Description

A kind of automobile-used radiator return pipe arrangement

Technical field

Car engine cooling system technical field is the utility model is related to, particularly a kind of automobile-used radiator return pipe Arrangement.

Background technology

For the fuel tank of automobile under different weather conditions, requirement is different：Under southern temperature climate, it is not required to Automobile engine normal operation can just be made by fuel oil in fuel tank being heated, but in northern cold winter, fuel oil Particularly the viscosity increase of diesel oil, mobility and atomizing effect are deteriorated, burn insufficient, therefore oil consumption increase, discharge smog increase Greatly, each several part filter net jam is caused when serious, sufficient fuel can not be provided to engine, so as to cause engine misses；Separately On the one hand, in order to reduce amount of nitrogen oxides in vehicle exhaust, reduce tail gas pollution, reduce oil consumption, reduce cost, partial automobile Urea box is mounted with also, is had no problem in warm regional use, but under the conditions of northern cold chill temperature, urea easily freezes, Its function can not effectively be played.

Therefore under northern cold snap, it is often necessary to the fuel tank and urea box of automobile are heated, but in southern temperature Under warm climate, it is not necessary to which fuel tank and urea box are heated.

At present, generally taken over using from engine cooling water jacket delivery port, draw hot water and fuel tank and urea box are carried out Heating, then from the adapter of the delivery port of fuel tank heater and urea box heater to the water inlet of radiator, water is drained To after radiator, engine cooling water jacket is returned to by the delivery port of radiator, radiator return pipe and completes water circulation.So, Other perforate on a heat sink is not only needed, can also increase duct length and related components kind, increases manufacturing cost.

In addition, automobile radiators return pipe is typically fixed using structural members such as vehicle frames, structure is not compact.

Utility model content

The problem of in background technology, the utility model provide a kind of automobile-used radiator return pipe arrangement, with Solve in the prior art, pipeline is complicated, parts kind is more, structure is not tight caused by due to being heated to fuel tank and urea box Gather, the problem of cost is higher.

The purpose of this utility model realizes that it includes by such technical scheme：

A kind of automobile-used radiator return pipe arrangement, it is characterised in that：The radiator water return pipeline includes starting Machine cooling jacket, radiator, expansion tank, fuel tank heater, urea box heater, return pipe and motor body； One end of the return pipe is designated as water inlet, and the other end is designated as delivery port；Water supplement port, first are provided with the middle part of the return pipe Water return outlet and the second water return outlet；The water inlet, delivery port, water supplement port, the first water return outlet and the second water return outlet pass through return pipe Inner chamber connection；The water inlet connects with the delivery port of radiator, the water inlet of the delivery port and engine cooling water jacket Connection, the water supplement port connect with the delivery port of the expansion tank, first water return outlet and the fuel tank heater Delivery port connection, second water return outlet connects with the delivery port of the urea box heater；In the motor body On be provided with support, the support connects with return pipe.

Preferably, the fuel tank water return outlet, urea box water return outlet are close to export.

By adopting the above-described technical solution, the utility model has the following advantages：Due to fuel tank heater and The delivery port of urea box heating dress is directly connected with return pipe, radiator is arrived without individually adapter, without on a heat sink Other perforate, length of pipe was both shortened, reduced parts kind, reduce cost, has also saved installing space；Due to Directly set support to connect on motor body, fixed return pipe, return pipe is arranged near engine, makes structure tighter Gather, bearing strength it is higher；Fuel tank water return outlet and urea box water return outlet are arranged on return pipe near exit, further shorten Intermediate connection tube road length.

Embodiment

The utility model is described in further detail with reference to the accompanying drawings and examples.

Automobile radiators water return pipeline as shown in accompanying drawing 1- accompanying drawings 2, engine cooling water jacket 1, radiator 2, swelling water Case 3, fuel tank heater 4, urea box heater 5, return pipe 6 and motor body 7.

One end of return pipe 6 is designated as import 61, and the import 61 connects with the delivery port of radiator 2, the other end of return pipe 6 Outlet 62 is designated as, the outlet 62 connects with the water inlet of engine cooling water jacket 1.It is cold by the effect of cooling water pump, engine But the hot water inflow radiator 2 of water jacket 1, cooling water after cooling flows out from the delivery port of radiator 2, by return pipe 6, then Engine cooling water jacket 1 is flowed back to, engine is cooled down.

The middle part of return pipe 6 is provided with water supplement port 63, fuel tank water return outlet 64 and urea box water return outlet 65, fuel tank backwater Mouth 64 and urea box water return outlet 65 are all disposed within the outlet 62 of return pipe 6, so can be shortened centre to greatest extent and be connected Take over the length on road；Import 61, outlet 62, water supplement port 63, fuel tank water return outlet 64 and urea box water return outlet 65 pass through return pipe 6 Inner chamber connection.

The delivery port of expansion tank 3 connects with the water supplement port 63 on return pipe 6, and the cooling water in expansion tank 3 can pass through The inflow return pipe 6 of water supplement port 63 completes the supplement to cooling water.

Fuel tank heater 4 is to be arranged on a disc-shaped heating pipe in fuel tank, in the heating pipe Water and the fuel oil in fuel tank are mutually isolated, and heating pipe inner chamber connection, its both ends are passed outside fuel tank, and one end is with starting The delivery port connection of machine cooling jacket 1, the other end connect with the fuel tank water return outlet 64 on return pipe 6.Engine cooling water jacket 1 Hot water flow through heating pipe inside fuel tank and complete heating to fuel oil, after hot water is cooled down by fuel oil, from fuel tank backwater Mouth 64 flows into return pipes 6, then flows back to engine cooling water by the outlet 62 of return pipe 6, the water inlet of engine cooling water jacket 1 Set is circulated.

Urea box heater 5 is a heating water jacket for being coated on urea box periphery, and the heating water jacket has a water inlet Mouth and a delivery port, the water inlet of heating water jacket are connected with the delivery port of engine cooling water jacket 1, the delivery port of heating water jacket Connected with the urea box water return outlet 65 on return pipe 6.The heating water jacket that the hot water of engine cooling water jacket 1 flows through urea box completes Heating to urea box, after hot water is cooled down by urea box, return pipe 6 is flowed into from urea box water return outlet 64, then pass through return pipe 6 Outlet 62, the water inlet of engine cooling water jacket 1 flow back to engine cooling water jacket and circulated.

For the vehicle mainly used under the conditions of the temperature climates such as south, due to need not enter to fuel tank and urea box Row heating, therefore return pipe 6 need not be connected with fuel tank heater 4 and urea box heater 5, as shown in Figure 3, in order to Do not change pipeline structure, it is only necessary to be threaded on the fuel tank water return outlet 64 and urea box water return outlet 65 of return pipe 6, use spiral shell Line plug 9 blocks above-mentioned two water return outlet.
