Description

Technical Field

[0001] The utility model belongs to the technical field of engine thermal management and relates to a constant temperature control valve of an engine. Background Art

[0002] The normal operating temperature of the engine is 80℃-90℃. The car is equipped with an engine thermal management module to control the flow of coolant. When the engine temperature is high, it can cool the engine and keep the engine working at a suitable temperature, that is, the engine works at a constant temperature of 80℃-90℃. Therefore, the engine thermal management module is also called the engine's thermostatic control valve, and the thermostatic control valve is equipped with an electronically controlled actuator.

[0003] A Chinese patent document discloses a flow control valve and a cooling system [publication number: CN111692381A]. The flow control valve includes a housing, a driving mechanism (i.e., an actuator) and a valve body (i.e., a valve core). The housing has a valve body receiving portion for receiving the valve body therein. When the valve body is received in the valve body receiving portion, the bottom of the housing is opposite to the bottom of the valve body. The housing is provided with a first connecting port for connecting the valve body receiving portion with the outside and a second connecting port on a surface different from the first connecting port. By rotating the valve body, the connection state between the first connecting port and the second connecting port is changed, thereby adjusting the flow rate. The driving mechanism is located at the negative end of the x-axis of the housing, and the positive end of the x-axis of the housing has a mounting seat, and the mounting seat has three mounting holes for inserting bolts when the flow control valve is fixed to the engine by bolts.

[0004] The above-mentioned flow control valve is the engine's thermostatic control valve, which is generally fixed on the engine. Since the engine generates heat when it is working and the temperature is between 80°C and 90°C (which is relatively high for a thermostatic control valve), the thermostatic control valve is easily heated up and affects the stability of the thermostatic control valve. Utility Model Content

[0005] The utility model aims to solve the above problems in the prior art and proposes a thermostatic control valve for an engine, which solves the technical problem that the existing thermostatic control valve is easily heated up when fixed on the engine and affects the working stability.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] The constant temperature control valve of an engine includes a valve body and an actuator, wherein the actuator is fixed on the top end of the valve body, and the bottom end of the valve body has a fixed seat. The valve body is characterized in that a plurality of grooves are arranged on the bottom surface of the fixed seat, and a parallel plate portion arranged parallel to the top surface of the fixed seat is provided on the outer surface of the valve body and located above the fixed seat, and a plurality of heat dissipation plates arranged in sequence outside the valve body are connected between the parallel plate portion and the top surface of the fixed seat.

[0008] When the thermostatic control valve is fixed on the engine, the bottom surface of the fixing seat is abutted against and fixedly connected to the engine housing. The grooves arranged on the bottom surface of the fixing seat can reduce the contact area between the bottom surface of the fixing seat and the engine, thereby reducing the conduction of heat. The parallel plate portion and the heat sink can not only increase the structural strength of the fixing seat and stabilize the structure of the fixing seat, but also increase the heat dissipation area and accelerate the heat dissipation at the fixing seat of the valve body. In this way, the heat conducted from the engine to the valve body is reduced, and at the same time, the heat conducted from the bottom end of the valve body to the top end of the valve body is also reduced, thereby alleviating the heat rise of the thermostatic control valve and improving the working stability of the thermostatic control valve.

[0009] In the above-mentioned thermostatic control valve of the engine, the heat sink is also connected to the outer side of the valve body. This can enhance the heat dissipation effect of the heat sink, help alleviate the temperature rise of the thermostatic control valve, and improve the working stability of the thermostatic control valve. In addition, this arrangement can further improve the structural strength of the bottom end of the valve body, so that the valve body is fixed and stable on the engine.

[0010] In the above-mentioned thermostatic control valve of the engine, a plurality of heat dissipation radiators are connected between the outer side surface of the valve body and the top surface of the parallel plate portion and are arranged in sequence around the valve body. The provision of the heat dissipation radiators can increase the structural strength of the parallel plate portion and stabilize the structure of the parallel plate portion on the one hand, and increase the heat dissipation area of ​​the outer side surface of the valve body on the other hand, further alleviate the heat rise of the thermostatic control valve and improve the working stability of the thermostatic control valve.

[0011] In the above-mentioned thermostatic control valve for the engine, a plurality of connecting parts are arranged at the edge of the fixing seat, each of which is provided with a bolt hole, and the top end of each connecting part is connected to the parallel plate part. Bolts are inserted into the bolt holes and are threadedly connected to the engine, thereby fixing the thermostatic control valve on the engine. The connection between the connecting part and the parallel plate part stabilizes the structure at the bottom end of the valve body, thereby making the thermostatic control valve fixed stably on the engine.

[0012] In the above-mentioned thermostatic control valve of the engine, the top surface of the valve body has several protruding connecting columns, and the actuator has connecting lugs corresponding to the connecting columns one by one. The connecting lugs abut against the top surface of the corresponding connecting column and are fixed, and there is a gap between the bottom surface of the actuator and the top surface of the valve body. The actuator is fixed to the valve body through the connecting lugs and the connecting columns, and there is a gap between the bottom surface of the actuator and the top surface of the valve body, which can reduce the contact area between the actuator and the valve body, thereby reducing the conduction of heat. At the same time, the existence of the gap is also conducive to the circulation of air and accelerates the heat dissipation. In this way, the heat conducted from the valve body to the actuator is reduced, and the heat dissipation at the top of the valve body is accelerated, which can alleviate the influence of the thermostatic control valve being heated up on the actuator, and is conducive to improving the working stability of the thermostatic control valve.

