Summary of the invention
The technical problem to be solved in the present invention
; in cold-storage heat exchanger in the past; as shown in patent documentation 1 grade, on two sides' of cool storage material container side plate, be respectively equipped with from tabular surface outstanding multiple protuberances laterally, and the roof of protuberance is connected with the plat part soldering (ろ う pay け) of refrigerant pipe.Between the tabular surface of two sides' side plate and refrigerant pipe, form respectively air duct.
, there is following problems in this cold-storage heat exchanger in the past.
(1) owing to protuberance being arranged on the two sides of cool storage material container in the space of Rack, so cause accordingly the volume of cool storage material container to reduce, the enclosed volume of cool storage material tails off, and cold-storage ability reduces.Particularly, since be provided with air duct, in order to make the air duct water slug that is not condensed, channel width (height of protuberance) need to be guaranteed, the volume of cool storage material container can be further reduced like this.
(2) because the roof of the protuberance with vessel side carries out being connected between cool storage material container and refrigerant pipe, therefore contact area is little, heat transfer efficiency is low.
In view of described problem, the object of this invention is to provide a kind of cold-storage heat exchanger, it can increase the enclosed volume of cool storage material and can improve heat transfer efficiency.
The technical scheme of technical solution problem
Cold-storage heat exchanger of the present invention comprises: the refrigerant pipe of multiple flat, so that the relative mode of plat part is arranged side by side with the interval of regulation; And cool storage material container, be configured in the space between the plat part of adjacent refrigerant pipe of a part, to enclose and have cool storage material, cold-storage heat exchanger of the present invention is using this content as prerequisite.
Described cool storage material container comprises: the first side plate of a side refrigerant pipe side; And the second side plate of the opposing party's refrigerant pipe side, described the first side plate has tabular surface, and by the refrigerant pipe brazing of this tabular surface and one, described the second side plate has multiple protuberances of giving prominence to laterally from tabular surface, and by the roof of this protuberance and described the opposing party's refrigerant pipe brazing, between the tabular surface of described the second side plate and described the opposing party's refrigerant pipe, be formed with air duct.
Invention effect
According to the present invention, due in two sides' of cool storage material container side plate (the first side plate and the second side plate), only on the side plate (the second side plate) of folk prescription, be formed with outstanding laterally protuberance, so can guarantee the volume of cool storage material container, increase the enclosed volume of cool storage material, thereby can improve cooling performance.
In addition,, due in two sides' of cool storage material container side plate (the first side plate and the second side plate), tabular surface and refrigerant pipe brazing for the side plate (the first side plate) of folk prescription, so contact area increase can improve heat transfer efficiency.
On the other hand, although air duct is only formed on the folk prescription side of cool storage material container, but just because of only at one-sided formation air duct, so can strengthen accordingly channel width (height of protuberance), can guarantee thus the performance of the performance direct cooling to air and reduction aeration resistance.In addition,, by strengthening channel width, can also prevent that condensed water from stopping up.

(1) due in first side plate 11 and the second side plate 12 and the 3rd side plate 13 of the both sides of cool storage material container 5, only on the second side plate of a side and the 3rd side plate 13, be formed with laterally outstanding protuberance 12b (with recess 13c), so can guarantee the volume of cool storage material container 5, increase the enclosed volume of cool storage material, and can improve cooling performance.
(2), due in first side plate 11 and the second side plate 12 and the 3rd side plate 13 of the both sides of cool storage material container 5, the first side plate 11 use tabular surface 11a and refrigerant pipe 3L brazing of a side, so contact area increases, can improve heat transfer efficiency.
(3) although air duct 16 is only formed on folk prescription one side of cool storage material container 5, but one-sided just because of being only formed on, so can strengthen accordingly channel width (height of protuberance 12b and recess 13c), can guarantee the performance of the performance direct cooling to air and reduction aeration resistance.In addition,, by strengthening channel width, can prevent that condensed water from stopping up, and can guarantee drainage performance.
On the other hand, if cool storage material container 5 inside are hollow, exist for external pressure and in be pressed with the problem that may not maintain shape, need to there is enough intensity.
Therefore,, in cool storage material container 5, between the first side plate 11 and the second side plate 12, strength enhancing structure is set.As strength enhancing structure, can adopt the structure shown in the first embodiment～three embodiment.
But, in present embodiment (Fig. 9), adopted the structure identical with the second embodiment.
That is, multiple recess (pit) 11c that give prominence to the inside from the tabular surface 11a of the first side plate 11 are set, and interior by the tabular surface 12a brazing of the diapire of recess 11c and the second side plate 12 at cool storage material container 5.
In addition, multiple recess (pit) 12c that give prominence to the inside from the tabular surface 12a of the second side plate 12 are set, and interior by the tabular surface 11a brazing of the diapire of recess 12c and the first side plate 11 at cool storage material container 5.
In addition, illustrated embodiment is illustration of the present invention, and except directly illustrating by the embodiment as above illustrating, the present invention is also included in various improvement and the distortion within the scope of claim, implemented by those skilled in the art certainly.
For example protuberance 12b (with recess 11c, 12c, 13c) is expressed as typically truncated cone in diagram, but is not limited to this.
