Under the low-temperature environment, the viscosity of the petrochemical fuel is increased in the low-temperature environment, so that atomization and combustion are not facilitated, the flowability of lubricating oil is deteriorated, the resistance of each moving part is increased, and the engine is difficult to start. In order to make the engine easier to start in a low temperature environment, an intake air preheating device may be provided to preheat the air that enters the engine.

At present, the air inlet preheating device preheats air by heating air through the electric heating plate, and the air is in direct contact with the electric heating plate to easily cause larger wind resistance, so that the air inlet efficiency of the air inlet preheating device is low.

In this application, through set up the guide surface of being connected with the windward side on the piece that generates heat to make the guide surface protruding in the piece setting that generates heat, make the air current and the side that the guide surface contacted the back accessible guide surface flow to the piece that generates heat, can reduce the area of windward side like this, reduce the windage that air current and windward side direct contact produced, the guide surface can accelerate the region that the guide gas flow direction generated between the piece that generates heat and the gas passage inner wall, make the gas pass through gas passage more fast, thereby can reduce the windage of the heating element of this application.

The heating assembly and the engine provided by the application are described in detail below with reference to specific embodiments.

The embodiment of the application provides an engine, which comprises an engine main body and a heating assembly. The heating component can be arranged at the air inlet of the engine, so that combustion-supporting gas entering the engine can be heated by the heating component, and the engine is easier to start in a low-temperature environment. In particular, combustion air may be in contact with the heating elements of the heating assembly as it passes through the heating assembly so that the combustion air may be heated. However, in the heating assembly of the present engine, the combustion-supporting gas is more windage to contact with the heating member when passing through the heating assembly, so that the efficiency of passing the combustion-supporting gas through the heating assembly is lower.

Therefore, in order to solve the technical problem that the wind resistance of the heating assembly of the current engine to the combustion-supporting gas is large, the embodiment of the application also provides a heating assembly, and the heating assembly can be applied to the engine of the application.

Referring to fig. 1, the heating assembly includes a base 100 and a heat generating member 200, wherein the base 100 is a base member of the heating assembly of the present application, and the base 100 may provide a mounting base for at least some other components of the heating assembly. The base 100 is provided with a gas channel 110 therein, and the base 100 has an air inlet and an air outlet in communication with the gas channel 110, and air can enter the gas channel 110 through the air inlet and be discharged through the air outlet. Specifically, the base 100 may be configured as a frame structure or a barrel structure, and when the base 100 is a frame structure, the structure of the base 100 is compact. The base 100 may be made of a high temperature resistant metal material, so that the base 100 has a better structural strength, and in particular, the base 100 may be made of a copper material.

At least a portion of the heat generating member 200 is disposed in the gas passage 110 of the base 100, and the heat generating member 200 has a gap with the bottom wall of the base 100 such that gas can pass through the gas passage 110 of the base 100 from the gap space between the inner wall of the gas passage 110 and the heat generating member 200, so that air passing through the gas passage 110 of the base 100 can contact the heat generating member 200, and thus the air can be heated. Specifically, referring to fig. 2, the heat generating member 200 further has a side 220, the side 220 being located at a side of the heat generating member 200, and the side 220 of the heat generating member 200 being opposite to an inner wall of the gas passage 110, so that air may pass through the gas passage 110 of the base 100 from a space between a side wall of the heat generating member 200 and the inner wall of the base 100. The heat generating member 200 generates heat to raise the temperature in the gas passage 110 of the base 100, so that air can be heat-exchanged with the hot air of the gas passage 110 after entering the gas passage 110, and thus the air can be heated.

Specifically, the heat generating element 200 may be disposed entirely inside the gas channel 110 of the base 100, or a portion of the heat generating element 200 is disposed inside the gas channel 110, and another portion of the heat generating element 200 is disposed outside the gas channel 110. When the heat generating member 200 is completely disposed in the gas passage 110, the heating effect of the air passing through the gas passage 110 is better.

