Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle heating, in particular to a heat conversion system for a diesel vehicle. Background Art

[0002] The performance of vehicles in extreme cold weather in winter is a major challenge, especially for diesel vehicles, whose thermal operation paths are different in winter and summer. Therefore, how to properly start and run diesel engines in extreme cold weather year-round is an urgent problem that needs to be solved.

[0003] The conversion valve is an HTH type valve used for the conversion of the small circulation water circuit of automobile engines. It is widely used in various automobile engines, especially in diesel vehicles, where the application of conversion valves is particularly common.

[0004] Generally, diesel vehicles transporting between the north and the south use a combination of low-grade and high-grade oils, or the high-grade oil is not high enough. When the car is driving at high speed, the wear and tear of the matching heated fuel tank is far lower than the daily temperature, causing wax and frost to form on the oil cup of the matching heated fuel tank.

[0005] The main principle of the matching heated fuel tank heating is to introduce the engine coolant into the matching heated fuel tank through a pipe, heat the diesel in the matching heated fuel tank, and make it reach a certain temperature in a very low temperature environment so that it no longer condenses and can be used normally by the engine.

[0006] Special back-pressure radiators are heating devices primarily used for heating. They are primarily used in northern regions with cold winters to provide warmth. Previously, cast iron special back-pressure radiators were mostly used, but now more materials have been developed. Cast iron special back-pressure radiators have gradually withdrawn from the market. New types of special back-pressure radiators, such as steel special back-pressure radiators, steel plate special back-pressure radiators, copper-aluminum composite radiators, and aluminum special back-pressure radiators, are superior to cast iron radiators in terms of both material and manufacturing process, and have become the most mainstream special back-pressure radiators on the market. In cold regions such as the Northeast, heaters have replaced fire walls and kangs as people's new heating equipment.

[0007] The application of conversion valves in existing vehicles is relatively scattered. In the operation of traditional vehicle water channels, the head of traditional automobile water pumps decreases with idling / low speed as the power decreases, which leads to unstable heating of the small water tank in the car cab in winter, making it difficult to meet people's winter car use. Due to the redni phenomenon, existing cars cannot effectively solve problems such as water resistance, differential pressure resistance, etc., causing people to fall into distress when installing the water outlet of the automobile heating boiler heater body: when the car is idling or installing the automobile heating boiler heater body, the automobile heating boiler water pump may lack water and burn out, resulting in unsatisfactory engine preheating, the small water tank is not hot, and the air heater cannot preheat the car after installation.

[0008] In summary, at present, multiple problems such as supporting the heating of a heating-type fuel tank, winter heating, summer operation, and parking are problems that diesel vehicles urgently need to solve. However, existing diesel vehicles mostly solve the problems of single functions through separate modifications. Therefore, there is an urgent need for a heat conversion system for diesel vehicles with more powerful functions. Summary of the Invention

[0057] The following further illustrates the specific implementation of the heat conversion system for diesel vehicles of the present invention in conjunction with the embodiments. The heat conversion system for diesel vehicles of the present invention is not limited to the description of the following embodiments.

[0058] Example:

[0059] A diesel vehicle heat conversion system, such as Figure 1-11As shown in the figure, it includes an HTH type heat conversion valve 0, an automotive heating boiler 1, a supporting heating type fuel tank 2, a special backpressure type radiator 3, the engine small cycle outlet and return water 4, and the cab small water tank 5. The automotive heating boiler 1, the supporting heating type fuel tank 2, the special backpressure type radiator 3, the engine small cycle outlet and return water 4, and the cab small water tank 5 are all connected to the HTH type heat conversion valve 0.

[0060] In a possible implementation manner, on one side of the HTH type heat conversion valve 0, from left to right in sequence, there are an engine small cycle return water cold water port 01, a connecting cab small water tank outlet interface 02, a No. 0 supporting heating type fuel tank heater outlet water port 03, a backpressure special backpressure type radiator upper port 04, a cab small water tank inlet port 05, and a backpressure special backpressure type radiator lower port 06. On the other side directly below the HTH type heat conversion valve 0, from left to right in sequence, there are a No. 0 supporting heating type fuel tank heater inlet water port 011, an automotive heating boiler heater outlet water port 041, an automotive heating boiler water pump inlet port 061, and an engine small cycle outlet hot water port 07. At the intersection of the cab small water tank outlet interface 02 and the engine small cycle outlet hot water port 07, there is a ball valve a. At the connection between the No. 0 supporting heating type fuel tank heater outlet water port 03 and the HTH type heat conversion valve 0, there is a ball valve b. At the intersection of the backpressure special backpressure type radiator upper port 04 and the backpressure special backpressure type radiator lower port 06, there is a ball valve c.

