Abstract
The utility model discloses an air conditioner for a small-sized engineering truck, and relates to the technical field of air conditioner manufacture. The air conditioner comprises an evaporator, a heater and an air feeder, wherein the evaporator, the heater and the air feeder are installed in a casing; an airflow passage is formed from an air inlet at one end of the casing to an air outlet at the other end of the casing; the evaporator is transversely arranged above the airflow passage close to one end of the air inlet; the evaporator is arranged in an inclined manner, and an included angle ranging from 10 to 20 degrees is formed between a main flow board of the evaporator and a horizontal plane; the heater and the air feeder are arranged behind the evaporator above the airflow passage; and a pressure balancing gas chamber is arranged from an air outlet of the air feeder to the air outlet of the airflow passage. Compared with the prior art, the air conditioner can solve the problems that the size of the air conditioner for the small-sized engineering truck is larger, the content of condensed water is larger, and the heat exchanging rate of the evaporator is lower.
Description
Technical field
The utility model relates to air-conditioning manufacturing technology field, especially a kind of air conditioner for mini engineering car driver's cabin.
Background technology
Engineering truck is relatively worked under rugged environment in high temperature, severe cold, uneven physical features etc. usually, and the driver's cabin of engineering truck or operating room all need configure air conditioner and provide comfortable environment for the staff.Yet, in most cases the restriction of operation and its driver's cabin small space under rugged environment relatively owing to being subjected to engineering truck, mini engineering car particularly, the volume of its air conditioner and modes of emplacement are to air conditioner efficient, and the air-conditioning actual effect all can be subject to larger impact.In existing technology, the evaporimeter of air conditioner vertically arranges and causes the air conditioner volume larger, and condensed water content is more in evaporator fin, and windage is large, and impeded drainage causes the evaporimeter heat transfer rate lower.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of mini engineering car air-conditioner, and it can solve in existing technology, and the air conditioner volume is larger, the problem that condensed water content is more and the evaporimeter heat transfer rate is lower.
In order to address the above problem, the technical solution of the utility model is: this mini engineering car air-conditioner includes the evaporimeter, heater and the pressure fan that are arranged in housing; The air intake of described housing one end forms a gas channel to the air outlet slit of the other end, described evaporimeter is horizontally installed near on the described gas channel of described air intake one end, its main flow plate becomes 10 degree to 20 degree to be obliquely installed with horizontal plane angle, after described heater and pressure fan are located at described evaporimeter on described gas channel; Be provided with equal plenum chamber in pressure fan air outlet side between described gas channel air outlet slit.
In technique scheme, more specifically scheme can be: described evaporimeter is laminated evaporator.
Owing to having adopted technique scheme, compared with the prior art the utility model has following beneficial effect:
1, the utility model evaporimeter adopts laminated evaporator, evaporimeter is laterally put, and its main flow plate becomes 10 degree to be inclined on gas channel in housing to 20 degree with horizontal plane angle, and condensed water content is less in evaporator fin, draining is unimpeded, and the evaporimeter heat transfer rate is higher.
2, be provided with equal plenum chamber in pressure fan air outlet side and can significantly reduce wind loss.
3, pressure fan is located at air outlet, becomes air draught type from bleed type, and windage is little, and efficient is higher.
4, the air conditioner height dimension is less, can be arranged in driver's under-seat.
Description of drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is top view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail:
Mini engineering car air-conditioner illustrated in figures 1 and 2 includes the laminated evaporator 1, heater 2 and the pressure fan 3 that are arranged in housing 4; Air outlet slit 6 from the air intake 7 of housing 4 one ends to the other end, housing 4 inner chambers form a gas channel, evaporimeter 1 is horizontally installed on housing 4 near on the gas channel of described air intake 7 one ends, and its main flow plate and horizontal plane angle A are 15 degree, the interior condensed water content of evaporimeter 1 fin this moment can be fewer, and evaporimeter 1 heat exchange efficiency is improved; Heater 2 and pressure fan 3 are arranged on evaporimeter 1 described gas channel afterwards; Be provided with equal plenum chamber 5 in pressure fan 3 air outlet sides between described gas channel air outlet slit 6, this set can significantly lower wind loss.
Claims (2)
1. a mini engineering car air-conditioner, include the evaporimeter (1), heater (2) and the pressure fan (3) that are arranged in housing (4); The air intake (7) of described housing (4) one ends forms a gas channel to the air outlet slit (6) of the other end, it is characterized in that: described evaporimeter (1) is horizontally installed near on the described gas channel of described air intake (7) one ends, its main flow plate become with horizontal plane angle 10 the degree to 20 the degree be obliquely installed, described heater (2) and pressure fan (3) be located on described gas channel described evaporimeter (1) afterwards; Be provided with equal plenum chamber (5) in pressure fan (3) air outlet side between described gas channel air outlet slit (6).
2. mini engineering car air-conditioner according to claim 1, it is characterized in that: described evaporimeter (1) is laminated evaporator.
