Description

Novel advection heat exchanger

Technical field

This utility model relates to refrigerating field, particularly to a kind of novel advection heat exchanger。

Background technology

Parallel-flow heat exchanger conventional at present is usually micro-channel flat parallel-flow heat exchanger, and its agent structure includes micro-channel flat and U-shaped louvered fin, and both are fixed by soldering。In order to ensure between louvered fin and micro-channel flat can heat exchange well, reduce thermal contact resistance between the two, usual fin be all tight welding between flat tube。But, so cause that, when heat exchanger is horizontal, flat tube can stop flowing down of condensed water；When heat exchanger is vertically arranged, fin can stop flowing down of condensed water。Therefore no matter parallel-flow heat exchanger is horizontal or is vertically arranged, and is all unfavorable for the discharge of condensed water。And study and show, the frosting of heat exchanger is always from condensing the position that water is assembled, and in this place's frosting the most seriously, therefore the flat tube of Conventional parallel stream heat exchanger is not suitable for being applied in vaporizer with the combination of U-shaped fin。

Therefore, prior art existing defects, need improvement badly。

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:

Fig. 1 is the structural representation of the novel advection heat exchanger in this utility model one preferred embodiment。

Detailed description of the invention

For the ease of understanding this utility model, below with reference to relevant drawings, this utility model is described more fully。Accompanying drawing gives first-selected embodiment of the present utility model。But, this utility model can realize in many different forms, however it is not limited to embodiment described herein。On the contrary, the purpose providing these embodiments is to make to disclosure of the present utility model more thoroughly comprehensively。

It should be noted that be referred to as " being fixed on " another element when element, it can directly on another element or can also there is element placed in the middle。When an element is considered as " connection " another element, it can be directly to another element or may be simultaneously present centering elements。Term as used herein " vertical ", " level ", "left", "right" and similar statement are for illustrative purposes only。

Unless otherwise defined, all of technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present utility model are generally understood that。The purpose describing specific embodiment it is intended merely to herein, it is not intended that in restriction this utility model at term used in the description of the present utility model。Term as used herein " and/or " include the arbitrary and all of combination of one or more relevant Listed Items。
