Abstract
The invention relates to a small circulation structure for a cooling system of an automobile engine, which comprises a thermolator consisting of a thermolator seat and a thermolator cover, wherein the thermolator seat is provided with an inlet of the thermolator seat and a heating ventilation branch; the thermolator cover is provided with an outlet connected with a radiator and a water inlet pipe branch connected with the engine; a small circulation channel of the thermolator seat and a small circulation channel of the thermolator cover are arranged between the heating ventilation branch of the thermolator seat and the water inlet pipe branch of the thermolator cover to form a small circulation channel consisting of the inlet of the thermolator seat, the heating ventilation branch, the small circulation channel of the thermolator seat, the small circulation channel of the thermolator cover and the water inlet pipe branch; and during cold start, cooling liquid passes through the small circulation channel and enters the water inlet pipe of the engine from a water jacket outlet of a cylinder cover. The traditional small circulation externally connected hose is arranged onto the thermolator seat and the thermolator cover to form an integrated structure, so the structure is simplified, solves the problems of easy aging and invalidation and easy water leakage of the hose, improves the reliability of small circulation, and ensures the performance of cold start of the engine.
Description
Technical field
The invention belongs to the car engine cooling system technology, be specifically related to a kind of small circulation structure for cooling system of automobile engine.
Background technique
Reliable, stable, durable for guaranteeing engine operation, need cooling system to remain in the certain temperature range.In the motor process that starts cold conditions, coolant temperature is low, and thermoregulator cuts out, and at this moment cooling liquid is directly got back to the circulation of engine interior water jacket through the short circle passage without radiator, and cooling liquid is heated up rapidly; This is a short circle.Work as COOLANT TEMPERATURE, thermoregulator is opened automatically, and cooling liquid enters radiator passage through thermoregulator, gets back to engine interior after cooling by radiator, makes the motor cooling; This is major cycle.
If there is not short circle, after cooling off through radiator, the cooling liquid that temperature is lower gets back to motor, and its temperature can not raise for a long time, and motor is running at low temperatures for a long time also, reduces engine performance.
The short circle passage uses clip connected on thermolator base HVAC arm by an end of a flexible pipe generally speaking, the other end covers on the intake pipe arm at thermoregulator with clip connected, cooling liquid is through thermolator base inlet, HVAC arm, flexible pipe, intake pipe arm during cold start-up, enter the water inflow of the engine pipe, get back to the engine interior water jacket.Because need flexible pipe is installed, increased assembly process, increased cost, the easy ageing failure of flexible pipe, the leakproof of clip fastening means is unreliable, easily leaks, and then influences the engine cold-start performance.
Summary of the invention
At the deficiencies in the prior art, propose a kind of simple in structure, the practical and reliable small circulation structure for cooling system of automobile engine.
This small circulation structure for cooling system of automobile engine comprises the thermoregulator that is combined into by thermolator base and thermoregulator lid, and thermolator base inlet and HVAC arm are arranged on the thermolator base, and thermoregulator covers the outlet that connects radiator and the intake pipe arm of sending and receiving motivation; It is characterized in that: between the intake pipe arm of the HVAC arm of thermolator base and thermoregulator lid, have thermolator base short circle passage and thermoregulator lid short circle passage, thermolator base short circle passage and thermoregulator lid short circle passage are interconnected, the short circle passage that formation is made up of thermolator base inlet, HVAC arm, thermolator base short circle passage, thermoregulator lid short circle passage, intake pipe arm, when cold start-up, cooling liquid enters the water inflow of the engine pipe by described short circle passage from the outlet of cylinder head water cover.
Traditional short circle external hose is simplified to thermolator base to this structure and thermoregulator covers the formation integral structure, saved the short circle external hose, simplify the structure, reduced the flexible pipe assembly process, reduce cost, the problem of solved the easy ageing failure of flexible pipe, easily leaking, and then improved the reliability of short circle, guaranteed the engine cold-start performance.

The 3-thermoregulator
Embodiment
Referring to Fig. 1, casting thermolator base short circle passage 13 on the outer wall between the intake pipe arm 22 of the HVAC arm 12 of thermolator base 1 and thermoregulator lid 2 (13 with the moulding of thermolator base integrally casting) and thermoregulator lid short circle passage 21 (21 cover integrally casting moulding with thermoregulator), 13 and 21 connect, 13 are communicated with the top of HVAC arm 12,21 are communicated with the top of intake pipe arm 22, like this, formation is by thermolator base inlet 11, thermolator base short circle passage 13, thermoregulator lid short circle passage 21, the short circle passage that intake pipe arm 22 is formed, when cold start-up, cryogenic liquid flows into thermolator base 1 from the cylinder cap water jacket, through thermolator base inlet 11, thermolator base short circle passage 13, thermoregulator lid short circle passage 21, intake pipe arm 22, the inflow engine intake pipe, enter the engine interior circulation by intake pipe again, without the radiator cooling, reach the purpose that motor is heated up rapidly.
During major cycle, thermoregulator 3 is opened automatically, and high temperature coolant enters the engine interior circulation again after thermoregulator directly enters the radiator cooling, reach the cooling purpose.
