Abstract
The utility model relates to the field of heat exchangers, in particular to a parallel flow heat exchanger. The parallel flow heat exchanger comprises refrigerant pipes, fins and refrigerant manifolds, wherein more than one refrigerant pipe is parallel to each other; the fins are connected between the refrigerant pipes; and two ends of the refrigerant pipes are respectively connected with the refrigerant manifolds. By the parallel flow heat exchanger, a field synergy principle is utilized, namely an included angle between a velocity field and a temperature field is reduced, and air side heat transfer can be effectively intensified; the parallel flow heat exchanger has high specific surface area and serves as a compact heat exchanger, and the heat exchange efficiency can be effectively improved in an automotive air conditioner; and meanwhile, compared with other heat exchangers, the parallel flow heat exchanger has the advantages that the refrigerant charge required by a refrigeration system is greatly reduced, and the air side pressure drop is greatly reduced.
Description
Technical field
The utility model relates to a kind of heat exchanger, specifically a kind of parallel-flow heat exchanger.
Background technology
Heat exchanger is with the equipment of the part heat transferred cold fluid of hot fluid, claims again heat exchanger.Heat exchanger is the common apparatus of chemical industry, oil, power, food and other many industrial departments, occupies aborning critical role.And air conditioning for automobiles is limited by spatial constraints, and its heat exchanger specific area is not high, thereby heat exchange efficiency can't satisfy the demands.
Summary of the invention
Primary and foremost purpose of the present utility model is to provide a kind of parallel-flow heat exchanger of Effective Raise heat exchange efficiency, and for achieving the above object, concrete scheme of the present utility model is as follows:
A kind of parallel-flow heat exchanger comprises refrigerant pipe, fin and cold-producing medium manifold; Described refrigerant pipe is setting parallel to each other more than, is connected with described fin between the described refrigerant pipe; Described refrigerant pipe two ends are connected with respectively described cold-producing medium manifold.
Preferably, described refrigerant pipe is flat.
Preferably, be provided with microchannel parallel to each other in the described refrigerant pipe.
The parallel-flow heat exchanger that the utility model provides utilizes a synergistic principle, namely reduces the angle in velocity field and temperature field, but the efficient hardening air side is conducted heat; Parallel-flow heat exchanger has higher specific area, but as compact heat exchanger Effective Raise heat exchange efficiency in air conditioning for automobiles; Simultaneously, compare with other heat exchangers, the required refrigerant charge of its refrigeration system greatly reduces, and air wide pre. drop also reduces much.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, consists of the application's a part, does not consist of to improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the utility model example structure schematic diagram.
The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.
Embodiment
As shown in Figure 1, a kind of parallel-flow heat exchanger comprises refrigerant pipe 1, fin 2 and cold-producing medium manifold 3; Described refrigerant pipe 1 is setting parallel to each other more than, is connected with described fin 2 between the described refrigerant pipe 1; Described refrigerant pipe 1 two ends are connected with respectively described cold-producing medium manifold 3, and cold-producing medium manifold 3 is two pipes that internal diameter is slightly large, are used for refrigerant is shunted and gathered.
As the preferred version of above-described embodiment scheme, described refrigerant pipe 1 is flat.
As the preferred version of above-described embodiment scheme, be provided with microchannel parallel to each other in the described refrigerant pipe 1.
In above-described embodiment scheme, refrigerant pipe 1 is arranged in parallel, and two ends are connected with cold-producing medium manifold 3 respectively, and refrigerant pipe 1 is divided into two passages, a passage is used for the gaseous refrigerant of cooling down high-temperature high pressure, and another passage is used for finishing condensation and carried out cold to cold-producing medium.Refrigerant pipe 1 has good heat exchange property at medium side, and in air side, parallel-flow heat exchanger adopts ripple type louvered fin 2, can effectively destroy the Air Flow boundary layer, increases disturbance, enhanced heat exchange.Refrigerant pipe 1 can reduce the air side flow resistance greatly at the small-sized of cross-wise direction that facing the wind, and the fin 2 of optimal design has strengthened heat-exchange performance.
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, all will change on the specific embodiment and range of application, in sum, this description should not be construed as restriction of the present utility model.