[0061] In a possible implementation manner, the left and right ends of the HTH type heat conversion valve 0 are respectively the engine small cycle return water cold water port 01 and the cab small water tank inlet port 05.

[0062] In a possible implementation manner, there are two channels in the ball valve a. Among them, the channel a1 is used to connect the engine small cycle outlet hot water port 07 and the HTH type heat conversion valve 0, and the channel a2 is used to connect the cab small water tank outlet interface 02, the engine small cycle return water cold water interface, and the No. 0 supporting heating type fuel tank heater inlet water port 011;

[0063] There is a T-shaped channel in the ball valve b. Among them, the channel b1 is used to connect the No. 0 supporting heating type fuel tank heater outlet water port 03, and the channel b2 is used to connect the channel b1, connect the ball valve a and the ball valve c;

[0064] There are two channels in the ball valve c. Among them, the channel c1 is used to connect the ball valve b, the backpressure special backpressure type radiator lower port 06, and the automotive heating boiler water pump inlet port 061, and the channel c2 is used to connect the cab small water tank inlet port 05, the backpressure special backpressure type radiator upper outlet interface, and the automotive heating boiler heater outlet water port 041;

[0065] A car heating boiler heater outlet 041 is provided at the lower bend of the tee on the upper side of the back pressure type radiator, which is connected to the water outlet of the car heating boiler 1. The water inlet of the car heating boiler 1 is connected to the water outlet of the fast and slow water pump 08, and the water inlet of the fast and slow water pump 08 is connected to the water pump inlet 061.

[0066] In one possible embodiment, a tee is provided downward at the lower bend of the tee to connect the water inlet 011 of the matching heating type tank heater, the water outlet 041 of the automobile heating boiler heater, and the water inlet and outlet of the automobile heating boiler water pump 061. This tee is drilled downward through the plate to connect the external L-shaped pipe for docking with the tee in the cab.

[0067] In one possible embodiment, the hot water interface 07 of the engine water outlet is in a right-angled L-shaped downward direction in the cab. It is drilled through the plate and passes out of the cab. The outer part is also in a right-angled L-shaped upward direction and is connected by inner and outer threads.

[0068] In a possible embodiment, the water inlet 011 of the No. 0 box heater, the water outlet 041 of the automobile heating boiler heater, the water pump port 061 of the automobile heating boiler and the right-angle lower bend 07 are drilled through the plate at the same time, passed out of the cab, and connected with the inner and outer threads of the L-shaped right-angle pipe mouth outside the cab, and play a fixing role.

[0069] In one possible implementation, Figure 3 As shown, during summer vehicle operation, ball valve a has two channels. Channel a1 connects the engine's small-circuit hot water outlet 07 and the engine's small-circuit cold water return 01, while channel a2 connects the vehicle's small water tank and the T-valve. During this time, channel a2 is inactive in the cab's small water tank, and the water circulating in channel a1 flows directly back into the engine's large-circuit system, eliminating hot air from the cab during summer.

[0070] Working principle:

[0071] like Figure 3 As shown, in summer, the water flow direction is from the hot water interface of the engine small circulation outlet to the a1 channel of the conversion valve 1, connecting 07 to flow to 01 and then directly back to the engine small circulation return water cooling outlet for use.

[0072] The water flow direction is from the engine small circulation water outlet to the HTH valve outlet 07 to 01 to the engine small circulation return water system, and the matching heating type fuel tank heater water outlet connection 03 is in the T-type valve closed state.

[0073] In one possible implementation, Figure 4As shown, during winter vehicle operation, ball valve a is provided with two channels, wherein channel a1 is used to connect the engine small circulation hot water outlet O7 and T-valve b, and channel a2 is used to connect the cab small water tank outlet O2 and the engine small circulation return water cooling outlet No. 0 supporting heating type oil tank heater inlet (01-011). Ball valve b is provided with a T-channel, wherein channel b1 is used to connect the No. 0 supporting heating type oil tank heater outlet (03), and channel b2 is used to connect channel b1 and H valve a and H valve C.

