Abstract

The utility model relates to a brazed plate heat exchanger which comprises a plurality of radiators, two medium inlet pipes and two medium outlet pipes, and is characterized in that: two ends of the radiators are respectively connected with the two medium inlet pipes and the two medium outlet pipes. The medium inlet pipes and the medium outlet pipes are respectively positioned at four corners of the radiators which respectively consist of a corrugating sheet and two baffle sheets. The obverse and the inverse of the corrugating sheet are both provided with herringbone corrugating grooves. The brazed plate heat exchanger has the advantages that: the cold water side is additionally provided with a plurality of circuit baffles to form a plurality of separated paths, thereby ensuring the slower flow of liquid in the heat exchanger to fully absorb heat from another passage; a plurality of circuit baffles are reduced in a channel at the heat water side to form 0 to 3 independent paths, thereby ensuring the quick pass of the liquid, enhancing passage flow quantity, improving heat-exchanging efficiency and further avoiding the passage block; and the corrugating grooves on the corrugating sheet are compactly arranged, thereby ensuring the even and quicker emission of heat.

Description

A kind of brazed-plate heat exchanger

Technical field

The utility model relates to a kind of brazed-plate heat exchanger.

Background technology

Heat exchanger has been widely used in industry and civilian installation field, has the function of cold and hot exchange usually.The caliber size of the changes in temperature passage of brazed-plate heat exchanger in the market is identical, if only adopt the mode that adds fat pipe, though also increasing thereupon of flow, and be difficult for stopping up, finally can't reach good heat exchange effect; If only improve heat transfer rate, then passage is less relatively, and flow reduces thereupon, can occur the phenomenon of blocking channel again; In addition, the place not enough at hydraulic pressure also need install booster pump and screen pack additional, causes inefficiency.

The utility model content

The purpose of this utility model provides a kind of brazed-plate heat exchanger, and is less with the pipe passage flow that overcomes existing product, heat transfer rate is low, be prone to the deficiency of pipeline blockage phenomenon.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of brazed-plate heat exchanger, comprise that some fin, two media enter pipe, two medium discharge pipes, described fin two ends connect two media respectively and enter pipe and two medium discharge pipes, described medium enters manages the corner location place that is located at fin with the medium discharge pipe respectively, described fin is made up of corrugated plate and two baffle plate sheets, and the tow sides of corrugated plate are equipped with wave groove.

The beneficial effect of brazed-plate heat exchanger described in the utility model is: cold water side is established several loop baffle plates more, make it to form some independent paths, make fluid slower flowing in heat exchanger, fully absorb the heat of another passage, the pipeline of hot water side reduces some loops baffle plate, make it to be combined into 0-3 independent pathway, the hot fluid of thermal source one side can be flowed to the other end from runner one end fast, and maintenance less resistance, increased channel capacity, improve heat exchanger effectiveness, thereby avoided the phenomenon of pipeline blockage; Wave groove on the corrugated plate is provided with fine and closely woven, makes that heat distributes evenly, speed is very fast.

The specific embodiment

As Figure 1-3, the described brazed-plate heat exchanger of the utility model embodiment, enter 2, two medium discharge pipes 3 of pipe and form by some fin 1, two media, described fin 1 two ends connect two media respectively and enter 2 and two medium discharge pipes 3 of pipe, described medium enters pipe 2 and is located at the corner location place of fin 1 respectively with medium discharge pipe 3, described fin 1 is made up of corrugated plate 5 and two baffle plate sheets 4, and the tow sides of corrugated plate 5 are equipped with chevron shaped wave groove.

Shown in Fig. 3-5, the described brazed-plate heat exchanger of the utility model embodiment, form the Heat Room that communicates at interval between the adjacent baffle plate sheet, four jiaos of each baffle plate sheet are provided with a through hole separately, the periphery of its positive and negative two surfaces and through hole is provided with seal groove, positive and negative two surfaces of each baffle plate sheet are provided with several grooves, two lip-deep grooves of baffle plate sheet are the intersection arrangement mutually about in the Heat Room, the via area at diagonal angle is equal each other on the baffle plate sheet, and the through hole at a pair of diagonal angle each other communicates via Heat Room in each described Heat Room; When structural design, cold water side is established several loop baffle plates more, and the pipeline of hot water side reduces some loops baffle plate, make it to be combined into 0-3 independent pathway, the hot fluid of thermal source one side can be flowed to the other end from runner one end fast, and resistance is very little, has strengthened the heat output of runner; Otherwise the cold fluid pass of low-temperature receiver one side forms some independent paths, and what fluid was slower flows to the other end from an end, can absorb the heat of hot side fully; Fluid media (medium) is through flow through passage between the plate of arm of angle interface, heat exchange is carried out in the reverse flow in adjacent passage of thermal source and low-temperature receiver, the medium pipeline at two ends can be connected on respectively on running water pipe and the steam heating pipe during use, heat exchanger utilizes the heat of heating installation running water to be heated into 30 ℃-65 ℃ domestic water.
