The temperature sensor 120 is directly inserted into the coolant tank H through a hole on the other side of the coolant tank H to sense the temperature of the coolant. In order to prevent the coolant from leaking at the hole, a plurality of sealing rings 130 are usually used for sealing. However, in the actual installation and use process, the above-mentioned high-pressure liquid heater 100 still has the following shortcomings:

[0003] 1. In order to install the temperature sensor 120, it is necessary to additionally process holes on the coolant tank H and seal it with multiple sealing rings, which increases the preparation cost and makes the installation more complicated;

[0004] 2. There is a risk of leakage at the holes;

[0005] 3. Since the temperature sensor 120 is far away from the heating element 110, there is a lag in measuring the temperature of the heating element 110, and the measurement accuracy is low;

[0006] 4. When there is no coolant around the heating element 110 , the temperature sensor 120 cannot accurately detect the temperature of the heating element 110 , so protective measures cannot be taken in time, causing the heating element 110 to dry burn and be damaged.

[0036] The following describes the implementation of the present disclosure through specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification.

[0037] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings attached to this specification are only used to match the contents disclosed in the specification for the understanding and reading of those skilled in the art, and are not used to limit the conditions under which the present disclosure can be implemented. Therefore, they have no substantive technical significance. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical contents disclosed in the present disclosure without affecting the effects and purposes that can be achieved by the present disclosure.

[0038] For the convenience of description, the drawings of the present disclosure simplify or omit components commonly used in the art accordingly, and these omitted or simplified components do not affect the understanding of the contents of the present disclosure by those skilled in the art.

[0039] The present disclosure provides a heating assembly for a high-pressure liquid heater. Embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings.

[0040] See also Figure 1 and Figure 2The heating assembly 1 includes an end cover 10, a heating part 20 and a connecting terminal 40. The end cover 10 may be roughly circular and used for sealing connection with the coolant tank (also called the shell) of the high-pressure liquid heater. For example, it may be sealed connected to the coolant tank by welding or locking elements (e.g., screws). The heating part 20 is fixed to the first side of the end cover 10 and is used to heat the coolant in the coolant tank. In one embodiment, the heating part 20 may include a spiral body 21 and two end parts 22 connected to both ends of the spiral body 21 and fixed to the end cover 10. Of course, the present disclosure is not limited to the above-mentioned structure of the heating part 20, as long as it can heat the coolant.

[0041] The two ends 22 of the heating unit 20 are respectively provided with connection terminals 40. Figure 1 As shown, the connection terminal 40 is located on the second side of the end cover 10 and is used to connect an external power source to energize the heating part 20. The second side of the end cover 10 is opposite to the first side.

[0042] The heating assembly 1 further includes a mounting portion 30 fixed to the end cover 10. Figure 1 and Figure 2 As shown, the mounting portion 30 and the heating portion 20 are located on the same side of the end cover 10. The mounting portion 30 is used to mount a temperature sensor, and the mounting portion 30 is disposed close to the heating portion 20 so that the temperature sensor installed later can sense the temperature of the heating portion 20.

[0043] In one embodiment, the mounting portion 30 may be a hollow structure with one end open and the other end closed, for example, a tubular structure with a first opening 301, and such a configuration can reduce the complexity of the structure and facilitate its manufacture. The tubular structure can be sealedly connected (for example, welded) to a mounting hole on the end cover 10, or the tubular structure can be integrally formed with the end cover 10 to prevent the coolant from leaking at the connection between the tubular structure and the end cover 10 when the heating component 1 is installed on the coolant tank. The mounting portion 30 or the first opening 301 of the tubular structure is exposed on the second side of the end cover 10, so that the operator can accommodate and install the temperature sensor in the mounting portion 30, and at the same time, the risk of leakage caused by directly inserting the temperature sensor into the coolant tank can be avoided, and there is no need to process additional holes for inserting the temperature sensor on the coolant tank, and there is no need to use sealing rings, which effectively reduces costs and improves the sealing of the coolant.

[0044] In this embodiment, if Figure 1 As shown, the first opening 301 of the mounting portion 30 is flush with the surface S of the second side of the end cover 10, however, the present disclosure is not limited thereto, for example, the first opening 301 of the mounting portion 30 may also protrude from the surface of the second side of the end cover 10, as long as the first opening 301 is exposed on the second side of the end cover 10, it is convenient to place the temperature sensor.

[0045] Please continue to see Figure 1 and Figure 2 The mounting portion 30 extends along the central axis of the spiral body 21 of the heating portion 20 and is surrounded by the spiral body 21. This arrangement allows the temperature sensor subsequently placed in the mounting portion 30 to be close to the heating portion 20, reducing the delay caused by temperature transfer and improving the measurement accuracy. In a preferred embodiment, the mounting portion 30 can contact / close to the heating portion 20, so that the temperature sensor placed in the mounting portion 30 can measure the temperature of the heating portion 20 more accurately, and when there is no coolant around the heating portion 20, the temperature of the heating portion 20 can be sensed to rise rapidly, so that protective measures can be taken in time to avoid dry burning and damage to the heating portion 20. It should be noted that the mounting portion 30 can be made of a metal material with good thermal conductivity to avoid energy loss during heat transfer.

[0046] Although the mounting portion 30 in the above embodiment of the present disclosure is described as a hollow structure with one end open and the other end closed, the present disclosure is not limited to this. For example, the mounting portion 30 may also be a hollow structure with both ends open and / or openings at other locations, or may also be a solid structure, as long as the temperature sensor can be fixedly installed.

