Abstract
Provided is a heat exchanger square hole seal. The heat exchanger square hole seal comprises a long-strip-shaped body. The cross section of the body is in the shape of a rectangle. A rectangular square hole is arranged in the center of the cross section of the body. The proportion between length of the rectangular square hole and width of the rectangular square hole is 3:1. The distance between the inner wall of the rectangular square hole and the outer surface of the body is half of the width of the rectangular square hole. One wide side of the body is chamfered. The radius of a chamfer is the half of the width of the body, so that a half circular column shape is formed. The body is made of aluminum alloy material. When the heat exchanger square seal is installed and used, a half circular column shape side is arranged at a hot fluid end of a heat exchanged channel. Due to the fact that the superficial area of a half circular column structure is increased and the half circular column shape is of symmetric structure, heat at the hot fluid end can be guided into the rectangular square hole in a well-distributed mode. The heat can be rapidly dissipated through the big cross section of the rectangular square hole.
Description
Technical field
The utility model relates to a kind of heat exchanger square hole 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 to 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 positions 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 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 problems to be solved in the utility model.
For the problems referred to above, the applicant has applied for a kind of diagonal angle A type aluminium alloy strip of paper used for sealing, but diagonal angle A type aluminium alloy strip of paper used for sealing can not perfectly solve all problems, and can not be applied in the larger heat exchanger channel of some heat exchange amounts, the heat conduction that little V-shaped groove can carry out, the effect of evacuating are limited.So the applicant designs for the seal structure of some large-scale heat exchangers.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of heat exchanger square hole strip of paper used for sealing that guarantees sealing when guaranteeing heat-transfer effect is provided.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of heat exchanger square hole strip of paper used for sealing, the body that comprises strip, the cross section of described body is rectangle, kernel of section at body has the rectangle square hole, the length-width ratio of described rectangle square hole is 3:1, and the internal face of described rectangle square hole is half of rectangle square hole width apart from the distance of this external surface, and a broadside of described body carries out rounding, chamfer radius is half of body width, namely forms half-cylindrical.
Described body is the aluminum alloy material body.
When the heat exchanger square hole strip of paper used for sealing that the utility model is provided is installed and used, semi-cylindrical one side is installed in the hot fluid end of heat exchanger channel, because the increase of semi-cylindrical structural table area, and half round post is symmetrical structure, the heat of hot fluid end is imported in the rectangle square hole uniformly, by the heavy in section of rectangle square hole, this part heat is evacuated fast.
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 heat exchanger square hole strip of paper used for sealing described in the utility model.
The specific embodiment
As shown in Figure 1, the described heat exchanger square hole of the utility model embodiment strip of paper used for sealing, the body 1 that comprises strip, the cross section of described body 1 is rectangle, has rectangle square hole 2 at the kernel of section of body 1, and the length-width ratio of described rectangle square hole 2 is 3:1, the internal face of described rectangle square hole 2 is half of rectangle square hole width apart from the distance of this external surface, a broadside of described body 1 carries out rounding, and chamfer radius is half of body width, namely forms half-cylindrical 3.
Described body 1 is the aluminum alloy material body.
When the heat exchanger square hole strip of paper used for sealing that the utility model is provided is installed and used, semi-cylindrical one side is installed in the hot fluid end of heat exchanger channel, because the increase of semi-cylindrical structural table area, and half round post is symmetrical structure, the heat of hot fluid end is imported in the rectangle square hole uniformly, by the heavy in section of rectangle square hole, this part heat is evacuated fast.
Claims (2)
1. heat exchanger square hole strip of paper used for sealing, the body that comprises strip, it is characterized in that, the cross section of described body is rectangle, has the rectangle square hole at the kernel of section of body, and the length-width ratio of described rectangle square hole is 3:1, the internal face of described rectangle square hole is half of rectangle square hole width apart from the distance of this external surface, a broadside of described body carries out rounding, and chamfer radius is half of body width, namely forms half-cylindrical.
2. heat exchanger square hole strip of paper used for sealing as claimed in claim 1 is characterized in that, described body is the aluminum alloy material body.
