Problems solved by technology

[0003] This kind of cold storage achieves the purpose of no commodity energy consumption, but because it uses air ducts for heat exchange, the efficiency is not high. In addition, the air ducts will also form conduction and convection in summer, which will easily cause cooling loss.

Embodiment 1

[0035] As shown in Figure 1, it includes the condensing tube group a2 on the upper right and the evaporating tube group a1 on the lower left. The evaporating tube group a1 includes five evaporating tubes, and the condensing tube group a2 includes five condensing tubes. The tubes are respectively connected in parallel through headers, then the upper headers of the evaporating tube group are connected with the upper headers of the condensing tube group through the rising pipe a3, and the lower headers of the evaporating tube group are connected with the lower headers of the condensing tube group through the downcomer a4 , thus forming a gravity heat pipe circulation loop. In order to ensure that the working medium of the condenser tube group a2 flows back smoothly to the evaporation tube group a1, the condenser tube group a2 is higher than the evaporation tube group a1, and the lower header of the condenser tube group a2 is higher than the upper header of the evaporator tube grou...

Embodiment 2

[0040] As shown in Figure 2, compared with Example 1, the condensing tube group a2 is located directly above the evaporating tube group a1, the riser tube a3 is provided with a communication level gauge a11, and the safety valve a7 and switch are provided above the collecting tube a6 valve a10. The on-off valve can be conveniently filled with working fluid, and the on-off valve can be opened to remove impurity gas as required.

Embodiment 3

[0042] It is equivalent to the two heat pipes shown in Embodiment 1 being connected and connected symmetrically at the evaporating tube group a1. Moreover, as shown in Figure 4, a cooling circulation pipe a12 is concentrically passed through the lower header of the evaporator group a1, and a circulating working fluid a13 is installed inside. Cooling circulation loop, a pump is set in the cooling circulation loop to take out the cold energy in the cold storage body through circulation, so that the cold energy stored in the cold storage body can be sent to a long-distance space that needs cold energy, and it can also make the cold storage body The circulation pipe is connected in series with the condensation end of the secondary heat pipe to form a heat pipe automatic circulation system, which transports cold energy to the evaporation end of the secondary heat pipe.

Abstract

The cold-guiding heat pipe device includes at least two evaporating tubes and condensing tubes to form the evaporating tube set and the condensing tube set separately via parallel connection with the connecting tubes. The upper connecting tubes for the evaporating tube set and the upper connecting tubes for the condensing tube set are communicated, and the lower connecting tubes for the evaporating tube set and the lower connecting tubes for the condensing tube set are communicated to form the circulating loop. Inside the closed container holding cold storing medium, the evaporating tube set is soaked. The refrigerated warehouse includes heat insulator and cold storing body as the cold source. The present invention has heat pipe with high heat conductance and ring circulating loop so that it has high efficiency, high stability, low cost, low power consumption and high performance / cost ratio.

Description

technical field [0001] The invention belongs to refrigerating equipment and parts thereof, in particular to a cold conducting and heat exchanging device, a cold storage body with the cold conducting and heat exchanging device, and a cold store with the cold storage body. Background technique [0002] Most of the existing cold storage bodies and cold storages use compressors for refrigeration. However, due to this technology, it has high energy consumption, high operating costs, unstable operation, complicated maintenance operations, harmful media and noise pollution, and dependence on power engineering. Strong and other shortcomings, so people began to study refrigeration technology without power equipment. The Chinese Invention Patent Application Publication No. 91101569.8 discloses an air duct type natural cooling cold storage, a cooling device consisting of an air duct, a brine infusion tank and a cold storage body. The air pipe performs heat exchange with the brine thro...
