Description

Technical Field

[0001] The invention 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 cars in extremely cold weather in winter is a big problem, especially for diesel vehicles, whose winter / summer car heat operation circuits are different. Therefore, how to correctly start and run No. 0 diesel in winter for diesel engines in extremely cold weather all year round is a problem that needs to be solved urgently.

[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 oil, or the high-grade oil is not high enough. When the car is driving at high speed, the wear and tear of the supporting heated fuel tank is far lower than the daily temperature, causing wax and frost on the oil cup of the supporting 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 the pipeline, heat the diesel in the matching heated fuel tank, make it reach a certain temperature in a very low temperature environment, no longer condense, and thus can be used normally by the engine.

[0006] Special back pressure radiator is a heating equipment mainly used for heating. It is mainly used in the cold northern regions in winter and has the function of keeping warm. In the past, cast iron special back pressure radiators were mostly used, and special back pressure radiators of more materials have been developed. Cast iron special back pressure radiators have gradually withdrawn from the market. New 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 materials and manufacturing processes, and have become the most mainstream special back pressure radiators on the market. In cold areas such as the Northeast, heating has replaced fire walls and kangs and become people's new heating equipment.

[0007] The application of conversion valves in existing vehicles is relatively scattered. In the water channel operation of traditional vehicles, 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, which is difficult to meet people's winter car use. Due to the redni phenomenon, existing cars cannot effectively solve problems such as water resistance difference and pressure resistance, causing people to fall into distress when installing the water outlet of the automobile heating boiler heater body: when the car is idling or the automobile heating boiler heater body is installed, 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 heating the supporting 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

[0058] Example:

[0059] A diesel vehicle heat conversion system, such as Figure 1-11As shown, it includes an HTH type converter 0, an automotive heating boiler 1, a supporting heating fuel tank 2, a special back-pressure radiator 3, the engine small cycle outlet and return water 4, and the cab small water tank 5.

[0060] In a possible implementation, on one side of the HTH type heat conversion valve 0, from left to right in sequence, there are provided an engine small cycle return water cold water port 01, a connection cab small water tank outlet interface 02, a No. 0 supporting heating type fuel tank heater outlet port 03, a back-pressure special back-pressure radiator upper port 04, a cab small water tank inlet port 05, and a back-pressure special back-pressure 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 provided a No. 0 supporting heating type fuel tank heater inlet port 011, an automotive heating boiler heater outlet 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 port 03 and the HTH type heat conversion valve 0, there is a ball valve b. At the intersection of the back-pressure special back-pressure radiator upper port 04 and the back-pressure special back-pressure radiator lower port 06, there is a ball valve c.

[0061] In a possible implementation, 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, the ball valve a is provided with two channels. Among them, the channel a1 is used to connect the engine outlet hot water port interface 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 port 011;

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

[0064] The ball valve c is provided with two channels. Among them, the channel c1 is used to connect the ball valve b, the back-pressure special back-pressure 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 back-pressure special back-pressure radiator upper outlet interface, and the automotive heating boiler heater outlet port 041;

[0065] A car heating boiler heater water outlet 041 is provided at the tee lower bend of the upper port 04 of the back pressure special back pressure type radiator, which is connected to the water outlet of the car heating boiler 1, and 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 inlet 061 of the water pump.

[0066] In a possible implementation, a tee is provided downward at the lower bend of the tee to connect the supporting heating type tank heater and the heating vehicle heating boiler with the water inlet and outlet of the water pump. The tee is drilled downward through a plate to connect an external L-shaped pipe for docking with the tee in the cab.

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

[0068] In a possible implementation, 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 to play a fixing role.

[0069] In a possible implementation, Figure 3 As shown, in the operation of the vehicle in summer, there are two channels in the ball valve a, of which channel a1 is used to connect the hot water outlet 07 of the engine small circulation and the cold water return outlet 01 of the engine small circulation, and channel a2 is used to connect the small water tank of the car and the T-type valve. At this time, channel a2 is in the non-working state of the small water tank in the car cab, and the water circulation in channel a1 directly flows back to the large circulation system of the engine, so that there is no hot air in the cab in summer.

