[0031] The following combination Figure 1-Figure 5 The invention provides a heater capable of rapid cooling.

[0032] like Figure 1 、 Figure 3 and Figure 4 As shown, in one embodiment, a heater capable of rapid cooling includes a housing 100 , a heating tube 200 , a heat pipe 300 and a combination plate 400 .

[0033] The housing 100 has a heating chamber 110 and a hollow chamber 120 .

[0034] The heating tube 200 is located in the hollow cavity 120 , and a heating wire 210 is formed on the inner wall of the heating tube 200 .

[0035] The heat pipe 300 is located on the outer wall of the heating pipe 200 , and the heat pipe 300 and the heating pipe 200 are coaxial.

[0036] The combined plate 400 is fixed to the outer wall of the shell 100 and has a docking joint 410 , an inlet pipe 420 and an outlet pipe 430 . The docking joint 410 is electrically connected to the free end of the heating wire 210 , and the inlet pipe 420 and the outlet pipe 430 are both connected to the cooling chamber 310 .

[0037] A cooling cavity 310 is formed between the heating tube 200 and the heat conducting tube 300 .

[0038] After use, the fast-cooling heater can quickly cool the heating tube 200 by injecting cooling gas or cooling liquid into the inlet pipe 420, so that the cooling fluid is injected into the cooling cavity 310, thereby improving the safety performance of the heater. At the same time, the heating tube 200 can protect the heating wire 210, and during the heating process, the heat pipe 300 can prevent the heating wire 210 from directly contacting the shell 100, thereby increasing the service life of the shell 100.

[0039] In this embodiment, see Figure 5 The heating tube 200 is spirally wound in the hollow cavity 120 , and the heating wire 210 and the heat conducting tube 300 have the same shape as the heating tube 200 , and are coaxial with the heating tube 200 .

[0040] The spiral winding method can, on the one hand, make the temperature in the heating chamber 110 more uniform, and on the other hand, allow the fluid to spiral down along the inner wall of the heat pipe 300 during rapid cooling, thereby improving the cooling efficiency.

[0041] In this embodiment, see Figure 3 and Figure 4 The inner wall of the shell 100 has an inclined groove 130, which is connected to the hollow cavity 120. A condensation water pipe 140 is fixedly connected to the bottom of the shell 100, which is connected to the inclined groove 130. A stop valve 440 is installed on the condensation water pipe 140, the inlet pipe 420 and the outlet pipe 430.

[0042] During the rapid cooling process, water droplets are likely to appear on the outer wall of the heat pipe 300. When these water droplets fall to the inner bottom wall of the shell 100, they are collected in the condensation water pipe 140 along the inclined groove 130. Finally, the stop valve 440 of the condensation water pipe 140 is opened to facilitate the discharge of the condensation water accumulated in the condensation water pipe 140.

[0043] It should be supplemented that, in order to improve the heating efficiency when heating solid materials in the heating chamber 110 , a plurality of through holes 150 are opened on the inner wall of the shell 100 , and the through holes 150 are interconnected with the hollow cavity 120 .

[0044] In this embodiment, in order to facilitate heating of liquid substances, a first groove 160 is opened on the surface of the shell 100, and a heat-conducting liner 500 is arranged in the heating chamber 110. The surface of the heat-conducting liner 500 has a support plate 510, which is snapped into the first groove 160. The outer wall of the heat-conducting liner 500 is in contact with the inner wall of the shell 100.

[0045] In this embodiment, a positioning block 520 is fixedly connected to the bottom of the support plate 510 , and a positioning groove 170 that is interference-fitted with the positioning block 520 is formed on the surface of the housing 100 .

[0046] During use, the liquid substance to be heated is added to the heat-conducting inner liner 500, and then the positioning block 520 is snapped into the corresponding positioning groove 170. At this time, the support plate 510 is just snapped into the first groove 160, and the liquid substance is conveniently heated through the heat-conducting inner liner 500, and at the same time, the heated liquid substance is conveniently transferred.

[0047] In this embodiment, the surface of the shell 100 has a cover body 600, and the surface of the cover body 600 has a handle 610. The shell 100 and the cover body 600 are both provided with threaded holes 670, and the threaded holes 670 are internally threaded with screws 630. A temperature sensor 680 is installed on the cover body 600.

[0048] By screwing the screw 630 into the corresponding threaded hole 670, the cover 600 can be conveniently fixed on the shell 100, and the temperature sensor 680 can be used to conveniently monitor the temperature in the heating chamber 110 in real time, thereby conveniently adjusting the temperature in the heating chamber 110 as needed.

[0049] In this embodiment, a second groove 620 is provided on the surface of the shell 100, and a third groove 640 is provided at the bottom of the cover body 600. When the cover body 600 is covered on the shell 100, the second groove 620 and the third groove 640 are combined to form a sealing groove 650, and a sealing ring 660 is provided in the sealing groove 650.

[0050] During the process of fixing the cover 600 to the housing 100 , the sealing ring 660 is snapped into the corresponding sealing groove 650 , thereby improving the sealing performance of the heater.

[0051] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that variations and improvements are possible within the scope of the present invention, as would be apparent to one skilled in the art. These variations and improvements fall within the scope of the present invention. Therefore, the scope of the present invention shall be determined by the appended claims.