[0047] In addition, the mounting portion 30 in the above-mentioned embodiment of the present disclosure is described as extending along the central axis of the spiral body 21 and being surrounded by the spiral body 21, but the present disclosure is not limited to this. For example, the mounting portion 30 may also extend in other directions and / or be located on the periphery of the spiral body 21, as long as it is arranged close to the heating portion 20.

[0048] It can be seen that the heating component provided by the present disclosure includes a mounting portion, and the mounting portion is arranged close to the heating portion, so that the temperature sensor subsequently placed in the mounting portion can be close to the heating portion, reducing the delay caused by temperature transfer and improving the measurement accuracy. When there is no coolant around the heating portion, the temperature of the heating portion can be sensed to rise rapidly, and protective measures can be taken in time to avoid dry burning and damage to the heating portion. In addition, the heating component of the present disclosure is configured to have a mounting portion as a tubular structure with a first opening, and the first opening is exposed on the second side of the end cover. Such a configuration makes it easy for the operator to accommodate and install the temperature sensor in the mounting portion, while avoiding the risk of leakage caused by directly inserting the temperature sensor into the coolant tank body, and there is no need to process additional holes on the coolant tank body for inserting the temperature sensor, and there is no need to use a sealing ring, which can effectively reduce the preparation cost.

[0049] The present disclosure also provides a high-pressure liquid heater including the above-mentioned heating assembly. In order to clearly describe the relative positional relationship between the heating assembly and the temperature sensor in the high-pressure liquid heater, common components such as the coolant tank / shell are omitted in the drawings of the embodiments described in the present disclosure. The embodiments of the present disclosure are described in detail below in conjunction with the drawings.

[0050] See also Figures 3 to 4B The high-pressure liquid heater comprises a coolant tank / shell (not shown), the above-mentioned heating assembly 1 and a temperature sensor 2. The heating assembly 1 is mounted on the shell, specifically, the end cover 10 of the heating assembly 1 is sealedly mounted on the shell, and the heating part 20 and the mounting part 30 of the heating assembly 1 are located in the shell and directly contact the coolant in the shell. The temperature sensor 2 is fixed to the mounting part 30 of the heating assembly 1, and is used to accurately measure the temperature of the heating part 20 and the coolant.

[0051] In one embodiment, if Figures 4B to 6 As shown, the temperature sensor 2 can be fixed inside the mounting portion 30 via a fixing member 3, wherein the fixing member 3 is made of a metal material with good thermal conductivity. Specifically, the fixing member 3 includes a sleeve 31 and at least one metal spring 32 (the present disclosure is described with two metal springs 32, but is not limited thereto). The sleeve 31 is fastened to the periphery of the temperature sensor 2, and its shape may depend on the periphery shape of the temperature sensor 2. In the present embodiment, the sleeve 31 is roughly annular cylindrical, but the present disclosure is not limited thereto. The metal spring 32 is connected to the sleeve 31 and extends along a first direction X toward a position deviating from the sleeve 31, wherein the first direction X is opposite to the direction in which the temperature sensor 2 is inserted into the mounting portion 30. The metal spring 32 thus arranged can not only serve as a guide to facilitate the insertion of the temperature sensor 2 into the mounting portion 30, but also when the temperature sensor 2 is inserted into the interior of the mounting portion 30, the metal spring 32 will abut / abut against the inner wall of the mounting portion 30, resulting in deformation, so that the temperature sensor 2 can be fixed at any position in the mounting portion 30 as required. The metal spring pieces 32 can be evenly arranged around the outer circumference of the sleeve 31. Figure 6 As shown, the present disclosure is not limited thereto, as long as the temperature sensor 2 can be fixed.

[0052] See also Figure 4A and Figure 5, the high-pressure liquid heater also includes a seal 4 and a sensor connection terminal 5. In the present embodiment, the seal 4 is used to fix the sensor connection terminal 5, and can prevent dust, particles, etc. from entering the mounting portion 30. Of course, if the mounting portion 30 has other openings at the position located on the first side of the end cover 10, the seal 4 can also prevent the leakage of the coolant in the shell. Specifically, the seal 4 is sealingly fixed to the first opening 301 of the mounting portion 30, the sensor connection terminal 5 passes through the seal 4, and one end of the sensor connection terminal 5 is located in the mounting portion 30 and is electrically connected to the temperature sensor 2, and the other end is located outside the mounting portion 30 (that is, outside the seal 4) for connecting external components.

[0053] Since the high-pressure liquid heater disclosed herein includes a heating assembly with a temperature sensor installed / integrated therein, the temperature sensor can accurately measure the temperature of the heating part to avoid dry burning and damage to the heating part. At the same time, it can also avoid additional processing of holes on the shell of the high-pressure liquid heater for inserting the temperature sensor, and there is no need to use a sealing ring, thereby improving the sealing of the coolant and reducing the preparation cost.

[0054] Although the above embodiment of the present disclosure uses the fixing member 3 to fix the temperature sensor 2 in the mounting portion, the present disclosure is not limited thereto. For example, the temperature sensor 2 may also be fixed inside the mounting portion 30 via a thermally conductive adhesive.

[0055] The above describes exemplary implementations of the heating assembly and the high-pressure liquid heater provided by the present disclosure with reference to preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the appended claims.