[0070] Working principle:

[0071] like Figure 3 As shown, in summer, the water flows from the hot water interface of the engine's small circulation outlet to the a1 channel of the conversion valve 1, connects 07 to flow to 01 and then directly returns to the engine's small circulation 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 a possible implementation, Figure 4As shown, in winter vehicle operation, two channels are provided in ball valve a, wherein channel a1 is used to connect the engine small circulation hot water outlet O7 and T-type valve b, and channel a2 is used to connect the cab small water tank outlet 02 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-type 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 aH 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 dedicated to back pressure, the automobile heating boiler water pump 061, and channel c2 is used to connect the upper port of the back radiator, the automobile boiler main 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, it works 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 water outlet of the car heating boiler heater (04-041) → the water inlet interface 05 of the cab small water tank → the water outlet 02 of the cab small water tank → the engine cold water return interface 01 and the water inlet of the No. 0 matching heating type oil tank heater → the engine small cycle main body engine → the engine small cycle water outlet hot water outlet 07 → the T-type valve b1 connected to the No. 0 matching heating type oil tank heater outlet 03, b2 → C1 → the lower port 06 of the back pressure special back pressure radiator, the car heating boiler water pump inlet 061 → the car heating boiler water pump main body 08, to realize a whole cycle. When the water pressure is low, due to the high installation position of the back pressure radiator, the water inlet interface 06 below the back pressure radiator → the water outlet interface 04 above the back pressure radiator is slow when the heating is not started. The matching heating type oil tank heater water inlet and outlet interface 03 → matching heating type oil tank heater water outlet interface 011 is not started in winter, sometimes it is necessary to be in T-type closure first and then open. The main reason is to ensure that the engine is preheated first, and then the oil circuit is preheated. The oil circuit of the engine and the matching heating type oil tank are connected. The water resistance of the oil circuit is smaller than the water resistance of the engine, so the preheating of the oil circuit is fast. When the engine is preheated successfully, the oil in the engine has no wax. At the right time, open the T-valve to start preheating the matching heating type oil tank for three minutes to dewax the matching heating type oil tank, so that the diesel engine can start normally with zero diesel within minus sixty degrees. The water circuit resistance of the matching heating type oil tank is less than the water circuit resistance of the engine, and the water circuit resistance of the engine is less than the resistance of the back pressure radiator. In winter, when the engine is started and in use, the car heating boiler and the engine can be used at the same time. After the engine is working normally, turn off the car heating boiler, and the matching heating tank can also work normally. When the engine speed reaches more than 1,600 revolutions, the resistance of the back pressure radiator is roughly equal. When the engine speed is higher than 1,800 revolutions, it is greater than the resistance of the back pressure radiator. At this time, the back pressure radiator can be heated normally. The purpose of heating and reducing pressure is achieved. The hot water interface 07 of the engine outlet and the return water interface 01 of the engine cold water outlet.

[0076] In a 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 inlet of the water pump → 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 tank to form a circulation, wherein the automobile heating boiler water pump 08 → the automobile automobile heating boiler body 09 → the automobile heating boiler heater water 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 circulation.

[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 radiator dedicated for back pressure → 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 radiator dedicated for back pressure and the T-type valve b2 channel.

[0079] Working principle:

[0080] like Figure 5 As shown, when you stop on the road. The whole cycle is formed by the car heating boiler booster water pump water inlet interface 061 → car heating boiler heater pump main body interface 08 → car car heating boiler main body 09 → car heating boiler power heater outlet 041 interface → back pressure special back pressure type radiator upper water inlet interface 04 and C2 → back pressure special back pressure type radiator main body and cab small water tank → back pressure special back pressure type radiator lower port 06 and (C2→b2→a2→02) car small water tank outlet 02 → back pressure special back pressure type radiator lower port 06 and car small water tank water inlet 05 → water pump water inlet 061.
