Abstract
The invention relates to an opposite-angle A-type aluminum alloy sealing strip, which comprises an elongated body. The cross section of the body is of the shape of a rectangle. The length-to-width ratio of the rectangle is 2:1. V-shaped grooves with the same size are respectively arranged in the centers of two length sides of the rectangle. The depth of each V-shaped groove does not exceed one fourth of the length of each width side of the rectangle. Semicircular grooves with the same size are respectively arranged in the centers of the two width sides of the rectangle. The radius of each semicircular groove does not exceed one fourth of the length of each width side of the rectangle. When the opposite-angle A-type aluminum alloy sealing strip provided by the invention is installed and used, the two V-shaped grooves can evenly dredge heat of hot fluid once, i.e. different heat at the two ends are guided into the V-shaped grooves, the heat is dredged through the V-shaped grooves, and the internal heat and the external heat can be distributed more evenly. Through the semicircular grooves on two sides, the thermal contact area can be increased and the heat transfer is promoted.
Description
Technical field
The present invention relates to a kind of diagonal angle A type aluminium alloy strip of paper used for sealing, is the obturator that is applied on the hot switching path of heat exchanger.
Background technology
The hot switching path of heat exchanger need add strip of paper used for sealing and seal; Because the length restriction of hot switching path adopts soft strip of paper used for sealing, in the process of use owing to the different at different position and different inequality of being heated; Strip of paper used for sealing can produce unequal deformation, also just can not reach good sealing effectiveness.Usually adopt the strip of paper used for sealing of alloy structure in the prior art.But the strip of paper used for sealing of alloy structure is because the restriction of material can not design the structure and the shape of strip of paper used for sealing arbitrarily, so also just brought the contradiction of heat-transfer effect, sealing.When how to guarantee heat-transfer effect, guaranteeing sealing, is the technical problem that the present invention will solve.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of diagonal angle A type aluminium alloy strip of paper used for sealing that guarantees sealing when guaranteeing heat-transfer effect is provided.
The objective of the invention is to realize through following technical scheme:
A kind of diagonal angle A type aluminium alloy strip of paper used for sealing; The body that comprises strip; The cross section of said body is rectangular; And the length-width ratio of rectangle is greater than 2:1, has the identical V-shaped groove of size at the center on two long limits of rectangle, the degree of depth of each said V-shaped groove be no more than rectangle width edge length 1/4th.
Have the identical semi-circular groove of size at the center of two broadsides of rectangle, the radius of each said half slot is no more than 1/4th of rectangle width edge length.
When diagonal angle provided by the invention A type aluminium alloy strip of paper used for sealing is installed and used; Two V-shaped grooves can once evenly be dredged the heat energy of hot fluid; The heat that is about to cold and hot different two ends imports in the V-shaped groove, through V-shaped groove heat energy is dredged, and makes inside and outside heat distribution more balanced.
Through the semi-circular groove of both sides, can increase thermocontact area, promote the conduction of heat.
Description of drawings
According to accompanying drawing and embodiment the present invention is done further explain below.
Fig. 1 is the structure chart of diagonal angle according to the invention A type aluminium alloy strip of paper used for sealing.
The specific embodiment
As shown in Figure 1; The described diagonal angle of embodiment of the invention A type aluminium alloy strip of paper used for sealing; Comprise the body 1 of strip, the cross section of said body is rectangular, and the length-width ratio of rectangle is greater than 2:1; Have the identical V-shaped groove 2 of size at the center on two long limits of rectangle, the degree of depth of each said V-shaped groove 2 be no more than rectangle width edge length 1/4th.
Have the identical semi-circular groove 3 of size at the center of two broadsides of rectangle, the radius of each said half slot 3 is no more than 1/4th of rectangle width edge length.
When diagonal angle provided by the invention A type aluminium alloy strip of paper used for sealing is installed and used; Two V-shaped grooves can once evenly be dredged the heat energy of hot fluid; The heat that is about to cold and hot different two ends imports in the V-shaped groove, through V-shaped groove heat energy is dredged, and makes inside and outside heat distribution more balanced.
Through the semi-circular groove of both sides, can increase thermocontact area, promote the conduction of heat.
Claims (2)