[0074] There are two channels in the ball valve c, among which channel c1 is used to connect the T-valve b and the lower port of the back pressure radiator, the automobile heating boiler water pump 061, and channel c2 is used to connect the upper port of the back radiator, the automobile boiler fire body (04-041) and the water inlet 05 of the small water tank in the cab.

[0075] Working principle: Figure 4As shown, in winter, when it is not started in winter and needs to be started, the work is as follows: the fast and slow water pump 08 adds water to the car heating boiler 1 to the upper port of the north pressure special back pressure radiator and the car heating boiler heater outlet (04-041) → the cab small water tank water inlet interface 05 → the cab small water tank → the cab small water tank outlet 02 → the engine cold water return interface 01 and the No. 0 supporting heating type oil tank heater inlet → the engine small cycle main body engine → the engine small cycle water outlet hot water outlet 07 → T-type valve b1 connected to the No. 0 supporting heating type oil tank heater outlet 03, b2 → C1 → the back pressure special back pressure radiator lower port 06, the car heating boiler water pump inlet 061 → the car heating boiler water pump main body 08, to realize a whole cycle. During low water pressure conditions, due to the high installation position of the back-pressure radiator, the flow from the back-pressure radiator's lower water inlet 06 to the back-pressure radiator's upper water outlet 04 is slow when heating is not enabled. The fuel tank heater's inlet and outlet 03 to the fuel tank heater's outlet 011, when not enabled in winter, sometimes needs to be in a T-shaped closed position before being opened. This is to ensure the engine is preheated first. This ensures that the oil circuits are both connected, and the oil circuits to the engine and fuel tank are both open. The water resistance in the oil circuits is lower than that of the engine, allowing for faster preheating. Once the engine is successfully preheated and the oil is wax-free, open the T-valve at the appropriate time to preheat the fuel tank for three minutes to dewax it, allowing the diesel engine to start normally using 0-grade diesel within a temperature of -60 degrees Celsius. The fuel tank's water resistance is lower than the engine's, which in turn is lower than the resistance of the back-pressure radiator. In winter, after starting the engine, the vehicle heating boiler and the engine can be used simultaneously. Even if the vehicle heating boiler is turned off after the engine is operating normally, the fuel tank heating system can still function normally. When the engine speed reaches 1600 rpm or above, the resistance of the back-pressure radiator is approximately equal. When the engine speed exceeds 1800 rpm, the resistance exceeds the resistance of the back-pressure radiator, allowing the back-pressure radiator to provide normal heating. This achieves the purpose of reducing heating pressure. The hot water port 07 of the engine water outlet is connected to the return water port 01 of the engine cold water outlet.

[0076] In one possible implementation, Figure 5As shown, two channels are provided in the ball valve a, wherein channel a2 is used to connect the water outlet of the automobile small water tank (02) → the small water tank in the cab → the water inlet interface of the automobile small water tank (05) → C1 → the water pump inlet → the automobile heating boiler water pump (08) → the automobile heating boiler body (09) → the water outlet of the automobile heating boiler heater → C2 → b2 → a2 → the water outlet of the automobile small water tank to form a cycle, wherein the automobile heating boiler water pump 08 → the automobile heating boiler body 09 → the automobile heating boiler heater outlet 041 → the upper port 04 of the back pressure special back pressure type radiator → the back pressure body special back pressure type radiator → the lower port 06 of the back pressure body special back pressure type radiator → the automobile heating boiler water inlet 061 → the automobile heating boiler water pump forms an overall cycle.

[0077] A T-shaped channel is provided in the ball valve b, wherein the channel b1 is in a closed state and the channel b2 is used to connect the H valve C and the H valve α.

[0078] There are two channels in the ball valve c, among which channel c1 is used to connect the small car water tank 05 and the water inlet interface 06 below the back pressure type radiator → water pump inlet 061 → car heating boiler water pump body, and channel c2 is used to connect the car heating boiler heater 041, the water outlet interface 04 above the back pressure type radiator and the T-type valve b2 channel.

[0079] Working principle:

[0080] like Figure 5 As shown, when the car stops on the road, the water is fed from the car heating boiler booster pump water inlet interface 061 → car heating boiler heater pump main body interface 08 → car heating boiler main body 09 → car heating boiler booster water outlet 041 interface → back pressure radiator upper water inlet interface 04 and C2 → back pressure radiator main body and cab small water tank → back pressure radiator lower port 06 and (C2→b2→a2→02) car small water tank outlet 02 → back pressure radiator lower port 06 and car small water tank water inlet 05 → water pump water inlet 061, forming an overall cycle.
