Problems solved by technology

However, when considering the convenience of market service, it is not preferable to use a special pressurizing device
In addition, it is not preferable to heat the container from the viewpoint of safety because there is a risk of rupture of the container and the risk of a jetting accident of the working fluid.
[0015] In addition, such a problem also arises in an equipment temperature control device that is installed in a place other than a vehicle or that adjusts the temperature of equipment other than a battery.
In addition, such a problem also occurs in an equipment temperature control device having a circuit of a working fluid that constitutes a non-annular thermosiphon heat pipe.

no. 1 approach

[0056] figure 1 The device temperature adjustment device 1 according to the present embodiment shown here adjusts the battery temperature of the battery pack BP, which is a device to be temperature adjusted, by cooling the battery pack BP mounted on the vehicle. An electric vehicle or a hybrid vehicle that uses the battery pack BP as a power source and can run with a running motor (not shown) is assumed as a vehicle equipped with the device temperature adjustment device 1 .

[0057] The battery pack BP is constituted by stacking a plurality of rectangular parallelepiped battery cells BC. A plurality of battery cells BC constituting the battery pack BP are electrically connected in series. Each battery cell BC constituting the battery pack BP is composed of a chargeable and dischargeable secondary battery (for example, lithium ion battery, lead battery). In addition, the battery cell BC is not limited to a rectangular parallelepiped shape, and may have other shapes such as a ...

no. 2 approach

[0112] Such as Figure 8 As shown, the condensation unit 13 for equipment in this embodiment is different from that in the first embodiment. The other configurations of the facility temperature regulator 1 are the same as those of the first embodiment.

[0113] The facility temperature adjustment device 1 includes an air-cooled condenser 14 as the facility condensation unit 13 . The condenser 14 is a heat exchanger for exchanging heat between the working fluid and the blown air blown to the condenser 14 . The condenser 14 is selectively blown with outside air and cool air lower than the outside air as blown air. The cold air is generated by the refrigeration cycle device 21 . The cool air is cooling air for cooling the working fluid.

[0114] Specifically, the facility temperature adjustment device 1 includes a switching device 51 that selectively switches between outside air and cool air as the blown air to be blown to the condenser 14 . The switching device 51 is provid...

no. 3 approach

[0124] Such as Figure 9 As shown, the condensation unit 13 for equipment of this embodiment is different from that of the first embodiment. The other configurations of the facility temperature regulator 1 are the same as those of the first embodiment.

[0125] The facility temperature control device 1 includes: a water-cooled condenser 61 as the facility condensation unit 13 ; and a cooling water circuit 62 through which cooling water circulates. Cooling water is a cooling liquid containing water. The coolant is a liquid heat medium for transferring heat. For example, antifreeze, water, etc. are used as cooling water. The condenser 61 is a heat exchanger that condenses the working medium in the facility fluid circuit 10 by exchanging heat between the working medium and the cooling water in the cooling water circuit 62 . The condenser 61 has a working fluid side heat exchange part 61a through which the working fluid of the equipment fluid circuit 10 flows, and a cooling wa...

Abstract

The manufacturing method of the equipment temperature regulating device of the present invention includes the steps of connecting the filling port (36) of the circuit (10) with the container (45) containing the working fluid in the gaseous phase, and filling the inside of the circuit (10) with the working fluid . The loop (10) constitutes a heat pipe of thermosiphon type, and circulates the working fluid. In the filling process, the working fluid inside the circuit (10) is cooled by the cooling source (21). The internal temperature of the circuit (10) is made lower than the internal temperature of the container (45), so that the internal pressure of the circuit (10) is lower than the internal pressure of the container (45).

Description

[0001] Cross-reference of related applications [0002] This application is based on Japanese Patent Application No. 2016-176791 filed on September 9, 2016, and the contents of the description are hereby incorporated by reference into this application. technical field [0003] The invention relates to a manufacturing method of an equipment temperature regulating device for adjusting the temperature of equipment. Background technique [0004] Patent Document 1 discloses a temperature adjustment device for adjusting the temperature of a battery mounted on a vehicle. This temperature adjustment device is provided with a working fluid circuit, and the working fluid circuit constitutes an annular thermosiphon heat pipe. This circuit has: an evaporator in which the working fluid evaporates by absorbing heat from the battery; and a condenser in which the working fluid evaporated in the evaporator is cooled and condensed.
