Abstract
The utility model relates to a cylinder-head bottom drilling cooling structure which belongs to a sealing device of a combustion engine and consists of an integrative cylinder-head body. The utility model is characterized in that at least two groups of cooling water via-holes are transversely processed on the water channel wall on the bottom of the cylinder-head body and the cooling water via-holes are distributed in a cross shape. The utility model makes the improvements on existing techniques. Because the cooling water via-holes are transversely processed on bottom of the water channel wall 2 of the cylinder-head body 1, the utility model therefore changes the direction of the cooling water in the water channel, changes unidirectional recurrent type cooling into multi-directional circulating type cooling in a manner of concentrated forced cooling from around the water channel to the centre thereof. Thus, the cooling effect of the cooling water is enhanced and the cooling of the lower part of an airway is reinforced and therefore the service life of the cylinder-head body.
Description
Technical field
The utility model belongs to the seal arrangement of combustion engine, specifically is a kind of cylinder head bottom hole cooling structure.
Background technique
Cylinder head is one of requisite parts on the diesel engine, mainly be that casting forms, be subjected to the influence of traditional design thinking, the cooling water runner of present cylinder head bottom is a semi-closed structure, cause the unidirectional return formula of cooling water in the cylinder to flow like this, mobile poor, temperature reduction performance reduces, cause the temperature of cylinder head bottom heating surface too high, seminess takes place in bottom easily, thereby influences the raising of diesel engine overall performance, shorten cylinder head working life, for this reason, the technician is being devoted to air cylinder head structure is improved always, to improve the effect of cylinder.
The model utility content
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, under the situation that does not influence existing cylinder head installation dimension, provide a kind of cylinder head to improve to prior art, can improve the cooling effect of cooling water, the bottom is difficult for taking place seminess, the cylinder head bottom hole cooling structure of long service life.
For achieving the above object, the utility model is achieved through the following technical solutions:
Be a kind of cylinder head bottom hole cooling structure, comprise integral type cylinder lid, the present technique main points are laterally to be processed with at least 2 group cooling water through holes, the crosswise distribution of cooling water through hole on the waterway wall of this cylinder lid bottom.
For ease of casting or machining, described cooling water through hole line stretcher is vertical mutually.
After the utility model carries out above-mentioned improvement to prior art, owing on the waterway wall of cylinder lid bottom, laterally be processed with the cooling water through hole, therefore changed the trend of cooling water in the water channel, by concentrating pressure to cool off toward the middle part around the water channel, strengthened the cooling effect of cooling water, strengthen the cooling of air flue bottom, therefore also prolonged the working life of cylinder lid.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1: the utility model embodiment sectional structure schematic representation.
The A-A of Fig. 2: Fig. 1 is to the sectional structure schematic representation.
Embodiment
As shown in Figure 1, this cylinder head bottom hole cooling structure comprises integral type cylinder lid 1, and the present technique main points are laterally to be processed with at least 2 group cooling water through holes 3, the 3 crosswise distributions of cooling water through hole on the waterway wall 2 of this cylinder lid 1 bottom.
For ease of casting or machining, described cooling water through hole 3 line stretchers are vertical mutually.
After the utility model carries out above-mentioned improvement to prior art, because waterway wall 2 bottom transverse at cylinder lid 1 are processed with the cooling water through hole, therefore changed the trend of cooling water in the water channel, become unidirectional return formula and be cooled to multidirectional circulating cooling, by concentrating pressure to cool off toward the middle part around the water channel, strengthen the cooling effect of cooling water, strengthened the cooling of air flue bottom, therefore also prolonged the working life of cylinder lid.
Claims (2)
1. a cylinder head bottom hole cooling structure comprises integral type cylinder lid, it is characterized in that laterally being processed with at least 2 group cooling water through holes, the crosswise distribution of cooling water through hole on the waterway wall of this cylinder lid bottom.
2. cylinder head bottom hole cooling structure according to claim 1 is characterized in that cooling water through hole line stretcher is vertical mutually.
