Description

Novel evaporator

Technical Field

The invention relates to a novel evaporator, and belongs to the technical field of evaporators.

Background

In the automobile air-conditioning refrigeration system, an evaporator is used for directly contacting with air in an automobile which is a cooled object, and the working principle is as follows: the liquid refrigerant with medium temperature and high pressure flows into the evaporator after passing through the throttling device, and absorbs the heat of the space through the devices such as the inner wall, the outer wall and the fins of the pipeline, so that the refrigerant is gasified and changed into refrigerant gas with low temperature and low pressure, thereby achieving the purposes of refrigeration and cooling

The purpose is.

The evaporimeter has superior refrigeration performance, it is compact, rigid structure and stronger corrosion resistance, current evaporimeter often all makes up through the evaporation slab and forms, the slab is very thin, both sides need advance very accurately when fixed go to compare, and often can cause phenomenons such as not fastening after the combination, the evaporimeter can be damaged in long-time use, and ordinary slab also is a rectangular expert, the refrigerant gets into the other end from one end and flows, apart from very end, and the circulation is also not enough, just lead to the very low on evaporimeter working effect limit, refrigeration effect is not strong, rivers are slow, easily cause the rivers not smooth and leak, freeze the scheduling problem, reduce refrigeration efficiency.

Disclosure of Invention

The utility model aims at solving the shortcoming that exists among the prior art, let set up a space on the slab, let the import can then circulate through the way down along with a pipeline, let the steam liquid of import can be more abundant cool off to go on circulating at the lower extreme, let whole circulation more.

The invention is completed by the following technical scheme: the novel evaporator comprises an evaporator body consisting of a plurality of evaporation plates, wherein side plates for fastening the plates are arranged on two sides of each evaporation plate respectively, an air inlet and outlet pipe for air and liquid to enter and exit is formed in the evaporation plate at the topmost end of one side edge, a pipeline is arranged in the air inlet and outlet pipe, the diameter of the air inlet pipe is smaller than that of the air outlet pipe, a long-strip-shaped through hole is formed in the middle position of the adjacent evaporation plates after combination, and a wave-shaped fin is arranged in the through hole.

Preferably, the method comprises the following steps: the two evaporation plate sheets are combined into one layer, 22 layers of evaporation plate sheets are arranged in total and are connected end to end, a left and right separated gap is formed in the middle of the front 14 layer plate sheets, gas is allowed to circulate on one side only, and the rear 8 layer plate sheets are communicated left and right, so that the gas can form a large loop.

Preferably, the method comprises the following steps: four corners all are equipped with inside sunken recess around two of topmost and least significant end of evaporating plate piece, and this recess is integrative with sideboard arch looks welded fastening, forms parallel top surface and bottom surface, lets more fixed of both sides.

The utility model has the advantages that: the device simple structure, through the design of upper and lower sideboard and slab, the effectual aversion that prevents in the installation to through the left and right sides design of liquid pipe and the liquid pipe of giving vent to anger of admitting air, let the refrigerant in inside mobility higher, refrigeration effect is better, and sealing performance is also very good, very big improvement work efficiency, improvement refrigerated effect.

Detailed Description

The invention will be described in detail below with reference to the following drawings: as shown in fig. 1-2, a new evaporator comprises an evaporator body 2 composed of a plurality of evaporating plates 1, wherein two sides of the evaporating plates 1 are respectively provided with side plates 3 for fastening the plates, the evaporating plate 1 at the topmost end of one side edge is provided with a liquid inlet 4 and a liquid outlet 5 for allowing gas and liquid to enter and exit, the liquid inlet 4 and the liquid outlet 5 are both provided with pipelines 6, the pipeline of the liquid inlet 4 is smaller than that of the liquid outlet 5, after the adjacent evaporating plates are combined, the middle position is provided with a strip-shaped through hole 7, the through hole 7 is internally provided with a wave-shaped fin 8, the two evaporating plates 1 are combined into one layer, 22 layers of heads and tails are mutually connected, the middle of the front layer plate 14 is provided with a left-right separated gap 9 for allowing gas to flow only on one side edge, the back 8 layers of plates are communicated left and right, let gas can form a big return circuit, four corners all are equipped with inside sunken recess 10 around two slices of topmost and least significant end of evaporating board piece 1, and this recess is integrative with sideboard arch looks welded fastening, forms parallel top surface and bottom surface, lets more fixed of both sides.

As shown in fig. 1-2: the evaporator enters through the air inlet liquid port, flows to the other side through one side edge, then returns through the bottom of the other side and returns to the other side, and flows out of the air outlet liquid port through the single-side runner at the other side, so that the air and liquid are more uniform in the interior, the air flow is more stable, the refrigeration effect is better, the bottom is provided with the side plate, the side plate and the plate sheet at the bottom are complemented to form a parallel bottom surface, the design can enable the two sides to be more fastened, the evaporator can be suitable for various occasions, and the evaporator is more attractive after installation.
