Abstract
An electronic thermostat comprises an inductor assembly, a valve, a cavity assembly and a socket assembly, wherein, the inductor assembly comprises a push rod, a gland, a sealing ring, a rubber tube, a body and a wax pill, and the electronic thermostat is further provided with an electric heating element assembly. The electric heating element assembly comprises an electric heating element, a guide wire and a shank, the electric heating element is arranged in a wax pill cavity, the shank is exposed at the outside of the body, the guide wire of the electric heating element is led out of the shank, the shank, the guide wire and the electric heating element are connected to a whole body by injection molding; and a sealing washer is arranged at the junction of the electric heating element assembly and the body. The guide wire is connected with an insert which is connected on the socket assembly outside the cavity after being led out of the shank. The electronic thermostat has the advantages that the electronic thermostat can reduce the oil consumption, reduce the emissions of CO, HC and fume and control the emissions of nitrogen oxides.
Description
Technical field
The utility model relates to explosive motor, regulates thermoregulator for the explosive motor water cooling system more specifically.
Background technique
At present, common waxtype thermostat is passive type work, promptly when engine temperature raise, temperature-sensitive wax expanded, the compression sebific duct, and then promotion pushrod movement, under push rod drove, valve was opened gradually, opened major cycle, make motor major cycle circuit cools water flow to radiator, motor begins heat radiation.When engine temperature continued to raise, valve was also along with constantly opening, and the flow of the radiator of flowing through (major cycle) cooling water also constantly increases, and the degree of heat radiation of motor is also constantly strengthened.Decline along with engine temperature, the inductor assembly begins to fall after rise under the effect of main spring, valve begins to close, the flow of major cycle cooling water is also along with minimizing, the engine temperature rate of descent is slack-off, when engine temperature continued to reduce, the inductor push rod continued to fall after rise, closes fully until valve.
But common waxtype thermostat can only be passive this signal of reception engine water temperature, can not take all factors into consideration integrated informations such as intake temperature, outdoor temperature, engine speed; And, discharging, requirements of saving energy are also improved constantly, thereby common waxtype thermostat just can not satisfy the demands along with the development of automotive engineering.
Summary of the invention
The purpose of this utility model is in order to reduce oil consumption, reduces the discharging of CO and HC mixture, reduces soot emissions, and develop aly can initiatively carry out a kind of electronic thermostat of work according to the ECU signal.
The technological scheme that its technical problem that solves the utility model adopts is a kind of electronic thermostat, constitute by inductor assembly, valve, cavity assembly, socket assembly, the inductor assembly comprises push rod, gland, seal ring, sebific duct, body, wax-wrapped pill, it is characterized in that also being equipped with in the inductor assembly electrical heating elements assembly.
Described electrical heating elements assembly is in the afterbody of inductor assembly, comprise electrical heating elements, lead, caudal peduncle, electrical heating elements is in the wax-wrapped pill chamber, and caudal peduncle is exposed to the outside of body, the lead of electrical heating elements is drawn from caudal peduncle, and caudal peduncle, lead, electrical heating elements injection moulding are connected as a single entity; In the junction of electrical heating elements assembly and body, also has seal washer.
Described seal washer is a graphite gasket.
After described lead is drawn from caudal peduncle, pass to annotate and be the lead cavity of one, link to each other with inserted sheet on the socket assembly that is connected the cavity outside with cavity; Between caudal peduncle and lead cavity by seal with elastometic washer.
The electrical heating elements assembly of implanting in advance in inductor assembly inside can generate heat according to the signal that ECU provides, and melts temperature-sensitive wax, and the inductor assembly is initiatively worked.
The beneficial effects of the utility model are:
1, use this product of the present utility model can reduce oil consumption 2%～3%;
2, can reduce CO and HC discharging: 5-15%; The discharging of oxynitrides is controlled; Reduce soot emissions 20%～30%.
Description of drawings
Fig. 1 is the utility model general structure generalized section.
Fig. 2 is the cross-sectional view of inductor assembly in the utility model.
Fig. 3 is the cross-sectional view of inductor assembly in the present common waxtype thermostat.
Among the figure, 1. push rod, 2. gland, 3. seal ring, 4. sebific duct, 5. body, 6. wax-wrapped pill, 7. electrical heating elements, 8. seal washer, 9. caudal peduncle, 10. lead, 11. socket assemblies, 12. cavity assemblies, 13. valves, 14. inductor assemblies.
Embodiment
As shown in Figure 1, 2, electrical heating elements 7, lead 10, caudal peduncle 9 are injection-moulded in together, constitute the electrical heating elements assembly, then, the electrical heating elements assembly is embedded in the body 5, and use graphite grazing packing ring 8 to seal in the junction of electrical heating elements assembly and body 5, guarantee product hermeticity.Then wax-wrapped pill 6, sebific duct 4, seal ring 3, gland 2, push rod 1 are assembled in the body 5 successively,, each component are fixed together by riveting process.From the caudal peduncle of inductor assembly 14 bottoms, draw lead 10, pass to annotate and be the lead cavity of one, link to each other with inserted sheet on the socket assembly 11 that is connected cavity assembly 12 outsides with cavity; By rubber gasket 8 sealings, the socket assembly is connected with the automobile ECU interface between caudal peduncle 9 and lead cavity.ECU is according to engine coolant temperature, load condition, rotating speed, situations such as external temperature are sent heating or halt instruction, electronic thermostat selects suitable temperature control curve to carry out work, by the work of electrical heating elements assembly after receiving instruction, temperature-sensitive wax is melted, compress sebific duct, and promote push rod generation action, thereby control the thermoregulator valve open and close, adjust the operating temperature of motor, make it to reach optimum Working.
