[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1-Figure 3 A vortex flowmeter for blocking heat transfer shown in the figure comprises a meter head 1 and a support rod 2, on which a plurality of heat sinks 3 are installed at intervals, the heat sinks 3 are circular, and the support rod 2 passes through the center of the heat sink 3; a cover body 4 is detachably installed on the outer side of the support rod 2, and the cover body 4 is a semi-cylindrical shape cut vertically, and two covers 4 can be closed left and right to enclose all the heat sinks 3 and the corresponding part of the support rod 2. A sealing strip 5 is installed on the cross section of the cover body 4 to ensure the sealing of the joint of the cover body 4, and the two covers 4 are fixed by buckles or hoop after closing.

[0018] A plurality of baffles 6 are installed at intervals in the cover body 4, and a through hole 7 is opened on the baffle 6 corresponding to the support rod 2. The diameter of the through hole 7 is larger than the diameter of the support rod 2 so that there is a gap between the baffle 6 and the support rod 2; the diameter of the heat sink 3 is smaller than the inner diameter of the cover body 4 so that there is a gap between the heat sink 3 and the inner wall of the cover body 4; when the cover body 4 is installed on the support rod 2, the plurality of baffles 6 are respectively inserted between two adjacent heat sinks 3, and there is a gap between the baffle 6 and the heat sink 3, and the baffle 6, the heat sink 3 and the cover body 4 form a medium flow channel 8 connected up and down, such as Figure 2 As shown; an inlet pipe 9 is installed on the cover body 4 corresponding to the upper end of the medium flow channel 8, and an outlet pipe 10 is installed on the cover body 4 corresponding to the lower end of the medium flow channel 8. The flowing cooling medium is filled into the medium flow channel 8 through the inlet pipe 9 and leaves from the outlet pipe 10. A cooling device and a pumping device are connected between the inlet pipe 9 and the outlet pipe 10. The cooling device is used to heat exchange and cool the high-temperature cooling medium flowing out of the outlet pipe 10, and then the cooled cooling medium is transported to the inlet pipe 9 through the pumping device to form a cooling cycle, which continuously cools the support rod 2 to prevent the heat from being transferred to the meter head 1. The medium flow channel 8 moves in a bow shape in the cover body 4, increasing the contact area with the heat sink 3, so as to enhance the heat dissipation effect.

[0019] In a high temperature environment, the cover body 4 can be used to enhance heat dissipation, and the cover body 4 can be removed for maintenance and cleaning.

[0020] The upper and lower ends of the cover body 4 are provided with through holes with matching diameters corresponding to the support rod 2, and a sealing seat 11 is installed at the through hole, and a sealing gasket is installed on the inner wall of the sealing seat 11. The inner diameter of the sealing seat 11 matches the outer diameter of the support rod 2, and the sealing gasket prevents internal leakage.

In this embodiment, the number of baffles 6 on one side is one more than the number of heat sinks 3, so that the cooling medium first contacts the baffle 6 when entering, and finally contacts the baffle 6 and then leaves through the outlet pipe 10, which can ensure that both the inlet pipe 9 and the outlet pipe 10 can be installed on the side of the cover body 4.
