As shown in Figure 1 and Figure 2 The sample thawing device of the embodiment comprises a base 1, a supporting plate 11 spaced above the base 1, and a plurality of supporting portions 111 arranged on the supporting plate 11, and each supporting portion 111 is used for supporting a test tube in a vertical state.

[0037] Here, the test tube is supported by arranging the supporting plate 11, which avoids the problem that the experimental personnel need to hold the test tube throughout the thawing process, and improves the operation convenience.

[0038] Meanwhile, a plurality of heating portions 12 are arranged between the supporting plate 11 and the base 1, each heating portion 12 corresponds to each supporting portion 111, and each heating portion 12 is used for heating the part of the test tube below the supporting portion 111. In this way, the heating portion 12 and the supporting portion 111 are arranged one by one, which can realize batch thawing of the test tube, and the setting of the heating portion 12 ensures the temperature consistency of each region in the test tube and improves the stability of thawing.

[0039] Based on the above overall introduction, in the embodiment, as a preferred implementation form, as shown in Figure 2 each heating portion 12 includes a heating pipe 121 arranged between the supporting plate 11 and the base 1, and the heating pipe 121 extends along the height direction of the base 1.

[0040] Specific implementation, the test tube is placed in the supporting portion 111, and the part of the test tube below the supporting portion 111 will be wrapped by the heating pipe 121, so as to thaw the sample in the test tube.

[0041] To be specific, in the embodiment, as a preferred implementation form, as shown in Figure 3 the heating pipe 121 is in a spiral shape, so that the heat transfer area can be more fully utilized, the heat transfer efficiency is improved, and the uniform distribution of heat is promoted, and the temperature of each region of the test tube is kept consistent.

[0042] Further, in the embodiment, as a preferred implementation form, as shown in Figure 2 it also includes a circulating device 2, and the circulating device 2 includes a serpentine pipe 21 arranged on the supporting plate 11 and connected to the top of each heating pipe 121, a flow channel 1312 arranged in the base 1 and connected to the bottom of each heating pipe 121, and a circulating pump group 23 connected between the serpentine pipe 21 and the flow channel 1312.

[0043] Here, by setting the circulating device 2, the consumption of working fluid can be reduced, which saves energy, and the setting of the serpentine pipe 21 can reduce the resistance of the flow channel 1312, thereby improving the transmission efficiency of the pipeline. In specific implementation, the circulating pump group 23 is connected with an inlet pipe 231 for flowing working fluid into the circulating pump group 23, and an outlet pipe 232 for flowing working fluid from the circulating pump group 23 into the serpentine pipe 21.

[0044] It is worth mentioning that the working fluid mentioned in the sample thawing device of the embodiment can refer to the heat exchange medium known to those skilled in the art, such as water and oil.

[0045] Further, in the embodiment, as a preferred implementation form, as shown in Figure 2As shown, the base 1 is provided with a plurality of first interfaces 132 connected with the flow channel 1312, and each first interface 132 is connected with each heating pipe 121 one by one. Here, the first interface 132 is connected with the heating pipe 121 one by one, so as to ensure that the working liquid in each heating pipe 121 flows into the flow channel 1312.

[0046] Specifically, in the embodiment, as a preferred implementation form, as shown in Figure 4 As shown, the base 1 includes a bottom plate 13 with a groove 131, and a cover plate 14 provided on the bottom plate 13 for covering the flow channel 1312, and the bottom plate 13 is provided with a plurality of blocking strips 1311 located in the groove 131, and the groove 131 is formed by the blocking of each blocking strip 1311 to form the flow channel 1312.

[0047] The advantage of such arrangement is that it can avoid the working liquid flowing around in the flow channel 1312, and can reduce the flow rate of the working liquid in the flow channel 1312, thereby improving the efficiency of heating the working liquid.

[0048] It is worth mentioning here that the number of blocking strips 1311 can be designed and adjusted according to the actual heating demand of the working liquid, for example, three or four, to meet the demand for sufficient heating of the working liquid.

[0049] In specific implementation, two side walls 4 in the width direction of the groove 131 are respectively provided with two blocking strips 1311, and each blocking strip 1311 is staggered and spaced.

[0050] In addition, in the embodiment, as a preferred implementation form, as shown in Figure 4 As shown, one end of the bottom plate 13 in the length direction is provided with a first water outlet 1313 communicating with the flow channel 1312, the first water outlet 1313 is located in the middle of the width direction of the bottom plate 13, and the groove 131 is provided with a first flow guide strip 1314 and a second flow guide strip 1315 for guiding the working liquid to flow to the first water outlet 1313.

[0052] Secondly, in the embodiment, as a preferred implementation form, each blocking strip 1311 is a heating strip, which is convenient for fully heating the working liquid in the flow channel 1312, improving the heat exchange efficiency, and thereby improving the thawing efficiency.

[0053] It is still worth mentioning that the heating strip mentioned in the sample thawing device of the embodiment can refer to the heating element known to those skilled in the art, such as a stainless steel heating rod, a quartz heating rod, etc., to meet the requirement of heating the working liquid under the soaking of the working liquid.

[0054] In addition, in the embodiment, as a preferred internal implementation form, as shown in Figure 1 Each supporting part 111 is a supporting opening provided on the supporting plate 11, which is arranged to facilitate the placement and support of the test tube and reduce the consumption of labor. In the specific operation, the test tube is placed in the supporting opening, and the lower part of the test tube is inserted into the heating pipe 121 and wrapped by the heating pipe 121. When heating, the experimental personnel no longer need to hold the test tube throughout the process, thereby avoiding being scalded.

[0055] As a preferred implementation form, as shown in Figure 1 and Figure 2 As shown in the bottom plate 13 of the embodiment is provided with a second water outlet 1316. Here, the second water outlet 1316 is arranged to facilitate the replacement of the working liquid after the thawing process is completed, thereby improving the overall convenience of the device.

The serpentine pipeline 21 is provided with a second interface 211 corresponding to each heating pipe 121. The working liquid flows into the heating pipe 121 through each second interface 211. The working liquid flowing through each heating pipe 121 converges into the groove 131 and is heated in the groove 131. Under the guidance of the flow channel 1312 and the guide strip in the groove 131, the working liquid enters the inlet pipe 231 through the first water outlet 1313, and then flows into the circulating pump group 23 through the inlet pipe 231.

[0057] Under the action of the circulating pump group 23, the working liquid flows into the serpentine pipeline 21 through the outlet pipe 232. The working liquid flows into the heating pipe 121 through each second interface 211 again, and finally converges in the groove 131. Thus, the circulation is completed. The sample thawing device of the embodiment thaws the test tube wrapped by the heating pipe 121 through the above-mentioned manner, thereby ensuring the temperature consistency of each region in the test tube and improving the stability of thawing.

[0058] The above only describes the preferred embodiment of the utility model, and does not limit the utility model.
