluminum casting, makes machine oil through mazy type oil duct flow path lengthening in the heat radiation bonnet, and the waiting time is also longer in the heat radiation bonnet relatively.The mazy type oil duct is to adopt fishbone shape muscle to form simultaneously, has increased the area of contact of machine oil and bonnet, and machine oil contacts with the heat radiation bonnet in flowing fully like this.The machine oil band the heat that distributes in the diesel engine work to machine oil, in the mazy type oil duct of heat radiation bonnet, flow through, by contacting of longer distance and long period with bonnet, a large amount of heats has been passed to bonnet, and the bonnet body adopts aluminum casting to make, and its outer surface cloth is equipped with and helps sheet to dispel the heat to air.As diesel engine is during as power train in vehicle application, in travelling owing to the cooling of facining the wind is arranged, the better heat-radiation effect of heat radiation bonnet.
The utility model also has the special function that reduces the diesel engine oil temperature except the function with common bonnet, and obvious through experimental test proof radiating effect, generally can reduce oil temperature more than 15 ℃.
Claims (3)
1. the heat radiation bonnet of a single cylinder diesel comprises bonnet body (4), it is characterized in that adopting at bonnet body (4) going up installation pad (3), cover plate (2), and it is combined into one.
