The first bottom plate 111, the first arched plate 112, the two first side plates 113, and the plurality of first arc-shaped plates 120 are integrally formed. For example, the controller housing 100 can be integrally formed using injection molding, resulting in high structural strength, suitability for mass production, and low cost. The first arched plate 112 can be a semi-circular plate with a semi-circular cross-sectional profile. The concave arc surface of the first arched plate 112 forms a first groove, which is a semi-circular groove. It should be understood that there can be two first arched plates 112, arranged side-by-side, with a first spacer 114 separating the two first arched plates 112. Two first arched plates 112 are located between two first side plates 113, which protrude below the first base plate 111. The first groove of each first arched plate 112 faces away from the first base plate 111. Furthermore, each first groove contains multiple first arc-shaped plates 120, which are spaced apart along the length of the groove.

The second shell body 210 includes two second arched plates 211, two second side plates 212, a first baffle 213, and a second baffle 214. The two second arched plates 211, two second side plates 212, first baffle 213, second baffle 214, and a plurality of second arc-shaped plates 220 can be integrally molded by injection molding, resulting in high structural strength and low manufacturing cost. The first baffle 213 and the second baffle 214 are opposite each other, the two second side plates 212 are opposite each other, and the two second arched plates 211 are located in the area enclosed by the first baffle 213, the second baffle 214, and the two second side plates 212. The two second arched plates 211 are arranged side by side and separated by a second spacer 217, on which a notch 218 is provided. Each second arched plate 211 can be a semi-circular plate, and the concave arc surface of each second arched plate 211 forms a second groove, which is a semi-circular groove. Multiple second arched plates 220 are located within the second groove and are arranged at intervals along the axial direction of the second groove.

[0034] It should be understood that the number of the second arc-shaped plates 220 is selected as needed. For example, in this embodiment, the number of the second arc-shaped plates 220 in each second groove is five.

[0035] Meanwhile, the first baffle 213 is provided with an inlet pipe 215 and an outlet pipe 216. The second baffle 214 is provided with two positioning through holes 219.

[0036] Furthermore, the water chamber shell 200 also includes two second retaining plates 230, which are located within the second groove and on one side of all the second arcuate plates 220, forming a second retaining groove 231 between the two second retaining plates 230. The two second retaining plates 230 can be annular plates, and the two second retaining plates 230 are integrally formed with the corresponding second arched plates 211.

[0037] In this embodiment, optionally, the baffle plate 300 is provided with a first diversion hole 310 and a plurality of second diversion holes 320 arranged around the first diversion hole 310. Both the first diversion hole 310 and the second diversion hole 320 can be circular holes, which are easy to process. The cross-sectional area of ​​the first diversion hole 310 is smaller than the cross-sectional area of ​​the hollow region 011, and the cross-section is a plane perpendicular to the axis of the spiral flow channel 001.

[0038] The assembly structure of the heater housing provided in this embodiment is as follows: Please combine Figure 6Two first arched plates 112 and two second side plates 212 are inserted into the area enclosed by the first baffle 213, the second baffle 214 and the two second side plates 212. The two first side plates 113 and the two second side plates 212 are respectively attached. The two ends of the first arched plate 112 are respectively closed by the first baffle 213 and the second baffle 214. The first arched plate 112 and the second arched plate 211 are attached. The first spacer 114 and the second spacer 217 are attached. The two first arched plates 112 and the two second arched plates 211 respectively cooperate to form two flow channels. Multiple first arc plates 120 and multiple second arc plates 220 in each flow channel are connected one by one to form a spiral plate, finally forming two spiral flow channels 001. The two spiral flow channels 001 are side by side and connected at the gap 218. The baffle 300 is simultaneously engaged in the first slot 131 and the second slot 231, and is located between the inlet pipe and the spiral flow channel 001. In other words, the two ends of the spiral flow channel 001 are the first port and the second port, respectively. The second ports of the two spiral flow channels 001 are connected through the notch 218, and the first ports of the two spiral flow channels 001 are the inlet and the outlet, respectively. The inlet pipe 215 is connected to the inlet, and the outlet is connected to the outlet pipe 216.

[0039] In practical applications, two heating tubes 400 pass through two positioning through holes 219 and are inserted into the hollow region 011. The first arc plate 120 and the second arc plate 220 are in contact with the outer peripheral surface of the heating tubes 400. The heating tubes 400 are hollow inside and have connecting holes 410 connecting the inner and outer sides. The spiral flow channel 001 connected to the inlet pipe 215 is designated as the first channel, and the spiral flow channel 001 connected to the outlet pipe 216 is designated as the second channel. When the coolant flows, it enters through the inlet pipe 215, passes through the first diversion hole 310 into the heating tubes 400, and passes through the second diversion hole 320 into the first channel. The coolant in the heating tubes 400 can be discharged from the connecting hole into the first channel. The coolant in the first channel enters the second channel through the notch 218. Some coolant can also enter the heating tubes 400 that cooperate with the second channel. Finally, the coolant is discharged from the outlet pipe 216. During the flow of the coolant, the contact area with the heating element 400 is large, resulting in high heat exchange efficiency.

[0040] It should be noted that, in order to better distribute the coolant and ensure that a sufficient amount of coolant enters the spiral flow channel 001 from the second diversion hole 320, the cross-sectional area of ​​the first diversion hole 310 is smaller than the cross-sectional area of ​​the heating pipe 400's cavity.

[0041] Furthermore, it should be noted that in some embodiments, the number of spiral flow channels 001 can be one or more, which can be designed as needed. When there are multiple spiral flow channels 001, the multiple spiral flow channels 001 are connected in series.

[0042] The heater housing provided in this embodiment has a simple structure, is easy to assemble, and has low maintenance costs. At the same time, the coolant has a long flow path, resulting in high heat exchange efficiency.
