Abstract
The utility model discloses an arrowhead sealing strip for an internal channel of a plate-fin heat exchanger. The arrowhead sealing strip is fixed at each end of the internal channel of the plate-fin heat exchanger and is matched and connected with the internal channel of the plate-fin heat exchanger. The arrowhead sealing strip comprises a strip-shaped sealing strip body, wherein the front end of the sealing strip body is of an arrowhead shape; wing parts are respectively arranged at the two sides of the arrowhead shape; the lower part of the sealing strip body is a rectangular lug; the width of the rectangular lug is less than the width of the wing parts; and the sealing strip body is made of an aluminum alloy material. When the arrowhead sealing strip for the internal channel of the plate-fin heat exchanger provided by the utility model is used, the arrowhead-shaped upper part and the rectangular lug-shaped lower part of the sealing strip are respectively matched and connected with two panels of the internal channel of the heat exchanger, the connection precision can be guaranteed, welding after connection is facilitated, and the depth achieved by fusion welding is more than the depth of a common tabular sealing strip, so the welding effect is better and the process is simple.
Description
Technical field
The utility model relates to a kind of plate-fin heat exchanger internal channel arrow strip of paper used for sealing, is the obturator of plate-fin heat exchanger.
Background technology
The heat exchanger that plate-fin heat exchanger is comprised of plate and fin heat transfer element.Have the advantages such as heat transfer efficiency height, advantages of compact and light structure, strong adaptability.But shortcoming is also very obvious, comprises
(1) manufacture process requirement is strict, complex technical process.
(2) the easy obstruction is not corrosion-resistant, and the cleaning maintenance is very difficult, so can only be used for clean, less scaling without burn into, the difficult deposition of heat transferring medium, not susceptible to plugging occasion.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of plate-fin heat exchanger internal channel arrow strip of paper used for sealing that can reduce process complexity is provided.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of plate-fin heat exchanger internal channel arrow strip of paper used for sealing, be fixed on the two ends of plate-fin heat exchanger internal channel, be connected with the plate-fin heat exchanger internal channel, the strip of paper used for sealing body that comprises strip, the front end of described strip of paper used for sealing body is arrowhead form, and be respectively equipped with alar part in the both sides of arrowhead form, and the bottom of strip of paper used for sealing body is the rectangle projection, the width of described rectangle projection is less than the width of alar part.
Described strip of paper used for sealing body is the aluminum alloy material body.
When the plate-fin heat exchanger internal channel arrow strip of paper used for sealing that the utility model is provided is installed and used, the bottom of the sagittate top of strip of paper used for sealing body and rectangle projection shape is connected with two panels of heat exchanger internal channel respectively, the precision that connects can be guaranteed, can be so that weld after the connection, the degree of depth of the tabular strip of paper used for sealing that the depth ratio that melting welding will reach is common is darker, so welding effect is better, technique is simple.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is the structure chart of plate-fin heat exchanger internal channel arrow strip of paper used for sealing described in the utility model.
The specific embodiment
As shown in Figure 1, the described a kind of plate-fin heat exchanger internal channel arrow strip of paper used for sealing of the utility model embodiment, be fixed on the two ends of plate-fin heat exchanger internal channel 1, be connected with plate-fin heat exchanger internal channel 1, comprise the strip of paper used for sealing body 2 of strip, the front end of described strip of paper used for sealing body 2 is arrowhead form, and is respectively equipped with alar part 3 in the both sides of arrowhead form, the bottom of strip of paper used for sealing body 2 is rectangle projection 4, and the width of described rectangle projection 4 is less than the width of alar part 3.
Described strip of paper used for sealing body 2 is the aluminum alloy material body.
When the plate-fin heat exchanger internal channel arrow strip of paper used for sealing that the utility model is provided is installed and used, the bottom of the sagittate top of strip of paper used for sealing body and rectangle projection shape is connected with two panels of heat exchanger internal channel respectively, the precision that connects can be guaranteed, can be so that weld after the connection, the degree of depth of the tabular strip of paper used for sealing that the depth ratio that melting welding will reach is common is darker, so welding effect is better, technique is simple.
