Abstract
The utility model relates to an installation technology for an engine heat radiator of an urban passenger bus. In order to solve the technical problems of the existing engine chamber built-in structure of the passenger bus heat radiator, such as multiple water pipe curves, large air flow resistance, complicated arrangement structure and difficulty for the heat radiation of the engine, the utility model provides the urban passenger bus with an overhead engine heat radiator, wherein an automobile engine heat radiator is arranged at the top of the passenger bus. The technology has the advantages that the top open space of the bus is fully used for arranging the heat radiator, the original forced air-cooling fan and a fan motor controller can be saved, the installing structure of heat radiating water-cooling pipes is simplified, the installing space in the engine chamber is saved, and the cost is effectively reduced.
Description
Technical field
The utility model relates to engine heat dissipating device, in particular the field engineering of bus engine radiator.
Background technology
Can produce the combustion gas (being about 800-2000 ℃) of HTHP behind the indoor mixture combustion of engine combustion.So must cool off cylinder, otherwise movement parts expanded by heating wherein and destroyed normal clearance, mechanical strength to reduce and damage, lubrication failure and stuck.If undercooling also can cause influences such as cylinder charge minimizing, burning mal, power decline, consumption increase and insufficient lubrication.
Automotive engine adopts the forced circulation water-cooling system more at present.Water jacket is all arranged in engine cylinder cap and the cylinder block.Water pump sucks pressurization outward with the cooling water expansion tank slave, and cold water is flowed in water jacket, takes away the heat of adjacent components.Cooling water expansion tank heat absorption back self temperature build-up gets in the radiator (water tank).Because automobile advances and the suction of fan, cool ambient air is taken away the heat of cooling water expansion tank in the radiator and is sent into atmosphere through radiator.After the cooling water expansion tank in the radiator obtains cooling, under the effect of water pump, get into water jacket once more.So circulation cooling the high-temperature component of driving engine.
Automobile radiators is as the vitals of bus engine cooling system, and its installation is provided with the installation of generally adopting in the machinery space structure is set.The technical problem underlying that this mounting structure exists is: radiator is installed in the higher machinery space of temperature, causes Engine Inlet Temperature higher equally, and is totally unfavorable to engine radiating; This set-up mode has occupied between limited engine air, has brought very big difficulty on the one hand the maintenance of driving engine, and its body be provided with structure also be easy to this cabin in other annexes in space confused is set, be unfavorable for the car load setting of each parts.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, provide a kind of simple in structure, effectively realize engine radiating and the engine radiator field engineering of practicing thrift cost, saving the machinery space installing space.
The technical matters that the utility model solves takes following technical scheme to realize:
A kind of engine radiator overhead type city bus, it is characterized in that: its engine radiator places the passenger vehicle top, is exposed in the air.
Said engine radiator can adopt fin and tube core, and promptly respectively there is a water storage room at the radiator two ends, links to each other with some cooling pipes therebetween, outside cooling pipe, puts and has arranged many metal fins.
Said engine radiator can adopt the pipe rock radiator core, is formed alternately by corrugated heat-radiation belt and cooling pipe, on heat-radiation belt, has the winglet of rough air.
Fill in the said engine radiator and add anti-freezer, connect a receiver in the radiator exhaust ports, when expanded by heating, anti-freezer just gets into receiver; During drop in temperature, anti-freezer is inhaled back in the radiator in jar.
Said engine radiator the place ahead installs louver additional, and the switching degree that changes louver can be adjusted the amount of air through radiator.
The utility model compared with prior art has significant advantage and beneficial effect, is embodied in the following aspects:
Compare traditional radiator machinery space built-in mechanism, the engine radiator of the utility model places the passenger vehicle top, has removed the installing space restriction, can strengthen the area of radiator, saves space in the machinery space, improves the radiating effect of driving engine better.
Radiator places the passenger vehicle top; The circulating air that produces when utilizing the passenger vehicle motion cools off cooling water expansion tank, can need not to re-use fan in the present embodiment and carry out force-air cooling, so the heat dissipating package cooling system can dispense radiator fan and corresponding fan electromotor controller; Simplified the component mounting structure in the machinery space; Reduce the cost of cooling system, save energy consumption of vehicles, for passenger vehicle inside bigger space is provided simultaneously.
Description of drawings
Fig. 1 is the utility model engine radiator overhead type city bus structural representation;
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is done further detailed description:
As shown in Figure 1, the 1st, machinery space, the 2nd, radiator, the 3rd, car body.
The heat sink mounting structure scheme drawing of the engine radiator overhead type city bus of the utility model is shown in accompanying drawing 1; Its radiator 2 is fixedly mounted on top, the rear portion roof of passenger car body 3; Bus engine and cooling system water pump are installed in the machinery space 1 of passenger vehicle afterbody, and the inlet and outlet pipe lines of radiator 2 passes passenger car body 3 back wall spatial communication to engine cooling water jackets and forms the heat radiation circulation waterway.
Its mode of operation is: water pump sucks pressurization outward with the cooling water expansion tank slave, makes in the water jacket of cold water in engine cylinder cap and cylinder block to flow, and takes away the heat of adjacent components.Cooling water expansion tank heat absorption back self temperature build-up gets in the radiator at passenger vehicle top.Because bus driving advances, outside air is taken away the heat of cooling water expansion tank in the radiator and is sent into atmosphere through radiator.After the cooling water expansion tank in the radiator obtains cooling, under the effect of water pump, get into water jacket once more.So cooled off the high-temperature component of driving engine circularly.
