Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, a test tube heating apparatus 100 according to a preferred embodiment of the present invention includes a base 110, a heating element (not shown), and an elastic heat-conducting sleeve 120.
The base 110 serves as a support and a load-bearing, and is generally formed of metal or plastic. The susceptor 110 is formed with a plurality of heating pipes 111 having one end opened. The test tube to be heated may be inserted into the heating tube 111 through the opening of the heating tube 111. The heating duct 111 may be formed by directly perforating the surface of the susceptor 110, or the heating duct 111 may be formed by surrounding a plate-shaped material.
In the present embodiment, a working surface 113 is formed on a side of the base 110 facing away from the bottom, the heating pipe 111 is formed inside the base 110, and an opening of the heating pipe 111 is located on the working surface 113.
Specifically, the base 110 may be a cube, and the bottom thereof refers to the side of the base 110 that contacts the ground or the work bench when the test tube heating apparatus 100 is in normal use. Since the heating duct 111 is formed inside the base 110, the test tube heating apparatus 100 can be made compact. Moreover, the base 110 surrounds the heating pipeline 111, which is more beneficial to heat preservation of the test tube in the heating pipeline 111.
The heating assembly is disposed on the susceptor 110, and the heating assembly is used for heating an inner wall of the heating pipe 111. Wherein the heating component is typically an electrical heating element. For example, the heating element may be a heating wire wrapped around the outer wall of the heating conduit 111.
In the present embodiment, the base 110 is a hollow structure, and the heating element is accommodated inside the base 110. Accordingly, the susceptor 110 may provide protection to the heating assembly. Meanwhile, the base 110 can also serve as a receptacle, which makes the structure of the test tube heating apparatus 100 more compact.
The plurality of elastic heat conduction sleeves 120 are accommodated in the plurality of heating pipes 111, respectively. The elastic heat conductive sleeve 120 is formed of a material having elasticity and capable of conducting heat. The elastic heat conductive sleeve 120 is a hollow cylindrical structure with at least one end open. The outer wall of the elastic heat conducting sleeve 120 is attached to the inner wall of the corresponding heating pipeline 111, and one opening of the elastic heat conducting sleeve 120 is in the same direction as the opening of the corresponding heating pipeline 111.
The outer diameter of the elastomeric heat conductive jacket 120 is generally slightly smaller than the inner diameter of the corresponding heating conduit 111. Thus, the elastic heat-conducting sleeve 120 can be inserted into the heating pipe 111 and pressed to make the outer wall of the heating pipe 111 abut against the inner wall of the heating pipe 111. Thus, the inner wall of each heating conduit 111 acts as a radiating layer of resilient heat conductive material. When the heating assembly is activated, heat can be conducted from the heating pipe 111 to the inner wall of the elastic heat-conducting sleeve 120.
The elastic heat-conducting sleeve 120 is a wearing part and may be damaged after long-term use. Therefore, to facilitate replacement, in particular in the present embodiment, each elastomeric thermal jacket 120 is removable with respect to the corresponding heating conduit 111.
The tube diameter of the test tube to be heated is generally slightly larger than the caliber of the elastic heat-conducting sleeve 120, and the test tube passes through the openings of the heating pipeline 111 and the elastic heat-conducting sleeve 120 and is loaded into the heating pipeline 111. When the test tube is loaded into the heating tube 111, the test tube may press and deform the corresponding elastic heat-conductive sleeve 120. The deformed elastic heat-conducting sleeve 120 tightly wraps the tube wall of the test tube. That is to say, the elastic heat conducting sleeve 120 has a larger contact area with the tube wall of the test tube and makes more uniform contact, thereby realizing uniform and rapid heating of the test tube.
In the embodiment, the elastic heat-conducting sleeve 120 is a heat-conducting sponge sleeve. The heat conduction sponge is soft in texture, so that the test tube can be conveniently extruded. Moreover, the sponge has a honeycomb structure inside. Therefore, when heat is transferred from the inside of the heating pipe 111 to the elastic heat-conductive sleeve 120, the temperature rise process of the elastic heat-conductive sleeve 120 is more smooth.
Further, the amount of deformation of the elastic heat conductive sleeve 120 may vary within a certain range. The deformation amount varies according to the degree of pressing. Therefore, test tubes with a tube diameter within a certain range can be inserted into a certain heating pipeline 111 and wrapped by the corresponding elastic heat-conducting sleeve 120. That is to say, the same heating pipeline 111 can heat test tubes of different types (different tube diameters), so the application range of the test tube heating device 100 is wider.
In this embodiment, each of the elastic thermal sleeves 120 is open at one end. That is, when the test tube to be heated is inserted into the heating tube 111, the bottom thereof is also in contact with the elastic heat-conductive sleeve 120. Therefore, the elastic heat conducting sleeve 120 has better cladding performance on the test tube, and is beneficial to further improving the heating speed and uniformity.
In the present embodiment, the plurality of heating pipes 111 have different pipe diameters. When the tube diameter of the test tube to be heated is beyond the deformation range of the elastic heat-conducting sleeve 120, the test tube can be inserted into the heating tube 111 with a larger inner diameter. Therefore, the applicable range of the test tube heating apparatus 100 can be further expanded.
Further, in the present embodiment, the plurality of heating pipes 111 are arranged along a straight line, and the inner diameters of the plurality of heating pipes 111 increase or decrease in the arrangement direction of the plurality of heating pipes 111.
As shown in fig. 1, the number of the heating pipes 111 in the present embodiment is four, and the inner diameters of the four heating pipes 111 decrease sequentially from left to right. Specifically, the heating pipes 111 with different inner diameters are arranged according to a certain rule, so that the operators can quickly identify the heating pipes 111 with the inner diameters equivalent to the outer diameters of the test tubes, and the operation efficiency is improved.
In the above test tube heating apparatus 100, the tube diameter of the test tube to be heated is generally slightly larger than the caliber of the elastic heat-conducting sleeve 120. Therefore, when the test tube is loaded into the heating tube 111, the test tube may press and deform the corresponding elastic heat-conductive sleeve 120. The deformed elastic heat-conducting sleeve 120 tightly wraps the tube wall of the test tube. That is, the contact area between the elastic heat-conducting sleeve 120 and the tube wall of the test tube is large. After heating element starts, the heat is transmitted to elastic heat conduction sleeve 120 by the inner wall of heating tube 111 to evenly conduct to the test tube by elastic heat conduction sleeve 120, thereby realize evenly, heating fast to the test tube. Also, the amount of deformation of the elastic heat-conductive sleeve 120 may vary according to the degree of compression. Therefore, the test tubes with a tube diameter within a certain range can be inserted into the heating pipeline 111 and wrapped by the corresponding elastic heat-conducting sleeve 120, so that the application range of the test tube heating device 100 is wider.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