Referring to fig. 2, the heat generating element 200 further has a windward side 210, the sides 220 of the heat generating element 200 are located at two sides of the windward side 210, and the windward side 210 of the heat generating element 200 is opposite to the flow direction of air entering the air channel 110 from the air inlet, so that the air contacts the windward side 210 of the heat generating element 200 when contacting the heat generating element 200. Specifically, the windward side 210 of the heat generating element 200 is perpendicular to the flow direction of the air entering the air channel 110 from the air inlet, so that the windward side 210 has a blocking effect on the air, and the air flows to both sides of the windward side 210 after contacting with the windward side 210, so as to flow to the area between the heat generating element 200 and the inner wall of the base 100, and passes through the air channel 110 from the area. Therefore, the windward side 210 causes a certain wind resistance to the flowing air, and the larger the area of the windward side 210 of the heat generating member 200 is, the larger the wind resistance to the air is.

Referring to fig. 2, the heat generating member 200 further has a guide surface 230, both sides of the guide surface 230 are connected to the windward side 210 and the side 220, respectively, and the guide surface 230 intersects both the windward side 210 and the side 220, so that the guide surface 230 is disposed obliquely with respect to the windward side 210. The guide surface 230 is also opposite to the flow direction of the air from the air inlet into the gas passage 110 so that the air flowing in the gas passage 110 can contact the guide surface 230 and the windward side 210. The windward side 210 is further protruded from the heat generating component 200, so that when air flows to both sides of the windward side 210 after contacting the windward side 210, the air can flow onto the guiding surface 230, and the guiding surface 230 can guide the air to flow to the space between the heat generating component 200 and the inner wall of the gas channel 110. When a portion of the air directly contacts the guide surface 230, which is disposed obliquely with respect to the windward side 210, may also guide the portion of the air to rapidly flow toward the space between the heat generating member 200 and the inner wall of the gas channel 110.

Specifically, the guiding surface 230 is disposed at an angle with respect to the flow direction of the air entering the gas channel 110 from the air inlet, and the angle is smaller than 90 degrees, so that the guiding surface 230 can be disposed obliquely with respect to the flow direction of the air entering the gas channel 110 from the air inlet, which reduces the wind resistance when the guiding surface 230 contacts with the air, and allows the air to pass through the guiding surface 230 efficiently. In addition, the area of the surface of the heat generating member 200 perpendicular to the air flow direction can be reduced by providing the guide surface 230, so that the wind resistance of the heating assembly of the present application can be effectively reduced.

In the heating component provided in this embodiment, the guiding surface 230 connected with the windward surface 210 is disposed on the heating component 200, and the guiding surface 230 is protruded on the heating component 200, so that the airflow can flow to the side surface 220 of the heating component 200 through the guiding surface 230 after contacting with the guiding surface 230, thus the area of the windward surface 210 can be reduced, the wind resistance generated by the direct contact of the airflow and the windward surface 210 can be reduced, the guiding surface 230 can accelerate and guide the airflow to the area between the heating component 200 and the inner wall of the gas channel 110, and the gas can more quickly pass through the gas channel 110, thereby reducing the wind resistance of the heating component of this application.

In some embodiments, the guiding surface 230 of the heat generating component 200 may be specifically configured as a slope, an arc surface, or a combination of a slope and an arc surface. Referring to fig. 2, when the guiding surface 230 is an inclined surface, an included angle between the guiding surface 230 and the air flowing in the air channel 110 of the base 100 may be relatively smaller, so that the guiding surface 230 extends in a direction relatively closer to the air flowing in the air channel 110, so that the resistance of the guiding surface 230 to the air is smaller, and the wind resistance of the heating assembly of the present application is smaller. In addition, the guiding surface 230 may be provided as a plurality of inclined surfaces, the plurality of inclined surfaces are sequentially connected, and the included angle between the adjacent inclined surfaces is smaller than 90 degrees, and each of the plurality of inclined surfaces can serve the purpose of guiding air so that the air passes through the air channel 110 efficiently. In addition, the greater the number of slopes in the multi-stage slope, the smoother the transition of the guide surface 230 may be, so that the wind resistance of the guide surface 230 may be further reduced, and the gas may efficiently flow through the guide surface 230 to the region between the heat generating member 200 and the inner wall of the susceptor.

Referring to fig. 3, when the guide surface 230 is a curved surface, the guide surface 230 has a streamline structure such that the transition between the regions of the guide surface 230 is natural, so that the curved surface of the guide surface 230 can sufficiently guide the air flowing from the side of the guide surface 230 adjacent to the windward side 210 to the side of the guide surface 230 adjacent to the side 220 when the air flows through the surface of the guide surface 230. Of course, it should be understood that when the guiding surface 230 is an arc surface, the guiding surface 230 may also have a multi-segment arc surface structure, specifically, at least some of the segments of arc surfaces have different circle centers, so that the guiding surface 230 may also serve the purpose of guiding air.

