Abstract
The utility model relates to a heat exchanger plate, which is mainly used for forming a plate-typed heat exchanger or an evaporator for an air conditioner and comprises first flow passages (5) and angle holes (6), wherein the plate is provided with second flow passages (7) surrounding the angle holes (6) at positions close to outer corners of the plate, and the second flow passages (7) are communicated with the first flow passages (5) in a circular mode to form an integrated flow passage. After the heat exchanging plate are stacked and assembled to be welded into a heat exchanger, the periphery of the angle holes of the heat exchanger is formed into the second flow passages which enables liquid such as water and the like to flow so that the liquid can flow smoothly in the second flow passages to reduce dead angles for liquid to flow, thereby not only effectively reducing icing phenomena of the liquid in the second flow passages caused by freezing, but also increasing heat exchanging area and improving heat exchanging efficiency.
Description
(1) technical field
The utility model relates to heat exchanger structure and improve especially a kind of sheet structure of plate-type evaporator.Be mainly used in refrigeration air-conditioner and make board-like (heat exchanger) evaporimeter.Belong to the heat transmission equipment technical field.
(2) background technology
In the refrigeration air-conditioner running; big city uses board-like (heat exchanger) evaporimeter now; and plate-type evaporator in use; be very easy to because the freezing point of system protection control inaccuracy or current are not smooth; cause fluorine side-entrance water Yin Wendu on every side to cross low and the icing phenomenon of generation; plate is broken, cause in the evaporimeter and leak, thereby whole refrigeration system is destroyed.
Fig. 1 is a heat exchanger plate chip architecture schematic diagram generally commonly used, design has as shown in the figure sealing surface 1 and first flow 5 on plate, intensity and forming technology requirement in order to increase plate simultaneously also designed groove 2, groove 3, groove 4 structures of being interrupted on plate.Weld together when many heat exchange plate stacks and by modes such as solderings, form sealing surface and confined space and heat exchange runner around the hole, heat exchanger angle.But, in daily plate production process, wearing and tearing or the not high reason of Mould Machining precision owing to the plate mould, boundary at sealing surface can form aperture (similar shrinkage cavity) defective, in the heat exchanger use, water or other fluid in the heat exchange runner can penetrate into confined space by said aperture, causes stagnant water.Water in this confined space is not because there is flowability, meets when cold, is very easy to freezing and expansion and plate is burst, and causes plate to change interior leakage, and the water fluorine is ganged up mutually, thereby refrigeration system is destroyed.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can effectively prevent or reduce the heat exchanger plate chip architecture that the icing phenomenon of heat exchanger takes place.
The purpose of this utility model is achieved in that a kind of heat exchanger plate, comprise first flow and hole, angle, described plate is provided with around the runner in hole, angle near plate outer corners place in the Qi Jiao hole, and runner is designed to encircle logically mutually with first flow, forms a whole runner.
The utility model heat exchanger plate, described second runner has two kinds of versions: a kind of second runner is groove structure, and another kind of second runner is the tongue structure, and second runner of two kinds of versions is separately positioned on the place, diagonal angle of described plate.
The beneficial effects of the utility model are:
After heat exchange plate stack assembling is welded into heat exchanger, around hole, heat exchanger angle, form second runner of liquid communication such as can supplying water, make the liquid such as water can smooth and easy circulation in second runner, reduced the fluid flow dead angle, not only effectively reduce freeze because of the catching a cold generation of phenomenon of fluid in second runner, also increase heat exchange area, improved heat exchange efficiency.
(4) description of drawings
Fig. 1 is general heat exchanger plate chip architecture schematic diagram commonly used.
Fig. 2 is the utility model heat exchanger plate chip architecture schematic diagram.
Reference numeral among the figure:
Sealing surface 1, groove 2, groove 3, groove 4, first flow 5, hole, angle 6, second runner 7,7A.
(5) specific embodiment
Referring to Fig. 2, Fig. 2 is the utility model heat exchanger plate chip architecture schematic diagram.As seen from Figure 2, the utility model heat exchanger plate is characterized in that the groove on the plate shown in Figure 12, groove 3, groove 4 structures are communicated with first flow 5, forms a whole runner.When many heat exchange plates weld together by Rotate 180 ° stack and by modes such as solderings successively, simultaneously, the second runner 7A that is provided with at the place, diagonal angle of second runner 7 of described plate is the tongue structure.The groove structure of second runner 7 at close plate outer corners place pastes mutually with the second runner 7A tongue structure of another heat exchange plate in hole, plate angle shown in Figure 2, form the second heat exchange runner around hole, angle 6, the ring that the second heat exchange runner is designed to communicate with the first heat exchange runner leads to the type flow passage structure, water or other fluid can flow freely in runner, does not form the fluid dead angle.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design, make some alternative or obvious modification that are equal to; and performance or purposes are identical, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of being submitted to.
Claims (2)
1. heat exchanger plate, comprise first flow (5) and hole, angle (6), it is characterized in that: described plate is provided with second runner (7) around hole, angle (6) at Qi Jiao hole (6) close plate outer corners place, described second runner (7) is designed to and first flow (5) Xiang Huantong, forms a whole runner.
2. a kind of heat exchanger plate according to claim 1, it is characterized in that: described second runner (7) has two kinds of versions: a kind of second runner (7) is groove structure, another kind of second runner (7A) is the tongue structure, and second runner of two kinds of versions is separately positioned on the place, diagonal angle of described plate.
