Description

TECHNICAL FIELD

[0001] The present application relates to a new self-heat-dissipation instant heating module. BACKGROUND

[0002] The high-power nano metal (quartz) coated tube or metal thick film tube and other instant heating application products on the market have four solutions for solving the problem of radiation heat from the heating tube support during operation: 1. Reduce the power density of the surface of the single heating tube by increasing the number of heating tubes or increasing the diameter of the heating tube, thereby reducing the radiation heat of the heating tube to the support, and thus reducing the surface temperature of the support, but the support surface has no heat dissipation; 2. The heating tube support is made of metal to improve the temperature resistance and heat dissipation, but the heat dissipation efficiency is low; 3. The metal support is externally hung with a water circuit to reduce the metal surface temperature; 4. Heat radiation isolation is performed around the heating tube to confine the heat around the heating tube and reduce the heat transfer to the support; The first solution has a more complicated connection between the water circuit and the circuit due to the increase in the number of heating tubes, and the overall size is also increased accordingly; The second and third solutions require the metal support to meet the safety distance requirement between the heating tube, so that the overall size of the instant heating module is also large; It is not suitable for occasions with small space requirements and temperature requirements; Although the fourth solution reduces the heat radiation of the support from the heating tube, the heat is not dissipated and is completely confined around the heating tube, which affects the service life of the heating tube.

[0028] The self-heat-dissipation heating assembly 2 comprises a body assembly 2a and a heating pipe 2b arranged in the body assembly 2a. The body assembly 2a comprises a body 21, an upper cover 22, a lower cover 23, a rear cover 24 and a welding cover 25. The upper cover 22 and the lower cover 23 are respectively connected to two ends of the body 21. The body 21 has a hollow portion, which comprises an inner cavity c1 and an outer cavity c2. The heating pipe 2b is arranged in the inner cavity c1 and fixed. The outer cavity c2 is formed at an outer ring position of the inner cavity. The outer cavity c2 is divided into a first water cooling cavity s1, a second water cooling cavity s2 and a third water cooling cavity s3. The first water cooling cavity s1 and the third water cooling cavity s3 are arranged in the body 21. The second water cooling cavity s2 is arranged on the rear cover. The first water cooling cavity s1 and the third water cooling cavity s3 are not directly communicated with each other. The third water cooling cavity s3 is communicated with the inner cavity c1 in which the heating pipe 2b is arranged. The water flow in the third water cooling cavity finally flows into the heating pipe 2b for heating. The body 21 has a space portion 21a. The rear cover 24 is arranged in the space portion 21a. The second water cooling cavity s2 is formed in the inner side of the rear cover 24. The cavity on the rear cover 24 and the welding cover 25 are ultrasonically welded to form the second water cooling cavity s2. The second water cooling cavity s2 is provided with an inlet s21 and an outlet s22. The inlet s21 is communicated with the first water cooling cavity s1. The outlet s22 is communicated with the third water cooling cavity s3. The first water cooling cavity s1 and the third water cooling cavity s3 are communicated through the second water cooling cavity s2 to form a dynamic water flow circulation.

[0029] The upper cover 22, the body 21 and the lower cover 23 are ultrasonically welded to form the first water cooling cavity s1 and the third water cooling cavity s3. The other side of the lower cover 23 is connected with the water inlet valve body 1. The other side of the upper cover 22 is connected with a water outlet end cover 26. The upper cover 22 and the water outlet end cover 26 are connected by self-tapping screws b1. The water outlet end cover 26 is provided with a water outlet b2. The water heated by the heating pipe can flow out of the water outlet b2 for use. In this way, the water flow flows into the first water cooling cavity s1 from the water inlet 12a of the water inlet end cover. The water flow flows into the second water cooling cavity s2 through the first water cooling cavity s1 and the inlet s21. Then, the water flow flows into the third water cooling cavity s3 through the outlet s22 of the second water cooling cavity s2. Finally, the water flow flows into the heating pipe 2b. The dynamic water flow circulation operation can ensure that the dynamic water flow removes the heat radiated by the heating pipe to the body in the working process in real time, improves the use environment of the heating pipe, effectively prolongs the service life of the heating pipe, reduces the temperature of the outermost side of the body to room temperature, and avoids the influence of high temperature on other matched components around the instant heating module.

[0030] Specifically, referring to the drawings Figure 3 and the drawings Figure 4The first water cooling cavity s1 can form a plurality of first cavities s11, a second cavity s12, a third cavity s13 and a fourth cavity s14 in the outer cavity c2 in sequence, and the cavities are arranged in sequence and communicated with each other; the fourth cavity s14 is communicated with the inlet s21 of the second water cooling cavity, and the outlet s22 of the second water cooling cavity is communicated with the third water cooling cavity s3; in addition, referring to the drawings Figure 7 The fourth cavity s14 and the third water cooling cavity s3 are not communicated with each other and are arranged side by side, and the cavities are separated by a partition plate to form the fourth cavity s14 and the third water cooling cavity s3. The water flows from the water inlet 12a, sequentially flows through the first cavity s11, the second cavity s12, the third cavity s13 and the fourth cavity s14, and then flows into the second water cooling cavity s2 from the fourth cavity s14, and then flows into the heating pipe 2b from the outlet s22. In this way, the water flow path is lengthened to ensure that the water flow can take away the radiation heat radiated to the body, and the heat dissipation efficiency of the entire heating pipe is high.

[0031] Taking a 2100W heating pipe as an example, before the heat dissipation function is added, the temperature of the outer surface of the body of the heating module can reach 100℃ after the heating pipe works continuously for half an hour; and after the heat dissipation structure is used, the temperature of the outer surface of the body of the heating pipe is room temperature under the same conditions. It can be seen that, by arranging a water path in the body (for example, a plastic body), municipal water is circulated in the water path in the body first and then flows into the heating pipe; when the heating pipe works normally, the radiation heat of the heating pipe to the body can be taken away by the water flowing on the surface of the body, so that the temperature of the outer surface of the entire instant heating module can be effectively reduced to room temperature, and the volume of the entire module can be reduced, which can be applied to occasions where space is limited and the temperature of the body shell needs to be raised. In addition, the self-heat-dissipation instant heating module can also adapt to different water flows and water inlet temperatures by monitoring the state of the water inlet valve body, and can adjust the heating power of the heating pipe in real time.

[0032] The above description shows and describes the preferred embodiments of the present application, as described above, it should be understood that the present application is not limited to the forms disclosed herein, and should not be considered as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the inventive concept described herein by the above teaching or related art or knowledge. Any modification and change made by those skilled in the art without departing from the spirit and scope of the present application shall be within the protection scope of the appended claims of the present application.