In some embodiments, referring to fig. 3, the guiding surface 230 of the heat generating element 200 may specifically be an arc surface, and the guiding surface 230 is an arc surface protruding away from the heat generating element 200. The transition of the guide surface 230 in the cambered surface configuration in the direction from one end to the other end thereof is more natural. When the flowing air contacts the guide surface 230, the air may be more smoothly flowing against the guide surface 230. When the guiding surface 230 of the heating element 200 is in a cambered surface structure, the guiding surface 230 may be arranged to protrude in a direction away from the heating element 200, so that the guiding surface 230 presents a convex structure on the outer wall of the heating element 200, when flowing air contacts with the guiding surface 230, the contact position of the flowing air and the guiding surface 230 is more likely to be in a nearly tangential state with the guiding surface 230, thus the flowing air can be prevented from directly flowing towards the guiding surface 230, and the windage applied when the air flows along the surface of the guiding surface 230 can be further reduced, so that the air can more quickly pass through the guiding surface 230.

In some embodiments, referring to fig. 4, when the guiding surface 230 of the heat generating element 200 of the present application is a multi-segment inclined surface, a rounded corner structure may be disposed between adjacent connected inclined surfaces, so that the connection portion of the adjacent inclined surfaces is an arc surface, thereby making the transition of the connection portion of the adjacent inclined surfaces more natural. When air flows between adjacent two inclined surfaces, the cambered surface structure between the adjacent inclined surfaces can guide the air to rapidly pass through the area between the adjacent inclined surfaces. When the guiding surface 230 of the heating element 200 of the present application is a structure combining an inclined surface and an arc surface, one end of the arc surface may be connected with the windward side 210, the other end of the arc surface may be connected with the inclined surface, and one end of the inclined surface facing away from the arc surface may be connected with the side surface 220. It should be appreciated that when the pitch of the opposite ends of the inclined surface and the pitch of the opposite ends of the arc surface are the same, the path length of the inclined surface is shorter than the path length of the arc surface, so that the air passing through the windward side 210 may first contact the arc surface to guide the air to flow to both sides of the heat generating member 200 quickly, and then the air flows along the inclined surface so that the air may pass through the inclined surface more quickly, and furthermore, the inclined surface has a certain guiding effect on the air so that the air may pass through the guiding surface 230 more quickly.

In some embodiments, referring to fig. 5, the heat generating component 200 of the present application includes a plurality of first segments 240 and a plurality of second segments 250, the plurality of first segments 240 and the plurality of second segments 250 are alternately connected end to end in sequence, and adjacent first segments 240 and second segments 250 are disposed at an included angle, so that the length of the heat generating component 200 may be set longer in the case that the heat generating component 200 is disposed in the gas channel 110 of the base 100. It should be appreciated that both the first and second sections 240 and 250 of the heat generating member 200 may generate heat to heat air, and thus the air flowing in the gas passage 110 of the base 100 may contact with the first and second sections 240 and 250, thereby making the heat generating member 200 more effective for heating the air passing through the gas passage 110.

The base 100 of the present application may be configured as a rectangular-like frame structure, so that the inner walls in the gas channel 110 of the base 100 are opposite to each other, specifically, referring to fig. 1, the inner walls of the base 100 may include a first inner wall 111 and a second inner wall 112 opposite to each other, and a third inner wall 113 and a fourth inner wall 114 opposite to each other, where the first inner wall 111 is connected to the third inner wall 113, and the first inner wall 111 is further connected to the fourth inner wall 114, the second inner wall 112 is connected to the third inner wall 113, and the second inner wall 112 is further connected to the fourth inner wall 114. The adjacent first and second sections 240 and 250 may be disposed perpendicular to each other, such that the first section 240 may be opposite and parallel to the first and second inner walls 111 and 112, and the second section 250 may be opposite and parallel to the third and fourth inner walls 113 and 114, thereby making the structure of the heat generating component 200 more regular.

It should be appreciated that the first and second sections 240, 250 each have a windward side 210, a side 220, and a guide surface 230, and that the windward side 210, side 220, and guide surface 230 of the first section 240 may be similar in construction to the windward side 210, side 220, and guide surface 230 of the second section 250 in principle and may be sized differently, so that air may efficiently pass through the gas channel 110 of the base 100 after contacting the first and second sections 240, 250 such that air adjacent to both the first and second sections 240, 250 may be sufficiently heated.

