Abstract

The utility model discloses an engine water circulation heating device, wherein, an upper water pipe and a lower water pipe connected on the engine are communicated with a water inlet pipe and a water returning pipe which are connected with a heat exchanger via a water inlet cut-off valve and a water returning cut-off valve. Between the heat exchanger and a carriage air duct is provided with a blower. The utility model supplies heat by engine cooling water, thus being able to reduce cost, save energy and keep the air in the carriage clean.

Description

The driving engine water circulation heating device

Technical field

The utility model relates to a kind of driving engine water circulation heating device.

Background technology

The available engine water circulation heating device is to connect a diversion box on engine water tank, utilizes the heat of water in the diversion box to heat in car by H Exch.Because heat is not enough, this structure only is installed on the miniature car usually.For large and medium-sized bus, institute's heat requirement is bigger, just installs one and overlap independently heating installation on bus, and the heat that utilizes the burning of diesel combustion material to produce heats in the bus compartment.The consumption of fuel had not only wasted energy but also contaminated environment like this, on the one hand; If poorly sealed, can make waste gas after burning suck the compartment on the other hand, cause occupant's discomfort.And this heating installation both increased automotive dead weight, increased the car production cost again.

Summary of the invention

The purpose of this utility model is need not set up diesel engine in addition in order to provide a kind of, not only energy savings but also can keep with fresh air in the car, and simple in structure, the driving engine water circulation heating device of favourable reduction car production cost.

Main technical schemes of the present utility model is: bonded assembly Upper hose, Lower hose are communicated with coolant inlet pipe, return water pipe on being connected H Exch by water inlet shutoff valve, backwater shutoff valve respectively on the engine water tank, between H Exch and the air channel, compartment blower fan are housed.

The utility model is opened into water shutoff valve in the normal state, turn-offs the backwater shutoff valve, at this moment utilizes engine water device for cooling Central Plains that water pump is arranged, and cooling water expansion tank circulates between driving engine and engine water tank.If under the warm braw state, the utility model is opened the backwater shutoff valve, turn-offs the water inlet shutoff valve, and at this moment cooling water expansion tank circulates between driving engine and H Exch, thereby the heat that will take out of from driving engine passes to air intake by H Exch, heats in the compartment.Shutoff valve of the present utility model can be the automatically controlled shutoff valve of stepping formula, and it can the stepping control cock opens, the shutoff degree, change the flow size, thereby control participates in the amount of heat of interchange of heat, make vehicle interior temperature can height can be low.As seen, the utility model heating institute heat requirement need not to set up separated diesel-engine from engine cooling water, and sends into and can not have unpleasant diesel oil in the warm compartment in and distinguish the flavor of.The utility model is simple in structure, has also reduced the cost of automobile simultaneously.The utility model can be applied in big-and-middle-sized bus, steamer and other and have on the facility that watercooled engine and needs heat.

Description of drawings

The utility model is described in further detail below in conjunction with the drawings and specific embodiments:

Fig. 1 is the structural representation of an embodiment of the utility model.

The specific embodiment

As shown in Figure 1, present embodiment and rear-mounted engine are installed in big bus tailstock portion, bonded assembly Upper hose 2, Lower hose 3 are communicated with coolant inlet pipe 7, return water pipe 8 on being connected H Exch 6 by water inlet shutoff valve 4, backwater shutoff valve 5 respectively on the engine water tank 1, between H Exch 6 and the air channel, compartment 9 blower fan 10 are housed.

Setting height(from bottom) is than water tank 1 height in car for H Exch 6 in the present embodiment, and H Exch 6 tops connect filler pipe 11.Can keep injecting in the whole water circulation pipe enough cooling water expansion tanks like this.

Claims
