When working, the detector 4 will heat up, and the heat is transferred to the heat-conducting plate 8, which transmits the heat to the heat dissipation pipe 9 for heat dissipation, so as to ensure that the detector is at normal working temperature.

[0003] Since the heat dissipation pipe 9 and the heat-conducting plate 8 are in a split structure, the detector is bumped during assembly or use, a gap is generated between the front end of the heat dissipation pipe 9 and the heat-conducting plate 8, which further reduces the contact surface of the two and the heat conduction is poor, the heat dissipation effect is not ideal, which leads to that the detector cannot work at the set temperature for a long time, and the detection result is affected. UTILITY MODEL CONTENTS

[0004] The utility model provides a kind of detector shell to improve the heat dissipation effect of detector in view of the deficiency of prior art.

[0006] In the installation of the scheme, the probe of the detector is inserted into the heat-conducting plate, and the main body of the detector is located in the heat dissipation sleeve formed by the embedding of the first heat dissipation member and the second heat dissipation member, which is more closed and immune to external interference. Since the heat-conducting plate and the first heat dissipation sleeve are integrated as a whole, there is no gap at the connection between the two, and the heat conductivity is better. In this way, the heat of the detector can be stably transmitted to the first heat dissipation sleeve through the heat-conducting circular plate, and the rear end of the second heat dissipation member is further increased by the sealing plate to further increase the heat dissipation area. After the first heat dissipation member and the second heat dissipation member are embedded with each other, compared with the prior art, the contact surface between the two is greatly increased, which greatly improves the overall heat dissipation performance of the heat dissipation sleeve, and ensures the stability of the detector.

[0008] As an optimization, the end face of the first heat dissipation sleeve is provided with a protrusion extending in the length direction, and the end face of the second heat dissipation sleeve is provided with a groove embedded with the protrusion. This optimization scheme improves the sealing performance of the connection between the first heat dissipation sleeve and the second heat dissipation sleeve by embedding the protrusion and the groove with each other, further reduces the generation of gaps, and thus improves the heat dissipation effect.

[0009] As an optimization, the first heat dissipation member and the second heat dissipation member are both integrally formed structures. This optimization scheme makes the first heat dissipation member and the second heat dissipation member both integral parts, which is convenient to process and has high strength.

[0010] As an optimization, the other side of the heat-conducting circular plate is provided with a probe protection cover. The probe protection cover is provided with an opening at one end close to the heat-conducting circular plate and covers the probe of the detector. A first detection hole is provided at one end of the probe protection cover away from the heat-conducting circular plate.

[0011] As an optimization, the inner cavity of the shell includes a first cavity and a second cavity which are connected in the axial direction. The inner diameter of the first cavity is smaller than that of the second cavity. The probe protection cover is inserted into the first cavity, and the heat dissipation sleeve is inserted into the second cavity. This optimization scheme further protects the probe protection cover and the heat dissipation sleeve by assembling them in the shell, improves the overall strength of the shell, and facilitates overall installation.

[0012] As an optimization, the circumferential outer wall of the probe protection cover close to the heat-conducting circular plate is provided with an outwardly convex protruding ring. The outer diameter of the protruding ring is greater than the inner diameter of the first cavity and smaller than the inner diameter of the second cavity. The heat dissipation sleeve is pressed onto the transition end face of the first cavity and the second cavity. This optimization scheme realizes the fixation of the probe protection cover by pressing the protruding ring on the heat dissipation sleeve.

[0013] As optimization, the heat-conducting round plate is provided with a sunken groove on the side wall close to the probe protective cover, and the thickness of the convex ring is not greater than the depth of the sunken groove. The convex ring is embedded in the sunken groove, the probe protective cover is limited, the position deviation is prevented, and the front end of the heat-dissipating sleeve is attached to the transition end face of the first cavity and the second cavity, so that the stability of the heat-dissipating sleeve after insertion is improved.

[0014] As optimization, the length of the heat-dissipating sleeve is the same as the length of the second cavity. The heat-dissipating sleeve can be completely inserted into the second cavity, and the shell is convenient to install on other equipment in the later period. And because the length is the same, the probe protective cover can be pressed after insertion.

[0015] As optimization, one end of the shell is provided with a shell cover which is threadedly connected with the probe protective cover, and the end of the shell cover is provided with a second detection through hole which is coaxially arranged with the first detection through hole. The shell cover further protects the probe end, and the threaded connection facilitates disassembly and inspection.

[0016] The probe of the detector is inserted into the heat-conducting plate, and the main body of the detector is located in the heat-dissipating sleeve formed by the embedding of the first heat-dissipating piece and the second heat-dissipating piece, so that the sealing performance is better and external interference is avoided. Because the heat-conducting plate and the first heat-dissipating sleeve are integrated, there is no gap at the connection position, and the heat conduction performance is better. In this way, the heat of the detector can be stably transmitted to the first heat-dissipating sleeve through the heat-conducting round plate, and the rear end of the second heat-dissipating piece is further provided with a sealing plate to further increase the heat-dissipating area. After the first heat-dissipating piece and the second heat-dissipating piece are embedded, the contact area between the two is greatly increased compared with the prior art, so that the overall heat-dissipating performance of the heat-dissipating sleeve is greatly improved, and the working stability of the detector is ensured.

[0017] And the probe protective cover is added at the probe to protect the probe and improve the safety of the probe.

[0032] When the first heat-dissipating part 2 and the second heat-dissipating part 3 are embedded, the heat-conducting round plate 21 and the round sealing plate 31 are parallel to each other, the first heat-dissipating sleeve 22 and the second heat-dissipating sleeve 32 are butted together, the end of the first heat-dissipating sleeve 22 away from the heat-conducting round plate 21 is attached to the round sealing plate 31, and the end of the second heat-dissipating sleeve 32 away from the round sealing plate 31 is attached to the heat-conducting round plate 21, thereby forming the cylindrical heat-dissipating sleeve.