In some embodiments, the plurality of first sections 240 of the heat generating member 200 may be spaced apart in a direction from the first inner wall 111 to the second inner wall 112 of the gas channel 110 of the base 100, and a single first section 240 may be disposed in a direction from the third inner wall 113 to the fourth inner wall 114, with both ends of the single first section 240 being adjacent to the third inner wall 113 and the fourth inner wall 114, respectively. The plurality of second segments 250 may be disposed between the plurality of adjacent first segments 240, respectively, such that the plurality of second segments 250 may be opposite the third inner wall 113 and the fourth inner wall 114 of the base. The plurality of first segments 240 are distributed along the first inner wall 111 to the second inner wall 112 such that the plurality of first segments 240 are distributed at different locations within the gas channel 110 such that air passing through different areas within the gas channel 110 may be substantially heated by adjacent first segments 240. Since the first and second sections 240, 250 are alternately connected end to end, a portion of the second section 250 may be disposed adjacent the third inner wall 113 and another portion of the second section 250 may be disposed adjacent the fourth inner wall 114. This may allow the second segments 250 to be distributed over different areas within the gas channel 110 of the base 100 such that air passing through different areas within the gas channel 110 may be substantially heated by adjacent second segments 250.

The second sections 250 of the heat generating component 200 of the present application may be connected to opposite and adjacent inner walls, specifically, a portion of the second sections 250 adjacent to the third inner wall 113 may be connected to the third inner wall 113, and a portion of the second sections 250 adjacent to the fourth inner wall 114 may be connected to the fourth inner wall 114, so that the heat generating component 200 and the base 100 have multiple connection portions, and the connection between the heat generating component 200 and the base 100 is stable and reliable.

In some embodiments, the heating assembly of the present application further includes a heat insulator 300, and the heat generating member 200 may be connected to the base 100 through the heat insulator 300. The heat insulating member 300 may be fixed to the base 100, and the heat generating member 200 is connected to the heat insulating member 300, so that the heat insulating member 300 is located between the heat generating member 200 and the base 100, and the heat insulating member 300 may prevent the heat generating member 200 from directly contacting the base 100, thereby preventing the heat generated by the heat generating member 200 from being directly transferred to the base 100 and causing the temperature of the base 100 to be too high, so as to protect the base 100. The number of the heat insulating members 300 may be two, two heat insulating members 300 may be disposed on the third inner wall 113 and the fourth inner wall 114 of the gas channel 110 of the base 100, and the plurality of second sections 250 may be connected to the base 100 through the heat insulating members 300, respectively, so that the heat generating member 200 may avoid the over-high temperature of the base 100 under the condition of reliable fixed connection with the base 100.

Referring to fig. 6, the heat generating member 200 may be connected to the base 100 through the heat insulating member 300 by means of a rivet connection, specifically, the heat generating member 200, the heat insulating member 300, and the third and fourth inner walls 113 and 114 of the base 100 may be provided with corresponding rivet holes, and both the heat generating member 200 and the heat insulating member 300 may be fixed to the base 100 through rivets 500, so that it may not be necessary to separately fix the heat generating member 200 to the heat insulating member 300 or to separately fix the heat insulating member 300 to the base 100. Of course, in other embodiments, the heat generating element 200, the heat insulating element 300, and the third inner wall 113 and the fourth inner wall 114 of the base 100 may be provided with corresponding screw holes, and the heat generating element 200 and the heat insulating element 300 may be fixed to the base 100 by screws. In this way, the connection structure of the heat generating element 200, the heat insulating element 300 and the base 100 is compact, the cross-sectional area of the gas channel 110 of the base 100 in the air flow direction can be set larger, and correspondingly, the heat generating element 200 can be set larger, so that the air flow rate passing through the gas channel 110 is larger, and the air heating effect is better. The insulator 300 may be formed of a mica sheet, which may allow the insulator 300 to be relatively thinner, thereby further compacting the structure of the insulator 300.

Of course, referring to fig. 7, the base 100 of the present application may further provide a receiving groove 120, where the groove shape of the receiving groove 120 is matched with the shape of the heat insulation member 300, so that the heat insulation member 300 may be embedded in the receiving groove 120, so that the heat insulation member 300 may be fixed on the base 100.
