Description
Technical Field
The utility model relates to a bull-dozer especially relates to an air conditioner for bull-dozer.
Background
The bulldozer is an engineering vehicle, a large-sized metal blade is arranged in front of the bulldozer, the blade is put down when the bulldozer is used, sand, stones and the like are shoveled and pushed forwards, and a scarifier device can be optionally matched with a rear working device, so that the bulldozer can be used for cracking frozen soil and broken stones. The air conditioner is arranged in the bulldozer, and the temperature and humidity in the cab of the bulldozer can be adjusted. At present, a warm air structure of an air conditioning system of a bulldozer mostly adopts a mode of arranging an evaporator under a seat, the mode can meet the requirements of most working conditions, but the hot air structure is not easy to worry about extremely cold working conditions, and mainly solves the problems of low temperature rising speed, low temperature and the like in a cab.
In the existing warm air structure of the air conditioning system of the bulldozer, as shown in the attached drawing 2, an evaporator is arranged below a seat, and hot water of an engine is connected with the evaporator through a valve and a water inlet pipe and then flows to a radiator through a water return pipe and the valve to form a water circulation. Because bulldozer driver's cabin interior space is limited, lead to the evaporimeter size limited, heat exchange efficiency is poor, so when facing extremely cold type operating mode, current air conditioning system heating capacity often can not satisfy the demand, leads to driver's travelling comfort to experience relatively poorly.
Disclosure of Invention
In order to solve the problem, the utility model provides an air conditioner for bull-dozer provides the higher air conditioner for bull-dozer of heat exchange efficiency. In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides an air conditioner for bull-dozer, includes return water valve, inlet valve, reposition of redundant personnel piece, evaporimeter, heater, inlet tube, wet return and pipeline, the evaporimeter setting in the below of bull-dozer driver's cabin seat, the heater setting in the inside of bull-dozer instrument case, inlet valve be connected with reposition of redundant personnel piece through the inlet tube, return water valve be connected with reposition of redundant personnel piece through the wet return, the evaporimeter be connected with reposition of redundant personnel piece through the pipeline, the heater is connected with reposition of redundant personnel piece through the pipeline.
Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses under the limited circumstances in bull-dozer space, parallelly connected with the evaporimeter through the heater, simple structure, the limited space of make full use of has effectively improved the heat exchange efficiency of air conditioner, can obviously promote driver's cabin temperature and programming rate, has improved driver's comfort level.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
FIG. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic view of the structure of a prior art bulldozer air conditioner;
in the drawings: 1. the system comprises a water return valve 2, a water inlet valve 3, a flow dividing block 4, an evaporator 5, a heater 6, a main water inlet pipe 7, a main water return pipe 8, a circulating heating water inlet pipe 9, a circulating heating water return pipe 10, an evaporation water inlet pipe 11 and an evaporation water return pipe.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described with reference to fig. 1 and the specific embodiments.
As shown in the attached drawing 1, an air conditioner for a bulldozer comprises a water return valve 1, a water inlet valve 2, a flow dividing block 3, an evaporator 4, a heater 5, a main water inlet pipe 6, a main water return pipe 7, a circulation heating water inlet pipe 8, a circulation heating water return pipe 9, an evaporation water inlet pipe 10 and an evaporation water return pipe 11, wherein the water inlet valve 2 is connected with the flow dividing block 3 through the main water inlet pipe 6, the water return valve 1 is connected with the flow dividing block 3 through the main water return pipe 7, the evaporator 4 is connected with the flow dividing block 3 through the evaporation water inlet pipe 10 and the evaporation water return pipe 11, and the heater 5 is connected with the flow dividing block through the circulation heating water inlet pipe 8 and the circulation heating water return pipe 9.
Further, the evaporator 4 is disposed below the bulldozer cab seat.
Further, the heater 5 is provided inside the bulldozer meter box.
The utility model discloses a theory of operation and working process as follows: the structure form of the parallel connection mode of the heater 5 and the evaporator 4 is adopted, the flow dividing block 3 is respectively connected with the heater 5 and the evaporator 4 through pipelines to form two independent small circulation systems, and then the two independent small circulation systems are collected into a main water return pipeline through the flow dividing block 3. The utility model discloses under the limited condition in bull-dozer space, parallelly connected with evaporimeter 4 through heater 5, the limited space of make full use of has effectively improved the heat exchange efficiency of air conditioner, can obviously promote driver's cabin temperature and programming rate, has improved driver's comfort level.
Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses under the limited circumstances in bull-dozer space, parallelly connected with the evaporimeter through the heater, simple structure, the limited space of make full use of has effectively improved the heat exchange efficiency of air conditioner, can obviously promote driver's cabin temperature and programming rate, has improved driver's comfort level.
Utilize technical scheme, or technical personnel in the field are in the utility model discloses under technical scheme's the inspiration, design similar technical scheme, and reach above-mentioned technological effect, all fall into the utility model discloses a protection scope.