[0013] In the above-mentioned thermostatic control valve of the engine, the top surface of the valve body is also provided with a protruding convex strip, and the convex strips are in number and arranged in sequence along the circumference of the valve body, and the bottom surface of the actuator is against the top surface of the convex strip. The convex strip has an upward supporting effect on the actuator, so that the actuator is fixed and stable on the valve body. At the same time, the setting of the convex strip can also ensure that there is a gap between the top surface of the valve body and the bottom surface of the actuator, so that the top of the valve body can easily dissipate heat. In addition, the convex strips are arranged separately, which is conducive to the circulation of air and heat dissipation. Therefore, the setting of the convex strip is conducive to improving the working stability of the thermostatic control valve.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] A parallel plate portion is arranged on the outer surface of the bottom end of the valve body above the fixed seat, a plurality of heat sinks are arranged between the parallel plate portion and the fixed seat, and a plurality of grooves are arranged on the bottom surface of the fixed seat, which is conducive to relieving the temperature rise of the thermostatic control valve and improving the working stability of the thermostatic control valve. There is a gap between the bottom surface of the actuator and the top surface of the valve body, which is conducive to heat dissipation and heat insulation, and can alleviate the influence of the temperature rise of the thermostatic control valve on the actuator.

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figure 1As shown, a thermostatic control valve for an engine includes a valve body 1, a valve core installed in the valve body 1, and an actuator 2 for controlling the rotation of the valve core, and the actuator 2 is fixed on the top of the valve body 1. The edge of the top surface of the valve body 1 is provided with a plurality of protruding connecting columns 1e, and the outer surface of the actuator 2 is provided with connecting lugs 2a corresponding to the connecting columns 1e one by one. The bottom of the actuator 2 is located between these connecting columns 1e, and the connecting lugs 2a are abutted against and fixed on the top surfaces of the corresponding connecting columns 1e, and the connecting lugs 2a are fixed to the connecting columns 1e by screws. In this embodiment, three connecting columns 1e and three connecting lugs 2a are provided, and the number may also be appropriately increased or decreased, such as two or four. In combination Figure 2 As shown, there is a gap 3 between the bottom surface of the actuator 2 and the top surface of the valve body 1. Figure 3 As shown, the top surface of the valve body 1 also has a protruding arc-shaped convex strip 1f, there are several convex strips 1f and they are arranged in sequence along the circumference of the valve body 1, all the convex strips 1f are arranged on the same circumference, and the bottom surface of the actuator 2 is in contact with the top surface of the convex strip 1f. In this embodiment, there are three convex strips 1f, and the number can also be appropriately increased or decreased, such as two or four.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, the bottom end of the valve body 1 has a fixing seat 1a. The fixing seat 1a is roughly triangular in shape, and connecting parts 1g are provided on the three corners of the fixing seat 1a, and each connecting part 1g is provided with a bolt hole 1g1. In the present embodiment, three connecting parts 1g are provided, and the number can also be appropriately increased or decreased, such as two or four. Several grooves 1a1 are provided on the bottom surface of the fixing seat 1a, and the bottom surface of the fixing seat 1a also has two protruding positioning columns. When the thermostatic control valve is fixed to the engine housing, the bottom surface of the fixing seat 1a is against the engine housing, the positioning column is inserted into the engine housing, and bolts threadedly connected to the engine housing are passed through the bolt holes 1g1, and the valve body 1 is fixed to the engine housing by the bolts. The outer side surface of the valve body 1 is provided with a parallel plate portion 1b arranged parallel to the top surface of the fixed seat 1a above the fixed seat 1a, the top end of the connecting portion 1g is connected to the parallel plate portion 1b, and a plurality of heat dissipation plates 1c arranged in sequence on the outer periphery of the valve body 1 are connected between the parallel plate portion 1b and the top surface of the fixed seat 1a. The heat dissipation plate 1c is also connected to the outer side surface of the valve body 1. A plurality of heat dissipation radial plates 1d arranged in sequence on the outer periphery of the valve body 1 are connected between the outer side surface of the valve body 1 and the top surface of the parallel plate portion 1b.

[0024] The groove 1a1 provided on the bottom surface of the fixing seat 1a can reduce the contact area between the bottom surface of the fixing seat 1a and the engine, thereby reducing the conduction of heat. The parallel plate portion 1b and the heat dissipation plate 1c can not only increase the structural strength of the fixing seat 1a and stabilize the structure of the fixing seat 1a, but also increase the heat dissipation area, thereby accelerating the heat dissipation at the fixing seat 1a of the valve body 1. The actuator 2 is fixed to the valve body 1 through the connecting lug 2a and the connecting column 1e, and there is a gap 3 between the bottom surface of the actuator 2 and the top surface of the valve body 1, which can reduce the contact area between the actuator 2 and the valve body 1, thereby reducing the conduction of heat. At the same time, the existence of the gap is also conducive to the circulation of air and accelerates the heat dissipation. In this way, the heat conducted from the engine to the valve body 1 is reduced, and the heat conducted from the bottom end of the valve body 1 to the top end of the valve body 1 is reduced, and the heat conducted from the valve body 1 to the actuator 2 is also reduced, thereby alleviating the heat rise of the thermostatic control valve and improving the working stability of the thermostatic control valve.
