Abstract
The utility model relates to a boiling type self-circulation steam guiding water cooling gasoline engine, which comprises a cylinder body, a cylinder head and a water box, wherein the radial periphery of the cylinder body is provided with the water box and the cylinder head is provided with air cooling radiating fins. A position which is higher than the water box is provided with an auxiliary water box which is communicated with the water box through a steam guiding pipe and a cold water reverse flow pipe, forming a self-circulation water cooling system. The problem of water freezing for the auxiliary water box for working in low temperature environment is solved through steam from the water box. Cooling water can be ensured to be supplemented to the water box and cooling for the gasoline engine can be realized. Temperature can be controlled within ceiling temperature. Compared with the existing water cooling gasoline engine, the utility model has the advantages of simple structure, low cost and high value function.
Description
Technical field
The utility model relates to a kind of water-cooled petrol engine, refers to a kind of boiling type self circulation steam guidance water-cooled gasoline engine especially.
Background technique
A kind of motor tricycle boiling type water cooled engine is arranged, and it is that radial outer periphery in cylinder block is provided with water tank, and the casing and the cylinder block of water tank are located by connecting, and are water cavity between the outer wall of cabinet wall and cylinder block.Its casing top is provided with the open type water intake.In the course of the work, cylinder head is to dispel the heat by the wind-cooling heat dissipating sheet, and cylinder block is to dispel the heat by water-cooling pattern.Under atmospheric pressure state, the boiling water temperature in the water tank is no more than 100 ℃.Cooling to motor is played a role, and is a kind of simple in structure and effective type of cooling.But also there is the technical problem that waits to solve in this type of cooling.1, a large amount of steam that boiled water produced cause the water in the water tank constantly to reduce, and for guaranteeing the lasting cooling to motor, must replenish cooling water to water tank at short notice.
2, imagination increases a secondary water tank, be implemented as the task of the unidirectional water supply of water tank, to prolong the time lag of replenishing cooling water to water tank, thing followed problem then is: if at subzero tens degree, and even when moving in the cold environment of subzero tens degree, serious icing phenomenon can appear in the water in the secondary water tank, causes secondary water tank forfeiture water supply function.
The model utility content
The purpose of this utility model just provides a kind of boiling type self-loopa steam water conservancy diversion water-cooled petrol engine, and the water of the secondary water tank that is increased can not freezed in sub-zero temperature environmental work, and can guarantee to replenish cooling water to water tank, realizes the cooling to petrol engine.
For realizing described purpose, the utility model adopts following technological scheme: comprise cylinder block, cylinder head and water tank, the radial outer periphery of cylinder block is provided with water tank, cylinder head is provided with the wind-cooling heat dissipating sheet.And being provided with a secondary water tank, its upper end is provided with case lid and steam discharger.The top of water tank is communicated with by the top of steam honeycomb duct and secondary water tank, and the bottom of water tank is communicated with by the bottom of cold water return tube and secondary water tank.
On the cold water return tube, be provided with control valve.
In the use, at first answer the case lid of open auxiliary water tank, inject cooling water in secondary water tank, cooling water enters water tank through the cold water return tube.After petrol engine started, the heat that cylinder block produced made the water boiling in the water tank, and the steam of generation enters secondary water tank through the steam honeycomb duct.Steam promptly is the process that condenses into water in the process of secondary water tank heat radiation, and the water through dischargeing heat enters through water tank bottom through the bottom of cold water return tube from secondary water tank again.Cylinder body in the water tank is continued cooling, and the type of cooling of this self-circulation type is through boiling, and------------cooling---process of boiling of backflowing is the process of a circulating cold and hot exchange to steam to coagulate water.It has effectively prevented water freezing in sub-zero temperature environmental work in the secondary water tank by the entrained heat of steam, carries out cold and hot exchange simultaneously, guarantees to replenish cooling water, realize the cooling to petrol engine to water tank.

Embodiment
With reference to Fig. 1.This is an embodiment of boiling type self circulation steam guidance water-cooled gasoline engine, is provided with in the radial outer periphery of horizontal petrol engine and is provided with the wind-cooling heat dissipating sheet on water tank 1, the cylinder head.Be provided with a secondary water tank 8 in the position that is higher than water tank, and be communicated with the upper end of water tank and secondary water tank, be communicated with by the bottom of cold water return tube 6 with water tank and secondary water tank by steam honeycomb duct 11.The relative height of water tank, the height of secondary water tank bottom should satisfy two conditions: promptly 1, the highest water level in the water tank should flood cylinder block; 2, in the secondary water tank certain water should be arranged.The upper end of secondary water tank is provided with case lid 10 and steam discharger 9.On the cold water return tube, be provided with valve 7.Be provided with end cap 2,5, one in the water tank both sides, technologic requirement, the 2nd, used for removing in the water tank internal water impurity.Be provided with water outlet 3 in the water tank bottom, usually for sewage effluent and cleaning water tank.During sewage effluent, close the valve 7 on the cold water return tube earlier, open water outlet 3 then, behind the sewage effluent, open valve 7 again, water tank is washed with the water in the secondary water tank.The effect of steam spill pipe 9 is that secondary water tank and water tank are guaranteed a comparatively stable working pressure, when vapor pressure is excessive, can discharge automatically by the steam spill pipe, to guarantee normal cold and hot exchange.
With reference to Fig. 2.This is that cylinder block is a kind of boiling type self circulation steam guidance water-cooled gasoline engine under the vertical state, and other structure is identical with embodiment 1, repeats no more.
Claims (2)
1, a kind of boiling type self circulation steam guidance water-cooled gasoline engine, comprise cylinder block, cylinder head, water tank, the radial outer periphery of cylinder block is provided with water tank, cylinder head is provided with the wind-cooling heat dissipating sheet, it is characterized in that: be provided with a secondary water tank (8), secondary water tank upper end is provided with case lid (10) and steam discharger (9), the top of water tank is communicated with by the top of steam honeycomb duct (11) and secondary water tank, and the bottom of water tank is communicated with by the bottom of cold water return tube (6) and secondary water tank.
