Embodiment 1

[0049] see Figure 1 to Figure 5 , a thermostat system with a special inlet arrangement for commercial vehicles, including a thermostat housing 1 connected to each other, an oil cooler module 2, a guide pipe 5, and a body coolant hole 22 opened in the oil cooler module 2 A thermostat 3 is provided near the oil cooler module 2 in the thermostat housing 1, and the paraffin temperature sensing part 4 in the thermostat 3 and the small circulation inlet 21 in the oil cooler module 2 or The large circulation inlet 11 in the thermostat housing 1 is connected; the thermostat 3 includes a back seat 31, a paraffin temperature sensing part 4 and a valve body 32, and the valve body 32 is arranged to slide back and forth along the paraffin temperature sensing part 4; The periphery of the back seat 31 is connected to the inner wall of the thermostat housing 1, the middle part of the back seat 31 is connected to one end of the paraffin temperature sensing part 4, and the other end of the par...

Embodiment 2

[0054] Basic content is the same as embodiment 1, the difference is:

[0055] Structurally: when the valve body 32 slides along the front of the paraffin temperature sensing part 4 to the end point, the bottom of the valve body 32 is in close cooperation with the small circulation inlet 21; when the valve body 32 slides to the end point along the paraffin temperature sensing part 4, The bottom of 32 is in close cooperation with large circulation inlet 11.

[0056] When in use: when the thermostat 3 is opened, it means that when the valve body 32 slides along the front of the paraffin temperature sensing part 4 to the end point, the bottom front end 321 of the valve body 32 closes the small circulation inlet 21, and at the same time, the bottom rear end 322 of the valve body 32 is released. The closure of the large circulation inlet 11; the closure of the thermostat 3 refers to: when the valve body 32 slides to the end point along the paraffin temperature sensing part 4, the fr...

Embodiment 3

[0058] Basic content is the same as embodiment 1, the difference is:

[0059] The guide tube 5 is set higher than the small circulation inlet 21, and the small circulation inlet 21 communicates with the paraffin temperature sensing part 4 after passing through the module inner cavity 23, the module outer cavity 24, and the housing cavity 12 in sequence. The large circulation inlet 11 communicates with the paraffin temperature sensing part 4 after passing through the shell cavity 12, the large circulation inlet 11 is set lower than the draft tube 5, and the horizontal distance between the large circulation inlet 11 and the cooling liquid hole 22 of the body is larger than the small one. The horizontal distance between the circulation inlet 21 and the coolant hole 22 of the machine body.

Abstract

The invention discloses a temperature regulator system adopting special inlet arrangement for a commercial vehicle. The temperature regulator system comprises a temperature regulator housing, an engine oil cooler module, a temperature regulator, a guide tube and a machine body coolant hole; the temperature regulator comprises a rear seat, a paraffin temperature sensing part and a valve body; the paraffin temperature sensing part sequentially passes through the guide tube and the machine body coolant hole and communicates with a coolant in a machine body. During use, when a minor cycle is opened, the paraffin temperature sensing part simultaneously senses temperatures of the coolant from an inlet of the minor cycle and the coolant from the guide tube; when the minor cycle is closed, the paraffin temperature sensing part simultaneously senses the temperatures of the coolant from an outlet of a major cycle and the coolant from the guide tube. With the adoption of the design, then the minor cycle is closed, the coolant in the machine body can be subjected to temperature sensing, the temperature sensing accuracy is improved, and frequent opening and closing and control delay of the temperature regulator can be avoided.

Description

technical field [0001] The invention relates to a thermostat system for a vehicle, in particular to a thermostat system with a special inlet arrangement for a commercial vehicle and a temperature sensing method thereof, which is particularly suitable for realizing the sensing of the coolant in the body when the small circulation is closed. temperature, improve the accuracy of temperature sensing. Background technique [0002] The arrangement of the thermostat in the engine is mainly divided into inlet arrangement and outlet arrangement. The opening and closing of the thermostat adopting the inlet arrangement will not cause large fluctuations in the temperature of the coolant in the engine block, which can ensure the cooling of the engine. When running smoothly, there will be no fluctuations, and the warm-up time of the engine can be shortened. However, the inlet of the thermostat is arranged. When the large cycle is turned on, the liquid temperature it perceives is the temp...
